Hey, i just bought a harvester 574, and i got diesel fuel running into my engine oil! The engine does not have a fuel lifter pump, so do you think the fuel is leaking from the rubber sealant from the shaft on the pump?
Most likely the front seal on the injection pump drive shaft. Before the pandemic, The seal as described from CaseIH is >$20. the number 3078355R2 crosses over to a NAPA seal for $6. The seal from CaseIH has the embossed designation: Kaco 30 DF17 28. 7.3 TVF03, is 17 MM Bosch seal # 1 460 283 312 NAPA takes a couple days to get it in, but so does CaseIH. DO NOT LOOSEN the 3 Cap Screws on the pump drive hub, just the big nut on the drive shaft.
