CJ750 Gearbox gets a new 3rd and 4th gear - Adjust the input shaft
05 October, 2024
The input shaft should have a 0.2mm clearance.
First start with the measurement from the bearing to the housing.
Take the measurement of the depth of the bearing reception.
The gasket is available in two different thicknesses, so make sure to measure it.
Now adjust the position of the bearing. Moving the bearing to the measured length can be challenging as the bearing does not slide but rather jump in steps. To solve this, place a gauge block with a feeler gauge of matching thickness between the bearing and the gear as a stop block. Adjust the gauge size for each measurement cycle to achieve precise positioning.
Check the measurement again and verify the play with the cover and gasket (dry) on.
The same for the output shaft to make sure the smaller back cover does not push against the bearing and also has a 0.2mm clearance.
