CaptainCrutch Posted February 21, 2020 Share Posted February 21, 2020 (edited) Anybody know what engines and transmissions were in the Mack MH Ultraliners that were owned and operated by Mack for use at their factories? I’ve included some pictures to hopefully help clarify what I’m talking about... Edited February 21, 2020 by CaptainCrutch 1 Quote Who needs a back yard when you could have a Yard?!

Vladislav Posted February 21, 2020 Share Posted February 21, 2020 (edited) The truck in the Museum (the last pic in your post) has E6-350 4V Mack engine and the most probably T2090 9-speed Mack tranny. It could also be T2100 10-speed as they utilized the same housing but 9-speed seemed as a more common unit. But if you look at the pic you took in the junk yard you can see the airfilter housing is different. I'm not ready to state that's just another style of the canister on the same type engine (I doubt) or the truck was equipped with Mack E9.

kscarbel2 Posted February 21, 2020 Share Posted February 21, 2020 The day cab (CA60) has the standard 11-inch (single element) air cleaner assembly applicable to Mack engines. The other truck has the larger optional 16-inch (single element) that was only available with the (CAS62) sleeper cab. Most customers spec'd standard frontal (air) intake, while Ryder preferred the optional snorkel air intake with their Cummins (MH632/633) and Caterpillar-powered (MH652/653) Ultra-Liners which were paired with either a 13-inch air cleaner (CA60) or 16-inch air cleaner (CAS62). An in-line "pre-cleaner", and inside-outside air intake with in-cab control, were also options. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/61084-factory-ultraliner-specs/#findComment-443429 Share on other sites More sharing options...
