GBA20 layshaft with Power Shuttle
G . Shimming the shaft
IMPORTANT: To carry out shimming on the mainshaft,
the new unit must be refitted (see chapter 5).
35. Carry out the shimming on the shaft to obtain
clearance of J2 = 0 to 0.08 mm (Fig. 6)
36. Install the locally made tool (Fig. 7 and § I) in the
shaft.
37. Slightly compress the spring, while tightening the
nut of the tool, to correctly seat the bearing cones
in their cups.
38. Rotate the shaft a few turns. Check spring
compression again.
39. Using a depth gauge (Fig. 5), measure dimension X
between side A of bearing cup (52) and side B of
the housing (Fig. 6).
40. Measure thickness Y of oil deflector (50).
41. Calculate the difference between X and Y.
42. Determine the thickness of shims required to
obtain J2.
N
OTE: If possible, shim so as to obtain minimum
tolerance.
43. Remove the compression tool.
44. Fit shims (51) selected in operation 42.
45. Fit the oil deflector in the housing.
