Bobcat 331 Mini Excavator Maintenance & Repair
Heath talks about the vital importance of keeping up the maintenance on your final drive in this informative video.
This final drive, taken from a Bobcat 331 mini-excavator, had begun to leak around the area of the face seal. Once it begins to leak, debris and contaminants can make their way inside the final drive and cause devastating damage, begin with massive bearing failure.
Most people’s instinct when they see a drive leaking is to simply refill whatever fluid is leaking out – whether its gear oil or hydraulic fluid.That doesn’t solve the problem, and won’t do anything to keep damaging contaminants from getting inside the final drive and eating away at key components.
Leaks should be addressed as soon as they are discovered, and long before they result in costly repairs and irreparable damage. If this drive had been repaired as soon as the leak was discovered, Heath states it would have cost about $600 and only have a one-day turnaround time. However, because the leak wasn’t addressed immediately the entire drive needs to be replaced – the damage was so bad it couldn’t be rebuilt.
