Hough 60 payloader

[756puller]

Guy called me up to come look at his payloader engine that's getting coolant in the oil pan.  What are some of the places the coolant can get into the oil pan on a d-282 engine?

[snoshoe]

Other than a cracked casting. I think you're pretty much limited to a head gasket or oil cooler.

Alright, I was kinda figuring get a used motor, rebuild and swap them. But I'm starting to think that I might as well tear down the current engine in it and that fix that one if I can find the obvious problem

I would start with a radiator pressure test with pan off.

Core plugs under the valve cover ?

or the oil cooler -- remove and wash it out
then rig up air and submerge in a bucket of water

Are we sure it is a Hough H60 and or D282? My literature doesn't show a D-282 coming in an H-60. Not to say someone hasn't done some swapping. The D-282 did come in a Hough H30B, H50B, and H50C. Depending on which H60 as there was an H60, H60B, H60C, and an H60E all with different engines, none being D-282. 

Not trying to be argumentative but the D-282 looks to be a dry sleeve engine whereas some of the other possibilities are not. Wanted to be sure we are talking about the right animal.

It sure looked like a 282 with the injection pump on the right side of engine and thought the decals said h-60

[Binderoid]

So what does the literature say about what engine was the H60 equipped with?

[Dirt_Floor_Poor]

Wasn’t there a larger displacement diesel that was just parent bore and did not use the dry sleeves of the 282? D301 I think.

Yes D301.

According to the sales literature for a H60 (not a H60B, H60C, or H60E) the engine options were an IH gas G-372, Cummins JF-6C1, or Detroit 3-71.  That's why I ask.

What is a  Cummins JF-6C1?

I am lucky enough to have a 1968 Hough with a 358 V6 cummins .   It needs  a head  gasket as it is putting  pressure in the radiator.

I had a D282 that was getting coolant in the oil and It had a cracked cylinder sleeve. It would also get pressure in the radiator if run above half throttle.

D-282 is a dry sleeve engine
that crack went all the way thru
Those can be repaired by boring and a custom sleeve

It's a C-160 with  two cylinders sawed off.

The crack did not go all the way through but let pressure through above half throttle and pushed under the head gasket and would seep coolant back the other way when shut off. I replaced the sleeve and all is well now for many years.

Did swing back by and looked at engine serial number, would this number be early or late? It is in an h-60 also

Late - heavy press fit sleeves.
