Camshaft radial clearance, checking

Work sequence

- remove camshaft sprocket
- remove camshaft and cam followers (mark followers)
- remove oil seal
- clean camshaft bearing caps, seats and journals

- place camshaft on cylinder head so cam lobes do not touch valve spring retainers or valves
- lay Plastigage(R) across journal
- install bearing caps in correct position and tighten to 20 N-m (14 ft.lbs.)


CAUTION

Do not rotate camshaft..
- remove bearing caps
- compare width of Plastigage(R) with measuring scale wear limit - 0.1 mm (0.004 in.)

Note If this limit is exceeded, check the radial clearance again with a new camshaft.

If the clearance with a new camshaft also exceeds the wear limit, the cylinder head must be replaced, - after completing repairs, check and adjust valve clearances
