Help, how thick should front cab mounts be???

I would like to know how thick the lower rubber disk is on your trucks where the front of the cab mounts to the chassis.

You access this from the wheel arch. I'd be even better if more than one person answered and I could take a guess on it from the stats :-)

I replaced mine with urethane disks, but I think they are a little wrong. How much wrong, I do not know.

Also, K6, do you have a dimensioned scale diagram of the LWB chassis on this site? even if its just a jpeg. I'm keen to see where the deck mounting points are supposed to be height wise relative to each other.

So, help! Please :-) If I could have this info in the next 12 hours that would be very very VERY helpful :-)

Thanks,

Fred.

Scrub the frame request, I found a copy I downloaded years ago. The dimensions are 568 and 1575 with a difference of 1007. pretty close to what I said :-) The height is listed as the same for the two front mounts, and the rear isn't listed, but looks inline from the image. Hmm. I guess my chassis repairs were a bit sub optimal :-/ Looks like the rear of the chassis is druping by quite a bit due to shrinkage of welds. Shlt happens I guess.

Still keen as mustard for info on those front mounts.

I sorted the other aspect out too. The cab lines are exactly level with the bottom of the chassis. Thus the front mounts are probably fine. The rear is sagging quite a bit, though. There is no way in hell I'm opening up that chassis for more welding... so I'll just have to put the look of the vehicle right with different height mounts for the deck. No biggy at the end of the day :-)

yah it does look like the back of the deck sags abit eh? probably about an inch up at the bumper to meet the body line nicely

Sorry, I just now got to this thread, I do have some crappy copies of the frame drawings in the B2200 Tech section. I have better copies scanned that will go into the new tech section.

Nearly two inches mate. I measured it with a string alligned with the cab lines. And yeah, it's those crappy scans that I have copies of on my HDD, sorry for stealing them, came in handy though! :-)

I dont mean to sound like a butt head, but are you saying the welds shrank 2"?

I hope you were joking........lol

No, over 2.2 meters to get 45mm height diff you would only need a few mm shrinkage. it wasn't just one weld either. It was major open chassis surgery :-)

Basic trigonometry, if your .1 degrees off and take a measurement 1 foot away the difference would be close to nothing. Launch a rocket to Mars .1 degrees off and you'll completely miss the planet.

In the olden days race teams would put negative chamber into the solid axle rear end a similar way. They would heat the bottom half of the housing near the differential until it was glowing red hot while supporting the ends on jack stands. When the metal got hot it would expand and push the end of the axle in the opposite direction and it's own weight kept it slightly stretched as it cooled resulting in a permanent change of up to 1 degree of camber.

Yep, Except the people I heard of doing that were just doing it with a press :-) They were also doing it to get around the rules ;-)

Just an example of some of the chassis repair work I did to it...



Note, the rear cab mount you can see on the right, it was disconnected about half way up - the new steel went past that further forward. There was a section in the front that I replaced on the starboard side too...
