Graco service literature references 287770 as the motor fan kit for select XR, SR7, ProLTS, and GX Electric models. Check your exact model/series (e.g., ProLTS 170/190, GX 17H211/17H214) before ordering.

Overheating near the motor, thermal shutdowns, damaged or missing fan blades, or scraping noises at the motor endbell typically point to a failing fan.

Disconnect power, relieve pressure, remove the rear shroud, swap the fan and push-nut, then verify free rotation before reassembly. If the shaft won’t turn by hand, diagnose motor/gear issues before running.
