Initial/Back Flush

Initial Flush




1. Turn the J 35944-A water supply valve (1) to the ON position and allow water to flow through the oil cooler and pipes for 10 seconds to remove any remaining transmission fluid. If water does not flow through the oil cooler and pipes, the cause of the blockage must be diagnosed and the plugged component must be repaired or replaced. Continue with the cooler flushing and flow check procedure once the blockage is corrected.

2. Turn the J 35944-A water supply valve (1) to the OFF position and clip the discharge hose (5) onto a five gallon (19 L) pail with a lid, to avoid splashback.

3. Turn the J 35944-A water supply valve (1) to the ON position and depress the trigger (8) to mix cooler flushing solution into the water flow. Use the clip provided on the handle to hold the trigger (8) down. The discharge will foam vigorously when the solution is introduced into the water stream.

Important:
Flushing for approximately 2 minutes in each cooler line direction will result in a total of about 8 to 10 gallons of waste fluid. This mixture of water and flushing fluid is to be captured in a five-gallon bucket or similar container.

4. Flush the oil cooler and pipes with water and solution for two minutes. During this flush, attach the shop air supply 825 kPa (120 psi) to the flushing system feed air valve (2) located on the J 35944-A for 3 to 5 seconds at the end of every 15-20 second interval to create a surging action.

5. Release the trigger (8) and turn the J 35944-A water supply valve (1) to the OFF position.

Back Flush

1. Disconnect both hoses from the oil cooler pipes and then connect them to the opposite oil cooler pipe. This will allow the oil cooler and pipes to be back flushed.

2. Repeat steps 3 and 4 of the INITIAL FLUSH procedure.

3. Release the trigger (8) of the J 35944-A and allow water only to rinse the oil cooler and pipes for one minute.

4. Turn the J 35944-A water supply valve (1) to the OFF position and turn OFF the water supply at the faucet.

5. Attach the shop air supply to the flushing system feed air valve (2) on the J 35944-A and blow out the water from the oil cooler and pipes. Continue until no water comes out of the discharge hose (5).
