What does it mean when your final drive is leaking?
What does it mean when your final drive is leaking?
A parts specialist is waiting to help! If the leak is on the planetary side of the final drive it will be gear oil which is thicker. This type of leak usually drips from the inside of the track. You will probably have grinding noises along with the leak and the travel motor could lock up.
What causes hydraulic fluid to leak from final drive?
A clogged case drain filter can cause the internal seals to blow and the final drive to start leaking hydraulic fluid. The presence of a thicker fluid would point to leaking gear oil, which indicates the leak is on the planetary side of the final drive (where the gear system is located).
How much oil is in the front of the final drive?
Note, however, that on average there are about two quarts of gear oil contained in the front of the drive: a very large quantity of fluid would indicate a problem with the hydraulics rather than on the planetary side.
What does it mean when your track Drive is leaking oil?
You will probably have grinding noises along with the leak and the travel motor could lock up. If your track drive is leaking oil near where the sprocket mounts, this will probably indicate that the mechanical face seal – also known as the floating face seal or duo-cone seal – has failed.
Why is there a leak in my final drive?
If your leak is indeed hydraulic fluid, then you either have a hose leak or a problem in the hydraulics section of your final drive. One of most common causes of a hydraulic leak is a clogged case drain filter.
A clogged case drain filter can cause the internal seals to blow and the final drive to start leaking hydraulic fluid. The presence of a thicker fluid would point to leaking gear oil, which indicates the leak is on the planetary side of the final drive (where the gear system is located).
Why is gear oil leaking from my final drive?
Well, hydraulic fluid is going to have a much thinner consistency than gear oil, so if the leak is a thin fluid then it is likely hydraulic fluid. A final drive only contains about two quarts of gear oil on average, so if there is an excessive amount of fluid leaking then, again, it is going to most likely by hydraulic fluid.
What happens when you blow the oil seal on a final drive?
As this pressure builds up, it will blow the oil seal and allow that hydraulic fluid–which is under high pressure–to enter the gearbox. This is a serious problem, and if not addressed it can devastate your final drive. And by “devastate” we mean things like crack the cover or blow it off at high speed.
