Can the fork tubes be changed without stripping all the internals out ?
cheers guys
If you have the OEM damping cartridges, then nope: the extension stopper ring is attached inside the bottom of the stanchions.
Maxton SD25cartridges have internal extension stoppers, so the stanchion stopper rings are not required -- actually they must be removed. With those cartridges, you can remove/change stanchions without removing the cartridges, as with most, I think, USD forks (At least that's the case with Marzocchi USD forks)

As said earlier yes but need the correct ones as earlier (upto end of k4) and later (k5 onwards) are totally different internally and nothing is interchangeable.

Mines a 2007, if they can't be changed without a complete strip then i may send them to Brooks, is there a how to on here, can't find one.
A complete strip on the fork internals sounds daunting, but it actually is very do-able for anyone with a bit of hands on approach. Dave has an instruction step by step tutorial to remove, strip, clean & replace the oil for the forks. I've done it a couple of times & it's ok, just takes a bit of patience.

Thanks for the link, I followed that guide a couple of years ago to change the oil but I need to change the tubes and can't remember if they just pull out or is there more to it.
Take out the clip that sits above the seal & the 2 will pull apart.

Why have I never thought of that before? it's so obvious that'd work!
But then I like to flush the bottom of the legs with a swirl of petrol/degreaser to remove the sludge from the old oil & would rather have the cartridge out before I do that so I can wash them clean before adding new oil.
Good advice Hooli, I was shocked at how much sludge was in the bottom of each leg when I changed the oil in mine.
Each time I've rebuilt mine, Idrain all the old oil, pump the cartridge and then fill about 1/3 to 1/2 with kerosene before removing and pump the cartridge until all flushed out, a lot of gunk gets caught in the small passageways, a good flush of them and the bottom of the stanchion definitely helps. Could use petrol, but thats a solvent and any potentially left in is not good for new fork oil.
