AP2D14 Excavator Hydraulic Pump Complete Repair Kit
This full AP2D14 hydraulic pump overhaul kit contains all matching seals, gaskets, wear plates and plunger spare parts for mini excavator hydraulic system maintenance. Most overseas machinery repair customers search with fault words + model number, this repair kit targets all mainstream hydraulic component failures including hydraulic main pump, swing rotation motor, travel motor, multi-way distribution valve and engine hydraulic matching parts, to eliminate digger breakdowns without replacing the entire hydraulic assembly.
- Municipal road renovation, pipeline trenching and urban foundation excavation
- Farm land reclamation, orchard digging, irrigation ditch water conservancy project
- Rental excavator daily overhaul for independent machinery repair shops
- Mountain slope trimming, trail construction and small demolition jobs
- Port yard leveling, small cargo handling and logistics site ground finishing
- Rural housing foundation digging and small civil engineering construction
- Insufficient hydraulic pressure leading to weak digging power
- Pump body oil seal aging causing continuous external oil leakage
- Internal part wear triggering abnormal metal vibration & operation noise
- Pump flow disorder resulting in long-time working high oil temperature
- Plunger wear leading to pressure jitter and unstable digging movement
- Swing motor weakness: slow rotation speed under heavy digging load
- Swing vibration & sharp abnormal noise during left/right rotation
- Shaft oil seal damage causing swing motor hydraulic oil leakage
- Rotation stuck, unable to turn smoothly with bucket loaded
- Continuous swing operation causes whole hydraulic system overheating
- Walking weakness, slipping easily on muddy and wet construction ground
- Unilateral travel slow speed, excavator walking deviation during moving
- Travel motor gear wear noise and oil seal seepage failure
- Climbing slope stuck due to internal travel part abrasion
- Valve core internal leakage leading to bucket sagging and arm drifting
- Valve blockage causing digging movement jitter and unsmooth operation
- Long-hour construction leads to distribution valve overheating
- Engine load surge when hydraulic pump starts outputting pressure
- Engine power drop caused by AP2D14 pump internal blockage
A1: This overhaul kit solves AP2D14 main pump leakage, vibration noise, insufficient power, overheating; swing motor weak rotation, swing oil leak, stuck swing; travel motor walking slip; distribution valve arm drift and engine hydraulic matching load fluctuation faults for all mini excavators.
A2: Yes, all matched spare parts are fully equipped without extra accessories. It fits machinery repair stores, rental excavator operators and private digger owners for on-site construction maintenance.
A3: Compatible with AP2D14 main hydraulic pump, swing rotation motor, travel drive motor, multi-way distribution valve and engine hydraulic auxiliary matching parts of mini excavators.
A4: The main reasons are aging friction plates, worn sealing rings and internal gear abrasion of swing motor. This full repair kit replaces all worn core parts to eliminate swing jitter and abnormal sound completely.
A5: The kit includes full sets of oil seals, gaskets and wear-resistant sealing rings. Replace aging sealing accessories to stop oil seepage of main pump, swing motor and travel motor permanently.
A6: Definitely. After replacing worn internal pump and motor parts, hydraulic oil circulation and pressure output return normal, effectively lower oil temperature during long-time construction work.
