rag between the timing gears.
2. Tighten the nut of the right hand timing gear to a
torque setting of 35 in-lbs.
3. Loosen the nut of the left hand timing gear.
4. Place 0.003” shims in front and behind the tooth
of the left hand rotor. Once the shims are in place
and with the rotor movement still restricted
tighten the nut on the left hand timing gear to a
torque of 35 in-lbs ft-lbs.
5. Remove the shims and folded rag. Check to rotors
for correct clearance by rotating them. The rotors
should turn freely and not make contact at any
point, listen for sounds of the rotors touching.
