It’s been a while, but photos are included this time …
While waiting for the WUR rebuild parts, I decided to reset the ride height. The front was about right at 620mm (it was easy, so that got done a while back), but the rear was sitting a little high, probably by 20mm.
So off into the garage.
Of course I never get distracted, so the first thing I did was reset the steering wheel. It was set 1 spline off from straight ahead, was really annoying, but I kept forgetting to sort it.
Back onto the ride height, and after a whole lot of googling, I decided that I would try 30’ swing arm / torsion plate angle, aiming for 605mm to the underside of the wheel arch.
I will detail what I did shortly, but suffice to say, I thought about things overnight, and did it all again today. Rather than just leaving the swing plate to torsion tube wherever I set it when I reassembled the suspension, I decided to check a few things.
Firstly, with the SC swingarms, I appear to have 50 or 60mm ride height adjustment. So, I elected to set the eccentric adjusters at about 2’ from maximum low, so that I have a little adjustment downwards, which will enable both sides to be tweaked to be the same ride height. I have more than twice that adjustment available to raise ride height. My logic is once set low, I am only likely to want to raise it if fully laden, like when I go to CLM (hopefully), so leaving more adjustment up than down.
I of course managed to get more distracted, although it was the post-person’s (politically correct for a change) fault, ‘onest guv. Firstly, yesterday I received my fire extinguisher, so had to fit it.
Hope that I never get to find out whether they work in the real world, but just in case I need it …….
Then today, my replacement exhaust baffles arrived. For scale
And once fitted (this time with a locknut, so hopefully I won’t lose another)
Enough of the distractions, so, wheels off
Removed torsion plate cover
Yesterday I moved the rear ARM drop link out of the way
But today I didn’t bother, and managed to access everything I needed to without issue. It might make life easier when I have my 12mm allen key and try to adjust camber and toe.
I used a block of wood in my high lift jack to take the strain off the torsion plate

And disconnected swing / banana arm.
With everything swinging in the breeze, I checked the torsion plate angle.
Yesterday it started at 33 & a bit, and someone’s comprehensive chart suggested that I needed to remove 3 or 4’, so a target of 30’ seemed about right. Today, having changed the eccentric adjustment, I reset it to 30’
Having built the suspension fairly recently, the torsion bar came out fairly easily (after some levering with a pry bar). To get the torsion plate off the torsion bar I used mole grips and a pry bar.
I know, don’t mark the torsion bar and set any localised stress points.
By playing with moving the torsion bar and counter rotating the torsion plate by an equal number of splines, we ended up with 30’. Unfortunately, once things were all torqued down, things had changed slightly
So try again, and better this time
Then, as they say in all the best manuals, reassembly is the simply reverse of stripping. Today, without driving, just bouncing on the rear, we have
I’m expecting the ride height to settle a further 10-15mm, but can tweak just using the eccentric adjuster to get where I want. I’ve ordered a 12mm allen key, as I can’t get my 12mm allen socket into the camber adjuster. I did guess which way was more negative camber, but as I’ve ended up with about +2 rather than -2, it’s clear that I guessed wrongly.
