er.. that is the rear disc. At that measurement it's less than 4.5mm thick which, I think, is out of spec...... innit ?

Sorry, I meant the other side of the rear disc as we could see the front. Doesn't look very scored at all.

You need the correct type of Rawlbolt, the tubular one not the cast.

See pix and comment in this post by me last year:-

Thanks for your reply Steve - much appreciated - off to buy the correct bolt now. Fingers crossed that I can get it out then.

I bought M6 expansion bolt from Wickes - it looks like the right thing but  it is  too large to fit. I thought if it was M6 it would be OK - does it have to be a Rawl. bolt ?

The other two bushes came out easily so I hope the problem one will probably come out with the correct puller.

 

I bought a pack of 4 M6 anchor bolts from B&Q. 2 wouldnt fit. 1 would go in with a bit of force. the last one just slid in. You can always file the end down if it wont go in

If it is the head of the M6 bolt that doesn't fit, I had the same issue which was solved by sticking the bolt only in the chuck of a drill, then applying a file to it so it rounded a little. That then fitted a treat. I appreciate that by now you may have already been!

I bought a pack of 4 anchor bolts from B & Q which looked more like the right shape. None of them would fit so I am on the verge of giving up - fortunately I haven' applied any force or damaged anything - just greased the other 2 parts of the linkage and re-assembled it all and stopped for a cup of tea. 

 

I have been cursing the linkage design all afternoon calling it abusive words one of which rhymes with anchor.

Hi all,

 

Did the bush job on mine a couple of weeks ago and tried various methods of extraction including the 6mm rawl bolt, which didn't fit, so I ended up using an M10 tap screwed into the bush and used a long punch from the opposite side against the tap and gently hammered it out. Sorted. The M10 doesn't cut into the bush too deeply so it can be re used no problem.

 

Cheers.

Trumpet - This sounds promising but a bit dangerous if you are inexperienced. Is it difficult to screw in the tap ? How deep do you have to screw it in ?

Thanks Tom

[leehenty]

How did you get a tap to cut into the bush ? they are usually hardened. Be careful using this hammering out method, you run the risk of breaking the lug on the frame if it is really stuck.

[jono49]

I've used this technique before in desperation, but it wasn't as critical as this job!!!!..........break that lug the bikes a write off!

[Trumpet]

Hi guys,

 

The tap screwed in very easily as it was new and therefore very sharp. I let it go in about an inch or so and it gripped enough to tap it out - no pun intended. As has been said many times, this is not the method to use when the bush is stuck but it worked for me with the bike being two years old and twenty thousand miles.

 

Cheers.

after a check around my shock mount I have found some play in the bush this thread is referring to so it looks like i.m going to use one of the above methods of removing it . would the play have any effect on the handling of the bike at all  ?

I doubt you would notice it unless it severe.

[yorkie900]

prob about a mill of play side to side.

I read this thread prior to doing my suspension clean up when I got the bike, and when doing it luckily everything went fairly smoothly and all collars , seals etc. were cleaned, re greased and refitted.

I noted when doing it the seals weren't fitted with springs and are therefore 'grease seals' but on reading the service manual this morning, just to check something, it lists the seals as '8 x oil seals', (section 4-66), it might be a daft, simple question, but does it matter?

Cheers

[deeboy]

Hi,

 

Going to order new seals for the rear linkage...I assume best to replace with new rather than clean and reuse old seals.  Also dealer says I will need 8 new seals but a previous post says 6. Can somebody please advise.

Appreciate your advise.

Thanks

[Rallyist]

6 in the linkage and 2 more in the swinging arm dog leg anchor point.

[Bathy]

After talking to leehenty at the weekend I took his advice and had a look at the linkages on my bike.  Did the two on the link arms before the midges got the better of me.  So it is 2 down 2 to go.

Both pins came out easily enough but the one on the swing arm was very dry and the bolt was starting to show early signs of oxidisation.  Cleaned up and packed with grease.  Lets hope the other two are as obliging, gave them a spray with WD40 in preparation.

[Bathy]

Well had a go at the other 2 bolts, the one on the rear shock came off easily enough but the pin in the frame is tight, looks like I am going to need to try the extractor method. 

A trip to Wicks is called for.

[big dave]

Invited Martin (Bathy) up to use facilities at chez BD to get the reluctant bush out.

 

It were a tough little bugger to extract. The 6mm rawbolt wouldn't fit down the bush centre, so with a little help of the grinding wheel and an expanding bolt I found in my odds and sods tub we came up with a expansion bolt that would fit.

 

Still wouldn't come out (little bassad).

We only succeeded in extracting the bolt from the bush.

 

A quick roughen up of the bolt on the grinding wheel in an attempt to get more purchase and a spray of RAF "freeze and lubricate" finally resulted in the bush admitting defeat and a smug smile on both our faces.

Thanks Dave, nice workshop, certainly better than lying on my gravel driveway trying to shift the reluctant pin.  Great job.

 

I got my oil change done, all ready for France now.

 

BTW who's the grey haired old man in the last picky - oh its me!!
