Industrial Chrysler 6

[garbagestate 44]

Hello,

I may have a chance to obtain a rebuilt ind. flathead 6. It would be my intention to mate it to an M-6 fluid drive which, from reading several posts, has 8 bolts between the fluid coupling and crankshaft flange as well as being a little thicker. I don't know what the displacement is on the industrial motor beyond it being a 25 inch block (probably either a 251 or a 265) Would it be a dumb idea to fool around with this thing without finding out what the crank flange looks like? Also, if I got it anyway, how practical would it be to swap out the crank on my 251 if it became necessary to make this whole thing work? Whew! this is tough without a spell checker. Thanks in advance,

John

I would believe that being its a log block and longblocks were designed to accomodate the heavier fluid drive unit and trans, that the industrial engine would have a cranks shaft that would be compatable. It doesn't seem that Chrysler would engineer a lighter duty crank for that engine. If that not the case your crank should swap in if needed.

Was this a stationary engine or in a HD vehicle of some sort?

It has a crane application of some kind so I cant say whether it powered a hydraulic system or whether it moved the crane itself. I woukd assume the former since things like self propelled cranes usually have pretty beefy motors but I don't know yet.

The engine number on the upper left front corner, will tell you if this engine was really an industrial from the factory or a rebuilt engine, being that you are in the USA , will likely be a 251 or 265, if this were a Canadian Long block, it could have been a 218,228,251,265, and some others.....Fred

I have a manual that I bought from Vintage Power Wagons titled "Chrysler Six Cylinder Industrial Engines".

I says there should be a plate on the manifold side of the block that should tell you which model it is. If you find that, I can give you some specs on it.

It looks like some would have been hooked up to a gear drive (4 bolt crank flange) and some to a fluid drive (8 bolt)

Models are 5, 5A, 6, 6A, 7, 7A, 8 and 8A.

You might want to invest in one of these manuals, I don't think it was very expensive.

I have hever seen a long block engine with a 4 bolt crankshaft. But there are a lot of things that I have not seen. Can one of our Caniadian friends tell us if there was a 4 bolt crankshift used in the long block Caniadian engines in Plymouth cars or other non fluid drive cars or trucks?

Never seen one, but like you there's alot I've never seen.

I have an industrial engine that was in a snowblower with the 8 bolt crank and I have 3 other blocks from Canadian cars, all with 8 bolts as well as my nephews Fargo truck engine from a 1/2 ton has the 8 bolt crank. The original engine from the Fargo 3 ton also has 8 bolts. All these are 25 inch blocks.

In the specs of the industrial manual... 5 & 5A are217.8 ci, 6 & 6A are 230.2 ci, 7 & 7A are 236.6 ci and 8 & 8A are 250.6 ci.

So it looks like they made both the short block and long block in industrial engines.
