GOOG Posted June 11, 2017 Share Posted June 11, 2017 I am half thinking of converting my Superliner from an E6-400 to an N14-500 Cummins. Anyone here have an idea how difficult and expensive to make such a switch? Would Mack even have this stuff anymore? Any help would be appreciated.

fjh Posted June 11, 2017 Share Posted June 11, 2017 You have E7400 maybe not e6 big waste of money in my opinion more feasible to instal mack V8 Quote Link to comment https://www.bigmacktrucks.com/topic/50145-anybody-ever-convert-a-rw-to-cummins-power/#findComment-372031 Share on other sites More sharing options...
GOOG Posted June 11, 2017 Author Share Posted June 11, 2017 If parts were not so scarce, I'd have that E9 in a heartbeat! I passed on a very nice CL700 last year. It was everything I wanted (heavy spec) with a fresh E9 V8. I know a couple guys with them, and they scared me away.

880joe Posted June 12, 2017 Share Posted June 12, 2017 There was a Cummins powered MH on St.Louis MO Craigslist a few days ago.

TeamsterGrrrl Posted June 12, 2017 Share Posted June 12, 2017 Be easier to just buy a truck with the Cummins engine you like already in it and running.

TeamsterGrrrl Posted June 12, 2017 Share Posted June 12, 2017 Are you building a work truck or play truck? Spending months re-engineering or even botching a major engine swap is wasting months you could have spent earning a living running the truck. If you're just playing around and have too much spare time on your hands, have at it!

dogg rescue Posted June 12, 2017 Share Posted June 12, 2017 I'm considering doing the same swap since I came across an n-14 for free still in the wrecked Volvo. Of course it would be a fair amount of work, and I figured I could just fab up some engine mounts. It just seems like a sacrilege to take out a Mack engine to put in a cummins. I would really like to put in an e-7.

TeamsterGrrrl Posted June 12, 2017 Share Posted June 12, 2017 N14 is longer than a Mack 6 and won't fit in a CH- That's why Mack built the CL. Makes more sense to rebuild what's already in the truck or swap like for like- Putting an N14 where it was never designed to fit would involve modifying the firewall and doghouse or moving the cab back and lengthening the hood, changing both the engine and trans mounts, fabricating intake and exhaust plumbing and adapting to the Mack radiator, etc.. If the transmission and final drives are a mismatch, figure on changing those too. Probably be easier just to build your own truck...

ekennedy21 Posted June 12, 2017 Share Posted June 12, 2017 a superliner nose is longer then a ch though. I believe a rw713 and cl713 has the same or similar frame, its just that a superliner axle is forward and a cl is axle back. I would say that can be done.

terry Posted June 12, 2017 Share Posted June 12, 2017 Got to agree with ekennedy21 on this one, there are factory superliners with cummins engines. terry Quote Link to comment https://www.bigmacktrucks.com/topic/50145-anybody-ever-convert-a-rw-to-cummins-power/#findComment-372139 Share on other sites More sharing options...
TeamsterGrrrl Posted June 12, 2017 Share Posted June 12, 2017 I believe Dog Rescue is talking about his CH, an N14 won't fit there. The N14 will fit a Superliner, Mack even installed some... Which is the easiest way to get an N14 powered Superliner.

Timmyb Posted June 13, 2017 Share Posted June 13, 2017 It's just an engine swap. People have been doing it for years. You could buy one with a cummins in it already, but you could be buying a lemon. These truck are 30 years old now, without proper maintenance it's a big risk. If you know your truck is good then I'd still consider doing it. Just giving a different point of view.

TeamsterGrrrl Posted June 13, 2017 Share Posted June 13, 2017 Sorry, thought you were thinking of a swap for your CH. Still wouldn't be easy with a Superliner, wonder if there's any way you could access a parts book and see what the differences were between Mack 6 and Cummins N14 engined Superliners?

thomastractorsvc Posted June 16, 2017 Share Posted June 16, 2017 I have a 78 RWL factory cummins 400 and 13 speed so a N14 will fit I would a cummins donor truck for the mounts as they are diffrent Quote Robert"I reject your reality and substitute my own."
