7. Measure the shim thickness between the clamp
ring and the gear housing as follows:
Hold the double bearing box as indicated in the picture
with its calculated number of shims (see point 16,

NOTE! The guide pin! Add a sufficient number of
shims to the clamp ring to obtain a clearance of max.
0.10 mm (0.004") between the clamp ring and the
gear housing. Push the clamp ring into its position by
hand and use a feeler gauge and measure the clear-
ance all around.

Press the new sealing ring against the collar in the
double bearing box, with the open part against the
bearing. Use special tools 9991801 and 884312.

groove of the recessed washer. Use grease to get at-
tachment.
