Seized swingarm bolt

Hi all

It seems my xrr's swingarm bolt may never have been removed in 14 years


I have been beating it with a hammer and drift for a bit and gave up to give it some thought


Anyhow I haven't tried applying any wd40 etc yet but was wondering if there is any value or if it is a bad idea to drill two small holes in the engine case where they seem to seize?
From what i can find there is no engine oil passing that area as there are webbing's separating this from the main crank/gear box so it seems feasible.


The plan is to then tap the holes and put a grub screw or similar in the holes to keep the crud out and hopefully make this job easier in the future if is goes pear shaped again.

My xr400 has zerk fittings on the swingarm this might be a better place to put them?

I have seen somewhere that wd40 is a poor penetrating lubricant and there are much better options available.

I'm not looking to grease the bearings just get some penetration oil onto the shaft as this seems to be the location that seizes up.

I regularly do maintenance on bearings on my other bikes, but the previous owner/s didnt care to. So I don't think I could be bothered to install zerk fittings, or grease nipples as I like to call them .

Kroil is my go-to choice for penetrating oil.

+1 on the Kroil. I spent a long time with a swing arm bolt, then I bought the Kroil on advice. I heated with a propane torch a bit and sprayed it down. and let it sit. Did that 2 days, hit it with a BFH, and the bolt came right out!

FYI...

You have the two bearings pressed in to the swing arm. What rotates in the bearing is the collar. What has happened is the COLLAR has rusted to the swing arm bolt. The swingarm can pivot on the two collars but collars are rusted tight to the swingarm bolt.

The bolt and collars can rotate but will not slide out due to being stuck to the collars.

There is a guy that had this happen to his XR400. He ended up sawing off the swingarm.

If that doesn't work and before you get out the sawsall weld a 2' slide hammer to the swingarm bolt. Hammering the thread end (even with the nut on) will mushroom the bolt almost guaranteeing the need to saw it out.

Whenever I go to remove a swingarm bolt I loosen the nut a couple of turns before giving it a few whacks with the hammer. If it doesn't move I call it quits and tighten the nut. At least this way it's still together.

I also used kroil on my xrr and let it sit for a day. That swingarm bolt was in there!! What I did was loosened the nut then pounded with a drift and then alternated with an air impact back and fourth on the nut that's built into the bolt and then pounded again. It finally came out. Mushroomed the threads a little but re tapped and all good. In my case pounding with the drift never worked. The air impact back and fourth was the ticket.

Once it's out, sand and polish it clean, then grease it (and the insides of the bushings) with quality waterproof grease (Bel-Ray, Mystik, etc). Annual maintenance will prevent it from seizing in the future.
