Grease Zerks
Lubricate all zerks per instructions in manual

and area around them before servicing].
Front Idler/Rear Drive
Your Crawler is pre-lubricated at the factory for
the first 25 to 50 hours of operation [25 hours
for dusty, gritty conditions; 50 hours for normal
conditions]. After that period you may use one
of the following lubrication procedures:
Normal Conditions
: Clean area around each
"zerk" in Front Idler and Rear Drive
Assemblies. Remove zerks...try to have them
on the "top-side". Using an oil can with SAE
30 motor oil, fill each reservoir through
threaded hole...do this at day's end to allow oil
to soak into the bearings. Repeat oiling next
morning and replace zerks. Repeat process
every 25 hours.
Dusty Conditions
: Clean area around each
"zerk" on Front Idler and Rear Drive
Assemblies. Grease each zerk until you see,
or feel, grease coming out the bearing ends.
Track Tension
Maintain 4.5" overall length of #234 Spring on
each Track.
Check Service section of this Manual for
complete explanation and Track Tensioning
procedures.
Drive Chain Tension

final drive. Check Service section of this

Fittings & Hoses
Check hydraulic fittings and hydraulic hoses
for cracks, breaks, and leaks.

i m m e d i a t e l y. Contact factory with any
questions or requests for help.
