SHEAR PIN
SPROCKET
Grease fitting located on hub of shear pin sprocket.
Check safety collar. Check for loose setscrews or
loose key. Check teeth for wear. Replace when tooth
wear presents an observable hooked profile.
M
Remove chain and shear pin. Rotate hub to expose
shear faces. Clean faces and swab with Lithium based
#2 grease. Reassemble pin and chain.
SA
CAUTION: When reinstalling shear pin, necked
down portion must be aligned in the shear plane.
FINAL DRIVE
ASSEMBLY
Check oil level at sight gauge located under floor
plate cover. Final gear/oil condensate drain is the
1-1/2" (38 mm) ball valve located below sight gauge.
Pinion oil/condensate drain is the 3/8" (10 mm) ball
valve located at the pinion bearing hub. NOTE:
Condensate can accumulate at all drain points,
therefore, both final gear and pinion drains must be
checked.
D*
If low, check for leaks in oil or condensate drain
piping and final drive housing. Add oil to proper
level.**
If high, check for evidence of condensate (water)
in oil. Drain small amount of oil through the oil
and condensate drain valves and inspect. If clear
water is present, drain until oil is draining. Refill
to sight gauge with proper grade of oil.** Check
for loose or damaged dust shield.
*Or after severe weather or wash-down procedures.
**Due to the viscosity of the oil, it can take several hours for a true reading to occur at
the sight gauge. Overfilling of oil will result in oil leaking into the collector.
