BELT PULLEY (OLD STYLE)

Removal

Remove the four capscrews attaching the

pulley assembly to the clutch housing. Re-

move the cap from pinion shaft and remove

the bearing adjusting nut and pull pulley hub.

Remove the caps from the bevel gear shaft

bearings. Move gear away from pinion as

far as possible. Place two solid blocks be-

tween gear and case on pinion side of gear.

Press shaft from gear. Pull pinion from

case. Remove oil seal and bearing cups. It

will not be necessary to remove the snap

rings.

Inspection

Check the bearings for wear, rough or chipped

rollers. Check gear teeth for wear or chip-

Assembly

Install the pinion in case and the oil seal

with lip towards pinion end of shaft. Adjust

bearings to a free rolling fit without end

play or binding. Lock the bearing adjusting

nut by punching a section of the thin flange

into the shaft keyway. Install the seal cap

tainers. Adjust bearings to a free rolling fit

without end play or binding, by use of shims

between retainers and case. Adjust gear

backlash to .004" to .007" by removing shim

from one retainer and installing under oppo-

site retainer. This method will maintain

correct bearing adjustment while securing

correct backlash.

Use the gasket provided, which is hard paper

.010" thick between pulley and clutch housing.

If a single gasket does not give a gear back-

lash of .004" to .007" as required, use addi-

tional gaskets.
