New member here. Thank you all for this resource. Everyone here seems very friendly and helpful.
I’m halfway through the rebuild of a ’96 Trek Y-22 and have reached an impasse with the fork. Its a Rock Shox Judy XC. Upon disassembling the fork I was presented with the common ‘crumbling elastomers’. I’ve ordered and received the SuspensionForkParts.net refresh kit for this fork. I’ve got it as far as screwing in the top caps but here is where I am stumped: The left stack is too long. I am unable/unwilling to push the elastomer stack down as hard as is necessary to engage them for fear of stripping the plastic threads.
Looking toward the front of the bike the dampener is inserted in the bottom on the left upper tube. (There is a +/- adjust notation on that side of the fork indicating that is the correct side.) In that upper tube assembly, about halfway, is an immovable metal ‘stop’ that is seemingly welded into it. The piston of the dampener fits through the hole in the stop. Above the stop, below the elastomer stack, I’ve inserted the tan colored beveled hard plastic piece that pushes on the stack. I insert the stack and it sticks out way to far to be able to screw it in. The tube on other side of the fork, the right side, has to metal stop halfway into the it, so the elastomer stack slides right in to the correct depth.
The elastomer stacks are both approximately 8”/20cm. I was not able to measure the old elastomer stacks as I had to literally pour the pieces out. The few elastomer pieces that were complete do seem to be the same length as the replacements from the refresh kit. My inclination is that the stacks need to be different lengths but during my research that is never mentioned.
Does anyone have an insight to what is going on? I'm pretty sure I've messed somewhere along the way.
