Transmission

Manual box of a gear change (Manual transmission)

general information

In this chapter we are considered components of the transmission lines of the car as the gearbox (manual (Manual) and automatic , considered in conjunction with the rotation of the transducer below and called automatic transmission (AT)), transfer case and drive shafts . Assembling the clutch equipped models Manual transmission, considered separately.

Models 4.2 l

On carburettor models 4.2 l set FS5R50A Manual transmission with five forward gears and one reverse, all of which (including the back) are synchronized.

All of the driven gears are helical and are in constant mesh with countershaft gears. The gears of the first, second, third and rear gears are mounted on roller bearings on the driven shaft. Fifth gear and a roller bearing mounted on the intermediate shaft. An intermediate gear wheel transmission mounted on a separate shaft by roller bearings.

In front of the intermediate shaft to minimize gear backlash unit installed sprung toothed ring.

Gear shifting is performed by a joint assembly with gear synchronizer by introducing internal splines synchronizer clutch engages with the teeth of the synchronizer appropriate transfer. Synchronization is achieved when the synchronizer ring is brought into contact with the cone on the side gears, which forces the gear to rotate with the assembly of the synchronizer in the same speed, ensuring the smooth switching.

Input shaft rotates in a ball bearing located in front of the gearbox and includes a roller bearing, which includes a front pin of the driven shaft. The rear portion of the primary shaft is supported by two ball bearings, one of which is disposed in said housing box and the second - in the housing extension.
On the left wall of the transmission housing fixed removable cover that serves to remove / install the unit PTO (PTO).

On models 4.2 liter EFI late years of release a modified transmission FS5R50A with modified gear ratios (see. Table sizes and adjustments in the end of this manual). Here, the number of teeth of the pinion input shaft is increased to 27, and the driven gear of the intermediate shaft - reduced to 34. The first and third synchromesh transmission equipped with double locking rings.

L models 3.0

On l models 3.0 is installed as a fully synchronized Manual transmission FS5R30A with five forward gears and one reverse.

The gears of forward gears are helical and are constantly meshed with countershaft gear group. The gears of the first, second and third gears on roller bearings planted on the output shaft of the box, fifth gear and ball bearing mounted on the intermediate shaft. The intermediate reverse gear on a separate shaft, and is provided with two roller bearings.

Synchronization is achieved during gear changes as well as in boxes FS5R50A 4.2 liter models.
Input shaft rotates in a ball bearing located in front of the gearbox and includes a roller bearing, which includes a front pin of the driven shaft.

The output shaft rotates with bearings arranged in the carrier plate and the housing extension, while the intermediate shaft bearings are in the clutch housing and the carrier plate.
