For the two-piece assembly there are three positions in which the seal can be fitted in the housing (A).
l Position "1" (A1) is used when a new seal is first fitted in service.
l Position "2" (A2) is used when a new seal is fitted in service and the crankshaft flange is worn in position "1".
l Position "3" (A3) can be used with a new seal in service, if a wet clutch is not used and the crankshaft is
new or the crankshaft palm area has been corrected. Ensure that the seal is fitted square in the housing.
If all positions have been used it is permissible to grind the crankshaft flange, refer to the Data and dimensions
for "Crankshaft" on page 20.
