Transmission

Manual box of gear shifting (RKPP)

General information

In the present Chapter the such are considered components of the transmission line of the car, as a transmission (manual (RKPP) and automatic, considered together with the converter of rotation and called below automatic transmission (AT)), a transfer case and driveshafts. Assembly of coupling of the models equipped with RKPP, is considered separately.

Models of 4.2 l

On carburetor models of 4.2 l RKPP FS5R50А with five forward transfers and one back is established, all from which (including back) are synchronized.

All conducted gear wheels are kosozuby and are in continuous gearing with gear wheels of an intermediate shaft. Gear wheels of the first, second, third and back transfers are established on roller bearings on conducted to a shaft. The gear wheel also on the roller bearing is established by a transfer heel on intermediate to a shaft. The intermediate gear wheel of a reverse gear is established on separate to a shaft by means of roller bearings.

In a forward part of an intermediate shaft for the purpose of minimization of a dead course of the block of gear wheels the podpruzhinenny gear ring is established.

Gear shifting is made at the expense of a gear wheel joint with synchronizer assembly by introduction internal шлицов synchronizer couplings in gearing with a teeth of the synchronizer of the corresponding transfer. Synchronization is reached when the ring of the synchronizer contacts with a cone on a gear wheel wall that forces to rotate a gear wheel with synchronizer assembly in identical in the speed, providing smoothness of switching.

Primary shaft rotates in the ball-bearing located in a forward part of a transmission and comprises the roller bearing into which the forward pin of a conducted shaft enters. The back part of primary shaft leans on two ball-bearings one of which is located in a box case, and the second - in a lengthening casing.
On the left wall of a case of transmission the demountable cover serving for removal/installation of the block of selection of capacity (RTO) is fixed.

On models of 4.2 l of EFI of late years of release the modified transmission of FS5R50А with the changed transfer relations (see size tables and adjustments at the end of the Management) is used. Here the quantity of a teeth of a leading gear wheel of primary shaft is increased to 27, and a conducted gear wheel of an intermediate shaft - is reduced to 34. The first and third transfers are equipped with synchronizers with double blocking rings.

Models of 3.0 l

On model of 3.0 l completely synchronized RKPP FS5R30А with five forward transfers and one back is established also.

Gear wheels of forward transfers are kosozuby and are in continuous gearing with group of gear wheels of an intermediate shaft. Gear wheels of the first, second and third transfers on roller bearings are planted on a conducted shaft of a box, the gear wheel also on the roller bearing is established by a transfer heel on an intermediate shaft. The intermediate gear wheel of a reverse gear is located on separate to a shaft and supplied with two roller bearings.

Synchronization at gear shifting is reached also as well as in boxes of FS5R50А of models of 4.2 l.
Primary shaft rotates in the ball-bearing located in a forward part of a transmission and comprises the roller bearing into which the forward pin of a conducted shaft enters.

The conducted shaft rotates with the bearings located in a bearing plate and a casing of lengthening whereas bearings of an intermediate shaft are in a case of coupling and a bearing plate.
