Minor concentrations of acetic acid vapor may be produced during application of silicone gasket material.
Adequate ventilation should be provided when silicone is applied in confined areas. Further, eye contact
may cause irritation; if eye contact takes place, flush eyes with water for 15 minutes and have eyes
examined by a doctor.
When using alkali cleaners, avoid skin contact or inhalation. Skin rashes and toxic effects may result.
When using solvent-type cleaners, avoid skin contact, inhalation, or conditions that may cause fire
hazards.
Particles blown by compressed air are hazardous. Make certain air stream is directed away from you and
other personnel in the area.
Compressed air used for cleaning purposes will not exceed 30 psi, use only with effective chip guarding
and personal protective equipment (goggles/shield, gloves, etc.).
During normal operation, the turbocharger and outlet pipe can become very hot. Be careful not to touch
these components with your bare hands. These components may be hot enough to cause severe burns.
Some tests require the ratio selector lever to be moved from the neutral position. Before any of the trans-
mission operation tests are made disconnect the truck drive shaft from the yoke of the transmission,
refer to TM 9-2320-273-20.
Diaphragm is spring loaded. Cage chamber while removing nut or injury might result.
Do not attempt disassembly or knuckle repair with the vehicle supported by jacks only. Severe injury can
result from an inadequately supported vehicle.
The spring brake air chamber employs a spring with high forces and extreme care should be used to ser-
vice this air chamber only as outlined in the procedure. Deviating from the procedure may result in
injury as a result of the high spring force.
DO NOT ATTEMPT DISASSEMBLY UNTIL YOU HAVE
READ AND UNDERSTAND THE FOLLOWING INSTRUCTIONS. DO NOT uncage the compression
spring with the spring brake chamber removed from the assembly as the spring free length is greater than
the release stud length. If service of the spring brake housing, compression spring, or pressure plate is
required, replace with a spring brake assembly.
Exercise care to avoid skin rashes, fire hazards, and inhalation of vapors when using SD-2 solvent-type
cleaners.
Do not use a cutting torch to remove the equalizer beam center bushings or end bushings. All equalizer
beams are heat treated for strength and long service life. The use of heat could adversely effect the
strength of the equalizer beams.
The weight of the vehicle must be supported by overhead hoisting equipment, floor jacks, or support
stands at all times. Do not attempt to support the weight of the vehicle on a hydraulic jack.
