Maintenance & Engineer Tips: Avoid Common Mistakes and Extend Part Life

Our senior engineers, with over 35 years of oilfield and industrial experience, have compiled these practical tips to help you get the most out of our KHT5500 and KHT7625 parts and avoid costly mistakes—lessons learned from real-world maintenance scenarios:

• Inspect bearings (KHT7625-157, KHT5500-108) every 350 operating hours for wear, noise, and overheating. For INA3212 cylindrical roller bearings (KHT7625-157), use high-temperature lubricant (rated to 195°C) and check lubrication levels every 200 hours—using the wrong lubricant can reduce bearing life by 3,500 hours, which aligns with best practices for maintaining high-load bearings like the SKF 3212 series. If you notice unusual sounds or temperatures above 78°C, replace the bearing immediately.

• When installing fasteners (KHT7625-512, KHT7625-912, GB/T70.1-2000 M12X40), follow GB/T standards and use the correct torque settings: 70 ft.lb for 1/2″ hexagon socket cap screws and 65 ft.lb for M30 slotted nuts. Over-tightening can strip threads, while under-tightening can cause loosening—both lead to equipment failure in high-vibration environments like 6K-625 hydraulic motors.

• Clean hydraulic components (KHT7625-608, KHT7625-625) before installation to remove dirt and debris, which can cause valve sticking and leaks. For oil filled tee joints (KHT7625-625), check for leaks every 150 operating hours and replace Teflon washers (KHT7625-600) if signs of wear are present—leaks can waste 5-10 liters of hydraulic fluid per day.

• Store spare parts in a dry, temperature-controlled environment (7°C-28°C) to prevent corrosion and material degradation. Bearings should be stored in their original packaging until installation to protect them from dust and moisture, and jaw plates should be coated with anti-rust oil to prevent oxidation.

• Check structural parts (KHT5500-103, KHT7625-120) every 850 operating hours for cracks or deformation. A damaged support leg or base plate can cause equipment misalignment, leading to excessive vibration and wear—replace it immediately if any damage is found, especially for TQ245.7 support systems in uneven terrain.
