IT28F engine problem sounds bad.

Hi

I got the Case 7110 electrical system squared away this afternoon.

So I took the time to remove the fan drive belts and check the alternator and fan bearings to see if the was the squawking noise we heard. I found the water pump drive belt loose so tightened it and put the fan belts back on.

I ran it for a couple of minutes this time and I can hear the knocking noise but it is not near as bad as it was in the past.

Have a look at the video and see what you think.

The bearings in the water pump belt tensioner are famous for failing in these engines. When that happens the water pump belt slips and the engine overheats.
These engines are pretty sooty and dirty running I would recommend more frequent oil changes.

I run 500hr oil change intervals on my old mechanical motors. I have Deere 6059s running original everything's with over 22k hours.
I did lose the third 6059 at 19k hours when the balancer separated. Windowed the block and oil pan with a main cap. Drove it on a trailer with no oil, drove it off at the other end, with no oil...innards looked like a 5k hour motor, save for the added ventilation.

I just don't see a problem with 500 hr intervals.

I'm running 400 hr intervals on all my newer stuff, though.
Never seen a sample that says that I'm doing it wrong on either interval.

I just fixed that I am not a lover of YouTube so I am not very use to the way it works.

I’m only talking about a 3116 when I say 500 hours is high. If they aren’t tuned exactly right they produce a lot of soot in the oil.

Somebody’s knocking shut her down! You had me cringing by the end of the video.

I agree. I've seen a fair bit of oil analysis that suggests the 3116 are "dirty" unless they are set up 100% on the fuel side.
Additionally from the OP's descriptions of the operation it sounds as though it's not exactly kind to a machine. If you had a mind to you could easily classify it as severe service. That in itself would qualify to cut the oil change period in half from the one recommended in the manual, although the recommended interval is every 250 hours anyway. If it was my engine no way would I be changing the oil every 500 hours, it probably comes out the drain plug hole like tar.

Hi

I have a couple of minutes this morning.

I haven’t got the oil analysis back yet.

The oil changes haven’t indicated anything abnormal

Nige and the rest of you any guess as to what is knocking?

This happened all of a sudden no prior warning the machine was being transported from the north end of the property to the middle about 4 miles when the operator heard the noise come on suddenly and shut down immediately.

Also the engine has 5,963 hours on the meter.

Pull the valve cover and check every valve rocker and push rod. Then drain the engine oil and see if there is metal in it. Also, check the water level in your radiator and make sure none of it is in the oil pan.

Hello all.

I am back from my trip to Texas to take care of a couple of turban engines that I had contracted some months ago. At least these were just an inspection and oil change that was simple and fast.

Now I have all of the engine information. All metal was high from Lead to Tin.

From the information I got from the operator that was running it when he shut down for noise and then the assistant manage ran the engine more after towing to the shop I suspected a major rod bearing failure and the additional running of the engine has cause one of the bearing shells to shift enough to tighten the rod up on the journal so it is now hard to identify what we are hearing.

As a precaution I have sent a transmission oil sample in for testing. If it returns nothing abnormal we will remove the engine and send it to the machine shop for rebuild.

Now I have a question for you all.

I found an IT28G located in Florida with a bad transmission engine model 3056 Selling price about what the engine rebuild will cost us. Has about 11,000 hrs on it. Can that engine be put in the IT28F?

Both IT28F and IT28G use the 3116 engine model, however there could be differences based on build date, etc. No idea where the 3056 comes into it.........
Serial Number of the IT28G.?
With that I can compare the two engines and let you know.

My 2c. With 11k hours on the other machine the engine is probably close to being ready for rebuild anyway. Make of that what you will.

Thanks Nige

The first page I pulled up on the Internet has the 3056E engine listed I did another search and find it is the 3116T as you noted.

My machine shop is not very complementary of the 3116 so when I thought the G had a different engine in it I would consider that rout.

I am not interested in purchasing the same engine with high time on it so we will continue to go with the rebuild provided I don’t get a bad transmission oil report.
