3-7.2 Asbestos Dust During Clutch Servicing
Excessive amounts of asbestos dust may be a potential health hazard that may cause serious injury or possibly
Because studies have indicated that exposure to excessive amounts of asbestos dust may be a potential health
hazard, the Occupational Safety and Health Administration (OSHA) has set maximum limits of levels of airborne
asbestos dust to which workers may be exposed. Since most automotive friction materials normally contain a
sizeable amount of asbestos, it is important that people who handle clutch linings be aware of the problem and
know the precautions to be taken.
Areas where clutch work is done should be set aside, if possible, and should be posted with an asbestos exposure
sign as follows:
ASBESTOS DUST HAZARD
AVOID BREATHING DUST
WEAR ASSIGNED PROTECTIVE EQUIPMENT
DO NOT REMAIN IN AREA UNLESS YOUR
WORK REQUIRES IT
BREATHING ASBESTOS DUST MAY BE
HAZARDOUS TO YOUR HEALTH
OSHA standards should be consulted with respect to mandatory requirements as well as for suggested
procedures to minimize exposure. (Reference: Title 29, Code of Federal Regulations, Section 1910.1001.)
3-8.1 Periodically inspect electrical connectors on the outside of the cab, on the engine and frame for corrosion and
tightness. Exposed terminals such as water temperature, oil pressure, fuel sender, cranking motor and feed through studs
should be cleaned and recoated with a suitable grease such as IH 472141-C1 or equivalent. This should include ground
cable connections for batteries, engine and cab.
For effective emission control and low operating cost, it is important that maintenance operations listed on the
following pages be performed at the specified periods or mileage intervals indicated (kilometers, miles, hours or
months, whichever occurs first).
Service intervals are based upon average operating conditions. Where dusty, frequent start and stop or heavily
laden operations are encountered, more frequent servicing will be required.
