superhondaman Posted January 12, 2006 Report Share Posted January 12, 2006 Are the Falcon's self service? the seals blow after about 12 months and it is getting dear to keep sending them back to chirpy Mr Falcon. I can get them re gassed localy but how do they come apart? Quote Link to comment Share on other sites More sharing options...
feetupfun Posted January 13, 2006 Report Share Posted January 13, 2006 (edited) I assume you are referring to Falcon Classic steel bodied trials shocks. The aluminium cover you see that looks like a seal holder is a push fit in the body. It is actually a dust scraper holder. Tap it off carefully with a punch. Inside you will see the shock seal carrier held in with a snap ring. Depressurise the shock and then you will be safely able to remove this snap ring with internal contracting pointed nose snap ring pliers. From there it is obvious. PS if the shaft and seal is still OK and you just want to change the oil, you can do it through the hole that the gas valve screws into.

superhondaman Posted January 15, 2006 Author Report Share Posted January 15, 2006 (edited) Thanks for that really helpfull & all the way from Oz! the shaft is fine its leaking oil so i presume its a seal inside? What pressure do the steel shocks use? any idea. Also how much/weight of oil to use? Edited January 15, 2006 by superhondaman Quote Link to comment Share on other sites More sharing options...
feetupfun Posted January 15, 2006 Report Share Posted January 15, 2006 My Falcon Classic steel bodied shocks are 340mm eye to eye and 100ml of 10WT fork oil per shock works fine. I found that if I used 5WT fork oil there was not sufficient compression damping. If your bodies are shorter you may need a different oil volume (to provide the correct gas space). To work out how much oil to use I measured what came out the first time I changed the oil (none had leaked out). I don't know what the standard pressure is meant to be but I have found that anything between 40psi and 70psi works fine. Quote Link to comment Share on other sites More sharing options...
woody Posted January 15, 2006 Report Share Posted January 15, 2006 Falcon sets the Nitrogen gas pressure at 90psi Quote Link to comment Share on other sites More sharing options...
ace Posted January 20, 2006 Report Share Posted January 20, 2006 If you give Robbin at Falcon a ring (best in the afternoon) he will tell you how they were set up originaly, including the various pressures of Nitrogen you can use and quantity of oil. 01929 554545 He can also supply original seals and bits. http://www.picture-this.co.uk/falcon/fcontact.htm Quote Link to comment Share on other sites More sharing options...
