Cab mount help

[aussiecowboy]

The cab mounts in my 57 have more or less disintegrated, I have bought the cab mount kit from vintage power wagon but I am a bit confused, there are four pieces, one has two rubber bushes, one has four and the other two have three rubber bushes. As mine are so far gone I'm having trouble matching up what goes where, can anyone help me out with some advice or pictures?

The left front uses a rubber bushing between the cab and mounting bracket.
No rubber bushing under the bracket. just washer and nut.

The other three corners get a rubber bushing above and below the mounting bracket.
Hope this helps.

Thanks for your reply Tom. I'm guessing that two of the rubber bushes make one spacer, so the one with two bushes goes on the front left, the others get tow above and one below, still not sure where the one with four goes.

If you have enough rubbers to make it up the way I said then yes.

Originally the left front got a harder rubber insulator than the rest.
So the aftermarket is not going to produce all those separate parts, they just make one size fits all.

I would call Vintage and ask. Not sure why one would have 4 bushings, unless
They just randomly bolt them together for shipping?

What purpose do the bushings below the mount serve? Why the difference in the left front? Just curious.

[Tom Petroff]

With the way it's mounted Dodge figured the cab is less subjected to frame distortion.

After reviewing my manuals I noticed that the,

Left Front uses one Thick rubber between cab and bracket. Nothing under the bracket.

Right Front uses thick rubber between cab and bracket and thick rubber under the bracket.

Both Rears use a thin rubber between cab and mount, thick rubber under the mount.

Also shim as required between upper rubber and cab on all four corners as
Needed for cab alignment.

The front left mount is different because of the proximity to the steering column. Excess movement there caused the steering column tube to crack/break where it clamps to the steering box. If you are Down-under, and your steering in on the right side, you want that single hard spacer on the front right side of the cab, not the left.

I no longer attach the steering column tube directly to the steering box neck. Instead, I cut the tube so it is about a 1/2" away and use heavy straight rubber hose, splinted with PVC pipe and clamps. This gives a flexible, watertight connection between steering column and steering gear, and it can be covered with an appropriate CV boot to make it look like OEM.

I like the way you think CD..

This wise man (^) is prolly correct about our right hand drives Heath.

Good point Dave.

I didn't pay enough attention to his location because it's not listed, Although
His "handle" should of been a clue!
Thanks for clarifying left or right hand drive.

Excellent explanation regarding the left front and steering issues, thanks!

Now, why the rubber under the mount? It doesn't seem like that would do anything? Obviously, I'm missing something. :)

Clark,
It allows the cab to flex independent of the frame at those points.
The upper allows for some cushion and give, while the lower allows for flex(give) upward.
Otherwise the doors would probably "pop" open more than they already do!

Thanks Tom, that makes sense.

[Cheyenne Dave]

The application of the lower rubber pad would make even more sense if you looked at early B-1 and WDX cab mounting systems. The 3 corners of the cab, away from the "steering" corner, used a coil spring with a castellated nut, on the underside of the cab perch.

I opted for 3-point mounting systems for both cab and bed. I know I have some pix somewhere, just need to hunt them up...or take more.

Hey CD, did you ever find those pics? Love to see them.

Thanks!

Still hunting up the album. Then I will scan and get those pix posted.
