I did the first Unimog repair course run by the Army in 1983 and was still working on them when they went out of service. Very good vehicle.

When did they go out of service? And what replaced them?
@iffracem7 күн бұрын
@@L2SFBC Long post... sorry.. from what I remember (I've had some memory problems lately.. so caveat emptor) AFAIK were still in service when I left in '98 I don't know what superseded them, as I'd converted from mechanic to IT Systems admin in 95 and had long left the army when any replacement happened. When I was involved with them it was in 9tpt Sqn, Townsvile, first unit to get them operationally, and at RAEME training centre, as an instructor. They didn't have those "super singles" when I was in, instead they were issued with Dunlop "Militaires" which were the same basic tyre used on the previous Internationals instead of the lower pressure wide tyres they were designed to have. Why? I have no idea, cost I guess but they were useless and killed 80% of the offroad ability. Yes they had 8 reverse. The same 4 speed/splitter combo gearbox was just reversed. The "Unimog" was supposed to be a universal system that had multiple attachments available, winch, train track stabilisers, forklift, crane, dozer and front end loader attachment. Army only had 1 in 4 with a power take off to use with the winch or crane (1 in 10 had crane IIRC). That winch is weak as, don't try to winch with the rope beyond about 10 degrees either side or the auto fairlead roller will poop itself. I don't think it's the same winch as fitted by Mercedes. Likewise the crane on some (1 in 10) had a weaker crane than Mercedes would have supplied, it struggled to lift and hold 1 tonne in practise... cost cutting or something I suspect The suspension is coil, with "portal axles" that give incredible ground clearance, the nylon bushes of the "torque tube" drive shaft system at the gearbox/transfer case end could cause problems (with the militaire tyres, super singles are softer and should be OK) They used to wear out in a matter of a few thousand K's on a truck constantly loaded, like water tanks (one trip from Townsvile to Karumba via Hughendon on the western cape we had to swap tanks onto 2 different vehicles, then replace the bushes due to that) The brakes are air over hydraulic discs, very good, but the hand brake and caliper piston manual adjusting/retraction system was typical German over engineered and weak. Hopefully the original alternator has been put back on (as the tyres seem to be on yours) The army in it's infinite wisdom had developed it's own alternator (we called it the EDE alternator, after the branch that forced it upon us.) It was supposed to be a one size fits all for all military use, APC's, Trucks.. whatever. Trouble is when fitted to the Unimog it stopped the cab being tilted forward for maintenance. So you had this stupid fart around partially tilting the cab, loosening and sliding the alternator out of the way, then completing the cab tilt... And if you needed to run the engine you had to replace the alternator, which meant you had to go through the same BS just to drop the cab back. You'll notice the RHD version we have has a 90 degree adaptor behind the dash, a shaft that travels across under the dash to the left side of the dash, than another 90 degree adaptor that joins it up to the original LHD shaft. Works, but you'll find that traveling any distance at around highway speed (good luck with that.. 80-90kph is it's realistic top) it's a hell of a lot easier to have only one hand on the wheel keeping a slight "preload" to one side or the other .. two hands you end up weaving all over the place. You'll find a can reach under the dash and easily steer the thing with one hand by twisting that shaft.... a dirty trick to play on an unsuspecting driver..... so a friend tells me ;-) Great vehicles, stuffed up in some regards by the Army, but if returned to their original state (tyres, alternator etc) will serve you well for a very long time. The only problems we had at 9TPT were the tyres, alternator and sometimes disc brake adjuster and the headlights were weak.. very weak to the point of dangerous .. everything else was near bullet proof. Except that one they drowned in an amphibious landing exercise... that one was never right afterwards.

The gear boxes have all sorts of configurations in terms of 'working gears' and PTO's (there are both high and low speed PTO variants). I think some arrangements on the gearbox and working gear sets achieve essentially 4 levels of reduction (with 2 of those being available in the standard gearbox). There were also some aftermarket overdrives made at various stages from Class and Perkins Engineering. Diff gears are available in all sorts of combo's, mostly for people looking to run different tyre sizes and reduce RPM's at higher highway speeds.

Drove them in the’80’s did my drivers course on them and then posted to a transport unit that had a troop of them. Interestingly I drove the last of the International MK5/F1’s UBRE’s in the 1990’s, so I drove the ‘mog first then the Mk 5! And as others have said, like chalk and cheese. I also got to drive the Unimog with hi speed diffs, it could do over 130 unloaded! I always thought the Unimog was a great truck, I always said the Unimog did everything with technology (at the time) while its companion the 6x6 Mack used brute force! Like the Mk 5 really.

I have driven the AMT Isuzu. It is slow to respond at times, but can easily be manually operated. I think I'd prefer it over the manual as it's less work, and simple enough to manually shift eg when approaching a hill. Like most AMTs, you get to learn how and when it'll shift up/down. Converting a Fuso is expensive.

@L2SFBC The great thing is that in converting one of these to an expedition truck, you are not going to worry about overstressing the thing. The morass of shattered CV joints seen in struggling Japanese 4x4 trucks venturing off road do not feature in the Unimog World. Look also at the feeble transfer box in an Iveco Daily and compare with Unimog components and there is only one winner. With zero electronics and on the move 4x4 and difflock engagement to boot. Apart from the magnificence of optional CTIS and the Claas splitter overdrive gearbox apparently developed for the 6x6 version doing missile launcher duties. Not sure if the ADF variants have the venerable OM352 or later OM366LA motor, but either one is more reliable than your heartbeat.
