Part number 805-250A is a Face Plate Oiler Assembly used to provide controlled lubrication to the reciprocating shaft or piston in various air-powered pump models. This assembly ensures the proper amount of oil is delivered to critical moving parts to reduce friction, wear, and heat buildup. It is essential for maintaining pump performance and longevity on compatible units.

The 805-250A Face Plate Oiler Assembly is a lubrication component installed on the pump's air motor face plate. It meters a small amount of oil into the incoming air stream, which is then carried to the pump's piston, cylinder walls, and other internal moving parts to ensure smooth operation and prevent premature wear.
A clogged, malfunctioning, or empty oiler can lead to increased friction, scoring of the piston or cylinder, reduced pump speed, and eventual pump failure. Regular inspection and maintenance of the oiler assembly is a key part of pump service.
| Controlled Lubrication | Meters oil into the air supply to lubricate the air motor internals |
|---|---|
| Friction Reduction | Provides a protective film on metal surfaces to minimize wear |
| Heat Management | Helps dissipate heat generated by moving components |
| No Oil Delivery | Oiler is clogged, broken, or will not feed oil despite adjustment |
|---|---|
| Constant Leaking | Oiler drips or leaks oil externally even when the pump is off |
| Physical Damage | Cracked bowl, stripped adjustment knob, or damaged sight glass |
| Pump Wear Symptoms | Evidence of dry running like scoring, overheating, or loss of power |
Part number 805-250A is compatible with several models of air-operated pumps. Always confirm fitment using the correct parts diagram for your exact model and serial number.
| Compatible Models | Component |

| Impact 1140 service | Face Plate Oiler Assembly |
| Impact 1140 I and IA | |
| Impact 1040 | |
| Helix VR | |
| Helix FR |
The oiler assembly is part of the pump's lubrication and air system. During service, these components are often checked or replaced together.
Includes piston, rings, and seals for the air motor. Proper lubrication is critical for the life of these parts.
Ensures clean, dry, and pressure-regulated air is supplied to the pump and oiler assembly.
Use only non-detergent, air tool oil specified for the pump. Incorrect oil can cause malfunctions.
