jarhead1229 Posted September 17, 2016 Share Posted September 17, 2016 I'm having problems with my 2005 cv713 Granite passing emissions. Mack wants $20,000 to get it to pass. So I'm wanting to change out the mack engine with a c-15 cat. My question list is quite long so I guess we'll start with the basics. Will it fit under the hood? Is the radiator big enough to keep it cool? Is there an easy way to hook up the ECM or will it need rewired? I suppose those are my biggest worries that I can think of now any help I can get will be greatly appreciated Thank You Quote Link to comment https://www.bigmacktrucks.com/topic/46876-cv713-engine-replace/ Share on other sites More sharing options...

Underdog Posted September 17, 2016 Share Posted September 17, 2016 The engine is running? You're using the truck every day? The only thing that could cost $20,000 is a complete engine replacement. You need to find another Mack dealer. And no a Caterpillar C15 will not fit under the hood of a Mack Granite don't even try. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/46876-cv713-engine-replace/#findComment-345946 Share on other sites More sharing options...
fjh Posted September 17, 2016 Share Posted September 17, 2016 Where are you located? theres no good reason why that engine wouldn't past emissions a new after cooler and a turbo and a clean air. Filter and maybe a set of injectors at most somthing fishy unless the wrong cam has been installed.

jarhead1229 Posted September 18, 2016 Author Share Posted September 18, 2016 Yes I use the truck every day it runs just fine I'm located in Salt Lake City Utah and according to the shops in the area a lot of the Mack trucks are having issues passing the new emission standards. My biggest issue with the truck is it claims to 460hp but compared to my 02 378 Pete with a 475hp cat, the Mack is kind of a gutless wonder. I've considered possibly a bigger turbo to get some more air and hopefully that would give me a little wider power band as well just not sure that's why I decided to post here and pick you guys brains Quote Link to comment https://www.bigmacktrucks.com/topic/46876-cv713-engine-replace/#findComment-346114 Share on other sites More sharing options...
Dirtymilkman Posted September 19, 2016 Share Posted September 19, 2016 Wouldn't your truck need to pass '05 emissions, not new emission standards? Quote Link to comment https://www.bigmacktrucks.com/topic/46876-cv713-engine-replace/#findComment-346146 Share on other sites More sharing options...
bts-4120 Posted September 19, 2016 Share Posted September 19, 2016 if your showing up with a stock AI 460 and expecting it to pull with a pre emmision C15 475 which is actually 490hp your in for a shocker. the programing in the AI series sucks and it was made gutless to pass emmisions. Yeah He would be needing to pass 04 emmisions which should not be a problem.

jarhead1229 Posted September 21, 2016 Author Share Posted September 21, 2016 I know I'm allowed 18% but I'm blowing 19% and I've never seen my cat cat blow more than 8%. Which is why I was thinking of changing out the engine. But it sounds like it wouldn't work anyway so I'm not really sure where to go there aren't any other Mack dealers near me and this is dump truck so I don't leave the state ever and none of the shops I've been to are willing to even touch it Quote Link to comment https://www.bigmacktrucks.com/topic/46876-cv713-engine-replace/#findComment-346385 Share on other sites More sharing options...
41180 Posted September 21, 2016 Share Posted September 21, 2016 Rochester diesel . You can get injectors and turbo for your truck . Claims 500 to 600 hp . Rebuild your engine and install the injector and turbo upgrades .

fjh Posted September 21, 2016 Share Posted September 21, 2016 What test equipment are they using? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/46876-cv713-engine-replace/#findComment-346404 Share on other sites More sharing options...
jarhead1229 Posted September 23, 2016 Author Share Posted September 23, 2016 Not sure what equipment but I took it two different shops with the same results Quote Link to comment https://www.bigmacktrucks.com/topic/46876-cv713-engine-replace/#findComment-346590 Share on other sites More sharing options...
Challenger Posted September 27, 2016 Share Posted September 27, 2016 I feel like an apprentice because I have no idea what emissions test you guys are talking about.

nelm1994 Posted September 27, 2016 Share Posted September 27, 2016 Have you tried to run bio diesel just to pass the test. I have a 2006 cv 713 ai460 and it was a dog until I put Rochester stage 2 injectors , there granite turbo upgrade and an area diesel tuner. Its a lot better but still not great. I have to watch the egt. Those up grades will not help you pass emmisions . My truck smokes under load .
