Combines cummins engines

[Silver_Aussie]

G'day dakota, We had a 8.3 blow in our R-62 with just 20 hours on it and had a lot of trouble getting it fixed. Also had a fuel leak on it that took about 2 mins. to fix, had dealer out for a couple of other jobs and said he couldn't touch it. Had to get cummins out (130kms) to do it!!!!!!! Dealer has heard that there will be cats in gleaners soon though.... Bring em on. Regards, Silver Aussie.

They are both N14 engines and both spun a bearing. The first one needed a different engine, because the push rod knocked a big hole in the side. The other one needed a new crankshaft and camshaft besides all the other usual overhaul parts. They blew up within two weeks from each other. The second one was still under warranty and had bad oil samples for the last two years, but Cummins ignored it. Other trouble we constantly have are oil leaks, leaking head gaskets, accessory drives going out, etc. No trouble on our CATs and Detroits.

The descriptions and terminology in your posts cause one to wonder. lets start with a specific question. What do you mean by. The second one was still under warranty and had bad oil samples for the last two years, but Cummins ignored it. Was this engine in a maintenance programIJ Or did the owner do the service and samplingIJ

 

[dakota]

We have a maintenace program, just as many other fleet operators and take oil samples on a regular basis from all trucks. The lab tells us about abnormal findings. We inform the dealership, where we bought the truck from. The dealership informs the manufacturer, if the engine is still under warranty.

Could there be friction between the testing lab and the dealershipIJ I also have regular oil sampling done and have wondered if another dealership might get bent noses because I am not using their service. Could that be a possibility for youIJ

Not to sound judgemental but if you had an engine that was returning bad oil samples for TWO YEARS.... why did you wait till it blew itself up to get it repairedIJIJ In all honesty if i were the engine manufacturer and I found out a customer was running an engine for TWO YEARS that had returned bad samples ( for TWO YEARS) I would be extremely hesitent to warranty a blown engine also. But hey thats just me.

The testing is done by an independent lab recommended through our oil supplier. We have even switched oil brand, supplier and lab during that two year period and got the exact same results.

Cummins was notified from the first bad sample on and every time there was another one tested. But every time they told us to keep going. They made the decision, not we.

I know some people that have gone form Cummins to Cat in their new trucks, but I have never asked why. So is Cat making a better engine, and how dose Cat compare in priceIJ Thanks Dee

We have four CATs in our fleet. All of them combined give less trouble than either one of the Cummins. We overhauled a CAT, a Cummins and a Detroit last winter. The CAT turned out to be considerably cheaper than the Cummins. The main reason was, that more pieces on the CAT went back for core, while everything on a Cummins but the heads is throw away. The way the CAT is built it took a lot less hours to do it, too.
