Decided to replace the spacer on my DRZ's output shaft yesterday, this is a common weak spot because the spacer corrodes & slowly destroys the seal ending in total oil loss in the middle of nowhere.

I've had the parts for a while but just not got round to fitting them. I thought while it was in pieces I could fit a smaller front sprocket too.

OK, tools out - tab washer knocked back - nut wouldn't budge.

Bigger bar - more leverage - wouldn't budge.

Pop round to my local garage & ask to use their air gun. smile

Gun on - won't budge - BIGGER gun on - still won't budge.

Had a sleep on it. Ordered a new nut & today it went into surgery. I thought about using heat but didn't want to weaken the shft in any way.

3/16 holes drilled down the sides to weaken it's grip - big bar - wouldn't budge. Bike lifting up into the air it was so tight.

OK, this is not going to beat me.
Ground away one flat to almost touching the shaft & hit it with a mallet & punch.

The nut split & half fell to the floor - the other half was still tight & needed punching off. God knows how much Loctite the previous owner used.

Anyway, nut off/shaft OK/new spacer, o-ring & seal fitted, new 14t sprok ready to go on. Just waiting for the new nut/tab washer.

You will not beat me! Twisted Evil

I'm 15st.
I was sitting on the bike with the front pushed against a wall & my foot planted on the brake. My brother was pulling up on a 4ft tube until he was lifting me & the bike up enough for the back wheel to spin.
Bloody nightmare!
I thought drilling those holes would weaken the grip but didn't notice any differance at all.

I now know heat breaks down any Loctite but that means spending hard earned on a torch. Last resort mate. Laugh

£3.49 for a new nut was a cheaper option.

Nut/sprocket off, spacer out - what a relief..

New seal/spacer fitted. Std 14t to replace the current 15t.

Bloody hell Phil, there weren't any blobs of weld hiding in there was there?

Thats a nightmare though mate, well repaired. If that was my brother's it would have resulted in requiring a new gearbox haha Grin

Good job Phil.

Another little tip for everybody if you're struggling(not suggesting it would have worked for you in this instance).....

When attempting to undo your front sprocket nut the very best way to do it is to put the front wheel up against a wall DO NOT PUT THE BIKE INTO GEAR, get somebody to sit on the bike and apply the rear brake.

You then have the best possible chance of getting it undone without damaging anything, because as you try to undo it, the bike will want to move forwards via the pull on the chain, but it can't because not only do you have the front wheel up against the wall you have somebody applying the rear brake.

If all else fails, refer back to Phils post. Laugh
