I fitted the top bearing kit that is mentioned in FAQ once fitted it should be the last time you have to do it .

If it's just a tiny amount of oil fix up the bearing and ride .

If it's a lot it should be emptyed and refilled with the correct amount

I dunno if its easy to refill yourself.. I noticed the FAQ states to drill a hole in the shock to remove the circlip?

Martin from Gibbs Performance rang a week or so ago asking about replacing the top bearing on a shock they had in for service/repair and I was able to help as we now stock them in our eShop.

Hopefully Justin and Martin at Gibbs can help future TTR owners by fitting them if needed whilst they have the shock in their workshop. The owner would still need to spread the mounting a tad to accommodate the wider bearing but that's an easy job and the bolts etc to do that come with the top bearing kit.

Just a small drill to make a spot where you can get under the circlip (I drilled in behind the clip and made a semi circle )  . Just knock the bearing away from the circlip first .

I have a screw driver ground down to a flat point that gets under the circlip they put up a fight but do come out 

Be patient an you will get it . 

And watch the clip when it does move they can end up in orbit . A bit of rag catches them

Got e bearing out. Thanks for the help. Now shall I bother getting another original one or the one TTRfan has mentioned?

Can I put the oil in my shock or can any bike shop? or is this a specialist job?

 

Cheers guys..

Well done!

If it helps you decide, retail for the new bearing is £47.26 plus, if you have damaged either of the collars, new ones are £10.97 each. Fowlers have the bearings in stock but not the collars. I think I have a couple of collars in stock if you need 'em.

To put oil in your shock you will need to release the pressure of the nitrogen first. After replenishing the oil, you would need to pressurise again with nitrogen so I would say that the job is definitely best left to a specialist. If I have any shocks needing attention I just send 'em off to Justin.

Cheers mate. I think i'll go with the cheaper option then in that case. The stock bearing doesn't look up to much I don't want to keep having to change it!

I am posting my shock down to gibbs performance as we speak. Thanks for you help guys

i am guessing that the top of the shock on the TTR shouldnt move up and down when I have the bike on the stand and lift the bottom of the swing arm up and down?

it don't seem right to me having free play there

"Excessive" play on the top or bottom shock bearings is an MOT failure and certainly won't help the handling wink

We have found MyHermes to be the cheapest courier for shipping shocks.

We like MyHermes because we can drop off the parcel at a pick up point rather than having to hang around for a collection from home. Plus the drop off shop is near the Post Office so we try and do the two jobs together. 

Justin should certainly know his way around TTR shocks by now wink

Does anyone know what make the rear shock is?

No make names anywhere on them. Can only think they are made by or for Yamaha Japan specifically for the TTR250. I think that we are all agreed that no other shock will fit.

i think you mean SPRING RATE vancor88 don't you?. actually i was wondering who makes TTR250 rear springs. we have a spring manufacturer here in Australia called KINGS SPRINGS and all their springs are exactly the same colour powdercoat as the TTR uses. might give them a ring and find out.

Whilst looking at some photos of shock absorbers I came across this photo showing the infamous "clicker" mechanism in its constituent parts. There have been a couple of questions about it recently so hope the photo helps explain how it works wink

I got a duff shock so that phone call might be sooner rather than later Pete!

My bro's TTR rear shock didn't so much start pogoing as went lifeless! There was only 3 clicks on the rebound adjuster which was also suspicious.

He was lucky enough to blag a good working shock on eBay so we did the swap and his old shock has been kicking about in my store waiting for attention. Today was that day!

I started off power washing it and it didn't look too bad underneath the crud.

I have a simple test for a shock which is to remove the spring and checking the damping action.

Dismantle shock1.JPG 

 

Compress the spring until there is enough room to pull out the slotted spring retainer:

Dismantle shock2.JPG 

This is what it all looks like dismantled:

 Dismantle shock3.JPG

At this point I pushed the shock together and there it stayed so no pressure in the system.

Dismantle shock4.JPG

This one will be soon on its way to Justin Gibbs for a rebuild.

I have nearly finished stripping my Raid for spares and just got the shock out. A good time to compare it with an OE shock which I just happened to have been working on today biggrin

Raid v OE shock.JPG

 

The main differences are that there is no compression damping adjuster on the Raid reservoir and the bottom Raid yoke is steel rather than aluminium. 

The Raid's top shock bearing is a bonded rubber affair compared to the rose joint on the OE shock. That might be no bad thing as I haven't come across a Raid one with any play in yet.

The Raid spring is shorter but the yoke is longer such that, overall, the shocks are pretty much the same length.

Having tried them in different frames the two are interchangeable as far as I can make out.

I am still struggling to find a sensibly priced bump stop for the 14mm diameter rod of the TTR's rear shock.

The other Yamaha offroad bikes (YZs and WRFs) use 16mm and 18mm rods so their bump stops won't fit snugly cry

Can anyone advise of a source please?

Brian

I popped into Bike Worx (now just The Worx as Jamie is doing cars as well) this morning to ask about getting some TTR bump stops and the guy I spoke to asked me to hang on whilst he priced them up. I spied that he was looking at the ORO catalogue so said not to worry as I have an account with them. I said I thought they might have a specialist supplier of shock parts but he said no. ORO's smallest bump stop ID is 16mm so I am baffled confuse

I will be interested to see how you get on!

Brian

Rear shock
Permalink  
 


Our rear shock on the raid has died, my brother has been trying to contact gibbs with no success so looking at other options as the mot is out and it's all it needs.

are all ttr shocks the same? There is one on eBay 

also has anyone had trouble sending or receiving shocks as I beleibe royal Mail won't touch them now as a mate lost a bicycle shock as they refused to send it

Hi there

Justin isn't brilliant on emails - best to phone - 01752 846888

The Raid and OE shocks are interchangeable and, because of the additional compression damping adjustment available, the OE shock is considered an upgrade. 

The shock on eBay appears to be missing its bump stop which isn't a good sign. The expensive bit is repairing the damper rod if it is worn or damaged.

We send rear shocks by MyHermes without any problems. Because they are pressurised with nitrogen they don't seem to be able to be sent by air freight.

There is a totally rebuilt one here that you can be sure is 100%

Brian

RE: Rear Shock Absorber - which grade of oil?
Permalink  
 


I have seen two different oils recommended for the rear shock, 2.5W and 10W.

Is there anyone on here good with suspension can say what should be used please? Also quantity needed assuming some spillage?

Brian

Bump - any info please guys?

I think that, given the choice, I would go for the thinnest oil I could get.
