Any bad issues with this model truck? thanks,MarkMark, Did they make an e6 400 ? I had a E7 VMack that i bought new, one of the first Electronic motors in my CH 600. Now when I got the truck it burned oil, then it burned more oil, so Mack brought it in and pulled all 6 pistons and found broken rings! They fixed it all under wrt. And after that I had no trouble at all with the truck, I just sold it in Jan. but the motor ran good and had a lot of power 2090 trans an 464 Mack rearsBULLHUSK Quote Link to comment Share on other sites More sharing options...
lucerne tractor Posted September 6, 2013 Author Share Posted September 6, 2013 Bull, it says e6 400 in the add, I tried to look up the torque and only came up with an e6 350. I wish it was an e7 400, they have torque, maybe it is, 1988 what did they offer in superliners,? anyone? Quote Link to comment Share on other sites More sharing options...
Solution Superdog Posted September 6, 2013 Solution Share Posted September 6, 2013 They never made a E6-400, just a 350 with the pump bumped up. Quote Link to comment Share on other sites More sharing options...
lucerne tractor Posted September 6, 2013 Author Share Posted September 6, 2013 Doesn't look like they made an e7 400 in 88 either, so it must be an e6 350? I see a lot of e6 350's in 88 on truckpaper. Am I wrong? Quote Link to comment Share on other sites More sharing options...
countryboy5487 Posted September 6, 2013 Share Posted September 6, 2013 Im with superdog its most likely a e6 350 cranked up to around 400 Quote Link to comment Share on other sites More sharing options...
rsb502 Posted September 6, 2013 Share Posted September 6, 2013 Well if its an 88 its not got a stock 400, however you can swap engines I know where there's an E6 Superliner that has an E7 in it now. I always thought a mechanical Mack 350 ran awfully well, great throttle response and low end. As for reliability they are hard to beat, I know where a 93 CH with an E7 400 is that's never had the heads off, same for a 95 350 actually.

Yoos Brothers Construction Posted September 9, 2013 Share Posted September 9, 2013 My Dad knew of a block company that bought a Superliner in late 1989 for a block truck setup like the ones we have at work with one of the very last E6 engines and it was a factory 400 with a 12 speed and all aluminum wheels. He said that it was one hell of a runner and it looked really sharp doing it.So an E6400 does exist. Just my 2 cents. Josh 2 Quote Link to comment Share on other sites More sharing options...

bbigrig Posted September 9, 2013 Share Posted September 9, 2013 In 1989 they were rolling out E7-400 mechanical engines. A company I wrenched at in Mississauga by the name of John Grant Haulage had 1 of 20 CH's built at Mack's Oakville assembly plant. (the only 20 Canadian as I understand it....Mack Canada serial plate CH613 #001020... I want this truck!!) Grant Haulage was one of the Canadian Fleets they use to test stuff out on for heavy loads like the 1000 series V8's etc. Most of the trailers were 3 and 4 axle.the CH was built in '89 and had one of the first E7-400 motors.(mechanical) they still have the truck doing yard work and runs like a clock. Doesn't make sense that they would bump up an E6 to 400hp when the E7's were already finished field testing and in production for the CH roll out. The '89 Superliner may have had an early E7???

b61mack Posted September 9, 2013 Share Posted September 9, 2013 At work we have a 90 CH that has an E6 350. when was the last year for the E6, and when did the E7 come out. Quote Link to comment Share on other sites More sharing options...
bbigrig Posted September 9, 2013 Share Posted September 9, 2013 The E7 350 and 400 versions were unveiled in the Bulldog magazine 3rd edition 1989. The first 377 E7 engines were built in late 1988. In the announcement the "425" model was to be released in Jan 1990. That never happened until V-Mac II as the 427. The E7 and E6 were built concurrently into 1990 where the E7 would replace the E6. Not sure when the last E6 for new production was built, I'm guessing it was 1990?? I do believe the Phoenix 1000 series of CH's (First 1000 built) were E6's built in Jan. 1989 Quote Link to comment Share on other sites More sharing options...
Superdog Posted September 10, 2013 Share Posted September 10, 2013 Friend of mine has a '89 CH with a E6-350 and a 12 speed,bought new and clean as a pin. I'd like to see a E6-400 in person,or at least a pic of the engine tag. 1 Quote Link to comment Share on other sites More sharing options...
james j neiweem Posted September 10, 2013 Share Posted September 10, 2013 If I remember right when the first E-7's came out there were problems with ring and piston breakage. Quote Link to comment Share on other sites More sharing options...
bbigrig Posted September 11, 2013 Share Posted September 11, 2013 Yes. The first E7's had a different piston material and design. The first piston was only used for about a year of production if I remember correctly. Quote Link to comment Share on other sites More sharing options...
Sean MACKeever Posted June 24, 2015 Share Posted June 24, 2015 I've actually just been and checked and I am mistaken, Mine is a E7-400, I thought it was an E6-400 but no. So yeah, I agree with you there Superdog. Quote Link to comment Share on other sites More sharing options...
fullfuel01 Posted June 24, 2015 Share Posted June 24, 2015 Mack made the E6-400. I dont know how many. They went in the first CH series. Quote Link to comment Share on other sites More sharing options...
gearhead204 Posted June 25, 2015 Share Posted June 25, 2015 if its a mechanical 400 just buy it ! the only problem we ever had was the pump shop got the advance wrong and we smoked a overhaul after fixing that issue the truck was as bullet proof as a e-6 350 and just a little stronger, that superliner it was in was paving and hauling 101,000 lbs. ran great!

Pipelayer Posted November 13, 2021 Share Posted November 13, 2021 I’ve got a 90 ch. What was the first year for a ch? And how do I tell if it is an e6 or 7? Quote Link to comment Share on other sites More sharing options...

I agree here. Have never heard of or saw an E6 400, but ran an E7 400 mechanical. And had friends that swapped their E6350's for E7 400's. Both the E6 and E7 mechanicals were awesome reliable motors. I ran every year of Mack back then and I never had issues until 2000 and up. 1 Quote Link to comment Share on other sites More sharing options...
