john schoneweis Posted January 9, 2021 Share Posted January 9, 2021 I've driven and owned Mack trucks for 35 years starting with a R model with a 237 5 speed with many in between. I just bought a 1984 Superliner with a 440 E9 engine. It needs overhauled. Any advice on parts and service would be appreciated. 1 Quote Link to comment Share on other sites More sharing options...
