John Deere 6120 Transmission Problems Problems

John Deere 6120 Transmission Problems. I have been with a John Deere 6120 tractor for 3 years and there is a problem with the gearbox. I tried to fix the problem on my own, but when I disassembled the gearbox I saw dirt forming there. What to do so that the dirt does not go to?

Repair of John Deere machinery and equipment will certainly be necessary if the working fluids are not replaced on time. Old oil or any other bonding material cannot provide optimal protection to engine, gearbox, and transmission components, leading to increased stress on components. Subsequently, they simply fail. Smoke from the engine, suspicious knocks, reduced equipment power all heralds an imminent repair. The drive will simply stop and the tractor, combine or other special equipment will not work. It will be necessary not only a complete disassembly of the engine, but also the search for suitable parts. And all due to the fact that changing the oil, filters, etc. it was not done on time.

No matter how high the quality of the special equipment is, one way or another it breaks down and needs to be repaired. This can be avoided through regular maintenance and diagnosis, but even then there is no total certainty that the machine will not fail.

The gearbox is one of the most vulnerable places on special equipment. During operation, due to friction inside the gearbox, dirt is formed, which adversely affects the integrity of the internal components. If maintenance, oil or filter changes are not timely, the gearbox fails.

Also, the gearbox may stop working as a result of normal wear and tear. In particular, its replacement or repair may be necessary:

  •  friction discs;
  • pumps; gear pistons;
  • control solenoids;
  • torque converter;
  • helmets, etc.

To fix most of these problems, it is necessary to completely disassemble the gearbox. It is very difficult to do it yourself, it is easier to contact the service center.
