The next job once I have finished the headlining install is to fit the new adjustable spring plates (rear suspension on the bus).

In the Bentley manual (super special know-it-all manual), it states a measurement of 23° + 50' is the stock / default setting of the spring plates for a 'Station Wagon' Bay.  

What does 23° + 50' mean?  (http://mkb-cc.yanksrule.co.uk//Forum/smileys/dontknow.gif)

I have downloaded a Inclinometer on to my phone, so I think that is telling me to hold the spring plate at an angle of 23° to get it stock, but what does +50' mean? What is the ' measurement? To me, it means feet / foot ??   (http://mkb-cc.yanksrule.co.uk//Forum/smileys/chiny.gif)

that's arc minutes...
1 degree = 60' (arcminutes)

1 arcminute= 60" (arcseconds)

written as 40° 15' 45''

Basically 23° plus nearly one degree, but minus nothing if that helps (http://mkb-cc.yanksrule.co.uk//Forum/smileys/chiny.gif)

Surprised there is that degree of accuracy in suspension setup on an old bus like that. Does it give any tolerances?

Utterly shocked, to be honest.  

24 degrees will be more than adequate ! (http://mkb-cc.yanksrule.co.uk//Forum/smileys/wink.gif)

Edit - about 23.83 degrees. (http://mkb-cc.yanksrule.co.uk//Forum/smileys/tongue.gif)

Ahh, yes that helps! It makes sense when you explain it like that. If you move it to a spline and it's below 23°, then you move it to the next spline which will be over 23° because of the way they are made, so go more, not less. (http://mkb-cc.yanksrule.co.uk//Forum/smileys/cowboy.gif)






Well, if you put one side on different from the other, it will affect the handling and ride-height.

Here is how I got on:

Thanks for the help guys! (http://mkb-cc.yanksrule.co.uk//Forum/smileys/thumbsup.gif)

you're welcome :)

Got your bushes sorted in the end, then ?

Yes, well, a compromise at least.

I forgot to post about them.

When I was getting some O-rings fabricated for the Cherokee, the engineering place I was at specialised in hydraulic connections and hoses. They had a machine there that they used to taper hoses to their connections. I cannot remember the name of the machine, but it was like a bench grinder with a special rig to hold what you are 'tapering'.

I asked if we could try the bushes in the machine and they agreed. The finish is a little rough, but there is about 1mm now taken off the largest / widest part of the circumference of the bush.

Hopefully that should be enough! (http://mkb-cc.yanksrule.co.uk//Forum/smileys/chiny.gif)

Top work there CP.

Do you have a calibration cert for the accelerometer in the phone to prove that angle? (http://mkb-cc.yanksrule.co.uk//Forum/smileys/tongue.gif)

Well he has it in a bag (http://mkb-cc.yanksrule.co.uk//Forum/smileys/wrapit.gif)
