What Causes Axle Leaks in the Gehl 5635?
Axle leaks are a fairly common issue with heavy equipment, and they typically occur when seals or gaskets wear out, break, or degrade over time. In the case of the Gehl 5635, these leaks are generally associated with hydraulic fluid or axle oil. Several factors contribute to axle leaks:
1. Worn or Damaged Seals
Seals in the axle housing are designed to prevent fluid from leaking out of the housing. Over time, these seals can wear out or become damaged due to regular usage and exposure to the elements. When seals fail, hydraulic fluid or axle oil may leak, leading to a loss of lubrication and potential overheating of the components.
Preventive Solution:
Contaminants such as dirt, dust, and debris can enter the axle housing if seals or covers are compromised. When contaminants enter, they can degrade the lubricating oil and cause increased friction within the axle, which leads to faster wear of the seals and gaskets. This, in turn, can result in fluid leakage.
Preventive Solution:
Overfilling the axle housing with oil can cause excess pressure on the seals and gaskets. This excessive pressure can push the oil through weak spots in the seals, causing leaks. Additionally, overfilled axles can lead to increased wear on the bearings and other moving parts due to the excess fluid.
Preventive Solution:
With constant use, the axle assembly and its components naturally wear down. Parts such as bushings, bearings, and seals can degrade over time, even with proper maintenance. The result is often a slow but steady leak that can go unnoticed until significant fluid loss occurs.
Preventive Solution:
Inadequate or improper maintenance can accelerate wear and lead to fluid leaks. For example, failing to change axle oil at regular intervals or using the wrong type of oil can lead to seal deterioration and eventually cause leaks.
Preventive Solution:
Identifying an axle leak early can help prevent more serious damage to your Gehl 5635. Some of the signs of an axle leak include:
If you’ve identified an axle leak, timely action is needed to prevent further damage. The repair process involves several steps:
