Rear shock help

[Jeffb]

So, I pulled my shock, sent it off to be rebuilt, and now it has been returned. When they put it back together, they didn't line up the collar the same way it was, and now I can't line things up to reinstall it. I tried twisting the shock in the collar, but it was tight. I didn't want to use too much force, because the hydraulic line goes in through the collar, and I have no idea how it's connected inside. If I have no luck with this, I'll contact the rebuilder when they open on Monday, but in the meantime, can anybody tell me how to line up the eye of the shock where it was?

This is just a guess, but I'd bet compressing that spring would be involved in moving the collar.

I remember that the collar in the upper part, has like a split round washer so that it executes force once it is inside the slot of the plate where the collar is located, it is for safety and the collar does not come off. It is like the pins of the pistons.

So it should turn to the position of origin, by the way, surely where they did that work they did not make marks of their position, so now they themselves will not know the position of origin.

I can take a photo for you to see the original position.

Indeed, I have looked at the bike and the collar with respect to the original position, it is somewhat displaced.

I think I should be able to move it as I don't see that it is threaded, it is just under pressure and the round washer I mentioned earlier holds it.

Now I cannot move from home because I am waiting for a person, as soon as I can I will look at the shock absorber that I have as a spare and I will take a photo.

As you can see there is a difference in their alignment.





I don't have a screw here to hold the shock in and try to spin it.

Tried rotating it by hand but could not rotate the collar (preload adjuster).

I have connected two wires to a battery and by reversing those two wires, the pre-charge motor makes the collar go up and down electronically.

Thanks Digital. So how do I go about aligning it? I was thinking I would clamp the base, then put a rod through the eyelet and twist it.

Ok, leave me a while and I'll take pictures of how you can do it.
