As I talk with Concrete Pumping companies I keep hearing more and more Mack Trucks issues

The frustration level of Mach Truck users is growing all the time. I really believe the customers have to just switch and quite buying Concrete Pumps with Mach Trucks. This survey was taken back in 2007 when people were asking will Volvo's ownership of Mack make them a better company or a worse company. Looks like the guys who thought it would make it a worse company were right.

2016 was one of mack worst years since 2010 and 2017 was little better. How in this economy can things be so bad for Mack and how can they act the way they do towards the Concrete Pumping Industry?

What kind of issues are these Mack owners experiencing?

Well this could take a while , lets start with it seems as though the regen systems are a little better but not full proof , there's multiple coolant sensor issues , rear end issues , frame issues , I am not sure if its all Macks fault , as these days our pump systems communicate through the ECM with the Mack components , in my opinion we have a overload of electronics on the trucks and pumps which is still at best in experimental stages , no one manufacture has the regen issues fully resolved , hopefully it's coming soon and we can have our pumps pumping instead of them being at Mack dealerships all over the country.

Mr.Pudg, has one of your trucks actually shut down because of the problems or does a warning light just stay lit on the dash? Reason im saying this is we have a truck with an electical malfunction and check engine light on,but the truck runs fine.

there's two lights , one is a check engine and another shows service engine light , one shows that you have a malfunction code the other ( check engine ) is more serious , look in your operator manual for that truck and it will explain the difference , one needs the truck needs to be brought into Mack , the other it does not.

But yes we have had trucks shutdown and need to be repaired onsite or on the road.

Oh man , there's been everything from DEF pumps , coolant sensors , replacing rear ends , its kind of funny though , we bought a 2015 out of NY , this pump does not have all the computer crap that comes on the newer pumps , at least pump side , and we have had 0 issues with this truck , that's why I am not convinced that it's always on Mack , I do believe sometimes the pump and truck computers do not communicate properly.

I think the problems with Mack are hit and miss, the 2012 I currently run has had zero problems with the Regen side of the exhaust save for a cracked DPF component at around the 7000hr mark. Had Mack do a dosage test when the truck was in for a injector set last year and the system tested perfect. I've heard of 2013/2014 trucks have multiple exhaust related issues (the 2014 I ran for previous company spent a fair bit of time in the shop for exhaust related issues from new). Outside of age related wear and tear I haven't had issues on the 2012 chassis. The Mack dealer here has been very good about getting problems I have encountered solved reasonably quick and explain ways to prevent further issues.

On a side note, for those in Canada running Federated Co-op Fuel in their tanks, STOP. I've been talking with a few diesel techs around my area and have been told that the Cetane rating and the actual water ratio in the fuel is not what is advertised. Newer injectors can not handle this fuel blend and as a result the injector nozzles are cracking. Cummins and Kenworth, from what I've been told will not warranty injectors on newer engines that have Co-op diesel running thru them. After my set last year I switched to Shell diesel and have noticed a huge fuel economy jump and more power driving down the highway.

Any of you have any Idea's on what to look for or what can be done when looking at pumps mounted on the 2008 Mack ?  Can the problems be Deleted ? OR ???

Believe it or not , the air compressor and system cause a lot of issues in the 08s , you have to keep the air tanks drained daily , moisture wreaks havoc on the regen system , as far as deleting the system there is a kit you can have installed , I do believe it is around 10k , but if you get caught I would think those fines would be extremely high depending on what state you are in.

I'm not sure of the reliability after a Delete on an MP series. I've heard of a few MP8's in highway units pulling fuel, melt down the engine after a few months.
