Bent Rebound Tube

[dalandser]

I'm rebuilding these and I'm not sure if I should try to return the tube to perfectly straight as much as possible or if I run the risk of making it unusable if I make the tube go out of round - I've gotten a tiny bit of bend out of it with a mallet.

How do I

A. test to see if it flows / seals properly or at least opens and closes as it should and

B. if it should be repaired, what's a good method?

Thanks

Don't fuck with it, just run it.

I agree unless there was a kink big enough to worry abought

Cool thanks for the feedback - I got the bypass valve out and am planning on completely rebuilding these with new coating (steel it) on the body and new seals.

I cut off the reservoir mount (I'll smooth it down to the body when I get time) and I'm converting them to remote reservoir since they're going under the bed with a cantilever kit. Going to go to the hydraulics shop tomorrow!

Quick question: do the 2 o-rings on the bypass valve need to be replaced typically and if so do are they the small o-rings that come with this kit - I'm not sure if it will have enough for all 3 bypass tubes - it looks like only enough for 2 tubes.

One thing though is that the piston rings (that are like engine piston rings I guess on the main piston) look beat up - should I replace them?

So I learned those are called wear bands - for some reason I can't edit my post ^

Correct, that is called a wearband. Typically I will replace them if there is significant gold color showing or there are any type of wierd wearing marks, and if there is I check the cylinder for anything unusual

Thanks - I looked down the cylinder and the walls seemed clean enough from any scratch marks that they should be good to go. I may lightly buff the outside of the wearbands just enough to smooth down any small burrs on the surface. Just ordered the seal kits and got a can of Steel-it yesterday. Looking forward to seeing these things hopefully work as intended once they're all back together!

i wouldnt even go that far. either run them or replace them. personally, id just throw new ones on.

 

[christianewing]

Yeah just replace them at that point. For the few bucks it will cost you now for new ones, its worth it in the long run

Shiiitttt. I would run that wear band another time for sure.
