can't find rotor removal tool

[Guest]

Trying to get rotor off my 80 850 and can't find bolt or tool to fit it. It a 14mm 1.25 thread. Can't find any bolt to fit on line or anywhere locally, and no tool on line either. All tools are too large or wrong thread count. I know someone must have found something to work? terrylee

swing arm bolt?

Gotta be a bolt supply place close??? Someone once said the axle bolt threads are the same...but I have never tried that route so someone that actually has should advise on that.

Check your PM box.

Tried spare swing arm bolts and axle bolt from parts 850 I have and too big. Even tried oil plug and it's 14 mm but I guess the wrong thread count since it won't screw in. terrylee

The oil drain plug should be 14X1.25, same as a spark plug. It's hard to tell what might have happened with a drain plug (might be an oversize replacement?), so try a spark plug in the hole to verify the diameter and thread pitch.

If it's 14mm but the plug won't thread in, it might be 1.5mm thread pitch, which is a lot easier to find.

If it's larger, it's likely a 16X1.5 thread -- I have a bolt, or you can order one from McMaster-Carr.

Sorry, I don't remember off the top of my head...

Just checked on my spare GS850 engine: it's definitely 14mm X 1.5 pitch.

I have a bolt I found at a well-equipped hardware store.

Here's my crappy diagram of how to use an 8mm socket head bolt to avoid bunging up the threads in your crank:

Thanks Brian, you're right I don't know where I came up with 1.25? Off to buy right one, found locally.
