977L overheating

[dwz28]

ser # 11K4646, loader over heats after about 15-20 minutes, rebuilt radiator, new turbo and air cleaner, new water pump and thermostat, cleaned oil cooler, new coolant, no bubbles in coolant, temperature good at high idle no load

Make sure the fan blades are all turned same direction.

Engine coolant temperature, transmission oil temperature, or both.?
Have you confirmed the temperatures registered by the gauge(s) using an infra red heat gun.?

If it is a reversible-blade fan, wot Nick said above.
if it is a pusher fan, is it installed the right way round.?

water temp is 210 when gauge gets to the red, fan pushes, pressure cap tested bad, going to try that, thx for the reply

have you used it at all, or did it overheat from day 1 with the rebuilt radiator?
I ask because the same vintage 977 I operated, we had to blow the dust out every other day. It did not tolerate work, as it was with most of us

fan pushes,

Do you believe that reversing the fan installation will make it suck, because that's not the case. The fan will push air out of the front of the hardnose whichever way it is installed. It will simply push less if it is installed backwards because it's not working efficiently.

Transmission temps are OK I take it.?

Got bigger problem now, blowing oil out the back of the converter

Have you taken a look at the transmission pump suction screen recently, or the small screen in the drain line from the converter housing at the converter end.?

 

[dwz28]

no

 

[Nige]

In that case checking the screens might be a good place to start.

 

[dwz28]

I will see if I can find them

I see you said no bubbles in the rad but have you checked for rad pressurizing from a bad head gasket ?

With that torque blowin oil sounds like scavenger pump not keepin up from possible screen stopped up or bad pump or sealing rings in torque. It cant get rid of it fast enough and thats whats heating the engine

I am checking the screens and replacing filters, what did I damage when oil blew out the rear of the converter?

Hard to tell at this point until you can find out why the oil blew out.

ok

changed the filter and cleaned the screens on the torque converter, now blowing fluid out the back of the converter

What did they look like ? Good Bad Ugly "need that Clint Eastwood music in the background"
Did you remove scavenger pump and open it up to see what it looks like while you had the screen out of torque and oil drained. If the suction screen was just stopped up with a bunch of trash you might have fixed the cause now you have to fix the blown seal. If you found steal or aluminum then its the ugly
