While repairs were underway, the quarry operator called PIRTEK Bridgeport-Chico to evaluate the machine’s hydraulic system. PIRTEK identified an opportunity to address aging hydraulic hoses while the equipment was already accessible for transmission repairs.
An unexpected transmission failure took a Komatsu WA900 wheel loader out of production at a North Texas quarry serving the Bridgeport-Chico area. But instead of simply repairing the transmission and returning the machine to service, the quarry operator used the downtime to address another critical maintenance need: the machine’s aging hydraulic hoses.
While transmission repairs were underway, the operator called PIRTEK Bridgeport-Chico to evaluate the hydraulic system. With major components already accessible, the timing created an opportunity to replace worn hydraulic hoses before they failed in service.
The result: PIRTEK completed a Komatsu WA900 hydraulic hose replacement during the existing repair window, replacing 37 worn hydraulic hoses and reducing future failure risk without requiring additional downtime.
The Challenge: A Critical Machine Down at a Busy Quarry
Large wheel loaders are essential to aggregate operations. When one goes offline unexpectedly, every hour of downtime can affect production, scheduling, and operating costs.
With the transmission already removed, critical hydraulic components were far more accessible than they would be during normal operation. The quarry used the existing repair period as a chance to inspect the hydraulic system and identify potential issues before the machine returned to production.
The PIRTEK Solution: Hydraulic Hose Replacement During Existing Repairs
PIRTEK technicians provided on-site hydraulic hose replacement using a fully equipped Mobile Service Vehicle capable of fabricating, tagging, and installing hydraulic hose assemblies directly at the quarry.
Many equipment owners assume hydraulic hose work must go through the original equipment manufacturer (OEM). However, PIRTEK is authorized to perform hydraulic hose replacement across all major equipment brands, including Komatsu, CAT, John Deere, Volvo, Case, and more.
During the inspection, PIRTEK identified 37 hydraulic hoses showing significant wear and an increased risk of failure. Because the transmission repair had already created access to critical hydraulic components, technicians fabricated, tagged, and installed replacement hose assemblies on-site. Completing the hydraulic hose replacement during the same maintenance period allowed the quarry to address a future failure risk without scheduling a separate equipment outage.
Turning an Emergency Repair Into a Preventive Maintenance Opportunity
Unplanned downtime is unavoidable, but it can also create opportunities to complete maintenance that may otherwise require another service interruption. By combining hydraulic hose replacement with the transmission repair, the quarry improved equipment reliability without extending the repair timeline.
By completing hydraulic hose replacement while the Komatsu WA900 was already undergoing repairs, the quarry was able to:
• Address worn hydraulic components before they failed during operation
• Avoid scheduling a separate maintenance event in the future
• Improve maintenance efficiency by completing multiple repairs during one service event
• Improve overall equipment readiness before returning to production
What began as an unexpected transmission repair became an opportunity to strengthen the machine’s hydraulic system.
The Result: Reduced Risk and Improved Equipment Reliability
Before the WA900 returned to production, PIRTEK Bridgeport-Chico replaced 37 hydraulic hoses that showed significant wear. Instead of putting the machine back to work with another potential failure point still in place, the quarry returned the loader to service with a stronger, more reliable hydraulic system.
By taking advantage of the existing repair window, the quarry operator:
• Reduced risk of hydraulic hose-related downtime
• Improved reliability of the Komatsu WA900 hydraulic system
• Maximized the value of an existing repair window
• Established a trusted partner for future hydraulic maintenance needs
This project demonstrates how unexpected equipment failures can become opportunities for proactive maintenance. With the right planning, an unavoidable repair can also help address additional maintenance needs, reducing future downtime and improving long-term equipment reliability.
