Dieselman350 Posted Wednesday at 11:07 PM Share Posted Wednesday at 11:07 PM I have a 01 CL713 E7460 with a Maxitorque 18sp and air ride quad axle dump truck which has been extremely reliable and will probably keep it with they still made them. But I'm leaning towards a new or newer Granite MP8 505 13spMdrive and the Mride suspension. I just read alot of negative stuff about these newer trucks I can't afford to have it at the shop all the time. What are you guys seeing for reliability on these new trucks I know it's a loaded question. Also it's only local hauling so not big miles a year about 50k Quote Link to comment https://www.bigmacktrucks.com/topic/75329-new-granite-yes-or-no/ Share on other sites More sharing options...
Popular Post Joey Mack Posted Thursday at 12:20 AM Popular Post Share Posted Thursday at 12:20 AM The second time the MP-8 lays down on you because of exhaust or injector cup issues, you will wish you never had this idea... I will never change my opinion about this engine. It is a good engine but all the govt. Crap bolted to it will always be a problem... You have a CL -713... And your happy.. quit while your ahead... Ok.... Now its time for other opinions.... 3 2 Quote Link to comment https://www.bigmacktrucks.com/topic/75329-new-granite-yes-or-no/#findComment-572119 Share on other sites More sharing options...

Dieselman350 Posted Thursday at 01:32 PM Author Share Posted Thursday at 01:32 PM I love the truck I have. Just parts are getting harder to find and it is getting older, so it needs a little more maintenance . I would love to be able to buy a brand new CL. I am with you guys, though. I feel like I could put a new box on it and do quite a bit of maintenance for less than a newer truck. And still have a really nice truck. Was just curious on the new engine and tranny combos Quote Link to comment https://www.bigmacktrucks.com/topic/75329-new-granite-yes-or-no/#findComment-572141 Share on other sites More sharing options...

67RModel Posted Thursday at 01:46 PM Share Posted Thursday at 01:46 PM At some point these 90s and early 2000s will become obsolete either through parts availability or attrition. In the 90s there were probably some trucks from the 60s still on the road. Now there are probably none of those left. I suspect the same will happen with these E7 and ETech trucks. The question is how old are you and how much longer are you going to run? If its more than probably 15 years then its probably worth it to buy new. In 10 or 15 years if your Granite needs an engine one will be available. I have no ownership experience (just some driving) with an MP8 / Mdrive. But based on what I have read, seen, and heard I would not purchase an Mdrive transmission. I would opt for an Allison RDS instead. More money for sure but bulletproof. The Mdrives seem to be more problematic than the engines. And they are delicate little single countershaft units. Sure there is a lot of torque limiting safeties and nannies but in my eyes it doesn't have good bones like the MP8 engine does. As Joey said. The MP8 is good but is handicapped by the emissions junk. But then again all new engines are. Buy the new one, keep the CH as backup, and don't look back.

Joey Mack Posted Thursday at 02:33 PM Share Posted Thursday at 02:33 PM As far as replacement engines a few years from now..... I may have the answer. I may be receiving some core engines to rebuild.. Just waiting for my Buddy to get back to me.. 👍 Quote Link to comment https://www.bigmacktrucks.com/topic/75329-new-granite-yes-or-no/#findComment-572152 Share on other sites More sharing options...
The Heinz Posted Thursday at 07:12 PM Share Posted Thursday at 07:12 PM The mDrive is a problematic setup in general. Brand new trucks have come in with burnt clutches, and like 67RModel said, they don't seem to hold up to the abuse a dump truck sees. The few dumps I've seen with mDrives ended up having a lot of transmission issues throughout their life. They're extremely fickle with their air supply, so you HAVE to be on top of your air dryer maintenance and draining tanks. If hardly ANY water gets into that control housing, you stand a high chance of paying for a brand new transmission with control housing. I can't recommend those transmissions to anyone who isn't a massive fleet with near-endless money. I'm not too impressed with the engines either. The pre-common rail engines weren't too bad, but we've seen a lot of injector failures with the new common rail engines, along with camshafts deleting their own lobes. Hope no one needs one of those camshafts, because they're now made out of unobtanium; more than 200 VOR orders ahead of ours! Nobody makes a good product anymore. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75329-new-granite-yes-or-no/#findComment-572168 Share on other sites More sharing options...

Mark T Posted Thursday at 09:06 PM Share Posted Thursday at 09:06 PM 😂 I even cut that plug off the bowl on the one and threw them away. They were so much fun to try and get back on alongside the road when it was 2 degrees.

mowerman Posted Friday at 02:02 PM Share Posted Friday at 02:02 PM Just my opinion… I would suggest moving up but as he mentioned equipment is so expensive these days… I would just keep that one going… most everything you might wear out is available… bob 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75329-new-granite-yes-or-no/#findComment-572226 Share on other sites More sharing options...

Yup Heizy they can't leave shit alone there's always a better way ! 🙄 That push together Cam idea was an accident going some where to happen! And as I have said before that dollarstore fuel system should have never happened ! They needed to have put a proper bosch HI system on the engine it would be almost bullet proof ! they needed to have redesigned the head totally and fix it properly ! They just add insult to injury it seems! 😡 2 Quote Link to comment https://www.bigmacktrucks.com/topic/75329-new-granite-yes-or-no/#findComment-572227 Share on other sites More sharing options...

By the time the plug part on the engine harness is green, the rest of the harness is shot anyway. I worked on a a Volvo once ( I can't believe I fessed up to that in print ) It had Baldwin filters on it. Someone had that plug stuffed in the front bumper as the Baldwin replacement was just your typical spin on with only a little drain cock on it and no provisions for the bowl. I did try those filters on an MP7. went right on and had a fuel pressure fault until they came off the next day. Nothing about the water in fuel though.

Joseph Cummings Posted yesterday at 03:12 PM Share Posted yesterday at 03:12 PM I can remember going through lots of fuel filters. Back in the day before red fuel was a thing we had a guy that did oil tank removal and cleaning on an industrial scale. (I'll bet you know where this is going lol) He had an old Transtar with the right headlight panel and part of the bumper torn off and a bunch of old tank trailers (One without baffles, but that's another story) and he had bible passages painted on all his stuff. Well when he got a load that was kind of clean looking, he'd sell it to some guys I knew who had bulk tanks at their yard for next to nothing. But damn the algae it spread. I found out about Kathon FP .005 from my dad who worked developing it and dosed the tanks. It killed it, but the dead algae was still in the fuel. I built a bypass filtering setup and it helped some, but everybody was still going through lots of filters. Everybody kept buying it though while it lasted. Changing filters like every week or two was cheaper than buying fuel at the pump. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75329-new-granite-yes-or-no/#findComment-572296 Share on other sites More sharing options...
