Torque Talk
Nuts on the scraper’s front wheels take different torques.
Too much torque on the
planetary gear cover will
put the squeeze on the O-
ring underneath. Then the
cover will let oil leak.
Low or no oil means the
bearings will burn out.
You won’t find torque
values in the TM, so
torque carrier cover stud
nuts to 235-295 lb-ft and
planetary gear cover nuts
to 65-86 lb-ft.
Tire PSI Reminder
Check the scraper’s tire pressure before operation. Front tires get 60 psi and
rear tires get 40 psi.
Low air pressure in front tires may cause ‘em to slip on the rim, overheat
and blow out. Or it could cause the tire-to-rim seal to break and lead to a flat
tire.
When you have a flat front
tire, you may lose the driver,
that little piece of metal that
ties together the final drive and
the side ring. Without it, there’s
no way to deliver power to the
wheel.
Replace lost drivers with
