Final Drive Type BB - Installation Instructions
THIS UNIT WILL BE DAMAGED IF IT IS INSTALLED INCORRECTLY. PLEASE TAKE CARE WHEN INSTALLING THE HYDRAULIC LINES.
Attaching the hydraulic lines incorrectly will immediately damage this unit and will cause both hydraulic and mechanical failure. Please take care in installing the correct lines to the correct ports.
- Make sure any system contamination from a prior failure has been addressed.
- Remove dirt and debris from the track frame and hoses/pipes to prevent accidental contamination.
A – B PORTS:
Located in the center of the flange these are the inlet and outlet ports. These will be the two larger diameter hoses. Transfer adapters from previous drive and complete hose connections.
C1 – C2 Ports:
The drain ports are located to the right and left of the A/B ports. The position of the drain port can be changed by placing a plug in either C1 or C2. It’s important to always attach the case drain hose to the uppermost port so any air can escape the case and leave the bottom port plugged. Transfer adapter from previous drive and complete connection.
The two speed port is centered above the A/B ports. Transfer adapter from previous drive and complete connection.
After Installation: Before operating machine check the gearbox oil level and top off with SAE 80W/90 gear oil if necessary.
Tip: Don’t run a replacement final drive unless you are certain you understand the reason for the original failure—and have rectified the fault.
