REMOVAL
WARNING
Use extreme caution when handling heavy parts. Transmission weighs approximately 1,654 lb
(750 kg). Provide adequate support and use assistance during procedure. Ensure that any lifting
device used is in good condition and of suitable load capacity. Keep clear of heavy parts supported
only by lifting device. Failure to follow this warning may result in death or injury to personnel.
Improper use of lifting equipment and improper attachment of cable or chains to vehicle can
result in serious personnel injury and equipment damage. Observe all standard rules of safety.
Hydraulic fluid is very slippery. Immediately wipe up any spills. Failure to follow this warning
may result in injury to personnel.
CAUTION
If engine and/or transmission is not operational and boom must be elevated, auxiliary pump can
be used to provide hydraulic power for boom operation. Operate pump for not more than four
minutes and allow pump to cool for not less than two minutes. Perform operate and cool cycle as
many times as needed to elevate boom. Failure to allow pump to cool may cause damage to pump.
DO NOT begin transmission assembly replacement without first having all required tools and
equipment to complete the procedure. This will help in reducing the time boom must remain at
maximum elevation.
Wipe area clean around all hydraulic connections prior to disconnecting. Cap or plug all openings
after disconnecting. Contamination of hydraulic system could result in equipment failure.
NOTE
Ensure all hydraulic hoses, lines, fittings, and electrical wiring harnesses and leads are tagged for
identification and location prior to disconnection.
When disconnecting hydraulic lines or hoses, position suitable container to catch hydraulic oil
retained in lines and hoses.
