Oil Cooling Block (HD0332-03)

The oil Cooling Block is used to cool the oil in the transmission circuit. This is done by a valve.
Checking the oil cooling flow
1. Checking with a flow-meter
• Install a flow-meter between port K and the hose.
• Test when rolling.
• The oil cooling flow should be 3.96 gpm (15 l/min)
2. Checking with a bucket
• Run a hose from port K and run it into a 1.5 gallon (5 liter
bucket).
• Plug the hose that was previously going to port K.
• Engage the parking brake
• Put the engine to 2000 rpm.
• Push the Joystick forward. (The pressure will go up on the
circuit and the oil will go to the T port of block HD0332).
• When the oil begins to go in the bucket, wait 15 seconds and
put the joystick back to neutral.
• There should be 0.99 gallons (3.75 liters) in the bucket.
• If you have more oil in the bucket you will need to adjust the
oil cooling flow.
