IH 412 & IH E200 overheating issues

Greetings all,

I've have two IH scrapers I'm having over heating issues with. The 412 required replacement of the water pump when I acquired it as the pump seals gave out and it was leaking all over. After replacing it however I have had issue with over heating when under load and I am having the same issues with the E200. Both are topped off with a 50/50 mixture of coolant, both exhibit no leaking or loss of coolant until the temps get high enough to force it out the cap. I have pulled the thermostat off of the E200 believing it may be sticking however that hasn't made a difference in either direction. The scraper still overheats upon exertion. It doesn't take long for either machine to cool down when left to idle. The gauges on both units were not functioning when I purchased each one respectively and I replaced both the gauge and sending units however all that did was allow me to better monitor the over heating conditions short of the steam coming out the cap. Are there any known anomalies with either machine (one having the DT361 and the other the DT466 engines) that might speak to what is going on? I do not suspect water pumps on either as one has been replaced and the other shows no visual or audible sign of failure. Appreciate any information provided.

Are the radiators clean inside and out?
Also check if the fluid is bubbling in the radiator,.

My bad. I didn't see this till today. Unfortunately weather has not allowed us to use the scrapers much to my disappointment. No traction what so ever in the saturated clay. We had looked for bubbles and found none. We also flushed the whole cooling system which did not reveal anything. I did replace the water pump on the 412 as it was leaking through the seal. I was told the pump had been replaced on the E200 however I am dubious about that as it is certainly a water pump of the same age of the machine. Paint, wear, and all. There is no leaking going on with it and I would think if the impeller shaft were compromised it should leak all over the place but it isn't. As it was -7 when I woke up this morning and it shows no sign of getting above 0 so don't think I'll be fire it up today... or if I could.

Update....

Hi all... So here is where we are at on these two machines. The 412 has been pretty much holding it's own tho I have come to understand operations of these style of machines which we hadn't been doing and I will get to that shortly.

Regarding the E200... We pulled the radiator and took it to a shop. They did find it 30% plugged up in the bottom, cleaned it out and in the process found a leak which they fixed. We reinstalled it and we went from overheating upon the initial putting it under load to not overheating until about the 6th or 7th pass.

I have come to learn, I think, that these single engine pay scrapers are meant to be pushed when cutting... soooo... that's what we have been doing. Pushing them with the HD16 which has made a hige difference in stifling the overheating and allows for more consistent loading of the bowl.

Thebquestion I have... is am I on the right trak here or should these machines be able to function without being pushed. I will remind readers that we are dealing in both vegetated top soil and clay below that.

I don't think they should overheat unless under full load for extended periods and/or hot ambient temperature.

Elevator scrapers were/are designed as a work alone machine unless traction is a problem.
Did you check the transmission oil cooler and or the temperature? That maybe blocked and the hot air from that could cause the engine temps to go up.
