92241 Gauge - Porter Cable

The 92241 Oil Level Gauge is a genuine CAT Pumps replacement sight gauge used in CAT pump assemblies found on compatible DeWalt pressure washers. Installed in the pump crankcase, the clear sight gauge provides a visual reference for checking the pump's lubricating oil level without opening the crankcase.

Pressure Washer Compatibility

DeWalt DP2800 – Applicable configurations
DeWalt DP3100 Type 2
DeWalt DP3100IC Type 2
DeWalt DP3700 Type 2

Verify the complete pressure washer model, type number, and CAT pump configuration before ordering. Different production versions of a pressure washer may use different pumps and crankcase components.

Part Function

The 92241 gauge provides a viewing window into the CAT pump crankcase so the operator can visually check the pump oil level. Its clear sight-glass design allows the lubricant to be viewed from outside the pump during routine inspection and maintenance.

CAT Pump Applications

Part number 92241 is also associated with multiple CAT Pumps product families, including applicable configurations within the 2SF, 2DX, 3DX, and 66DX series. When servicing the pump independently of the pressure washer, confirm compatibility using the exact CAT pump model and parts documentation.

When to Replace the Oil Level Gauge

Replacement may be appropriate if the original gauge is cracked, broken, leaking, missing, or has become damaged or obscured to the point that the pump oil level can no longer be reliably viewed.

If oil is leaking around the sight gauge, inspect the gauge and its sealing interface before replacing components. A pump oil leak may also originate from another seal, plug, gasket, or crankcase component.

Important Compatibility Information

Part number 92241 is a CAT pump component rather than a universal DeWalt pressure washer gauge. Do not select the gauge based only on pressure washer PSI, appearance, or equipment brand. Confirm that the pressure washer is equipped with a compatible CAT pump that specifies part number 92241.
