Reply To: Crankshaft end float mystery

[Philippe AllisonParticipant]

Maybe I have not explained very well. The sprocket thickness is irrelevant. When I set up the end float I have a tube that I use to replace the sprocket that is an easy slide fit on the crank, this saves the bother of trying to remove the sprocket in between each trial fitting.

The shims are the first pieces to slide onto the crankshaft and they space the thrust washer away from the main bearing caps, they effectively make the journal longer.

So:

1.       Fit crankshaft ensuring the thrust faces are flush, torque down and check free rotation.

2.       Slide shims onto the crank.

3.       Fit thrust washer, sprocket (no woodruff key at this stage)

4.       Tighten nut to correct torque.

5.       Measure end float.

6.       Add or remove shims to achieve correct end float.

7.       Re-assemble with timing chain and woodruff key.

8.       Tighten to correct torque.
