Default Ajax DP 160 Specifications?

I have found what I believe to be an Ajax DP 160.

anybody have the specifications on this engine? Weight?

Curious to the value of these engines. Was supposedly rebuilt 10 years ago but never ran. Looks like it does NOT have a clutch but does have a pulley for a cog belt. It was possibly coupled to a compressor at one time.

DP 160, twin cylinder. 11" bore, 14" stroke. I have Ajax manuals and books but they do not mention weight. As for the value, It might be worth something to the right guy. However, they don't pass many clean air requirements and have become boat anchors

If you find out what it weighs, let us know! Is it a 2 or 4 stroke engine?

All Ajax engines that I have seen are two stroke. I’m not aware of any four stroke.

It should be over 10,000 pounds as my 7 1/2 x 10 single is about 5k.

I assumed it was a 2 stroke, since all the ones I have seen are 2 stoke natural or well head gas.

If it is under 20,000lb I can haul it on my duel tandem but loading it might be a different story.

Big oil field engines don't seem to be worth much.
