monty_trials Posted September 4, 2013 Report Share Posted September 4, 2013 Hi peeps I removed the seals from my 2006 Gas Gas 250 pro, and the replacement seals are the wrong size as the new ones are smaller??? I read somewhere that some of the Gas Gas forks are a "upgraded size forks?" The part number reads in this order "40. 52.2 10.5" Been looking on ebay and they seem very expensive for just 2 seals as i bought the other smaller size for only £2.40 for the pair! Other ones on ebay read 52.2 40.10.5??? Does it matter what order the numbers are? Can anyone tell me where i can get them at a normal price? Already spent a lot on the bike so dont want to go over bored!! OR....With fork seals is it better to spend a bit more than usual so they last a bit longer?? Been out the trials game a while now so need as much info and help as possible, as i bought it as the owner said it was trials ready but after riding it just half a day realized it needs loads doing to it, as the bike is pretty much in bits now please help Quote Link to comment Share on other sites More sharing options...

tltel Posted September 4, 2013 Report Share Posted September 4, 2013 Or you can take your seal to a local seal/bearing supplier and get them off the shelf. Or try Simplybearings web site. TLTEL Quote Link to comment Share on other sites More sharing options...
monty_trials Posted September 5, 2013 Author Report Share Posted September 5, 2013 thanks guys ive ordered the 40. 52 10.5 not the "52.2" been told there is no such size or it won't make a difference? Anyone else had this issue? Also when i removed the original, it was a hell of a job? as they both seemed like they were very tightly fitted against the cast of the fork??? I did remove them but i nearly destroyed them when removing????? For future reference...Is there a proper way of taking them out? Quote Link to comment Share on other sites More sharing options...

A little careful heat from a propane torch or a heat gun will break the bond and the seals will come out a lot easier. I always use a torch with no problem but some are afraid of burning something, never have. 1 Quote Link to comment Share on other sites More sharing options...

bilks Posted September 6, 2013 Report Share Posted September 6, 2013 As for removing them,remove the bolt at the bottom of the leg,and make sure you remove the clip that hold the seal in the leg,then it should be a case of pulling on the stantion cpl of times and it should come out fairly easily, complete with the lower bush.
