Morning all, (Calling all
suspension guru's)
I have just performed a very basic test on the OME front shocks that we bought late last year. These have been sitting a shelf for around 9-10 months. I had them fitted but they didn't do the job as expected, so I refitted the original front shocks to our Terracan(problem solved, but very soft in the front). Anyway I thought I would refit the OME shocks to the front and see what happens, but before I did I would give them a quick check. It is very rough, but the differences are.....
well different....
Here are the results:
(This test was performed by compressing the shock to the bottom of it's stroke then using a stopwatch, timing how long it took to reach the top of it's stroke. I did this three times with each shock. Both of these are N162)
Shock 1_24.05sec/24.61sec/24.82sec
Shock 2_13.30sec/12.94sec/13.03sec
I know this is not the most scientific test, but at least it gave me an idea about the shocks.
One would assume that if the shocks are the same then they would extend at roughly the same rate, but that doesn't seem to be the case.
Cheers Greg

Looks like one of them is stuffed Greg. I check my old one after I put new OME on and three out of four would not come back up, but they had done 100ks.
Cheers Bruce.

You need a return spring load to really see whats going on.

Do gas charged shocks have to return up to work properly?? Doesnt the gas along with the valving, provide resistance for damping purpose, not to make the shock go up?

I think that the simple design of standard gas charged shocks results in this as a side effect, and if they did before and now they don't then the gas has probably escaped. Casper

The gas is only for cooling and stopping the oil from airating, which reduces the preformance of the shock (fading)

The test you did may not give you any usefull information.
A shock absorber is not what they really do, a better word would be a rebound controller?
A better test would be to put them on a car and do the bounce test

A little follow up.....
I rang a couple of companies, one in
Sydney and another in Brisy, and it looks like I might be going for a drive to Brisvegas, (with the OME shocks, so they can be tested properly), to seek another opinion on our Terracan susp, and to see if they can do anything about the double bounce.
I will post a report when this happens.
Cheers Greg

Drop me a line if you need a bed. Almost ideal setup for you downstairs at my place if you need. You still got my number haven't you?
Cheers, Trevor.
