Couple of pics from my shop at the mine doing a scheduled major rebuild on our Hitachi 2500 mass excavator.  Doing an engine swap here are pics of the Cummins factory reman engine sitting in the module.

Engine is a V16 QSKTA 50

1500 horsepower

Any noticeable engine wear/problems or was it just up on hours? 

 

Also... movie night in the shop?

Ha Ha the popcorn buckets are for general parts use we buy them by the pallet full. Unit was up on scheduled hours, doing this one a bit early @ 22K hours were hoping for closer to 24K but dirt work schedule coming up didn't allow for doing it down the road any further.

i'd love to see the inside of that engine, crank bearings, flat tappets, all of it. You send them back to Cummins correct?

 

Yep Cummins get it back.

I fixed it didn't I?

 

I posted it on my phone and didn't catch the auto mis-correction spelling of it before I hit submit lol.

 

Ha Ha I missed the one in the post itself, it screwed up the title on me too.

I briefly considered asking you to ban yourself. 

 

We ran those engines on frac pumps.  Ours did not last as long as yours...  They were run until they stopped running or blew up.  Something about running well past normal continuous power for months on end. 

We have two of these machines and the engines have been really impressive other than normal leaks here and there. We did have random injector failures on both machines at roughly the same hours so we replace the injectors every 6k hours as routine maintenance.

Those are massive engines... 1500 HP is nothing to sneeze at.

We never did much other than oil changes when they first showed up.  A couple techs hot rodded them from the factory and even on the stock ones we ran them around 2200-2600 hp on 100% duty.  The tweaked CAT 3412s were up around 3200hp for one season, then kaboom.  

I think the philosophy changed not too long after I left that side of the company and they actually built a PM program.

Here is a few pics of a upper rod bearing from a QSK. Was at Cummins Npower for X15 qualification and the trainer had this on his desk. That's a damn big bearing compared to the ones I usually play with. I put my tin of chew for size comparison ?
