I'm working on my washer that won't spin. Machine running with cabinet off and bypassed lid switch. Fills, agitates, pumps but won't spin. Clutch is not spinning. I checked clutch and shoes and spring in good condition and tight, not slipping when tested by hand. Motor coupler removed and inspected and is good and spinning. Motor speed is same for agitate as spin cycle. Any ideas what to check next?

Motor not spinning clutch hub in spin cycle. I removed motor. Clutch will not spin when I hand spin the gearbox input shaft clockwise or counter clockwise. Spinning counter clockwise will operate agitator shaft back and forth. Is gearbox good or bad? When I look at motor standing behind pump shaft it is running in clockwise direction. (Should the motor run in counter clockwise direction on wash cycle?)

Thank you! I'll take the gear case apart tonight and see what's going on.

Awesome! Thank you for the diagram and instructions.
I opened and inspected the gear case. Found the problem in the neutral assembly #26. It is a sheared spin paul stud. The stud top was in the spin paul and the end is still in the main gear drive #19. When the stud sheared it made groves around the main gear drive and connecting rack. Would like to replace #19 Bottom and Pinion Gearcase part #389230 or the replacement # 285515 are no longer available. Could probably fix by removing stud end from connecting rack with screw tap tool. I decided to get a new gear case #1 part #3360630 but is no longer available. I got the replacement Gear case part #3360029 and it does not fit. When in place I can't bolt it in. Gearcase is 1/4 inch from support part#389350. Clutch clip is in groove and tight against the basket drive.
