Default Lorain Engine

I went on vacation for nine days and when I came back home I found this engine in front of my shop. I guess a scrap guy left it for me. I'm sure he will come by in a few days to collect scrap money. I have never seen a Lorain and do not know anything about them.
The tag reads ser#542, Bore 7.5,
Stroke 8, 21 hp, made by the White Roth Machine Corp, Lorain Ohio.
This is a 2 cycle gas engine with a cross head. ensign carb and a mechanical single feed oiler. This engine is very complete and shouldn't take much to get running.
Does anyone have any history on the company? I'm guessing the years on this to be late 40's or early 50's?

Most of us have a hard time finding engines and you have people dropping them off at your door step. You must be doing something right.

I have one like that too, a guy gave it to us just for hauling it off. My radiator is gone though.

I just picked one up in Colorado a few weeks ago. I went to an oil field equipment dealer for some FM ZC 503 flywheels for my 15 hp Z, saw the Lorain, and had to have it. It was missing the ignition, exhaust flange, clutch, and had some broken lubricator parts. I have found everything but the clutch now. I will probably never find a clutch, but that's ok. It will run without that. It has good compression and feels like all the bearings are good. I hope to have it running by next summer. It will only take that long because I'm getting a 25 hp Superior this week, and it comes first.

BTW, it is a 7.8x8 bore and stroke and is rated at 24 hp and 600 rpm. I doubt it will ever see more than 300 as long as I own it though.

I dont know any of the company history but they are a very well built engine. As far as I know they are the only 2 cycle oilfield engine with a replaceable cylinder liner. Too bad Ajax never did this

Thanks for all the replies guys. I was really behind yesterday since I was gone for 9 days, but I couldn't stand it and just had to turn a few bolts on the Lorain. Inside the crankcase is real clean and oily. Took the head off and didn't look to bad there either. I took the exhaust flange off and there is where the piston is stuck. Soaked it with penetrating oil overnight and will see if anything moves today if I get time.

dirtbikepilot, where does the line from the oiler go? That seems to be the only thing missing on mine.
Thanks

It goes into the top of the cylinder, just like on the smaller Ajax engines.

Well I finally got a little time to work on the Lorain today. The piston has been soaking since Tuesday and still seems to be stuck as a few blows from the sledge and oak block didn't budge it. I was hopeing it was not stuck bad as most everything is still oily in the crankcase. Looks like a little more soaking time and some hydraulic force may be needed.
The scrap guy that dropped the engine off came by to see if I wanted the engine. He figured I did as I was working on it. I had to pay him 300.00 as long iron is bringing 5.50 per 100lbs. I told him to keep bringing all engines with flywheels and I would take them all.

I am not going to Grandbury as my son is playing in a tournement in Shreveport, LA. There should be a man at Grandbury with a 4hp FM N. His name is Bill Keene, he may can give you some pointers on your 25hp.
I will be tied up all weekend with dad duties.
I have the Lorain soaking with Kroil as it is the best for stuck pistons.
Bring your Dually on over and it may well leave with some kind of loosely organized scrap iron in it.
