Woodruff Key Replacement

Autocycler · #1 08-13-2008, 09:38 AM

I sheared the key off of the small gear behind the side cover...the gear that attached to the clutch. Has this happened to anyone else here?

Any tips on where I can find metric woodruff keys. I bought some key stock from the local hardware store that I can grind down to size, but I'd prefer to find an exact replacement.

I saw woodruff keys at westlacks yesterday. Not sure if they were metric or not but I did see them. Good luck. We also have a place called Fastenal they have just about anything you could want. Not sure if you have one locally or not.

Thanks for the tip. There are Fastenal shops near me...I'll check with them

Thanks,

Steve

Steve,
I don't know if you are still looking but Tractor Supply has a great selection. Not sure if they are metric though.

Update:
I just checked my recently purchased assortment and they are standard, 1/8" through 3/8" X 1.5" and are distributed through SpeeCo Inc. - Manufacturer of Log Splitters, Tractor Parts, OEM and Farm Accessories Golden, Co., perhaps they have a metric line and a vendor near you.

Good luck, Scott

I should think a lawnmower/chainsaw repair would have metric as most stuff is made in Europe., Asia, or Scandinavia

Does anyone know the size of the woodruff key? Is it an M3X3.5X9? I've found a few places you can buy these online, but would prefer to pick one up locally so I can get back on the road today.

It would help if we knew where "locally " is. I can probably source it near you.

I'm in New Orleans. I ended up buying the replacement 'semicircular bond' from gasbike.net. Cost me $20 for 2-day shipping for a 30-cent part. I had to file the edges of the key and the slot on the shaft to get it in. Drove down the block and the engine seized. Turns out the small bevel gear cracked in half. I think the first woodruff key must've been hiding behind the clutch somewhere and caused the seizure. Now I need to find that animated clutch assembly link to figure out how to pull the clutch apart and see if I can figure out for sure what caused it to jam up.
