Part number 0089937 is a Front Cover Gasket, a flat sealing component installed between the pump's front cover plate and the main pump body or fluid housing. When the cover is bolted down, this gasket compresses to fill microscopic imperfections in the metal surfaces, creating a leak-proof barrier that contains the hydraulic oil or fluid material inside the pump under pressure.
A failed, damaged, or missing front cover gasket is a common source of external leaks. Over time, gaskets can become brittle, crack, or extrude from their groove due to pressure and chemical exposure. Replacing the gasket during pump service restores a proper seal and prevents fluid loss.
| Pressure Seal | Contains hydraulic oil or pump fluid within the pressurized pump housing |
|---|---|
| Contamination Barrier | Prevents fluid loss and stops dirt and debris from entering the pump |
| Surface Compensation | Fills minor gaps and irregularities between two machined metal surfaces |
| External Leak | Oil or fluid is visibly seeping from the joint around the pump's front cover |
|---|---|
| Cover Removal | Anytime the front cover is removed for service or inspection |
| Gasket Damage | Old gasket is torn, cracked, brittle, or shows signs of extrusion |
| Preventive Rebuild | As part of a comprehensive pump rebuild or seal kit installation |

Gaskets are typically replaced as part of a larger seal kit or during a pump overhaul when other wear components are also serviced.
The piston packing seals are the primary internal seals and are often replaced when the front cover is off.
The pump's check valves are accessible from the front cover area and are common service items.
A master kit includes this gasket along with all other seals, packings, and O-rings for a full rebuild.
