15.6 Crankshaft pulley removal

1. Install two safety bars (M12 x 1.25) into the
threaded holes in the rear end of the crankshaft.
Put a bar between the safety bars to hold the
crankshaft to prevent it from rotating.
2. Remove the crankshaft pulley.
WARNING
When removing the crankshaft pulley, be prepared to
stop the job in case the bar slips off the crankshaft to
prevent injury.

position and remove the case.
CAUTION
The front plate is bolted inside the timing gear case.
Do not attempt to remove this plate along with the
timing gear case by tapping.
