Hello! The gearbox is full of oil, it is squeezed through the filler plug. Replaced the filter and oil. The problem remained. Working hours 17000.
In the diagnosis of this and other modern machines, we use the most advanced method - observation. So, in the course of this method, we found out that our tractor began to produce oil itself. We searched all catalogs by spare part numbers to order and install "udder" and receive additional income. We also assume that since she started producing oil, our tractor was fertilised by some other and now he is pregnant and will give birth...
Seriously, we found out that the oil gets into the box from the engine... But there are no diagrams of these units to find out the supposed place of contact...
We have thought about doing similar, but with diesel getting into engine oil. Put a tap on sump, drain the excess and sell the oil.
We assume it. We think it's impossible...
I do not have experience with Komatsu, but experience says the rear main crank seal or oil coolers is the logical place to start. Are you sure its engine oil? The engine would have to be loosing litres of oil a day to be noticed. I have seen hydraulic oil and coolant entering into the transmission.
2 liters of engine oil per shift. That's what makes me suspicious. The oil that flows out is very black. We changed it twice in the box, so we cleaned the box a little. Hydraulic oil is clean... In general, the scheme has not yet been found, while we are discussing, assuming, collecting information... Opinions are divided, into engine and hydraulic...
Well, it gets into our bridges on the old John Deere, we put the hose on it back into the water tank so that it wouldn't spill on the ground. On CAT, it got into the front axle. But in the gearbox...
Translation difficulties. I apologize. I'm talking about hydraulic oil.
Experience is a priceless thing! Today we discussed with a friend and assumed how exactly the coolant can get into the transmission and where exactly. When you have enough free time, tell us about it.
Sounds like rear main has gone it's a wet converter housing due to the PTO, engine out will be quickest and easiest way to carry out the repair, get a rear main with a speedisleeve
What machine is that on cliffy
