3b. The shimming procedure is as follows:
Fit tool 87 90 552 into the gearcase as shown in the figure, and use feeler gauges to measure the distance between the tool and nut. Fit shims
corresponding to the thickness of the feeler gauges.
4. Use sleeve 83 90 148 to fit the reverse gearwheel.
5. Fit 1st gearwheel onto the reverse gear bearing sleeve.
6. Fit 1st / 2nd gear synchromesh hub. Fit 1st / 2nd selector fork to 1st / 2nd synchromesh sleeve and fit the assembly onto the synchromesh hub.
7. Use tool 83 90 148 to fit the sleeve for 2nd gearwheel and fit 2nd gearwheel onto the sleeve.
8. Use tool 83 90 148 to fit the sleeve for 3rd gearwheel and fit 3rd gearwheel onto its sleeve.
NOTE: A number of 3rd gearwheels of gearboxes between the following serial numbers GM 108 967 - 109 854 and GM 111 501-112 832 are
fitted with two circlips as a result of a dimensional error. The error does not affect the performance or strength. The two circlips are fitted so that
the 3rd guide ring will not come into contact with the layshaft pinion.
