The nuts securing the inlet or outlet elbow of the air cleaner may loosen thus allowing
dust to be drawn into the engine. Check that the securing nuts are properly tightened
according to the following procedures.
(1) Tools required.
(a) 9/16 inch socket, 1/2 inch drive
(b) 6 in. socket extension, 1/2 inch drive
(c) Torque wrench, 1/2 inch drive, 0-175 ft-lb
(2) Whenever the air cleaner is serviced or replaced, check that the elbow securing
nuts are properly tightened.
On the M60 series tank, the nuts in positions and 2 of the
o u t l e t elbow cannot be tightened if the air cleaner is
mounted on the tank. Be sure to tighten all nuts whenever
the air cleaner is removed.

An improved spring-loaded filter element is available that has increased dust capacity.
This greater dust capacity provides greater mileage between cleanings. It also provides a
m o r e positive seal, t h r o u g h the use of spring loaded locking pins, that reduces the
possibility of dust ingestion.
