Fairfield W2B Axle Service Manual

The W2B is a Torque-Hub final drive, the planetary wheel end that turns axle input into drive torque at the wheel. It's used on Franna machines. When the hub leaks, rolls rough, or makes noise, someone has to pull it, rebuild it and prove it's right before it goes back on the machine. That's who reaches for this manual.

What this manual helps you do

• Follow the disassembly procedures to strip the hub down in the right order.
• Rebuild each sub-assembly using the sub-assembly procedures, then close it up with the main assembly procedure.
• Set bolt tightening and torquing the way the manual lays it out, so fasteners go back correctly.
• Verify the finished unit with the roll and leak testing procedures before it returns to service.
• Check the cross-sectional view and parts list to identify what sits where inside the unit.

Who this is for

Independent repair shops, rental fleet mechanics and crane service technicians who are rebuilding a W2B final drive in-house. It also suits plant maintenance staff working on a Franna machine that arrived with no paperwork.
