Bullheaded Posted March 1, 2020 Share Posted March 1, 2020 I was watching a show (Machinery of the Past) on the Rural Channel we have hear. A guy had an old Mack, I think it was 1930's? Anyway he said Mack used International motors at the time. I have never heard this? I'm thinking the guy was just mis-informed because Mack started out as International Motor Truck Company. So am I right or did Mack ever source an engine from International Harvester? Quote Link to comment Share on other sites More sharing options...
Rob Posted March 1, 2020 Share Posted March 1, 2020 I've seen several IH RD series engines in B models but cannot attest to any being factory installed.

Used to be a pretty common swap and almost looked at home under the hood. Farmer around here has a B-42T w/IH RD-450 from an original R-190 series tractor. I set the engine in there with a wrecker for them and it was a slip fit. Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Bullheaded Posted March 1, 2020 Author Share Posted March 1, 2020 Thanks guys. This truck pre-dated the B Model. I forgot what model it was. It was 1920's or 30's. But the guy was saying Mack used International motors in them because at the time they did not make their own engines. So I didn't know if that was true or not.

Well Mack made their own engines since atleast the AC which were built during WW1 so we know that much isn’t true, so what’s to say the rest is?

Popular Post Mike Harbison Posted March 2, 2020 Popular Post Share Posted March 2, 2020 Somebody correct me if I'm mistaken but I'm sure Mack has built it's own engine since the very 1st bus in 1900. I'm sure the guy was just misinformed or confused by the fact Mack was part of the International Motor Co.a partnership of Mack,Sauer,and Hewitt,at the time. On the subject of Macks with IH engines,I have 3 that have been repowered by RD450's,a B42,a EHU,and a H67. 4 Quote Link to comment Share on other sites More sharing options...

VaPatentman Posted March 2, 2020 Share Posted March 2, 2020 As Jim said they used Continental engines in some trucks. My "DE" has one made by Continental with "MACK" cast into the side of the block. Quote Link to comment Share on other sites More sharing options...
Bullheaded Posted March 2, 2020 Author Share Posted March 2, 2020 I had no idea Mack's were repowered with IH RD engines either. Thanks for all the info gentlemen. Quote Link to comment Share on other sites More sharing options...
steelman Posted March 3, 2020 Share Posted March 3, 2020 Mike Harbison is correct. Mack has built their own engines from the beginning. Mack Juniors and Seniors were Mack designed and built. Being interested in early Macks for the last 55+ years, I have run into many "experts" that called Mack part of IHC and other such rubbish because of the corporate name, International Motor Co. Take a look at the book "Mack" by John Montville someday. Came out in 1974, but they are around. Very well researched and written by a very nice fellow. 1 Quote Link to comment Share on other sites More sharing options...
