Engine manufacturer for M151A2

[Paul Singleton]

When I was working we had sidewalk ploughs with Perkins and Caterpillar diesels. The engines were the same except for some sensors and programming. In 2015 when I was still working Caterpillar wouldn’t sell parts for the Perkins and vice-versa. The dealers were unable to look up the engine model and serial numbers unless they were the licensed dealer for the make. We had the same trouble with Mercedes industrial engines. The on-road dealer couldn’t even read the diagnostic engine codes.

Slightly reorienting the conversation, there is a movement in the US for farm equipment buyers to be able to access the coding that runs their pricey tractors, loaders and combines. The big manufacturers are resisting because they will lose the economic advantage of tying a buyer, who is really not much better than a renter, to their servicing contracts. It sucks, but that is how sophisticated some equipment has become and how competitive is the industry. Hmmm? Does anyone remember the old Belarus and Progress tractors on the Prairies? Simple and rugged beyond belief.

Best Jeep engine ever

We had a 151 73 Sigs (Ismalia) DR section that did a lot of runs to Cairo...still it wasn't the favoured truck there.

The engine I've been offered is a wall hanger in a friends shop, and wont be more that beer money. Rad hoses to drive flanges.

Rob - are many parts of this engine compatible with otherm series?

The salvageable stuff is the sending units (oil and water temp), the 60amp alternator (2920-00-909-2483), the coil and cap, and the spark plugs. As well, if the distributor has the electronic ignition, the electronics can be adapted into the M38A1 distributors with a little work. Also, the distributor housing itself can be adapted over for either the M38/M38A1, or for the M37.

The clutch pressure plate is also exchangeable with the M38/M38A1 series.

That is about all I can come up with from the top of my head.

Pardon me for an abreviated message, 3rd time ive typed it on
this GD computer ...
- M151 under rated and getting a bad rap, have been involved in help scrap
200+, biggest issue lousy carburetion- running rich then starving, when sold to
locals military carb is scrapped and an updraft or downdraft installed- then
work just fine
- some design flaws on engine, exh manifold, starter location etc
- have had M151 running on propane using pipe plug ports in the intake
manifold, no issues
- transmission is heavy duty, seems well designed but often criticized, anyone
got horror stories?
- I do have a jeep with an M151 engine and trany attached to original
transfer case. It was an easy fix esp by removing rear transfer case portion
and using the long output shaft. Cut and welded original gear onto centre of
jeep transfer case gear and added 3/4 inch adapter plate. Need to have a
shorter driveshaft made up for the rear. Reposition motor mounts etc.
- Have not had it driving yet.

There was nothing overly heavy duty about those transmissions. Failures seemed to occur starting at around 25000 miles.



When I built my M151A2, I used the best components out of the 30 that I had salvaged. I used a fairly freshly rebuilt transmission which had been rebuilt by Wes-trans out of Winnipeg. It started to fail after less than a thousand miles. On tear down, I found that while everything still fell within specifications, they were all at the outer tolerances, and combined together, it just didn't work out.



The main weaknesses I always found with the M151A2 were all those u-joints (and operators who thought it was somebodies else's job to grease them), and a big weakness was the poorly designed rear suspension hangers. They were basically a 3/8 bolt going through two 1/8" plates. The holes would elongate, causing a dangerous slop in the rear suspension.
