4.2L industrial diesel info

I’m looking for information about this 4.2L. She needs to be rebuilt. I’ve found rebuilding kit I just need all the torque specs. This engine is in my air compressor.

i think what you may have is a Ford/Lehman 80 diesel engine. 254 cubic inches, and called the Lehman 80 because it was made by British Ford engine maker Lehman and making 80 HP.

Thanks for the info. That’s what it is now knowing this I better double check rebuild kit I’ve been eyeing. It is a ford block has the logo embossed below the injection pump.
