Engine manufacturer for M151A2

[rob love]

They were good engines....much longer life than the M38A1 engines, but man they were uneven. The vibrations from the engine would cause the mirrors to shake so bad you couldn't see out them.

LETE actually did a project to install one of these engines into the M38A1. Adapters were made, the engine installed and tested, then everything packed up into a crate and into the warehouse.

I did not know that. AFAIK that engine was the Ford L142 - a 4-cylinder 2,320 cc. unit delivering 72 bhp. at 4,000 rpm. Over the course of it's long production run, most likely the engine was built by other manufacturers too, as was the jeep itself. During 1964-1983, production contracts of the M151A2 were awarded to Ford, Kaiser Jeep and the AM General Corporation (of Wayne, Michigan, U.S.A.), while bodies were built both by Fruehauf and Budd .

Read my webpage on the M151-series (a bit outdated as there is a load of broken links, but still relevant): http://www.mapleleafup.nl/fordm151/

Is there a link to the manual, aformentioned?

[rob love]

The parts manual is TM 9-2320-218-20P . A quick google of that number leads to several places where the manual can be downloaded.

Unless Terry is talking about a different manual....

Here's one on identification

and this is the illustrated parts manual.

One thing that interests me (as a matter of pure engineering interoperability) is this engine has both gasoline and natural gas variants. Although I don't plan to lug around a big blue tank for fuel especially in cold Canada, it is intriguing nonetheless.

Other than changes to the carburation, the engine is the same. Any petrol engine can run on a mixture of air and natural gas, LPG (or petrol). It's all about hydrocarbons...

Thanks Terry

I don't have a 151, but have the option to buy an engine package....don't even know why I want it, but...

Charlie, don’t overpay. M151 engines are a dime a dozen, especially in the US

I took apart 30 M151A2s back in 87. I would sell off complete running powerpacks for $125. Otherwise, I would sell the alternator and the distributor components and make just as much. I still see the odd powerpack show up from somebodies shed for $500.

Re alternate fuel sources, propane is very hard on valves and seats....some engines more than others. I got to experience a lot of that first hand when the military tried to run propane vehicles back in the 80s. It was definitely not the right fuel for this climate, and not the right fuel for multiple users.

Petrol engines can be duel fueled but like anything, an engine functions better when designed and built for a specific fuel. I remember seeing a new Ford crate engine (D series Ford- English commercial) in the parts department of the local Ford dealership. It was a dedicated gas engine. Likely the valves, guides, maybe the head? and pistons were different. Essentially a diesel engine re speced for LPG.
At one stage here in N.Z. possibly 15 percent of cars on the road had been converted to duel fuel, either CNG or LPG with petrol. It was a whole new industry, which died as quickly as it started.

On the Caterpillar thing. Have they bought Perkins?
When I was working in Kalgoorlie (Australia) We had small diesels that were black and labeled "Perkins" and the yellow ones were labelled "Caterpillar" they were all the same and I was told Cat had bought Perkins?
