A Turbodiesel Conversion for the Unimog-S:
Cab Installation and Modification
Now the engine was installed in the cab and everything that I could think of to do BEFORE the cab installation was done. I couldn't put it off any longer. I'd heard lots of different rumors from plenty of people, so the only was to find out was to plunge in. I picked up the cab with one of our loaders and pulled the chassis underneath it. The first attempt just didn't make it. There was no way I could sit the cab over the intake/exhaust manifold and turbo without cutting things up. It's important to note here that ALL of the removable panels from the cab floor were gone at this point.
To prevent cutting in a "best guess" fashion, I decided to remove the manifolds and turbo and sit the cab on like that. The plan was to then remove just enough metal to allow space for turbo installation and removal without cab removal. It worked! I got the cab installed with little trouble...

On the previous page, I mentioned "rubber blocks for cab." These are rubber cab mounts that provide about an inch of cab lift. With this minimal lift, it doesn't look like the steering column will need to be moved. You need a total of six blocks, two for the front center mount, and two for each rear mount. Here's the front mount...
There were now some space issues that had to be dealt with. The engine was pushing the cab over to the driver's side slightly, as the driver's floor was hitting the front engine mount. The rear manifold studs cleared the passenger-side sheet metal with nothing to spare. Using plasma, an air reciprocating saw, an air cut-off saw, and a Sawz-all, I modified the floor to get the clearance I needed...
In the photo above, you can also see a slight interference with the hand-operated lift pump on the side of the injection pump. After modifying and installing the lower left engine cover, I was left with this...
During a chat with Rob Pickering, he offered a simple remedy for the clearance problem. If I relocated the oil filter and the lift pump bolted to the side of the injection pump, I could use entirely stock lower and upper left-side engine covers.
