MEASURING DISTANCE "Z"
BETWEEN INPUT SHAFT AND PlNlON SHAF'I
Since the new Porsche synchronizing system does not employ circlips, ir is important to make sure
that distance "2" is maintained between end face of inpur shaft and 4rh/5rh speed hub on pinion shaft,
Dirrance "Z"
0.2 to 0.3 mm up to transm. no. 118 1092
0.4 to 0. 6 mm from rransm. no. 118 lo!13
1. Measure distance '7" between input shaft and Note
hub with a feeler gage.
Do not measure distance between synchronizer
ring and shift sleeve or clutch body and shift
sleeve.
2. If distance "2" is nor 0. 2 IO 0. 3 mm or
0.4 to 0. 6 mm. disassemble pinion shaft
again and correcI shim thickness "X". Of
course, it will also be necessary to redeter-
mine shim thickness '7'" on end of pinion
shaft.
