Case Drain Failure On Excavator Drive Motors: How To Avoid Catastrophic Failure
What is case drain failure?
The case drain line connects the hydraulic fluid reservoir to the final excavator drive motor. Case drain lines function to carry internal leaking fluid away from the excavator drive motor such as the one on an
IHI 28N. If this line becomes clogged or otherwise malfunctions, it can cause catastrophic failure to your IHI 28N excavator drive motor.
One of the first steps to ensure the case drain line functions properly is to regularly check and replace the case drain filter when needed. If your machine is equipped with a case drain filter and it isn't regularly checked and replaced, it can cause a massive build-up of pressure, which can lead to a catastrophic cascade of failures within your system.
Blown pistons, cracked plating on the
mini excavator drive motor, blown seals, and damage to the bearings are just some of the possible damages that could occur. In fact, 90% of premature final drive motor failures on Bobcat brand machines are due to a clogged case drain filters.
In addition to keeping an eye on the case drain filters, in order to keep the excavator drive motor performing at the highest standard, it is recommended that the final drive gear oil should be checked about every 100 hours of operation or once a month, whichever comes first. Keeping the final drive gear oil fresh will help increase the longevity of your equipment.
Remember that maintenance is key
Whether you're working with heavy equipment or a small machine, maintenance is crucial to keeping everything running efficiently. Don't let yourself become another statistic of blown excavator drive motors.
Doing regular maintenance on your machines can save you thousands of dollars in parts, labor, and downtime. The longer your excavator drive motor
is out of commission, the more revenue you miss out on.
