Generator Voskhod G-427

Generator G-427 alternating current with excitation from a permanent magnet with an inductive sensor of the electronic ignition system. In the grooves of the stator, assembled from stamped electrical steel plates, eight coils are placed, which form four independent circuits: – power supply to the ignition storage capacitor; – lighting and sound signal; – direction indicators; – brake signal.

Voltage regulation in the circuits of lighting loads is carried out according to the principle of parametric regulation, i.e. The winding data of the generator are selected in such a way that as the rotor speed increases, the voltage at the generator terminals changes within certain limits for a certain load. Attaching the generator stator to the engine crankcase provides adjustment of the ignition timing.

On the generator stator cover there are terminals: – charging coils of the power supply circuit for the Voskhod ignition storage capacitor; – direction indicators; – brake signal; – lighting; – sensor.

Which are marked accordingly: >, >, >, > and >.

The sensor is mounted on the generator stator cover using screws.

Generator rotor

The generator rotor with the sensor rotor located on it is mounted on the right axle axis of the engine crankshaft with a bolt and is secured against rotation by a key.

Incendiary physics - advance, distributor and UOZ

How to set the ignition? What is UOZ? Where did the runners rotate in domestic cars? What does the expression “set by spark” mean? - there are many interesting questions to which owners of modern cars may not give the correct answers.

What is ignition timing - also known as ignition timing? Is this some kind of attribute of ancient cars or something unshakable, akin to universal gravity? Most modern car owners are unaware of this. All car systems are controlled by numerous controllers, and therefore timely sparking in the engine cylinders is entirely their responsibility. Meanwhile, a huge number of ancient machines are running around the country, unfamiliar with processors and other chips. Therefore, questions like “How to regulate the SOP?” still sound today.

It's always a pleasure to answer technical questions. But first you have to remember some “incendiary” terms.

Terminology

Ignition distributor

- an electromechanical device that ensures timely supply of high voltage pulses to the spark plugs.
It is often called a distributor
.

Contact and non-contact distributors for rear- and all-wheel drive carburetor VAZ cars

Ignition advance

- ignition of the working mixture in the cylinder before the compression stroke ends.

Ignition timing (IDA)

— the angle of rotation of the engine crankshaft from the position corresponding to the appearance of a spark on the spark plug until the piston reaches top dead center.

Caring for a sunrise motorcycle generator - how to remove, what to check and install correctly

Generator maintenance mainly comes down to tightening the threaded fasteners of the generator stator and rotor, as well as the wire terminals.

In order to remove the generator, you must:

disconnect the wires of the ignition circuit, sensor, brake light and direction indicators from the generator terminals;
unscrew the three screws securing the stator to the crankcase and remove the stator;
Unscrew the bolt securing the generator rotor and, with light, careful blows of a wooden hammer on opposite sides of the rotor, remove it from the trunnion and remove the key.

Checking the removed parts

After removing the generator stator and rotor, wash the parts with clean gasoline and carefully inspect them. Disassemble the wire fastening terminals on the stator. Wipe dry all insulating parts of the terminals.

Generator installation

Installation is carried out in the reverse order, in this case it is necessary:

check the runout of the generator rotor, which should be no more than 0.1 mm with the bolt secured;
tighten the generator stator without distortions, ensuring a tight fit to all three supports;
install the ignition correctly;
The generator wires must be securely fastened and well insulated from each other.

The generator wires must be securely fastened and well insulated from each other.

Ignition adjustment Voskhod

The ignition timing is set by turning the generator stator after first loosening the three screws securing the stator to the crankcase. For normal engine operation, it is necessary that the moment of spark formation (on the generator, this moment is determined by the coincidence of the sensor rotor groove with the protrusion on the sensor coil frame. Fig.) coincides with the moment when the piston does not reach the top dead center of 2.5-3.0 mm (at running the engine on gasoline with an octane rating of 92).

The gap between the rotor and the core of the sensor coil should be within 0.3±0.05mm.

The gap should be set as follows:

loosen the screws securing the sensor stator to the generator stator cover;
By moving the sensor stator in the grooves of the generator stator cover, set the required gap, and then tighten the fastening screws.

For more accurate ignition installation, it is recommended to determine the piston position with the cylinder head removed.

Coil Voskhod - high-voltage transformer B-300B

The high voltage transformer is located under the fuel tank and is used to convert low voltage current into high voltage current. The transformer consists of a core, primary and secondary windings, a housing and a cover with terminals. During operation it does not require maintenance and cannot be repaired.

Switch Voskhod - electronic KET-1

The electronic switch KET-1 is designed to work in the ignition system complete with the G-427 generator and the B-300B high-voltage transformer. Allows you to obtain a secondary voltage of up to 18 kV, at a generator rotor speed of 250 to 7500 rpm. The switch is installed in the right toolbox. The base of the commutator is connected to the ground of the motorcycle. If the switch fails, it can be disassembled and repaired

The electronic switch has three output terminals with letter markings on the body >, > and >. The ground terminal is the base of the switch.

Maintaining the switch during operation comes down mainly to tightening the threaded connections, while avoiding stripping the threads. It is necessary to protect the switch from moisture getting inside it and onto the terminals from sudden shocks and exposure to high temperatures. You should also systematically check the reliability of the electrical connection of the switch base with >, because If this condition is violated, sparking on the spark plug stops.

Spark plug Voskhod - spark ignition type A-23

During operation, the spark plug must be periodically cleaned of carbon deposits and the gap between the electrodes must be adjusted, which should be within 0.6-0.7 mm, which is ensured by bending the outer electrode. To seal, a copper-asbestos gasket is placed between the spark plug and the cylinder head. To eliminate radio interference created by the ignition system, a shielded tip of type A-4 is placed on the spark plug.

A little bit about everything

Since VK complains about the size of the page being created, we have to resort to using LiveJournal again. So, let's say you bought an old Voskhod. According to the seller, it starts and drives (we will not consider options when the motorcycle is faulty and needs serious repairs in this material). How to assess his condition? How to understand what needs repair and what is “still fit”? Excellent material from the book by V. S. Zakharin and G. A. Pilyukevich “Motor tourism: sports and recreation” will help with this (you can download the book in the group’s documents. Read online here). I took the liberty of slightly redoing and adding to the original text, since it still talks about some general things, and we are interested in a specific brand of motorcycle. The original text is about preparing the motorcycle for long trips, so don't be surprised by some of the wording. But before you start studying the material below, download and read the motorcycle instruction manual - now it is your bible. You can download the instructions for your modification of the Voskhod motorcycle in the same place as the book from which the article was taken.

“It is advisable to adhere to the following sequence of motorcycle inspection: engine, electrical equipment, power system, brakes, chassis, tires, general fasteners. When examining, try not to miss the little things. Engine

. The engine of your motorcycle starts well, runs steadily in all modes, has good compression, you don’t hear any extraneous knocks, and it doesn’t smoke excessively. This means there will be little work. First, remove the cylinder head and cylinder. Let's check the radial clearance in the bearing of the lower end of the connecting rod. The limit value is considered to be 0.25-0.3 mm. Note; does the connecting rod stem touch the surface of the crankshaft cheeks? Radial play in the connecting rod upper head assembly should not be felt by hand. Only rocking of the piston without audible clicks is permissible. The piston must have uniform traces of running-in and carbon deposits on the right and left sides, i.e. in the plane of the piston pin, traces of carbon deposits on the side surface of the piston can only be in the area of the rings. If they are lower, then it is necessary to find out why the piston rings do not function well as seals. It is possible that some of their sections have “buried”, that is, they have lost mobility in the piston groove. Such a ring must be carefully removed, gradually rocking it, and the groove must be thoroughly cleaned. The best way to do this is with a piece of the piston ring. Just make sure that it doesn’t turn out to be the one you removed.

Carbon marks below the rings, located on one side of the piston, may also indicate the presence of a misalignment in the cylinder. To verify this, you need to remove the rings, install the cylinder, press it to the surface of the crankcase using bushings (the internal diameter is slightly larger than that of the stud, and the length is approximately equal to the height of the cylinder head bosses) and nuts. Rotate the crankshaft several times. Set the piston to top dead center and, pressing your finger at an angle on the bottom of the piston, press it against one side of the cylinder in the plane of the piston pin. If there is no misalignment, the piston will remain in its occupied position after removing the pin from its bottom. If there is a misalignment, it will spontaneously return to its original position as soon as you remove your finger. Repeat this operation, pressing the piston against the opposite side of the cylinder. Identifying the causes of the malfunction will require a thorough inspection of the crankcase, cylinder, and piston, and the distortion can be eliminated by straightening the connecting rod, installing gaskets under the cylinder, and adjusting parts. Unfortunately, we cannot describe this work in a similar way, because our article has a different purpose. Having installed the piston ring in the lower, less worn part of the cylinder, where there are no windows, we will check the size of the gap in the ring lock. For a new engine it is usually set within 0.2-0.4 mm. If the gap approaches 2-3 mm, then it is usually recommended to replace the ring. This, in our opinion, does little to increase engine power, since the new ring will not be able to get used to the worn surface of the cylinder, which has acquired a complex shape, for a long time. How to be? If the piston ring has reached the limit of wear, then the cylinder probably needs repair. Move the ring to the top of the cylinder, 0.5-1 mm short of the ring mark (the so-called “step”) at top dead center. Measure the gap in the ring lock, subtract the value of the previously measured (below) gap and divide the difference by 3.14. Obtain the cylinder wear value. If it is more than 0.25 mm, then it makes sense to start boring and honing it or buy a new one. You can read about boring at home here. It is necessary to check the amount of radial play in the main bearings of the crankshaft (especially in the right one), since it greatly affects the operation of the ignition system, which has a breaker (if the ignition is contact). Typically, the limit is considered to be a backlash of up to 0.06 mm (in new bearings the backlash is 0.008-0.022 mm). Also, if there is noticeable play, the tightness of the oil seal through which the engine will suck in air will be compromised, which greatly affects the stability of the engine. If you are in doubt about the tightness of the crank chamber, fill it with diesel fuel or fuel mixture from the motorcycle tank and note the level. A significant decrease in the level after a few hours will indicate a leak, and oil traces on the outside of the oil seal or gasket will indicate its place. The right oil seal and main bearing can be replaced without completely disassembling the engine. A gasket leak can sometimes be fixed by thoroughly degreasing the area, lubricating it with epoxy glue or sealant, and carefully tightening the mounting screws. On parts such as crankcase halves or covers, tightening begins from the middle of the part, tightening the screws located crosswise, and gradually moving to more distant ones. It is best to tighten it in several stages, gradually increasing its torque. But if possible, it is better to replace the gasket. Now reassemble the disassembled components, lubricating the rubbing surfaces with engine oil. Before assembly, do not forget to clean the exhaust ports, the piston crown and the surface of the combustion chamber in the cylinder head from carbon deposits. Clutch

.
Check the condition of the clutch discs. If there is significant wear on the lateral friction surfaces (cork, plastic), protrusions, or the absence of one of the protrusions, replace the discs. If in the grooves of the drive drum there is wear from the disc protrusions with a depth of more than 0.1 mm (the so-called “saw”), level their surface using a flat file. This operation is not easy and requires painstaking work. Here it is necessary to ensure that the clutch disc, after alignment, is adjacent to the grooves of the drum with all its protrusions at the same time, otherwise uneven distribution of the load can lead to breakage of the protrusions and breakage of the clutch. Therefore, if possible, it is better to replace such a clutch drum with a serviceable one. Carefully adjust and lubricate the clutch drive. With the clutch disengaged, check whether the pressure plate is distorted. Motor transmission
.
Check the condition of the teeth of the drive and driven chain sprockets and the condition of the chain. When the lower branch of the chain is tense, the sagging of the upper branch should not exceed 20 mm. This is checked using a rod attached to the top branch and a ruler. By the presence of wear on the end surfaces of the sprockets, one can judge that the sprockets are not in the same plane. Using washers or other measures, try to install them correctly. Transmission
. If the gears are switched with great effort or sometimes switch off on their own, you cannot drive. Since it is in this component of motorcycle engines that there are the greatest differences, our recommendations can only be of a very general nature. Engines in which the clutch “leads”, the latch sticks, or the gears move tightly along the shafts require a lot of effort when changing gears. Self-disengagement of gears occurs when the cams are not fully engaged or if their edges are chipped or “licked”. The complete engagement of the cams is usually adjusted by installing washers under the stops of the gearbox shaft bearings (under the retaining rings or covers). You can read about gearbox adjustment here. With any design, it is necessary to leave room for axial movement of the shaft of 0.1-0.2 mm. Usually the biggest trouble is caused by the self-switching of fourth gear. In this case, remove the secondary shaft sprocket, spacer sleeve, and oil seal and push the outer bearing race inside the gearbox. The freed space is filled with adjusting washers. Gears with worn cam edges are best replaced. Sometimes the shape of the cams is straightened using a cutting stone so that the side (working) surface forms an angle of 3–5° with the end of the gear.

Setting up BSZ Voskhod 3M

In 1983, the Kavrovsky plant launched the modernized Voskhod 3M motorcycle. The purpose of the modernization was to improve the operational and technical characteristics of the Voskhod motorcycle. The platform for creating the motorcycle was the Voskhod 2M model. Since the early 90s, serial production of the Voskhod 3M 01 modification began. But still, many owners of this device are not satisfied with the appearance. Therefore, in this article we will talk about tuning sunrise 3m.

Transmission

During transmission repairs, the following work may be required:

Adjusting the clutch, replacing its disc and bearing;
Clutch drive repair;
Replacement of gearbox bearings;
Repair of switching module parts;
Restoration or replacement of gearbox gears.

Most of them require high qualifications and are difficult to do at home. The exception is the repair and replacement of drive mechanisms. So, sometimes there is a need to restore the splines for the gearbox foot, replace the clutch cable or its jacket, or adjust the clutch. These works are carried out without disassembling the crankcase.

Repair and operation of the Voskhod motorcycle are closely interconnected due to the age of the model. However, with the proper approach to organizing and carrying out repairs, the motorcycle will remain your faithful friend and assistant for a long time.

Supply system

To make the bike go faster, you need to adjust the original carburetor for a higher fuel supply or replace it with a more efficient one. To install a new carburetor, you need to perform the following steps:

we grind aluminum bushings under the flange of the pipe attaching the carburetor to the cylinders;
cut off the edge of the inlet channel;
take a flange from an old carburetor;
We fasten all the elements using cold welding.

The assembled carburetor must line up exactly with the intake port.

Engine and possible breakdowns

The Voskhod 3m engine is two-stroke, carburetor, single-cylinder. The working volume of the cylinder is no more than 173.7 cm3. Piston diameter/stroke – 62/57.6 mm. Engine power is 15 hp. A used engine in working condition can be purchased for 2000-4000 rubles.
