I found a burst hose on a 7020LBH tractor and wanted to inform folks who have any of these tractors to take note. All 6000 and 7000 series tractors both loader or loader back hoe models all have the same configuration of the return oil flow to the oil cooler. This is the hot expended oil coming from all hydraulic components of the tractor. There is a steel manifold where the return oil lines are connected, the output of which is connected to a rubber hose, P/N C32148. The hot return oil passes thru this hose and into the oil cooler. This hose is molded with a 90 degree bend to connect it to the oil cooler and with a slight bend connects to the output of the return oil manifold. The slight bend is where the hose can fatigue and split. The oil passing thru this hose can get up to 200F as it is return oil. This hose is located behind the steering tower removable panel in the left hand side, fairly easy to replace. However, the oil in both the oil cooler and the hyd oil reservoir will drain out. A quick way to drain the system is to remove the hyd oil filter and carefully catch the oil or with an oil extractor, suck out the oil in the reservoir. But no matter what, oil will come out when this hose is removed so be prepared for this. LBH tractors have the back hoe support under this area and the oil will drip onto this.
Another 7020 point of info is that being all wheel drive, both drive motors turn all the time the tractor is moving as they are connected in a series hydraulic loop to the travel control valve. The front drive system is engaged with an electric clutch to the front drive motor. Never operate a 7020 in high range all wheel drive, low range only!!!!:cool:
