LTS RockShox Super Deluxe really slow rebound

[mattbrown]

The rebound is really slow on a recently aquired LTS, like get off the bike and watch it over a couple of seconds extend again. Ive tried dialing the blue amd red dials but don't see any difference

Could it be the spring is too soft? I thought it it was 650lb but can't see it printed on the spring anyway.

I doubt it's the spring. Probably needs a service, it's quite old now.

You could pop off the spring and try and pull the shaft, well pump.it back and forth as it may have something clicking the rebound port but ultimately if it has, it's going to find it's way back. The old could have lost is viscosity and have contaminants in it after all these years.

Just my thoughts.

Last owner put in too thick oil ?
As said - Needs a service.

I've just come across this video. And the 1999 version is easier to take apart because the spring doesn't need compressing to take off the bottom disc. Also I've left the trunnion fitting in place as well, as that doesn't need to be removed either to remove the body of the shock.

Also what he bought off Amazon, you can get cheaper via Aliexpress.

I think I've successfully rebuilt this shock. So I was able to remove the piston, drain the oil (which didn't seem much) and rebuild including pumping it up to roughly the 225lb mentioned in the video (I couldn't completely disassemble but I don't think I needed to). And the shock is now a lot lot more bouncy. Just need to play with the spring compression and it should be as good as new.
