hi everyone and sorry if this has been asked many times before (i have used the search but didnt find anything)and sorry for firing straight into how do i,:newbie: ive got a 93 427 (u1200) with a sick motor, now ive pulled from a merc 1617 truck a very healthy 366a which i have driven and tested well,am i going to come across any stumbling blocks fitting this motor to the unimog,i know the sump and turbo/manifold need to be swapped but what about the pump as it looks quite fat on the end and not sure if itll clear shock mount,if i need to keep the original unimog pump can it be made to give the trucks 170 bhp,apart from that is it a straight forward swap?thanks in advance cj:thumbsup:

Mark Mitchell in San Diego has done this adaptation. Here are a couple of photos, but Mark knows all of the ins and outs.

They had to cut and bend the right front shock mount for clearance problems, but the bus (or truck) Injection pump has worked out V. well.

The shock mount base was cut, bent and re-welded, it took some half hour and ingenuity to bend the mount after cutting the notch with the plasma cutter.
The truck IP will give you a better mileage and road manners, you do not need the tractor (unimog) IP unless you need your mog for work.
You will need a very large impact wrench to remove the large nut that holds the dented wheel.

So, how would the truck governor cope with running a PTO?Would that almost render the PTO useless given that it would not increase the fuelling according to load?I'm not saying this would be the case here as I don't even know if the o/p has a PTO set up on his U1200, but it was something I was thinking about when I was investigating I/Ps for my U1000 upgrade.Would it not be possible to put the pump from the original Mog OM352 or is that part of the sick issue??

Basically swapping a Unimog om366A for a truck om366A is nothing more than swooping ancillaries like the turbo/manifold + oil cooler plate if the currant permanent filter interferes with the Unimog turbo/manifold etc, etc. though you may find that the truck engine doesn’t have a camshaft driven air compressor on the block but an auxiliary/high capacity belt driven one that may have to be moved into the Unimog position rather than the truck position.

The Unimog IP can be upped to 170hp but it will need a few parts changed internally + internal settings changed which is best done by an IP specialist, but you may well find the IP is the same body as the truck one so it will just be a case of getting the IP specialist to swoop the governors.

Personally I don’t mind the Unimog load governor, I am happy with the >13.5mpg (UK gallons = 4.54609188L) I get on runs with my Unimog, which in part comes from the strengths of the load governor fitted to Unimog’s in that they will back-off the fuelling once speed is reached then will maintain speed up & down modest road height changes without you having to move your foot like you would on a normal vehicle.

righ,its in and runs now,very easy to do,first strip the donor motor down to a long block,we kept the truck inj pump to keep it all as close to the 174hp it made in the truck,next swap the lift pump from the mog to the truck inj pump as the truck one didnt match up,next lift both motors and swap sumps and oil pumps over,after this all the mog parts will bolt up to make a running unit,we didnt have to touch the off side shock mount as first thought and had about 2cm of clearance when bolted back in,only issue was the little air device to pull the pump to stop the motor was different so had to fab a new throttle linkage and incorporate the truck air stop,so all in all very happy,out with the tired 125bhp tired motor in with 174 truck motor with more revs too,:)

So basically it's just swap all the external ancilliaries over from the old block to the new one?

what about water pump,alternator etc? and is the clutch/flywheel the same too?

good tech thread! :thumbsup:

i swapped all the parts from the mog motor to the truck motor apart from the inj pump,the water pump looked mog specific,so did the front crank pulley and all 5 belts,wasnt going to take a chance on the flywheel so swapped that out aswell,did notice that the turbo from the mog (k27) was the exact same unit on the truck just had to undo the 13mm bolts and swivel it around to line up as it looked a much newer unit than the mogs,just a huge overall service then its going to be pulling silage trailers this year,:D.

Apparently, the term (and method of storage) has different meanings depending on where on the planet it is being used:


silage |ˈsīlij|
noun
grass or other green fodder compacted and stored in airtight conditions, typically in a silo, without first being dried, and used as animal feed in the winter.
verb [ intrans. ] [often as n. ] ( silaging)
make silage.
• [ trans. ] preserve (grass and other green fodder) as silage.
ORIGIN late 19th cent.: alteration of ensilage , influenced by silo .

Silage - Wikipedia, the free encyclopedia


"Silage is made either by placing cut green vegetation in a silo, or by piling it in a large heap covered with plastic sheet, or by wrapping large bales in plastic film."


"Using Different Types of Silos
Structures varying from silopress bags to large bunker silos are found in Florida. The tower or upright silo is less popular on large dairies due to limited storage capacity it offers for feeding large numbers of cows.

Tower Silos - very little seepage occurs from forage ensiled with less than 70% moisture in upright silos. Losses reported in dry matter have normally varied from 8 to 20%. The losses reported from properly harvested forages stored in gas tight silos are usually less than 10%. Greater losses are easily encountered where packing and sealing are poor.

Bunker and Trench Silos - losses in horizontal silos have been observed as high as 30 to 50% in unsealed or poorly sealed silos. In recent years, the applying of plastic film has greatly reduced storage losses. Limited work indicates that low-moisture silage (65-75%) may be preserved at efficiencies approaching those found in conventional silos. Average losses from 70% moisture forage stored in well-packed bunker sealed silos is about l0-20% but somewhat higher in unsealed bunker silos."

I am no farmer, but a big fan of farmers. And now, some breakfast !
