HOSE AS 2687957 - Caterpillar

Torque Converter
Problem: Torque converter gets hot. Probable Cause:1. Low oil level in transfer gear case.2. Low water level in engine radiator.3. Restrictions in oil cooler or oil lines.4. Too much operation of machine at or near stall speed (overload).5. Too much oil in the converter housing around the converter because of: a. Too much oil leakage inside the converter.b. Ratio valve for the torque converter does not move (too much inlet oil).6. Not enough oil to the converter because of: a. Ratio valve for the torque converter does not move (not enough inlet oil).b. Oil pump failure.c. Too much leakage in transmission. Problem: High pressure at converter outlet relief valve tap. Probable Cause:1. Adjustment of converter outlet relief valve not correct.2. Valve spool in outlet relief valve does not move.NoSpin Differential
NoSpin Differential Test (Before Installation)
After the NoSpin differential has been assembled and before it is installed in the machine, make a test of the operation of the differential as follows:1. Install the NoSpin differential in the case.2. Put the case in a stand or a vise to keep it from rotation.3. Install both axles in the case.
Test Procedure For NoSpin Differential
(1) Case. (A) Axle. (B) Axle.4. Put a force in a clockwise direction on both axles.5. Keep the force on axle (A) and turn axle (B) in a counterclockwise direction. A small noise will be heard in the NoSpin differential and axle (B) will turn freely. Make sure the force is kept on axle (A).6. Keep the force on axle (A) and turn axle (B) in a clockwise direction. A small noise will be heard in the NoSpin differential and axle (B) will not turn any farther.
NoSpin Differential Test7. Put a force in a counterclockwise direction on both axles.8. Keep the force on axle (A) and turn axle (B) in a clockwise direction. A small noise will be heard in the NoSpin differential and axle (B) will turn freely. Make sure the force is kept on axle (A).9. Keep the force on axle (A) and turn axle (B) in a counterclockwise direction. A small noise will be heard in the NoSpin differential and axle (B) will not turn any farther.10. Do Steps 4 through 9 again, except now hold axle (B) and turn axle (A).If the NoSpin differential does not have the correct action, inspect the components and check the assembly procedure.
