Install the camshaft between two centres and check for distortion using a dial gauge: service limit: 0.1 mm.
Note: The effective distortion will be half the total reading obtained on the dial gauge.
Each camshaft is stamped with an identification letter:
- O: horizontal;
- V: vertical.
Checking the oil seals
Fit new oil seals at each engine overhaul.
Insert the new oil seals squarely in their bores. Use suitable drifts.
Lubricate the lip of oil seals after assembly. This operation must be performed very carefully.
