Detroit Diesel 2-71 engine overhaul and start

Detroit Diesel 2-71 engine overhaul and start. 1949 Allis Chalmers HD5 Dozer engine brought back to life. Rebuilt by Continental Engine Rebuilders of Regina SK. Canada. Engine was brought in to us with a spun rod bearing which damaged crankshaft and connecting rod.

[@jshenderson8147]

Rebuilt one when I was in the Coast Guard- it drove an 850 psi starting air compressor. Enjoyed hearing one again. Thanks for sharing

[@nester318]

Wow even the small Detroit's sound awesome. Great work I am sure that engine will last another 40 years.

[@andrewludlam2565]

First time seeing a 2 cyl Detroit, Worked on many V 6 8 12 and 16 loved em

[@jhomrich89]

These and the 3 cylinder detroits were commonly used in industrial construction equipment, refrigeration cars for freight trains, generators ect not an on road bus or truck engine like you would typically see a detroit in.

Wish I knew about you guys when my 2-71 blew up. Took the boys at Harper 2 weeks to get pistons and sleeves and another week to rebuild it. But 12 years later its still going.

[@georgerenton965]

My first job was working at Harpers back in 69. What a life’s education that was for a 14 year old. That’s when I fell in love with Cabover Kenworth’s. Owned two of them, drove one for 26 years.

When I lived in Galveston and worked for Republic Parts, one of our customers had a 72 GMC pickup he installed a 2-71 in. Drove it for years around the island.

[@rickdickerson1204]

Wow! A 2-71 in a pickup! That would be great! :)

[@Romans--bo7br]

How did that work for him in a pick-up?.... couldn't have been much fun to drive - they don't have limiting speed type governors for them, because they were never intended for any kind of automotive applications. The 3-71 would work though, because they did have limiting speed governors for them as they were used in numerous types of smaller road equipment machines... ie; smaller road graders, "steam" rollers, paving machines, etc, etc.

Get little yanmar clone on ebay

[@Bearthedancingman]

I want to stick one of these in a single seat road going car looking a little like 1920s racers with a bit of "dieselpunk" design flair with the engine behind the driver. It doesn't need to be fast. And the 920# weight is fine too. Just sound good and be fun to drive. I'm planning to use a 2+2+2 transfer gearbox I have from an old piece of farm equipment. (I'm not sure what the machine did to be honest, I helped the farmer take it apart for scrap and the gearbox was good so he let me keep it as payment for my work. I've had it for years) The two gears are sequential (N - 1st - 2nd) and then you pull the lever back to neutral & push a second lever forward to the next detent to change to the next pair of gears. Like a mini twin stick. Complicated, but would be a hoot to drive around. If that doesn't work, I'll use a beefed up VW bus transaxle.

@@hunter7476 unless you were talking about this design wouldn't run without a blower, there is plenty of diesels that have no turbos and no blowers.

[@rayg9069]

@@matthewhoffman9242 You do realise the GM is a two stroke engine? It's closer to a lawn mower in design than an Isuzu. They will not run without a blower to push fresh air into the cylinders, they don't have a reed valve crankcase like smaller engines.

While getting around town & loads in the bed were just fine, pulling grades & such, highlighted its severe lack of power...We got "stuck" trying to ascend a moderately steep ramp into a garbage-dump after dumping our refuse...it was quite the pathetic sight seeing a Ford trying so hard to climb such a mediocre grade....just plain ran out of power.

[@travishanson166]

With the right gearing this would power an automobile just fine. It has 3x the torque of most 4 cylinder gas motors, but only has about 600 useful rpm in the power band. Whereas a small gas motor will utilize 1200 to 2200 rpm for acceleration in the power band.

got a question on this motor if you can help

[@ekpregsk]

Lets see if we can help you. What is your question?

[@brandynnboren3580]

I have a 1950s ac hd5g crawler loader. It has a 2-71 in it for a motor. There is this long tube about 2 inches wide coming from the bellhousing/transmission area and i can see it in your video. That is the transmission fluid fill spot right? Where/how do i add engine oil? I can only find the dipstick but no fill point. Is the engine oil and transmission the same fluid? Thanks

[@ekpregsk]

No, that 2" tube is your engine oil fill. I know it looks like it is going to the bell housing but does not. You see the flywheel open there and it is a dry bell housing. The transmission is a separate lube system. Not sure what fluid they use in the trans.

[@brandynnboren3580]

appreciate the help how much oil does it take? where could i get a new oil filter? do you know where i might be able to get a new fan, belts, and radiator? are things able to be swapped over to alternators or are the generators better? thanks again

[@ekpregsk]

We used 6 Quarts of oil. the oil filter we used was a Wix brand # 51010. The fan belt we used was Dayco # 22620. Pay attention to your system for 6 volt or 12 volt. If it is a 12 volt then you could switch to an alternator (best with a built in regulator).

[@andreborowski4954]

And it can run in both directions, right? No need of a back gear..he. he.... I remember such Engines driving Fire Pumps. They had to run in a proper direction to achieve the pump efficiency.

[@TugboatMatt]

Wrong. In order to change the engines rotation there are a number of parts that need to be changed. The Camshaft, starter, fuel pump, oil pump and water pump. The idler gear location is also changed. Yes they can start (bump start) in reverse but they will tear themselves apart in a short time
