skip Posted August 13, 2008 Share Posted August 13, 2008 Gday everyone. This may seem a stupid question but in your experiences, what is the best way to remove and refit an R model cab? Would you use a large beam through the doors an sling the ends of it? Thanks for any help.

Do not just place a sling through the door openings and hoist it up without a spreader bar. The roof and drip rails will buckle inward a bit from the weight if you do not use a spreader to keep the lifting force verticle.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

All are bent in the roof skin/drip rails attributed to lifting with a sling from a single lifting point. All cabs were fully dressed, (complete) when they were done, (not by me) and I get to repair them which is relatively easy and pays well.RobOn a side note: What type of voltages and frequency do you folks run down under?

If they would have used longer straps through the doorways there would have been a lot less compression force through the roof and drip rails. Of course they would have needed a lot more lifting height to clear the frame and transmission. That is the purpose of the spreader bar. One of the cabs was lifted off with a chain so you can imagine the damage to it! Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

David Posted August 14, 2008 Share Posted August 14, 2008 We use a beam with sliding "pockets" on top that adjust to width of the cab. Pick from the door frame with the doors open and as close to the front as possible. This is how the cabs are set in place at the factory.

Robi put the forks through the closed doors, seem to work ok.... when you actually undo ALL the lines also i orderd a cab rust section today, um its coming from USA i wouldnt be surprised if al the parts are still available there.

terry Posted August 15, 2008 Share Posted August 15, 2008 I have seen the door bent up by going through the window opening, open the door or take it off and use the door opening.

Your cab was lightened up by rust and lack of remaining steel! Air really is quite light in comparison to steel!

Rob Posted August 15, 2008 Share Posted August 15, 2008 True, i was more worried about it collapseing than anything. Ya done well. When you go to reinstall the "rebuilt cab" a lot of weight can be saved if the doors are not installed. I like to build empty cabs on the floor or dolly as it takes many, many trips up the steps to install the interior when the cab is on the frame. It is so much easier on the body, (mine) to not have to climb to install parts! Back when I was 150 pounds less, it didn't much matter as I had a much easier time just moving around.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.
