Hi my mates 2008 scott ransom 20 rear shock has gone ,
i always rebuild my own fox forks and shocks but im having problems finding out any info on these scott units i have stripped it and found the main seal worn and managed to get a seal that seams spot on,but have been unable to get the oil spec and amount needeed .The oil is dark green and thin, but the strange thing is the smells like car gear box ep oil
dones anyone have any info that would help ?
thanks alot !
This is an educated guess, but I would say it will be normal shock oil and most likely 5wt. Many shocks use this (including the original Genius Mk1 TC shock and the Scott Spark Nude shock). It probably smells odd as it's broken down and emulsified. Almost all Ransom owners seem to report annual shock issues! And also get specific rear shock oil as it apparently is able to deal with higher 'shear forces' which rear shocks are subject to!
One thing though, that shock must use an Internal Floating Piston, which seperates 'air' from oil - the air pushes against the piston to keep the oil volume constant. Many shocks use Nitrogen to charge the IFP (but some, including the original Genius shock used air, and you'll get away with using air) - you need to know a) what pressure the air has to be at (Fox is, I think, something between 200-300psi, a DT is 300psi and a Scott Nude is 500psi) and b) how you're going to get the air in - some kind of adaptor will be needed.
Good luck and post back as to how you get on.
