Filter/Breather Replacement; Hcu Maintenance Schedule - Schulte GLADIATOR RWP-1935 Operator's Manual

Filter/Breather Replacement

1. Before replacing the filter please make sure to shut down the system and allow it to cool down.
2. Unscrew and remove the filter cap from the tank
3. Remove the O-ring seal, filter bypass spring and filter from the unit. Place the filter cap on top of the filter
port without applying any torque to avoid dust/debris entering the system.
4. Withdraw the old filter and replace it with the new filter and place the bypass spring and O-ring seal as
shown and tighten the filter cap. The torque required to tighten the filter cap is around 75 to 85 ft-lbs.
5. Unscrew the breather cap and replace with the new one.
6. The breather cap is made out of plastic and comes with SAE-12 1-1/16-12 thread so the torque required to
tighten the breather cap is 78 ft-lbs. per SAE guidelines.
7. While tightening the filter/breather, it is the responsibility of the operating personnel to not damage the
threads on the ports as it will lead to potential cracks near the openings.
Do not open the internal bypass valve assembly port. Warranty is void if it has been
opened, tampered, or damaged by the customer.
