Hello,
finally got my first UOA done. It is from my parents' farm tractor, a '97 Case IH Maxxum 5120 Pro. They run it 1300 - 1400 hrs. a year for daily feeding and material handling and there is a lot of engine idling.
Some more details:
- I consider this Case 4T 390 engine to be much like a Cummins 4BT 3.9.
- A belt driven Wabco air compressor is connected to the lube system (I actually forgot to tell Terry).
- An OC takes about 11.7 Qt. This time it was 2/3 Delvac 1 CI-4 Plus and 1/3 CH-4.
- Oil consumed over this interval was about 1.6 Qt.
- Make up oil was 1.2 Qt Delvac 1 CH-4.
- Fuel consumption over this interval was less than 1000 gal. of B5 50 ppm sulfur diesel.
- Coolant: Caterpillar ELC. Withing 2400 hrs, the coolant level went 1 Qt (or so) low.
- Oil filter: Donaldson Endurance ELF 7349.
- Air filter: Donaldson long-life paper.
Here we go:
Except the viscosity brake down, glycol, TAN and lead reading, it is much better than I expected.
Can a different add pack in the European formula skew the glycol test? 0.84 is a lot.
Is a certain level of coolant consumption considered to be normal for HD applications due to evaporation etc.?
Comments please.
Regards,
ED
