Fork tube removal.

[Aidan1150]

Last week I hit a bad pothole which luckily enough didn't damage the front wheel. However, a little later I saw oil weeping from the bottom of the near-side fork tube. Luckily I have a spare to hand so hopefully it will be a simple enough job to swap them over.

I plan on removing the inner stanchion first as if I was changing a fork seal. Then I hope to drop the fork tube down through the bottom yoke but I'm not sure if the bigger diameter at the top of the tube (where the seal sits) will pass clearly down through the yoke.

Have any of you done this job before and can advise?

I'm hoping that someone, maybe @Steptoe will know my best way forward.

Many thanks.

You need to pop the dust cover off the top end of it, Gently up with a decent flat thing pointing vertically up and a dunt with a hammer, being careful not to gouge the alloy!!

but Yes it fits through that is how I have done them for years

If you undo the top nut 14 mm HEX socket is best unless you had it out already? and a 22mm Spanner on the slider at the top yoke and once out, drop it an inch or two

You will see the titchy 3mm Allen Head bolt #3, once out it will let the air out and you can lower it down into the tube to minimise spillage

(Watch out for the even titchier O ring #2) As soon as you see oil you can stick the bolt back in to stop any more spills

NB the steering gets all floppy so set the wheel between two blocks and tie the handlebar back to stop from slappin you on the head! DAMHIK!

have fun

About 400cc of ATF or your preferred fork oil per leg my foreman at Motorrad asid ATF as its sole purpose is to lubricate and not do anthing else

P.S. There are a few ways to do it!

Some people drain the oil at Bolt 5 when the axle is out But that is up to you

Just Double check everything is done up correctly before you go for a ride

Really simple. Watch these two videos and you should be good to go.

Sorted my fork seals and pulled out and cleaned the tubes.

Many thanks chaps.

I have changed the seals several times so am well used to that and the first video there @Bandare was very useful. It is pretty much as I expected but I wanted to be sure. I should have thought to have looked at The Old Mechanic as I have seen a lot of his videos.
