Assembling input shaft

After dismantling the shaft, check the technical condition of its parts:

- On the gears are not allowed damage or wear of the teeth;

- At the ends of the teeth synchronizer ring should not be a significant crushing or chipping. Spot contact gear teeth should occupy the entire working surface of the tooth; gear bearing surfaces must not have any trace of wear and seizure;

- Coupling hub synchronizer should have no damage or jam, especially on the surfaces of the sliding sleeve; when it detects signs of wear on the ends of the teeth of the clutch needs to be replaced;

- On the surfaces of balls and rollers, as well as treadmills rings should not be damaged; the needle and the needle bearing cage must not have any trace of wear or damage.

Oil the shaft and replace the needle bearing idler reverse gear. Replace the idler reverse gear, in line with its conical part toward the end of the primary shaft.

Replace synchronizer ring.

Put the shaft synchronizer hub V transmission. Install the shaft under a press and slowly press them on the hub shaft; at the same time make sure that the splines of the locking ring placed against the lock crackers. Install the thrust washer V synchro transmission. Install the cover and press them bearing the bearing of a primary shaft (Fig. 4.22). Install the snap ring and measure the axial movement of the primary shaft, which should not be more than 0.1 mm.

With an increase in the gap using a lock ring of greater thickness.
