This weekends job is to raise the bus up a bit (I must of eat too many pies ).

In all the years of owning a VW, I have to admit that I have never adjusted spring plates before

I guess it's never too late to learn a new skill ?

I need to take the spring plate off, rotate it, and reassemble (wow, that's sounds quite easy when I say it quickly ).

I have 2 questions.............

1. How do I hold the torsion bar in place whilst pulling the spring plate off ?? (So that I only have to worry about the outer splines).

2. What is the conversion between number of splines and distance moved ??

I need to raise the bus by about 2", so how many outer splines does this mean ???

Is there anything else I need to be aware of when doing this job ?? (As I have a unique skill of messing things up ).

Thanks,

Phil.

phil, there is no easy way to get it out and leave the torsion bar in place.

what i usually do is get a sprit level and score a horizontal line across the spring plate surround and the torsion bar end. Then remove, the spring plate and the torsion bar. Whack the end to get the torsion bar out and clean and regrease it, then put it back into the tube so that the scored line is level. You also have a datum to adjust up or down from, for the outer splines then.

However, I think that 2" is going to require a combination of inners and outers. maybe +9 / -9

See this matrix for guidance. (Its for beetles but accurate enough for buses as well.)

By the way, whats with raising it up? Lower the front to match if it's sagging a bit!!

Thanks Monkey.

Looking at the Volksworld link, 2" = 1 x outer spline

I have adjustable spring plates, so can do fine adjustment with them.

There are 2 reasons for my lifting job.....

My front tyres rub when two ride up front (and I hit a bump).

And I'm reducing the profile of my rear tyres (which reduces the radius by 1").

Yeah, next line down, lol!

Good luck.

So after loads of stress, and pulling the whole torsion tube out by mistake (I knew I would ), I have got it back together, and if anything is now lower

So the obvious question I should have asked yesterday is which way to turn the spring plate ??

I have turned it downwards, but this doesn't have seemed to have done the job !

Any tips please ??

Phil.

Somehow I turned the inner spline anticlockwise, and the outer clockwise, and they cancelled each other out

Had another go today, and perfect, 2" up each side

Thanks for your help yesterday Monkey

Phil.
