Ride height for a traveller
Posted: Tue Oct 02, 2012 7:46 pm
After a somewhat solid ride with a lot of deflections from strong gusts of wind while driving at speed on the M42. I decide to check my ride heights to see if I need to adjust any thing.
The measurements are:
Nearside Lower trunnion (link) = 8"
Nearside centre of front torsion bar = 9 1/2"
Nearside centre of rear torsion bar = 8 3/4"
Offside Lower trunnion (link) = 8"
Offside entre of front torsion bar = 9 1/2"
Offside centre of rear torsion bar = 9 1/4"
Nearside centre front spring anchorage = 9 1/4"
Nearside centre body rear spring anchorage = 14 1/2"
Nearside centre of bolt on rear spring = 12 1/4"
Offside centre front spring anchorage = 8 3/4"
Offside centre body rear spring anchorage = 13 1/4"
Offside centre of bolt on rear spring = 11"
From looking at the workshop manual the measurements should be:
Nearside centre of front torsion bar = 10 11/16"
Nearside centre of rear torsion bar = 10 11/16"
Offside entre of front torsion bar = 10 11/16"
Offside centre of rear torsion bar = 10 11/16"
Nearside centre front spring anchorage = 10 9/16"
Nearside centre body rear spring anchorage = 15 7/16"
Offside centre front spring anchorage = 10 9/16"
Offside centre body rear spring anchorage = 15 7/16"
So I am down by 1" on the front and have a twist downwards towards my offside of 3/4" but even so the back should come up by 1 1/2" any way.
The thing is I use radial tyres not crossplys so what should the ride hights be for radial tyres?
It looks like some reconstruction of the rear is needed, but what do I need to do to rase the back end to the correct height?
For info, back in the mid 1980's I replaced the rear wood and had the rear rebuilt, so any referance points have long since gone.
