I'm looking for componets to rebuild a spare engine I have for my oc-4 Oliver. It's a 3 cyl gas engine complete but I'd like to go threw it from top to bottom before I put it in the crawler.
any info on wher to start looking for componets would be appreciated.
Thanks for your time!
 
It is a 130 cubic inch Hercules, But the first ones are not like the last ones. Cranks are not the same size plus some of those gas engines had cylinder sleeves. What version do you have? Do you have the I & T /Oliver shop manual for that engine? Do you know Jerry Biro? He is North America's largest Hercules parts dealer.
 
I know it is a hercules but at this point I do not know if its a earlier or a later model. I won't have a chance to check untill after tuesday of this week. I have never had any contact with Jerry Biro, where is he located? I will try after tuesday to get some numbers off of the two engines I have and will repost info on here. Thank you for any info you have. Hope to hear from you later after I post the block numbers.
 
As a update to my previous post I now have the numbers off the left side of the two engines.
The one that is in the machine at present is
GO-130H 3752685
The spare engine has on the left side of the block -
GO-130 3752420
do's anyone know if these engines are the same size crank , ect.
Thanks for all info ahead of time
 
The Go-130 has smaller crank journals as follows:
mains : 2.4965-2.4975
Rods: 1.987-1.988

The Go-130H is as follows:
Mains : 2.8734-2.8744
Rods: 2.4976-2.4986
All this is from my Factory Shop manual
