unexpected leakege from front forks

Post by Gdgiò » Mon Mar 28, 2016 2:37 pm



in the winter task list, i had also the front forks refurbishment.
No because of leakege ,just for changing oil,seals and bearings by new ones. Yesterday duing my first ride few kilometers, i noticed the forks wetted by oil. At the first i thought i left some eccess of oil but after i cleaned them (both) again a very thin oil layer came again.

I can not image any mistakes i could have done in a so simple job but that's the fact. Further I noticed, on both forks, few very very very light skratches (i did not noticed them earlier)...probably the rason of the oil leak.
Only thing comes to my mind the upper bearing or the seal defective ...any advices from your side?
Unfortunatelly I need to dismantle the forks once more :oops:
thanks

If they did not leak before and had oil then it was not the scratches you notice now.
This is what I do

Are you sure you refilled the forks to the specified level ? I'm not sure what effect overfilled oil level would have, but leakage sounds like a possibility. It makes no sense that you developed a leak after changing the oil, if everything was done to specs.

I see you disassembled them to change seals and 'bearings' ( bushings ?). I've not had to do that job, but would check for any errors in reassembly.

I suspect you may have put the fork seals in upside down.

Is it both forks? Pop the dust cover off and see if there is any oil sitting on top of the seals. If there is it could have been put in upside-down.
It's not what you buy, it's what you build.

hallo

I have been working on the issue so i did removed the forks again for checking and I found the reason of the leakege !!
...to summarize my idiocy :| was the reason since as you have forecasted, i did installed the seals viceversa.

I can not believe! I know how they should be assembled but i did it,however, wrongly!!!
diassembly and reassy it tooks 3-4 hours but now is solved..carelessness may cost extrawork.

but now i am really ready to ride !! :P :P :P
