NOTE: Before reinstalling cam support plate, replace oil pump
scavenge o-ring (supplied in kit) even if the original appears to be in
good condition. The stock o-ring can become brittle and provide a poor
seal if reused.

If resistance is encountered, determine cause and correct problem before
proceeding. Do not force support plate into position!

NOTES:
Crankshaft and cam drive gears have a light press t on their respective
shafts. Start gears squarely on their shafts and use their mounting bolts
to pull them all the way into position.
Make sure that no metal burrs are raised when installing the gear sets.
Burrs can form underneath the gear causing excessive gear run out.

Too much backlash can cause excessive gear noise or clicking
caused by the reversing of the forces applied by the lifters to the
cam lobes. Insucient backlash, will cause gears to whine, wear
prematurely, create excess heat, and may cause breaking of the
gear teeth and engine failure
NOTE: The rear cam drive gear is slightly larger than the stock drive
sprocket and needs to be checked for interference with cam cover before
proceeding.
