Instructions for assembling and disassembling the IZH Jupiter 5 engine


Engine IZH Jupiter

In 1961, an Izhevsk motorcycle called Jupiter was released. A new family of IZH Jupiter has appeared. The design is similar to the IZH-56 motorcycle produced earlier. Its significant difference is the installation of a two-cylinder engine. In addition, some changes have been made to the clutch, gear shift device and electrical equipment. At the front of the crankcase there are two crank chambers, and at the rear there is a gearbox. The crank chambers are closed with covers and each of them contains crankshafts on ball bearings, which are protected from axial displacement by retaining rings. The crankshaft axle shafts are sealed with oil seals. Under the left crankcase cover mounted on a gasket, the front chain drive, clutch and trigger mechanism are located. The crankshafts are connected to each other by an external flywheel. The generator rotor and the breaker cam are installed on the axle cone of the right crankshaft. The generator housing is mounted on the crankcase. The engine pistons are connected to the crankshaft connecting rods using piston pins, which are protected from axial displacement by retaining rings. The engine cylinders have aluminum jackets and cast iron liners. The cylinder heads are made of aluminum alloy and are attached together with the cylinders to the crankcase with studs.

Engine part of IZH Jupiter

The motor part of the engine consists of a cylinder-piston group, a crank mechanism and a crankcase group.

Clutch IZ Jupiter

Located on the left side of the engine in an oil bath. Closed with a lid with a gasket to prevent oil leakage. The main thing that can be said when assembling the coupling. Some conditions need to be met. The first compression spring nuts should protrude 3.5 - 4.0 mm above the caps. This will save the disks from distortion. Tighten the second adjusting screw until it stops. Then loosen by 1/4. 1/2 turn. Essentially this is a clutch adjustment.

Gearbox IZH-Jupiter

The gearbox of the IZH-Jupiter motorcycle on the IZH-Yu motorcycle is the same as on the IZH-56 motorcycle and differs only in the design of the switching mechanism. Basic care is checking the oil and replacing it in a timely manner.
