Unimog Club UK

Hi,

You have what I assume is an ex rienbrau (if that's spelt correctly) Unimog, although the company is no longer called this, but i cant remember what they're called now. It was origionally a crew cab, hence the butchery that has been done, with some effort you can tidy this up, but you might be better trying to find a good used cab

As for your questions:

PTO
This is just a standard 540 PTO

The water pump is knackered, eBay and vos put them from £150-200 does anyone do a rebuild kit or has anyone replaced the bearings?

This is a reasonable price if genuine

Where is the best place to get a workshop manual and how much are we looking at?
Keep scouring ebay, or contact some dealers

Filters, does anyone have a list of filters and cross references?
I don't have any cross references, but many of the filters are MANN

Diesel pipes, I have two returns, leak offs coming back to the NST of the diesel tank, these t into each other here before dropping through a banjo into the tank, do they need to meet this far back or can the join at the engine and run one pipe back? I also have a sedimenter in the feed pipe is this standard?
Yes you can t these next to the engine, one is a bleed off for the injectors.
This is a standard filter, remove it, clean it, and if necessary replace

Cab mounts (rubbers) these are kaput and combined with a religious cab it bangs on the deisel tank, are they a fortune, available or shall I make my own?
Not sure, best thing to do is contact dealers

Air pipes, the rear body was a tree spade and gassed off melting some air pipes in the process, is there a few common or standard sizes used or do they all differ? The small 6mm pipe looks very thick walled is this just old eighties factory pipe and times have moved on to the newer thin wall stuff?
The sizes vary, most common is 8mm on most 406's according to moose. we also assume that the 6mm is just old technology.

Headlights, they look like standard 7". Is his so? I'll knock some out the Landy if so.

Unimogs have the side lights mounted in the bowl, strip the light apart to see how they work, that's the main difference.

I have three levers and two air switches in the cab, no splitter? Is this normal?
one of the air switches could be an air brake tester according to moose.
the others are forward/reverse, PTO, main gear lever, and 2x2/4x4/difflock
You won't have a splitter as you don't have the cascade box, follow this link

Is this the 4wd linkage? Can I return it back to a lever rated than pneumatic operation? Anyone have pics of the linkage or an old lever?
Yes it is, and yes you can I'll get some pics as soon as i can of the linkage, they'll be of the early system, which uses notches to lock the lever in place, meaning you have to knock the lever down.

I want to splice a pcl coupling into the air tank so at first I can pressure it up to check for leaks without the engine running and then swap to air tyres ect, where is the best place to do this? I was thinking into the tank but will damage the unloaded or evaporater?

I don't know

Just exactly what oil does the gearbox and axles/hubs take? I'm guessing EP90?
Already been answered, but you can also use genuine merc semi-synthetic oil in the hubs and diffs

Cheers, Brian
