Before I install the tub back on the frame is there anything that should be done first? Right now I am addressing any fluid leaks in the trans./trans.case installing the fuel lines. I plan on doing the wiring once I have the body back on. I have also filled the steering box full of lubricant.

Are you using all the old tub mounting hardware and rubbers? If you are did you carefully mark them on removal so they end up back on the correct mount?

You may want to study the TM's & ORD 9 very closely so you can better organize your attack on the "Fitting and alignment of the tub"

I have a sub-album for the A1 tub mounting you may find something there that helps.

But before you hoist the tub take a quiet one hour or so siesta and set next to your chassis with a cold beer, drink or whatever relaxes you and study the chassis. You will be surprised how things that have been right in front of you during the long resto process but you never noticed because you were busy working on something will suddenly pop right out at you. As a rule if the tubs off then carefully inspect and repair everything that sets below it before you install it.

A couple of install procedural items you should review are the tub alignment procedure which starts at the rear crossmember and works it way forward. By the time you reach the firewall area you will find a constant adjusting of the tub position becomes necessary as you check brake/clutch pedal alignment and starter pedal alignment and steering shaft alignment as well as it will be wise not to start the final tightening of the tub mounts until you have also temporarily fitted the front sheet metal. Use the TM 9-8015-2.

Thank you for the tips Wes. I saved most of the mounting bolts but the rubbers were flattened out and in rough shape so I made some new ones out of some material I had on hand which was the same thickness.

The thickness is very important to tub alignment.

The pads vary a lot in flat dimensions and thicknesses. They are not that expensive in a kit.

Is the pad thickness really that crucial that a 1/16-1/8'' would make that much difference? I have no problem purchasing a kit just wondering what would happen if the wrong thickness was used.

Assuming a straight frame and straight tub the difference 1/8 to 1/16's can make in 10 feet or so is very measurable. There are steps you can take to check the tub and frame for straightness (trueness) and all are simple geometry. How much difference can 1/8" possibly mean???



The pedal holes and that arm on the starter are very easy to miss if you get the angled up at the front too high.

If your tub & frame are straight then by using the correct size pad at each body mount your tub will line correctly or extremely close requiring only small increment adjustments at the end of your alignment.
