Shock seal cleaning

Recommended Posts

My shock seal seems to be leaving a tiny bit of oil on the shaft after it rebounds.. the bike has been sitting all winter and i just noticed it now.. i was wondering if u can clean the seal like u can on the forks?? My mud flap was ripped from the new tire i threw on so dirt most likely got in there...

I had a shock seal that leaked sightly once on a CR250. I took the seal out and boiled it to soften the rubber re-installed it and it didn't leak over the next year.

Running without a mud flap is a pretty good way to pit the shock shaft and get dirt into the seal.

i didnt choose it that way ahah it just eneded up like that. i found it out after the ride. It was cuz of a new tire and a larger front sprocket that didnt allow the clearance also the mud flap wasnt a cooperative piece of equipment. it would constantly hook onto the tire whenever i rolled the bike backwards

I dont know if this can work on the shock ,but the tearoff trick works on the forks. Try it and see if it works.

I dont think I would run it without addressing the seal leak. The shock does not hold much oil. If more has leaked out you stand a real chance of ruining the shock shaft. This is an expensive repair or it would be new shock time.

It is unlikely that the fork seal trick will work with a shock. The shock fluid is under pressure from the nitrogen in the bladder (about 150psi) The seal is quite hardy. If you did manage to get a tearoff between the seal and the shaft you would probably let a fair quanity of oil out of the shock as well causing the bladder to expand, accelerate the wear on the bladder, and ultimately cause it's failure.

Hence why I said I wasnt too sure. The tear off trick does work on the forks though. I had a slight leak on my one fork. After sticking the tearoff a couple of times into the seal managed to get it to seal again.

You take a tearoff and you slide it into a leaky fork seal (after you remove the dustseal) as a last attempt to clean up and possibly fix the leaky seal. If that fails it probably means a seal replacement

i have the same problem when i run a paddle on my bike, I decided to just bite the bullet and go buy a new chain cutting it a little longer so i wouldnt have to take off the mudguard. I just wouldnt be very comfortable riding without a mudguard.

the tire has rounded off enough now that it hopefully isnt sharp enough to eat another flap. ahahah i just took the shock to a shop for inspection. its nice to let someone else do the work for once
