I have a Holt 4 cyl. engine made by the Midwest Engine Company.Side covers say Holt and the exhaust manifold has the wavy caterpillar script.Piston bore appears to be 6 5/8 inch.There is a plate on it that has Holt 55-75 HP engine Built by Midwest engine Co. successors to Lyons-Atlas Co.Indianapolis Indiana.I was able to find out Midwest engine was formed in 1918 and went bankrupt in 1922.Is this the same engine as used in the 10 ton?Was it common for Holt to contract with other companies to make engines?I'm missing one head and now the exhaust manifold has disappeared.I asked on here once before but found little information I'm hoping to find out more this time. Thanks

Could be similar to a ten ton. How many flywheels? What sort of clutch if it has one? Could be a combine engine. The self propelled combines used a 55 horse engine and had two flywheels. I’ve got a few 45 horse heads, not sure if they’d interchange. Now go find that manifold!!

Also pictures would be cool too.

I think I found what I was looking for,went to the archives and found a post by dtallon where he said there was a block of serial numbers assigned to T-16 (10 ton) tractors with Midwest engines.Engine has one flywheel with teeth for a starter(I presume) and a belt pulley operated through an over center clutch.As far as the manifold goes I have a family member who thinks anything not nailed down or locked up is fair game,or at least that is my suspicion.I tried to take pictures but my camera is junk and I need a new one.Have had the engine 40 years and figured I could work on it after I retired,but will probably have to work until I can't.It will probably be for sale.Be interesting if one of the 45 heads would fit.Engine was being used on a sawmill when I got it.

45 heads and 10 ton heads are close, but not identical. PM me if you need any 10 ton parts to complete it.

Testimonials

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
