Tadano RF80C-76F4 and RF80M-77J0 Transmission Service Manual

A torque converter and transmission sits between the engine and the drive line on a crane like the RF80C-76F4 or RF80M-77J0. It takes engine power, multiplies torque at low speed and passes it through the gear sets to the wheels. When it slips, runs hot or shifts badly, the crane is parked. A fleet mechanic or independent shop reaches for the service manual to find the fault and fix it in-house instead of waiting on an outside rebuild.

What this manual helps you do

• Diagnose shift and drive complaints using the troubleshooting section.
• Follow the disassembly and reassembly sequence when you pull the unit apart on the bench.
• Check wear limits against the maintenance standards before you decide to reuse or replace a part.
• Verify the unit after a rebuild by running through the test section.
• Review the oil section for fluid requirements, and read the structure and function sections to understand how the clutches, shafts and gear sets work together.

Who this is for

A rental fleet mechanic or crane service technician who is repairing a transmission on one of these Tadano models without dealer support. It also suits an independent repair shop that takes in these cranes and needs the workshop procedures on hand.
