CAUTION
Positioning of camshaft bushing in No. 7 bushing bore (rear of
cylinder block) is important. The new bushing must be pressed in
leaving clearance between bushing and rear face of cylinder block
to allow oil to drain from hole at rear of camshaft. Hydraulic lock
will occur if oil drain passage is blocked.
NOTE
No. 1 cam bushing is wider, all others are the same.
1. Using cam bushing replacer, press seven camshaft bushings (1) into camshaft bore (3) alining oil
holes (4) in camshaft bushings (1) to oil holes (2) in camshaft bore (3).
2. Using welding rod, ensure oil holes (2) and (4) aline. If welding rod does not pass through oil holes,
reposition camshaft bushing(s) (1).
CAUTION
Use extreme care when installing camshaft. Failure to do so may
result in damage to camshaft lobes and bearings.
NOTE
Assistant will help with step 3.
3. Apply lubricating oil to camshaft (6) and camshaft gear (7) and install camshaft (6) and camshaft
gear (7) in cylinder block (5).
4. Aline index mark on camshaft gear (7) with index mark on crankshaft gear (8).
