REMOVING GEAR
(Typical Example)
A. 1P2321 Puller. B. 8S5579 Spacer. C. 9S9155
Spacer.
To install the gear use the following procedure:
1. Heat the gear to a temperature of approximately
400°F (2041C) before installing on the camshaft.
CAUTION
Do not heat the gear with a torch. Do not
heat the gear to a temperature of more than
600°F (315°C). Heating the gear with a torch
or to a temperature of more than 600F
(3150C) may cause the two drive dowels for
the automatic timing advance to loosen and
come out of the gear.
2. Align slot in gear hub with the pin in the camshaft.
Install the gear on the camshaft with timing mark on
gear aligned with timing mark on crankshaft gear.
Be sure the gear is completly seated against the
shoulder of the camshaft.
CAUTION
Do not drive the gear on the camshaft.
3. Align holes in weights with dowels in gear and install
the automatic timing advance.
4. Align pin (3) in washer with hole (4) in camshaft and
install washer (2).
5. Install screw (1) and tighten to 72 + 5 lb. in. (8.2
0.6 N m). Stake screw in two places.
INSTALLING WASHER
2. Washer. 3. Pin. 4. Hole.
CAUTION
Stake screw (1) carefully. Heavy blows on
washer or screw can force the shaft
extension too far into the camshaft and
eliminate all end clearance.
6. After screw (I) is staked, the gear and weight
assembly requires end clearance to prevent binding
against the washer, camshaft end or camshaft gear.
The required end clearance is .003 to .037 in. (0.08
to 0.84 mm).
STAKING SCREW
1. Screw.
