41chevy Posted March 9, 2012 Share Posted March 9, 2012 This is in the Mack Museum PDF file it's on page 3. It looks to have a chain or belt driven injector unit on it. I assume it's a pre AC or AB engine. Some kin ship to my AC engine. Early diesel? Never saw anything like it.

Olivetroad Posted March 9, 2012 Share Posted March 9, 2012 I wonder if it is the lubrication system that looks like an injection pump? Pretty neat stuff!

JumperAndSon Posted March 9, 2012 Share Posted March 9, 2012 That's crazy. I bet Bob is right, it looks like an oil lubrication pump.Ben Quote Link to comment https://www.bigmacktrucks.com/topic/23718-what-is-on-this-engine/#findComment-106326 Share on other sites More sharing options...
41chevy Posted March 10, 2012 Author Share Posted March 10, 2012 I tended to think lube system like all suggested with the 16 lines. Didn't see any type of pick up though. Almost thought it was a Saurer Petrol Diesel. Lube system makes better sense.

lucerne tractor Posted March 10, 2012 Share Posted March 10, 2012 Thanks for the pdf, great reading, read it all. Question: what would be the letter model of the cab over that came out in 74 with aluminum cab and 500hp?Mack pushes horsepower and comfort to new heights with the1974 introduction of the Cruise-Liner. Created for the Westernmarket, the cabover features a popular riveted aluminum cab,larger radiator and engines rated up to 500 horsepower to masterlong runs through mountainous terrain.I looked for one in truckpaper but nothing came up.

41chevy Posted March 10, 2012 Author Share Posted March 10, 2012 74 to 83 Cruise liner is I believe called a W model.
