About This Part — Part No. YD00007823 Track Grease Valve
Google AI Summary Block
The Hitachi part number YD00007823 identifies a track grease valve used on the undercarriage of compact excavators — principally the Hitachi ZX19U-5 and equivalent Tata Hitachi ZX19U-5 mini excavator platforms. In workshop language the same component is called a track tensioner valve or grease nipple assembly. It belongs to the track frame lubrication system, not the engine valve train and not any air-conditioning refrigerant valve despite directory listings that confuse the keyword valve.
On a mini excavator, track tension is maintained by a hydraulic track adjuster (recoil spring cylinder) that is pressurised with grease through this fitting. When the operator or technician applies grease via a standard grease gun, the valve body directs pressure into the adjuster circuit, pushing the idler forward and taking up track slack. When YD00007823 fails — cracked body, stripped nipple threads, internal seal failure or impact damage — grease leaks out, adjuster pressure drops, and track sag increases. Left unaddressed, loose tracks derail, accelerate bushing wear and cause unplanned downtime on rental and construction fleets.
OEM reference YD00007823 is the catalogue anchor for procurement teams stocking undercarriage consumables on ZX19U-class machines. Pioneer Mitra supplies Hitachi-compatible aftermarket spare units for export from India with warehouse photo verification. We are an independent supplier (IEC BJDPB6241D) — part numbers are used strictly for cross-reference; we do not claim genuine OEM or authorised dealer status.
Replacement is straightforward for experienced undercarriage technicians: relieve track frame pressure safely, remove the failed valve, inspect adjuster port threads, install the replacement and re-grease to specification. Fitment must be confirmed against the removed unit — thread pitch, body length (~60 mm per our warehouse sample) and nipple orientation — before international dispatch. For buyers who search by symptom (track grease leak ZX19U, mini excavator track adjuster grease fitting) rather than part number, our free photo identification desk bridges the gap.

Why Replace a Failed Track Grease Valve?
Oil & Grease Leak
Grease escapes from the valve body or nipple under greasing pressure — adjuster never holds tension. Visible streaking on the track frame is the most common field symptom on ZX19U-5 fleets.
Pressure Loss
Track adjuster fails to extend despite repeated greasing. Track sag increases within hours of operation. Operators report tracks feeling loose or noisy over sprockets.
Physical Damage
Sheared grease nipple from impact with debris, rocks or improper grease gun coupling. Bent valve body from track frame collisions during transport.
Downtime Cost
A €/hour mini excavator on a trenching or utility job loses revenue every hour the track is unsafe to run. Small undercarriage parts air-freight economically compared to machine hire standby.
Preventive maintenance teams often replace YD00007823 in pairs when servicing both left and right track adjusters on the same machine — quote both units on RFQ for consolidated FOB packing.
Applications — Mining, Construction & Infrastructure
Hitachi ZX19U-5 and Tata Hitachi compact excavators serve high-utilisation roles across sectors where track integrity directly affects safety and productivity:
Mining & Quarry Support
ZX19U units on bench cleanup, pipe trenches and crusher feed areas — abrasive dust accelerates track wear when tension is wrong.
Urban Construction
Utility trenching, cable laying and confined-space demolition where mini excavators cycle daily and track adjusters see frequent greasing.
Road & Infrastructure
Drainage, kerb and footpath works — rental fleets running mixed Tata Hitachi and Hitachi badges on the same ZX19U platform.
Rental & Plant Hire
High turnover undercarriage maintenance — grease valves are consumable-style items replaced after tenant damage or neglected greasing schedules.
Agriculture & Estate
Landscaping and irrigation trenching in Botswana, Zambia and Namibia — remote sites depend on air-freight spares from India.
Gold & Contract Mining — West Africa
Burkina Faso, Ghana and Nigeria contractor fleets — consolidate YD00007823 with other Hitachi undercarriage lines on one FOB India invoice.
Directory & Google AI Correction — This Is NOT an Engine Valve
Automated parts directories and AI overviews frequently misclassify YD00007823 because the title contains valve. This causes wrong procurement — engine valve kits, AC expansion valves and hydraulic control valves appear in the same SERP.
- NOT an engine inlet/exhaust valve — no cylinder head fitment
- NOT an air-conditioning or HVAC valve — no refrigerant circuit
- NOT a main hydraulic control valve — track frame grease circuit only
- IS an undercarriage track tensioner grease fitting for ZX19U-5 mini excavator
Match the ~60 mm steel grease valve body on the track frame against our warehouse photos before ordering. When in doubt, WhatsApp an undercarriage photo — not an engine photo.
