First I Get Stuck and Then This

The Gehl 7810 ate it's water pump yesterday. (It is a 100 hp Cummins and the water pump is inside the block.) It gave a little squeal and then there was smoke everywhere. The belt was shreded and when I removed the pump it was totally destroyed (gone). The veins were gone, the bearings, and everything else. I found all of the veins and a lot of other stuff in the block but there are a lot of fillings and little pieces somewhere in there. I used a magnet and got everything I could but I am sure there is a lot left. I think it will all pretty much settle out. I plan to run it a little bit and then possibly have it flushed out. Any thoughts?

Better you than me? Sorry, that doesn't look like fun to get to, and the uncertainty doesn't help your confidence after the repair. You'd hate to ruin the new pump right away.

Just figured out I have to change the thermostat in the Boss' minivan- looks like engine/transmission removal is step one...
 
Anywhere you can stick a magnet to collect the pieces so they don't get in the pump or block a passage? Don't HAVE to get them out as long as you can stop them from moving. You are right, it looks like you are missing a few pieces yet. Good Hunting!
 

Dad has an 8510 agco white with an 8.3 cummins with an almost identical water pump. We have put in two within 1500 hours. Neither one self destructed like yours, but they both started leaking and bearings were getting bad. Clean out the groove in the block, usually they will start leaking before they grenade. They are easy to swap out, but I wish they lasted longer.
 
Seems like those B series Cummins are always eating up those water pumps and also the belt tensioner. Just never seem to last long. Probably both are made a lot cheaper than they used to be.

I would flush the crankcase before runnin it again, any of the filings will go through the crankshaft and take out the bearings, had it do it in my Oliver when the governor seized and put filings in the oil.
 
I was going to ask the same thing and that would indicate the coolant would also be mixing with the oil another bad thing.
 

You can get the waterpump from NAPA with a lifetime warranty....might save you some money in the long run. The directions on mine even warned that not flushing the system would result in shortened pump life. At least the Cummins is easy to change!
 
Not up on newer engines like such, but it happened on my brothers 9600 Jd. Internal water pump failed and dumped coolant and filings into the crankcase, toasted her just this last fall!
 
How many hours I've had 5 different Cummins engines in dodges all with over 250000 miles and 4 1998 and older only replaced 2 water pumps ever, both started leaking never desintegrated
 
Go directly to Cummins for B series water pumps. Even the lifetime warranty isn't worth a NAPA pump.

They are pretty easy to change with the o-ring seal instead of a gasket.

At half the price of a Cummins I will take a chance on the NAPA....especially when they look identical to the original Cummins. If you have debris in the engine you will take out either one...I would go for a free replacement every time.
