At installation it is necessary to use new самоконтрящиеся nuts.
After removal of fasteners, installation them needs to be carried out on the same places and in the same situation. If the fastener needs to be replaced, it is necessary to use the original fastener or an element of the same size and characteristics.

At installation it is necessary to use new fasteners on which carving the blocking structure interfering their otvorachivaniye is applied. Tightening of fasteners needs to be carried out only by the recommended inhaling moments.

General information

Power shafts transfer torque from the engine, the transmission and differential to forward wheels. In a transmission case power shafts fasten shlitsevy connections with semi-axial gear wheels of differential. Fixing of a shlitsevy tip of the internal hinge of a power shaft in a semi-axial gear wheel is made by a spring lock ring. At installation the lock ring contracts, entering a shaft flute. After the shaft is completely established in a semi-axial gear wheel of differential, the lock ring is unclenched and fixes shlitsevy a tip from axial movement. External hinges of power shafts fasten to the naves of forward wheels established on bearings. Fastening of a shaft to a nave is carried out by a nut with a fillet. For a nut otvorachivaniye exception the fillet of a nut is bent in dredging of a power shaft.

Hinges of equal angular speeds (CV JOINTS) are installed from two parties of a power shaft. All external CV JOINTS – the Birfield type, and internal – tripoidny or ball type. CV JOINTS of tripoidny type are used for prevention of transfer of vibrations of the engine through power shafts on a car body. CV JOINTS are necessary for torque transmission and compensation of the movement of a forward suspension bracket. Also, CV JOINTS allow to change length of a power shaft and to transfer torque under constantly changing corners.
