Towing Procedure

CM063510004-UN-18OCT05

Ground drive piston pump ports

A - Port A

B - Port B

1. A loop (free flowing circuit) in the ground drive system must be created to allow oil to flow without restriction through the ground drive motors.

   • Double pump transmission (track and wheel types)
   
   

   Two connections (dash size 16 male-male) are required to join hoses from ports A and B of the two ground drive piston pumps. together First, take the left-hand ground drive motor hoses from ports A and B of the independent piston pump and join them together using one connection. Use the other connection to join the right-hand ground drive motor hoses together from ports A and B of the independent piston pump. Cap any fittings in order to prevent contamination of the hydraulic system.

2. The disk brakes located in each final drive must be pressurized in order for them to be hydraulically released.

3. Connect the two brake lines, located on the back of each final drive, to the manual hydraulic pump using a T fitting. The manual hydraulic pump is used to pressurize the disk brakes so they can perform the hydraulic release.

4. A pressure of 20 bar (300 PSI) must be maintained during the tow in order for brakes to remain free.

5. Tie down and secure all loose hoses.

   NOTE: In cases of urgency where the adequate resources for the procedures cited above do not exist, the front part of the final drive can be opened ( Cover - releasing allen screws with a 6 mm screwdriver) and remove the first gearing assembly. This will free the machine to be towed a few meters. This first gearing assembly comes out by hand and with it all the drive oil, allowing the machine to be moved a few meters.
