95/96 rockshox judy sl cartridge dilemma

Trekybiker

Hello, I just took my 96 judy sl fork apart (plastic cartridge) and discovered that it had leaked all of its oil out. I had lightly rode the fork, and it had been about a year after its first service (done by me). I am at a standstill trying to decide what to do with my fork. I know the plastic cartridges were prone to leaking. Could it have just leaked all of its oil out as I was taking it apart, as It didn't feel too bouncy? Their is no corrosion in my fork, and the cartridge seal appears to work properly. Could you possibly pour fork oil into the fork, and make it a hydracoil? Any help or advice greatly appreciated. Thanks in advance!

As you said, the plastic dampers are a weak spot for the fork. Had many that have done the same.

I think there is a thread on here by srp selling new dampers, no experience in converting to hydrocoil myself.

If the rest of the fork is in good shape, I'd try and find a metal bodied damper. I used to have a couple of Judy fsx and converted them to air using the super rare englund/ecko sport conversion kit, but rarer than a unicorn having dined on a toothed hen, riding a rocking horse having a poo, while texting a mermaid.

Not too rare then. Not scarce like

I am working on a hard body kit. First prototypes are done. Fit is good. Function is not. Still need some tweaks. Stay tuned.

Kokies, that’s great news, especially if that happens this season!

I’m in the same position at Trekybiker — just pulled apart my ’96 Judy XC/Cantis (original owner) from my 94 1/2 Cannondale, and the elastomers were toast. A real pita to clean out. Pulled everything apart for a thorough inspection and cleaning to find the stanchions in nearly immaculate condition. Oddly, no “Wavy” spring in the damper side under the snap ring?

Purchasing new springs from SRP to replace the elastomers are an easy, inexpensive fix!

However, my plastic damper has long since lost its oil and I”m dithering about buying the SRP oil damper kit as the instructions from the Judy manual on doing so aren’t particularly clear (and the small, grainy pictures aren’t helpful). Read a few posts on the process (several times) that didn’t clear up the fog and couldn’t find a youtube video of someone tackling it, either. And if I were able to manage it, how long would it last?

So, that seems to leave me with two options right now:
#1, install new SRP springs and leave the non-functioning damper alone. With just new springs, would it ride like a pogo stick without some kind of damping?
#2, the other option I’ve read about some time ago is to replace entire Judy, less crown and steerer tube, for some version of a better Marzocchi’s bolt-on stanchions/brace/lowers from that era (pre ’98 IIRC), but haven’t been able to locate the post(s) for the exact particulars. Any insight on this would be really helpful. Don't know anything about their 1" steerer forks, either.

With the C’dales 1” steerer, my options are limited.
