The USD fork seal guide

[brownE]

Excellent post Luke, very informative.
Just finished doing the fork oil and steering head bearings on my Husky. I'd like to add when setting the fork oil level (your way is very sophisticated) - all I do is use a length of surgical breathing hose and tape the desired oil height on the hose, stick it down the fork tube until the tape aligns with the top of the fork and gently suck the excess out - works for me.
What's next - full tear down of a 4T???

Great info! we need more tech posts like these on here..... You just saved poor o'l ARROW an annoying phone call
With the hight is that for the spring travel or were you want the fork to be sett at?

Are you referring to the oil height?

When you say we need more posts like this, what would you like to see?

Happy new year for starters.
Yes the oil hight, is that the specs for the bike or personal specs? and i mean posts like yours with the forks and 1 ARROW did on the YZ450F gearbox etc.
The bits you don't find in a servive booklet.
I'm a grease monkey (petrol) by trade and can do most stuff on bikes just by pulling them down and seeing how it works but the little trick bits with the certain ways they wear or what to look for to know if something is going to let you down in the near future.
Because of ARROWS g/box post i found a gear in a YZ i'm rebuilding that was stuffed and i may or may not of missed it when it goes back together, that alone may have saved me a couple of hundred in gaskets and a major dummy spit.

I dont understand why manufactureres cant give fork oil in volume like they used to. So much easier i just put 400ml in each leg on the ktm. arrived at that amount by emptying oil into measuring container the first time i did the seals . Dont need to pull the spring assembly apart either so back on track faster

Clymer manuals list oil volumes.
Cheers

any chance u could do this tho the mechanically illiterate, such as myself. Sick of paying a hundred and god knows what to get the seals replaced every couple of rides out in the bush, my poor 03 ktm 450exc copes a beating

Great post there Luke, that's just given me the confidence to try it myself
