Wiper motor on my tractor has a stripped shaft that the blade is attached to. The shaft has a knurled knob that is in turn knurled on the inside to slip on the actual shaft coming out of the motor. That inside knurl is stripped so this little knob that turns the wipe blade just spins on the motor shaft. Expensive fix is new wiper motor. Prefer not to go there.

Any one with ideas on how to now keep that knurled knob from spinning on shaft. Would expoxy work? Appreciate any ideas.

Merry Christmas to all.

You have wipers?

I would drill both pieces and pin them together, a 3/32" or 1/8" roll pin should work.

Drill a hole. Bolt or roll pin . On our 7000 series I just removed the wiper and use Rain X.

If it is like ones on a car it may be repaired.
Have done many with success on all.

Take a small metal pick and clean out all the groves on the shaft that the wiper arm fits over and get a new wiper arm.

Dale, I had the same problem on the ones on my Chevy pickup. Cleaned them up really good, put some JB Weld in there and then put them back together. The rest of the time I owned that truck, I didn't have any problems with them.

you could drill and tap the outside piece for a small allen head set screw if 2 are used set them ad 90deg to each other , JB weld should work also but using a set screw will hold the best. Drilling through the small motor shaft may cause more problems.
