OutdoorKing Repair Forum Forums Restoring, Customising and Modifying Reel-Type Mowers advice removing jammed clutch shaft woodruff key

Need help trying to removing the woodruff key from the clutch drive shaft, the key won't budge. Tried penetrating oil, pliers, vice grips hammer and screwdriver but it wont budge.

Mate, sounds like a tough monkey you have there.
I have had stubborn ones, I normally get them out with a screw driver and hammer.
However you have tried that.
I wonder if you could heat the shaft to expand it, this can heat damage seals though.
Maybe soak it over night and try the next day, sometimes patience can work to.
I'm sure others here will have a technique.

Can we have details of the mower and photos of the problem area please?

Hi conquest 96, as grumpy has said, it's good at the OutdoorKing Repair Forum if you can us give the make, model numbers; complete engine numbers and some pics of the offending part and of the overall machine...this gives us the opportunity to give you the correct advice that is specific to your machine.

If I was to hazard a guess, I would say you were talking about a Scott Bonnar Model 45 engine shaft....the key, if it seizes in its slot; (usually because of egress of water or moisture) can be a stubborn devil to remove, in my humble opinion, I would try:
Using a liberal amount of penetrating oil over a period of 1 to 2 days and then tap gently on one end and being half-moon shaped, hopefully will slide up and out of its groove
Please let us know how you get on....
