howto rebuild '88 fork ?

Hello,

I'm quite a newbie in this domain, is there any trick to properly close '88 forks ?



Specifically the bush (in the green circle), how do you make it go in the right place on the fork ?

If I mount it on the fork tube impossible to have it go into the fork leg. Should I put first the bush and in a 2nd step the tube ?

thanks for you help,

Roberto

Je crois qu'il faut que tu le serres , au moins temporairement afin qu'il s'engage dans le tube.
Avec une corde ou un fil de fer. Non ?

J'ai essayer mais il passe pas ... will try harder :-)

I always mounted before the cylinder friction on the stem by tightening until it insert into the outer tube.
I do not remember any particular problems.
On the other hand I would not see how to do otherwise.
I hope you speak Italian.
If not, I apologize.
Parli Italiano ?

Certamente!

Questa sera riprovero', se lo monto prima non entra ma forse baste forsake un poco.

This evening will retry, if I put the bush first the the tube does not enter the leg, may be I have to force a bit.

Thanks

There is a manual in the Tech section for 88 bikes if it helps.

the upper bushing is driven into the lower forkleg with the steel washer and seal above it. all 3 are installed at the same time with what ever tool you use to install the fork seal this is explained in the owners manual.

Just grab and squeeze bushing onto fork tube while inserting. Keep pressure on bushing. Its tight. If you have one of those split seal driver tools that would be great to use.

If not, I have a real hard plastic tool used for autos that I gently tap that bushing in with to get it in deeper. Just a little tap all around to get started or seated into leg. Now should filed in. The washer can also help drive it in.

It tricky to hold and squeeze it in the recessed area on tube and slide it in

The spring and check value was removed to allow for oil to flow. The cage that holds
additional value mounted in a cage of sorts is different , it seem to fall out at wrong time
keep a eye on this also.

Love the top out spring.

I have just replaced seals on my 430 Auto and I used a bit of oversize tube to push it down and it went straight in When it was in I tapped it down using a blunt screwdriver as a drift on top of the steel washer to ensure it was fully home.

Thanks guys!!

Mistery resolved, basically there still was a bush in the fork which in my mind was solid with the fork...

this bush



was still in place on the fork



I looked at the doc (thanks for the pointer to the manual) and realized that had to be taken out and put back after the fork tube with his proper bushing :-) Better last than never ...

thanks!

very simple once you figure it out, just a lil more steps than the earlier forks
