Installation
Step 1
Clean all components of any preserves or deposits.
Step 2
Remove the timing cover.
Step 3
Hand turn crank to top dead center of cylinder #1. This
should line up the timing marks of the cam and crank gears
or sprockets. The timing mark on the cam gear should be at
6 o’clock and the crank mark should be at 12 o’clock.
Step 4
Remove the old timing set.
Step 5
Clean from the mounting surface of the block any deposits
left over from the gasket. Do the same for the timing cover.
Step 6
Using a small dab of grease install the bronze ring onto the
back of the cam gear.
Step 7
With the # 1 cylinder still at top dead center install both the
cam and crank gears. The chamfered side of the crank gear
faces the crank.
Step 8
For GM and Mopar install desired off set bushing on the
cam dowel pin. If the cam is not being degreed inset the 0°
bushing (bushing with hole right in the middle).
Ford cam gears do not require offset bushings. Line up your
desired timing as it is marked on the cam gear. Part #’s
0130201, 0130202, 0135102 are marked with advanced (A),
retarded (R), & standard (0), part # 0146001 is marked with
+4, +8, & 0.
Step 9
With the lock plate in place on the cam gear, torque the cam
bolts with washers to factory specs.
Step 10
Bend the tabs of the lock plates over the heads of the bolts.
Step 11
Slide the idler gear into place with the larger gear on the left
and the long part of the idler axle facing the block. The
smaller gear should have free vertical movement of 0.005”-
0.075” when the idler gears are with both the cam and crank
gears. Turn the crank two full revolutions to insure the
clearance. Abnormal wear or damage will occur if the
smaller gear does not have enough running clearance.
Step 12
During operation the idler axles are always in contact with
the front timing cover. All clearance should be between the
block and the idler axle. To check for clearance install the
idler gear about half way. Then install the cover with the
gasket and push the cover into place. Hand-tighten the
cover bolts then remove the cover. This will show you
where the idle gear will sit. If the clearance is not sufficient,
0.005” minimum, grind off from the axle if necessary.
Step 13
Install the cam thrust bearing in the cam gear. Solid side
facing out.
Step 14
Check for clearance between the cam thrust and the front
timing cover. There should be between 0.005-0.010” of
clearance. An easy way to check the clearance is by putting
clay on the end of the cam thrust bearing. Install the cover
with the gasket on and hand-tighten. Then remove the cover
and check the putty. If clearance is needed grind the required
endplay off of the cam thrust bearing.
Step 15
After all clearances are met install the timing cover with a
sealant along the gasket. Torque the timing cover bolts to
OEM specs.
