Well if we can have a 5+ page thread about what OS works best on the trail this thread can't be too far off topic.
I want to pull the lowers off my '09 66 RC3 so I can install a o-ring as a travel indicator.
I've dismantled many Zokes in the past, but not anything more recent than the '06 model. I started on my '09 but couldn't get the left side foot-nut loose. Searching MTBR and Google didn't turn up anything so perhaps someone can clue me in on this, and oil levels etc. and I'll shoot the steps as I get further into it.
The top cap looks like previous models:
Underneath, is the air valve a lock ring and the splines for the top cap.
Again like previous models. This is the left leg which looks the same as the right leg on a 66SL RC2
Since the top cap is attached to the RC3 cartridge, the cartridge nor the lowers can be removed from undoing the top alone.
Like previous models, the top cap can be loosened by using a cassette lockring tool (sans center punch)
It was way tighter than on my '06 66SL dammed near rounded it. So stay square over the top and get a good grip on the fork legs.
This is just to loosen the top if you wanted to drain the oil from above. This alone won't get the cartridge out. I do not know if the snap ring is what keeps the cart attached to the top cap but it seems likely.
Below on the right leg is the 15mm foot-nut for the right lower:
I don't know what this is holding but on the '09 888, the top cap only has a compression nut for the spring thus there is no thru-rod that connects the uppers to the lowers. So I have no idea what this footnut is attached to at least not until I get the left side undone.
The left lower leg has the compression adjuster which is held on by a single hex bolt:
The detents are internal so there is no spring or ball to fall out on removal.
Underneath is the adjuster shaft which also has a snap ring:
Note the left foot-nut is 17mm wide and only 3mm tall. Because of the bevel in most sockets, that leaves ~1.5mm of engagement.
To avoid stripping the flats it's best to file the bevel off the socket before using it:
This is as far as I got. I started turning the footnut but it did not seem to get much looser. It didn't seem to get much tighter when going back the other way.
So the question is how do I release the damper rod so I can pull the lowers? Undo upper or lower snap ring perhaps? I'd like to pull the lowers without draining the oil. I've seen it done by inverting the fork so the oil stays in the uppers, but that only works if you can keep the top caps on and sealed. I don't know if that can be done on '09s. If not it would be good to know what the oil levels should be. Of course I'll measure them anyway if I have to drain the fork.
So anyone got some info? Tnx.
Oh yeah and Happy New Year... gotta go downstairs and get ready!
