Replacing a chain slider on a Yamaha TTR250
Permalink  
 

It's a pretty simple operation. Just follow this step by step pictorial guide.

Tools needed:- wheel-nut spanner (24mm), socket set, hammer and drift.

Part needed: Yamaha part number: 10-4GY-22151-00-00 : SEAL, GUARD or an after-market item available here

Clear a space and get the bike up on a stand with the back wheel able to spin freely. 

First job is to get the rear wheel out. Next, undo the swing arm nut.

If the swing arm hasn't been out for a while you may need to drift it out with a hammer and drift.

Next undo the bottom shock absorber retailing bolt.

It should now be possible to wriggle the swing arm backwards to allow access to the slider retaining bolt.

Unhook the slider from the chain guard bracket.

The slider can now be removed by pulling it backwards and downwards slightly.

The following photo shows a comparison between the old and new sliders.

The following pics show the damage to the swing arm seal cap which would soon have allowed water into the bearings. This one was caught in time.

Fit the new slider and replace the retaining bolt.

Wriggle the swing arm back into place, replace the swing arm bolt and bottom shock absorber bolt and tighten to the correct torque. Put the rear wheel back in and check everything is OK.

Job done!

Just found this post. Mine is knackered so I've ordered an aftermarket one for thirty something quid, it should be here middle of next week. This guide (if you'll pardon the pun) will be invaluable for fitting it. Hope the bearing seal cap is ok... We'll see. Thanks Brian!

Thanks for the help :) was starting to think i may need a whole new swing arm at first!!
It looks pretty bad, but i don't think it has made a whole in the swing arm, would i be able to use this to fill the whole made by the chain on the swing arm?
I will contact local dealer tomorrow with the part numbers.

Thanks
Regards,
Dan

Dan if you go on boats.net and look up the TTR 250 you can look at the fiche blowup drawing of the rear swingarm which lists all the part numbers. You can either order them from there (but its in America and will take a while) or take the part numbers to your local bike shop that has a Yamaha account. I did the latter and it cost me about 25 quid and they were here in three days. I'm just doing it now actually! I found that the swimgarm was worn down where the chain had rubbed right through the slider so I'm fixing it up with some chemical metal. The part numbers are;

Parts for rear swingarm pivot.
part no. 6: WASHER, PLATE 90201-254H8-00
part no. 7: OIL SEAL,OSO-TYPE 93108-35004-00
part no. 8: COVER 30X-2219X-00-00

Two of each of the above plus chemical metal or similar if you need it.

Regards,

Pete

I've got a groove worn in mine by the chain, but it hasn't gone all the way through. As its not under pressure or subject to heat etc I think it'll do to make the repair with chemical metal so the finish is right and the new cap seals on correctly.

That's awsome!, what a brilliant improvement!!
yeah my swing arm looks like that above, has worn down so much!
Sorry to be a pain but is that the right chemical metal i need in the link above?
Does it just work the same as like body filler? or is it more technical?

Thanks
Regards Dan

It takes a few applications, and careful rubbing down in between aplications, to get the right circular shape for the seal. Also, a bit of silver spray on the swing arm whilst you have it out makes the world of difference wink

I use Chemical Metal itself which is readily available from Halfords etc - see http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_223979_langId_-1_categoryId_255230

I haven't used JB Weld or other similar products so can't compare. I am pretty sure they must all work the same though.

I got the cheapest (I am a Northerner after all...) chemical metal from Halfords, it was tube of putty that you knead together.

If you're not in a rush it won't take too long :)
I prepared and filled it in about an hour one night, left it 24hrs and sanded it down in half an hour the next night. I'm painting it soon, Brian which halfords colour matches the swingarm?
By the way I got my chain slider from Andrew R Lander Stowe. It was sent overnight, was cheaper than the Yamaha part and fits perfectly. In fact I think Brian (who else) gave me the link in the first place :)
It's at http://www.joatmoa.co.uk/ttr250/

I used to use Nissan Silver but it doesn't really matter if you are doing the whole arm. A big can of alloy wheel spray silver is worth keeping for all sorts of spray jobs on the TTR - except crankcases and case covers - which I still haven't mastered no
