Calum my spring exactly same. have to check other measurements at later date, pos friday . thanks for the continued information its very helpful, we get to bottom of this R&D soon I'm sure .... Im sure I'm indebted to you by at least a few dram's......

I did get my rebuilt ohlins back last month and have been in heaven ever since, yes, I was back in flight! Just hitting 15,000 miles 😊
So it took a little time to get a GoPro video of the front shocks in action.
Is the 750lbs spring too soft?
Is it too stiff? As in the calculations above too soft?
Or is the 45 degree angle put too much pressure on the top of the shock?
All to be determined in due time 🙏🏻

I may reshoot another video going over R/R track and a very bumpy road.
I'm posting a quick video of the shock in action around my parking lot and street. More bumps around the 50 seconds mark and at the end there is more spring movement.

Going to work with Gary at Ohlins next week.

Cheers and very proud to be an American today 🇺🇸

Nothing too unusual going on in that video from my perspective. Not much travel, but it's entirely dependent on what you're driving over of course.

Does the suspension have drop - ie, when you let the car down, the shocks compress? Assuming yes, how much "droop" travel is there from having the weight on the wheel, to having it jacked-up? If not enough, ie. the shock is always at or near full extension with the car weight on it, that could be the problem.

The real question remains - what is the spring rate of the new springs vs. the spring rate of the originals?

There is very little drop off the jacks
First impress are the shocks seem to be working ok ?
Will do another video over a jump 😊

Hi JVS, do you have the original spec sheet or Order acknowledgement form.

Another TMer uploaded one a year or so back, it would good to compare the two.

I shot another video and edited it so we see more movement.
going to sent it to Gary at Ohlin's today.

Great footage! look like they working at a decent stroke to me!

maybe there could be a little stronger spring along with loosing up the pre-load some for more spring travel?
I just emailed Gary at Ohlin's, lets see what he says.

I see what you mean,there is a lot of thread taken up by preload. maybe a longer spring? Sure Ohlins will see things we can't and get sorted!!!!!

I did video the Ohlins shocks in action and Gary at Ohlins responded.
The springs do collapse but don't touch
Here is Gary's response;

JV,

It’s important to note that nothing was ‘broke(n)’ on your shocks. The rebound needle was jammed on one, which is traditionally caused by the adjuster being turned past it’s stop-point. The shock that was leaking, well, sometimes mechanical devices leak when they are not supposed to. The factors that make a shock leak have nothing to do with what it’s mounted on. It could have been an ATV, a motorcycle, or a 3-wheeled Morgan.

I’m concerned about the ‘hard metal to metal sound.’ That can’t be good. The spring should never coil-bind. If it is in a coil-bind condition, the act of binding will leave a tell-tale line where the coils touch each other; removing the yellow powdercoat.

Check the coil spring for the signs of coil-bind. If you find none, the mechanical sound has to be coming from another point in the linkage. If it is coil-bind, we have a stroke problem.
