REMOVING GEAR
(Typical Example)
A. 1P2321 Puller. B. 8S5579 Spacer. C. 98S9155
Spacer.
To install the gear use the following procedure:
1.
Heat the gear to a temperature of approximately
400°F (204°C) 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 600°F (315°C) 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 completely
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 Nm). 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 (1) 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.
