Input shaft repair

The input shaft is a block of drive gears, one part of which is made on the shaft, and the other is pressed with a large interference fit. Therefore, the input shaft is a non-separable structure, only bearings can be replaced.

Troubleshooting the input shaft, its gears and bearings is similar to troubleshooting the output shaft (see «Secondary shaft repair»).

You will need: universal puller, hammer, mandrel.



To replace the rear bearing 3, press it with a puller and press the new bearing up to the stop with the help of an appropriate mandrel, applying force only to the inner race of the bearing. When replacing the front bearing, pay attention to the fact that a thrust ring 2 is installed on the shaft under its inner ring 1.
