Frequently Asked Questions

It’s part of the drive/clutch assembly stack-up, acting as a thrust surface to control axial movement. Exact location varies by model—verify with your parts diagram.

Check your Graco manual for “Washer, thrust (3900)” and match to 15F250. If your model lists a different part number, use that exact number instead of 15F250.

We recommend OEM to maintain correct thickness/tolerance. Aftermarket substitutions can alter stack height and increase wear on gears and bearings.

Metallic shavings in the housing, irregular clutch engagement, excessive axial play, or visible scoring on the thrust faces indicate the washer should be replaced.

Clean mating surfaces, inspect adjacent bearings/gears, and assemble in the manual’s order. Torque fasteners to spec and test for smooth rotation before full reassembly.
