Diesel in a Magnum 8x8

[Rudy_Magnum]

Thought this would probably be the place to put this post. I bought a machine that needs a fair amount of work. All axle bearings and seals, just to start with. But, the engine (Kohler M18) hasn't been taken care of properly. There is just over 1000 hours on it, and it smokes like is a 2 stroke, and has a lack of power. The guy I got it from said its just stuck rings from sitting for a long time. I tend not to believe him.

So, to the point of the story. I've been looking around for different options, and found a guy that sells off old thermoking reefers. So I paid him a visit yesterday. He has one that has a yanmar 3 cylinder that's rated around 20hp. Perfect! Its physically smaller than the magnum, so it will fit in no problem. I figure I can sell, or scrap the rest of the reefer to get back a bit of money and have a pretty cheap option for repower. That, and I love little yanmars!!

So, my question to the masses is, does anyone know any information on doing this, before I get my arms greasy up to my elbows? Engine is a TK3.88S. TK= thermoking, 3= 3 cyl, .88= .879 litres displacement, and I don't know what the "S" means. From what I've found, these do have the "throttle" lever on the side of the injector pump, just need to take off the solenoid that controls it. Its likely governed at 2200rpm, so that will need to be turned up. Other than that, its just gonna be some fabricating, and drinking a few beers.

Any input (good or bad) is very welcome!

Have done a bit of research in the last few days. Found an actual manual for a TK3.88. From what is in there, I figure it will have all the adjustments needed to turn up the speed. I compared the pictures in the manual to the yanmar in my 332 lawnmower, and the only thing different is that it does not have the fuel shut off arm. I would imagine that would be controlled by the throttle arm. It has the same Bosch injection pump, with the same setup for the fuel control rack. I don't see any reason why this wouldn't work.

I have sent an email to a local refer transport company to see if I can get one a little cheaper. The price of free is always best. The ones I looked at on Saturday were gonna be $750. But, I could recoup some of the cost by selling off or scrapping the rest of the unit. We shall see. Will keep you guy posted as I figure more stuff out.

I've gotta say there are a few diesel swaps that have been done and shown here. I'd do it if I was you, as I just did a 2cyl 670cc Kubota in my Muscateer. You can check out my thread in other AATV section.

The PTO side of things and the clutching could be an issue. You may want to investigate if you can run it up to 3600 or so RPM safely.

Compared to the 12hp I had there is night and day difference.

Good luck and post lots of pictures

A little more looking around and I came up with that a 3TNA72 is the same 879cc engine as the TK3.88. Good to know, as they were a VERY common engine in John Deeres and other machines. Found a complete governor assembly for not a bad price.

Riotwarrior, if I can convince the wife that this is the way to go, I'll have that reefer in the truck the next day and be doing heart surgery. Will keep you guys up to date.

Wifey said that she trusts my decisions on this matter. Took some explaining, but I think that is the green light! Woot!!! Looks like there will be another diesel project going on here!

I beefed up my ramps last night. They're rated for 1000lbs, from princess auto, so not the best of quality. We bent them loading the machine last time. So, I bent them straight and put some reinforcements in. Will need the extra strength. The yanmar is 100 lbs heavier, apparently.

Sounds great..

BTW, seeing you said PRINCESS AUTO...not Harbour Freight...Where bouts you located.

I'm just outside of Kitchener, Ontario (birthplace of the Argo!).

Ahh...nice, out here in BC in or near the only Desert in Canada gets warm here in summer ugh...we had 107 deg in shade a few weeks ago....ugh!

Hey NEED pictures this thread is useless without them !!!!! LOL

What is the proper way of posting pics around here? Don't have too many pics yet. Machine is at my buddy's place. Would be here, but selling our place, and can't have it all ripped apart here. We are set to start (hopefully) this weekend.

Wel there is an instructional on here somewhere, however I just upload my images to Photobucket and some album I created, then copy the IMG code from the picture into the thread and you get FULL size images not postage stamp sized ones ...

I like big pictures myself.

Here is how to upload photos to the forum: http://www.6x6world.com/forums/6x6-w...-pictures.html You can also do like riotwarrior mentioned.

As do I. Have photo bucket. Have to see if I can remember the password now. Waiting for guy to show up for the reefer. Getting excited like a kid in a candy store!!!

[Rudy_Magnum]

Picked up the reefer. Started inspecting. Didnt get too far. Made of mostly aluminum and copper, so should be able to get good scrap value. Slight disappointment, yanmar seems to be stuck... The guy I got it from said if I had any problems to bring it back and he'll give me another one. Hope he stands good for it. I tried a wrench on the crank, but no dice. I dont think it has that much compression.

[Rudy_Magnum]

Going at lunch today to change out reefer. Hopefully the other one he has is better.

Anyway, some eye candy.

After I got it home:

Nice...very nice. That should make that machine a monster, too bad yer not closer we could go do some wheeling once we get our units up n running ROFL.
