Design Features
The 14E featured hydraulic-boosted gear controls, a design that distinguished it from its predecessor, the 12F. This setup provided operators with enhanced control and responsiveness. Additionally, the blade lift gears were mounted above the front wheels, a configuration that improved visibility and accessibility for maintenance.
Common Maintenance Issues
A prevalent issue reported by operators is the failure of the planetary gears within the gearbox that controls the blade's elevation. These gears, often referred to as "spider gears," can suffer from broken teeth due to wear and tear. For instance, one operator noted a broken tooth on one of these gears, highlighting the importance of regular inspections and maintenance to prevent such failures.
Parts and Maintenance
Replacement parts for the 14E, such as the planetary gears, can be costly, with prices exceeding $400 each. However, operators have found success sourcing more affordable options through various suppliers. It's advisable to consult with reputable dealers and consider aftermarket parts to manage maintenance costs effectively.
Market Presence and Availability
The Caterpillar 14E motor grader has seen a resurgence in interest among collectors and operators of vintage machinery. Listings for used models, such as a 1968 unit, have been available on platforms like Ritchie List, indicating a niche market for these classic machines.
Conclusion
The Caterpillar 14E motor grader remains a significant model in the history of heavy equipment. Its robust design and powerful engine have allowed it to endure over decades, continuing to serve in various applications. For those interested in vintage machinery, the 14E offers a blend of historical value and practical functionality.
