C. Converter inlet (P3).
D. Converter outlet.
When tests and adjustments are made to the torque converter, the parking brake must be OFF. To prevent movement of the machine and personal injury do the procedure that follows.
1. Lower the bucket to the ground.2. Put blocks in front of and behind the wheels.3. Install the anti-pivot link.4. Let only approved personnel on the machine and keep other personnel off of the machine and in clear view of the operator. All tests and adjustments must be made with the oil in the hydraulic control system at normal temperature of operation. Be sure the linkage adjustments are correct before tests are made.
