Sorry for the late reply.
It is one of the standard diesel units
- it seems to run fine though and does not appear to suffer from any lack of power, well not that I've noticed anyway.
Nice, I will try!
Wow your restoration is certainly comprehensive! I like how it's all starting to look now. I don't mean to sound rood but it sounds like your truck was in a bad way before for its age, it must have been quite badly neglected before you owned it. Mine is as you know slightly older than yours by two years but it does not seem to require the same attention yours is having, all air lines etc look quite healthy and the cab is actually quite sound under the rough paint and odd dent, it's just as well really as I don't think I could be bothered doing all those air hoses unless I really had to - I'm too lazy
Well, it was a nice runner in quite acceptable shape apart from the cab. Just a little neglected. I think noone really cared for it for a long time. There was a thick layer of dirt and mud in the water separator, and water in the main air tank. Not running every now and then is a real killer for any vehicle.
Because it didnt run often enough the fuel lines and tanks rotted away, and the air system partially rusted away from the inside.
Good side is the engine is brand new, you can tell by the belts and pulleys
Either way, dont be fooled. The restauration thing got a little ouf of hand. The air system wasn't all bad, but I replaced it all just to be sure. The brake valve worked great, I just serviced it so I feel better. The paint is just for prettyness, not really needed as most of the original green is still there under the dirt. The clutch worked great and smooth but I renewed the lines cause they were leaking a tiny bit. All the diff locks worked, I just cleaned and greased them cause I had to take them apart to put in new air fittings.
Lastly, doing an almost frame-offjob like this means I get to know the truck inside out. That's going to be a major plus when I have to service it next time, or when something breaks on the road.
BTW the unit in your last post looks like the low air pressure buzzer.
I thought the buzzer was on the other side (the black box thingy). But thanks, if I get an annoying buzzer Ill clip the wire again.
Oh also, have you found anywhere that are good on replacement tyres for the 813?
Fridgefreezer PM'ed me about a source for tires in Germany, I havent followed up on that one yet, but feel free (and share info!).
