detroit diesel question

MikeO-WI · Sep 28, 2017

I have a line on a 50 series Detroit diesel that was purchased new and has never been installed for 13 years. May consider it for an Oliver implant or simply as an irrigation engine. My biggest concern is what issues might it have for sitting so long. Already have a 4-53 in one Oliver. This is a non-emissions 2 stroke from the early 2000 era. Engine has remained sealed. Any insights to the the non-use question or installing in possibly a 1955 chassis would be appreciated.

I can't comment on if it will turn over, but your looking at an engine that's almost twice the size of the 2 stroke Detroit engine that the 1950 saw. But if there's a will, there's a way. If I recall correctly, it's an inline. Good luck, that would make an interesting tractor. You might be better served with the cummins repowers since it would be less fabrication work.

50 Series is a 4 cylinder 60 Series.

As has been mentioned a Series 50 is a 4 cylinder 4 stroke Detroit. You should call A Detroit dealer and ask them for a bulletin that gives the mounting dimensions for the engine.

You're not going to fit a 4-53 into a Waukesha tub without some magic. Maybe into a Perkins tub.

One thing about Detroits that have been sitting is to make sure the rack is free! Keep a board nearby to suffocate it if it takes off. Other than the common things to all engines that have been sitting (check oil for water, mice, etc...). I'd check if all the injector plungers move freely too. You might find one that sticks down after you depress it. If so, just replace it, they're cheap, available, and easier than rebuilding.

Thanks for the info on the 53 series Detroit, but the one I am looking at is a 50 series which is a different engine. 4 stroke. I do have a tub from a 2255 that I could use.

Ohhh! Ha! I was thinking 50-series Oliver (as in 1950) with a Detroit.

So, the 50-series Detroit I think was a joint deal with John Deere and Detroit. Might see if the JD group has some details on that. My understanding is it's a 60-series with 2 cylinders lopped off, but that may not be the case and any measurements may not be the same. If the width is the same, the details might be here... https://www.powerlinecomponents.com/literature/detroit_diesel/ddc_drawings.htm

Good luck! That would be a very interesting swap. You'll have to post pictures if it happens!

With the power ratings I have found for that engine you, if you do decide to drop it in a tractor your not going to want to go any smaller than a 1955 that's for sure. 19's used wider bull gears and they had a support bearing that pushed on the back side of the ring gear to keep it from deflecting under high torque loads. 1855's and smaller didn't have that back up bearing, I've seen the results of a 180 horse 5.9 Cummins completely destroying a 1855 ring and pinion and related bearings because of that exact reason, and probably a little ignorance on the part of the owner by trying to pull implements that were meant for a 180 horse tractor instead of just pulling 110 horse implements a gear faster.

Never felt with a 50 but many 60s. Sitting didn't USUALLY hurt one. Its a fully electronic engine so you're going to be doing a lot of wiring.
