youngcountrypreacher Posted January 9, 2011 Share Posted January 9, 2011 Hey guys just wondering how rare are mack superliners and ultraliners with factory cummins engines in them. My friend in Ga has a 1985 mack ultraliner with a 400 cummins and 15 speed deep reduction in it from the factory . His is a MH633 instead of a MH613 he said the first 3 means it has a cummins in it. Also found a superliner tanker fire truck in the town I live in with a factory 400 cummins and 13 speed . Believe it is a 79 model. What was the rarity of these and was they special ordered or just built on the line and sent out to dealers? 1 Quote Proclaiming JESUS as SAVIOR to Truckers and all the World!!!!

There was a guy around here that had a 78 Superliner that had a Cummins 1150CID KT450,13 speed roadranger, on camelback rears. the engine compartment was full. dose anyone know how many KTs where installed in Superliners??.

David Posted January 10, 2011 Share Posted January 10, 2011 We parted out a MH with a 400 Cummins,7 speed Spicer (single stick), and 4 spring with 3.65 Mack rears. Probably the weirdest speced Mack I've ever seen. Quote Link to comment Share on other sites More sharing options...
Superdog Posted January 10, 2011 Share Posted January 10, 2011 Don't have any numbers for the MH,but my local dealer sold 2 new MH633's in '85,400 with 13 speeds.Last I knew they were both still around,but had been converted from tractors to fertilizer tenders.There were 170 RW633's built 1985 to 1993.Don't have any build numbers for the RW733's or the older Superliners.

jryoung Posted January 11, 2011 Share Posted January 11, 2011 I recently bought a 1979 Superliner (RWS768LST) with a Cummins KT-450, Eaton Fuller 15 speed with OD, With 55's on Camelbacks. She has pulled lowboys her whole life, with third axle, diamond plate headache rack with light bar, and full diamond plate fenders. I am the third owner and had the local dealer run the vin and it looks like drivetrain is original. She needs some TLC been neglected last few years by previous owner who replaced her with new truck. She hasent been licensed in about 5 years. I havent pulled anything with her yet but bobtail she seems pretty stout. I am planning to restore to new condition in near future and run her. They dont make em like that anymore. I will try to post some pics soon. Quote Link to comment Share on other sites More sharing options...

The latest superliner that I bought is the only one I have seen with a KT-450. According to the dealer this truck was built that way, they also said that this truck may have been custom built. It was built in California according to the tag on the door. The engine goes from firewall to radiator taking up almost the entire compartment. My other Superliner has a Mack E7-400 and it appears to be half the size of the Cummins. Quote Link to comment Share on other sites More sharing options...
vision386 Posted January 12, 2011 Share Posted January 12, 2011 I know of at least one Superliner equipped with a KTA-600 Cummins (though not factory installed) there was a guy in NJ before i moved that built an RW glider kit,1978-79? the donor truck was an extended hood W-900 Kenworth that had been wrecked. If memory serves it was backed by a 14 speed spicer SST trans. sat on kenworth air-ride susp. 3:35 rears,un-fortunately i do not have a picture of the truck,as it was sold,went to california i believe. But i DO remember it was quite a truck! sounded great! pulled a stainless 48' reefer out of the produce terminal at Vineland,NJ...............Mark Quote Mack Truck literate. Computer illiterate.

Mack Doctor Jr. Posted January 12, 2011 Share Posted January 12, 2011 I know the Walker Pulling Team bought an MH with a KT 450 in it. Used it for truck pulling then pulled the motor and put it in a Superliner then sold the truck before it was done. Its in New York somewhere.

Rob Posted January 12, 2011 Share Posted January 12, 2011 The 1693TA in my RL is a hoodfull!! There is very little clearance between the firewall of the cab and the rear of the head, and the cooling fan and radiator core. In fact, there is an access hole and cover in the firewall for servicing the camshaft on the engine.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

David Posted January 12, 2011 Share Posted January 12, 2011 "My other Superliner has a Mack E7-400 and it appears to be half the size of the Cummins." Almost half. 728 CID vs 1150 CID. Consider the Hp to weight ratio. Quote Link to comment Share on other sites More sharing options...
Lmackattack Posted January 12, 2011 Share Posted January 12, 2011 I think the superliner has another 3" of hood than that of a RS/RL700s. I say this as I measured my RS700 hood when parked next to a Superliner. I recall the superliner was a few " longer and the hood also sits taller due to the cab sitting a few " higher than a RS/RL. I know that the Cummins did not look cramped in a Superliner. in fact it looks just like any other truck that had one under the hood.

Lmackattack Posted January 12, 2011 Share Posted January 12, 2011 A great looking Superliner! looks about a 195"-200" WB? lots of aluminum. is the cab on air ride? Quote Link to comment Share on other sites More sharing options...
jryoung Posted January 12, 2011 Share Posted January 12, 2011 A great looking Superliner! looks about a 195"-200" WB? lots of aluminum. is the cab on air ride?Thanks, she needs some cosmetic work and a little TLC. She was a nice truck when she was new, hopefully I can get her looking new again in the near future. The cab is solid mounted (no air) but it does have air ride driver seat. The dealer said that it had 108" WB.Justin Quote Link to comment Share on other sites More sharing options...
