Regrinding

NOTE: Ensure that all components are scrupulously clean, blow out all oil galleries in the crankcase, crankshaft and camshaft with clean, dry compressed air.


CRANKSHAFT REGRINDING

Early engines prior to engine numbers:
- 8L168437 RoW except
- 8L147650 UK and Europe

Regrinding of the crankshaft is generally recommended when wear or ovality in excess of 0.08 mm (0.003 in) is found. Grinding may be undertaken to a limit of 0.51 mm (0.020 in).

Grinding beyond the limit of 0.51 mm (0.020 in) is not recommended and in such circumstances a new crankshaft must be obtained.

Oversizes of journals are stamped in the adjacent web at the forward end of the crankshaft.

Later engines from engine numbers:
- 8L168437 RoW Except
- 8L147650 UK and Europe

Later engines have crankshafts that are specifically hardened and cannot be reground.
