advantages

Engineering Vibration-Resistant Wear Resistance, Stable Walking Performance: Core friction pairs adopt alloy reinforcement and secondary stress relief process, effectively resisting frequent vibration and alternating load wear during equipment walking, suppressing internal leakage growth and maintaining stable low-speed high-torque walking output for a long time.
High Cost-Performance, Reduce On-Site Maintenance Loss: Support flexible single-piece replacement for local partial wear and full rotating group kit replacement for overall motor aging performance decline. Avoid the high cost of integral travel motor replacement and greatly reduce equipment maintenance and construction downtime losses.
Full Accessory Coverage, One-Stop Travel Motor Overhaul: Complete coverage of all core rotating group wearing parts and medium-pressure sealing vulnerable parts, fully adapting to daily maintenance, fault repair and full overhaul of JMF29 travel motors, realizing one-stop professional supporting maintenance.
Strict Factory Inspection, Uniform Batch Quality: Each batch of spare parts undergoes precision dimensional verification, flatness testing, hardness sampling and medium-pressure simulation tests to ensure consistent batch quality and stable walking performance after motor repair.
Medium-Pressure & Temperature Resistance, Adapt to Frequent Travel Operation: Customized material formula adapts to frequent start-stop and vibration operation characteristics of engineering travel systems, effectively delaying seal aging and component fatigue, extending the overall service life of repaired travel motor.

FAQ

Q1: What core walking faults can JMF29 pump spare parts solve?
A: It thoroughly solves common travel faults caused by long-term vibration and impact wear of JMF29 travel motor, including excessive internal leakage, insufficient walking driving force, weak climbing ability, slow hydraulic response, unilateral slow travel, walking jitter, abnormal operating noise and oil seepage & leakage.
Q2: What equipment does JMF29 spare parts fit?
A: Specially applicable to 6–8 ton small and medium-sized excavators of various brands, perfectly matching original JMF29 travel motor assembly and supporting drive system parameters.
Q3: How to choose single parts or full overhaul kit?
A: For motors with short service life and only individual partial wear or slight speed difference, select single-piece replacement; for motors with long-term high-frequency walking operation, obvious power attenuation and overall component aging, replace the full rotating group kit to restore complete original walking performance.
Q4: What are the key overhaul points for JMF29 travel motor?
A: Thoroughly clean internal oil passage impurities and worn powder, replace all aging medium-pressure seals, strictly control friction pair assembly clearance and flatness fitting, and conduct no-load and load walking test debugging after assembly to ensure synchronous left and right speed and stable driving.
