Removing swingarm XT600 1991
 

Hi all

I've been struggling the past day or two to get the rear swingarm off. The shock is gone, and I've removed the bolt for the linkage under the swingarm. The whole back end is removed except it. I've removed the 22mm nut but can't pull the bolt from the right hand side. Is it threaded on as well? It won't budge and I can only rotate it about a quarter turn with grips - I don't have a 22mm socket and the ring spanner doesn't fit.

Any ideas? I feel like I'm doing something wrong. I've tried with the swingarm raised, lowered and with support under either the engine and the frame. I've tried tapping it with a hammer. When the swingarm is raised and lowered by hand, the bolt rotates a small amount.

any suggestions grateful.

Cheers
jim.

Here you can check out all bolts.

Ooly the nut is threaded on, the the bolt through the bike.

It sounds like the bolt is partly seized :oops2:

I installed extra greese-zergs to avoid that problem on mine, might be an idea when you get it sorted. Otherwise pull the bolt and grease it up every once in a while (depending on the use of the bike)

Thanks, that's one of my fears. It doesn't look as if it's been greased in a while. Next move I think will be to try and fill the swingarm up with grease and try to 'float' it out....

The other fear is that it's bent - which is why it won't rotate fully. That's less of a palatable thought.

Thanks - I've got this, so I can see what it should be - I guess I was after the sanity check that I'm not missing something obvious. Which I don't think I am!

They get corroded in from water and gunk getting in the plus the aluminum starts swelling when it corrodes from the reaction of the 2 dissimilar metals.
I do like said earlier ,Drill an 1/8" hole as far as possible( I have a 4 and 5 inch bit when needed) from the head then a cross hole or 2 for grease to get to around the bolt. Then drill and tap the end for 1/4-28 grease zerk.

Sometimes penetrating oil over a couple days helps along with an impact wrench to break free. Some hits with a brass punch and hammer finishes the job. Clean up the bolts and bore good before installing again. Generous coating of antisieze works too if not installing zirks.

OK, appreciate the explanation, thanks. I can put zerks in no problem - the bolt is already partially hollowed (don't know how far, but guess that's standard).

I'll see what I can do this evening, although I probably need a trip to the tool shop with the 'other' credit card. Shame.

Aha! Turns out I needed to use the medium persuader rather than the small one! I decided i'd been too soft on it so rather than tapping it I managed to rotate it with grips and then belted it a few times and it started to shift. After that it moved ok. I'll Use suggestions to put more zerks in - but then I think lubricating it generally will help.... It was all a bit dry in there. Interestingly the shaft looks to have a bit of surface corrosion but I'll defer judgement until it's properly cleaned.

Onwards!

Thanks for your help all..
