Inspecting used Ohlins

[SaMMaE01]

I recently bought used Ohlins online. supposedly they were bought new, and only on the bike for a 4 month period. But I wanted to know what to look for when buying used ohlins, besides the fact that their the right shock for my bike. What kind of wear and tear etc.


Thanks.

Tear it down and look for wear shine on the orings and valving

how about identifying what shock it is? I see no corresponding number or anything.

I was kidding about tearing it down, don't do that unless you know what you are doing, they are pressurized at 150-200 psi.

There should be a part number stamped on it. If you go to their website, you can identify the shock based on the part number.

From there, you can download a user manual on how to set the preload back to default or base values.

In order to identify the spring rate, you will need to call an Ohlin's dealer.

1. Like Stan says, check the numbers on the body end cap- top by the body end eye- with the ohlins site or knowledgeable suspension person.

2. Count the number of rebound clicks. DO NOT FORCE the knob! go all the way in, then out until it quits clicking.Note: it may keep turning without clicks, but do not keep turning it. on some models it may be possible to disengage the adjuster. not a big deal, but sometimes a pain to get the threads started again. It should have over 25 distinct, positive clicks. if it has less, it needs a rebuild at least.

3. If there is oily grime on the bottom bumper, it needs a rebuild, or someone's motor blew.
4. look at the shock shaft right at the point it goes into the body. It should be dry. There should be no visible verticle fine lines on the shaft. double check for lines with your fingernail. If you can feel anything the shock will soon need a rebuild, and maybe a new shaft.
5. on piggybacks look for any accumulation of grime on the body/resy attachment casting. On some models-mostly sport bikes- a few of these developed cracks.
6.On remotes look for grime on the hose.
thats all you can check without disassembly. 199's idea!

Awesome, thanks so much, unfortunately I do not have the shock with me at work(although I did last night trying to figure out stuff) I'll seen when I can get around to it. working full time and being a full time student sucks. no time to work on the bike. Sucks even more because its getting warmer and warmer in the bay.

Ship it to a suspension specialist. I dropped off a used Ohlins at Aftershocks. Phil performed an inspection and threw it on the shock dyno, all for $15. :thumbup
