[12CHydraMac]

Hey all, I'm looking at an Hydra-Mac 12C I assume Series II.... It has a Chrysler H-105 4cyl Industrial engine Motor was taken out but they still have it, Said it started to Knock or something... I was told parts are Are available but Expensive, But nothing new to me! Was wondering if anyone can help me out, Need to KNOW if I can get a Rebuilt kit for it... Otherwise What is some other 3-4 Cyl Gas/Diesel Motor Replacements? Thanks!!! Btw, I run the Biggest & Only Hydra-Mac group on Facebook.
