Wide Compatibility: Fits most mainstream manual transmissions like Eaton Endurant, Mack and Tremec.
Proven Technology: Backed by over 65 years of professional PTO R&D experience, balancing reliable performance and low operating costs.
Specifications
Applications
PTO489 provides stable and high-efficiency dual-flow hydraulic performance for industrial and mobile hydraulic systems requiring compact structure, reliable pressure, and continuous operation:
Fire and Rescue Trucks: Delivers consistent dual hydraulic flow for emergency equipment, rescue tools, and auxiliary systems to ensure reliable performance during critical operations.
Truck Cranes: Powers both lifting and slewing functions simultaneously, offering steady pressure and smooth oil flow for precise crane control.
Pumper Cleaner Trucks: Supports both water pumping and high-pressure cleaning circuits, meeting the demand for continuous, efficient dual hydraulic output.
Refuse Trucks: Provides independent hydraulic power for compaction, lifting, and dumping systems, ensuring dependable operation in waste collection and disposal tasks.
Factory&FAQ
PTO489 are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pumps from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 1-30days from the order date.
1. What is the PTO489 ?
PTO489 is a mechanical power take-off unit designed for manual transmissions. It features one-piece cast iron housing, 8-bolt direct mounting and heavy-duty tapered bearings, delivering 250 Lbs-ft torque. With rich configurations, it fits most mainstream manual transmissions for heavy-duty vehicles.
2. What makes the PTO489 different from standard Hydraulic PTO?
PTO489 adopts mechanical shift structure, different from regular hydraulic PTOs.
It uses one-piece cast iron housing and tapered bearings for larger load capacity.
8-bolt direct mounting cuts extra parts and lowers leakage risks.
It provides various speed ratios, output and shift options for wider compatibility.
3. What is the working pressure range of PTO489 mechanical PTO ?
The PTO489 is a mechanical PTO, not a hydraulic PTO.
It does not have a hydraulic working pressure range.
Its air shift control pressure is typically 90–120 psi (6.2–8.3 bar).
It delivers intermittent torque 250 lb-ft (339 Nm) for hydraulic pump driving.
4. Can PTO489 Hydraulic PTO replace other brands?
PTO489 is a mechanical PTO, not a hydraulic one.
It can replace most 8‑bolt mechanical PTOs (e.g., Chelsea 442/489, Muncie, Bezares) for Eaton Fuller, Mack, Tremec 8‑bolt transmissions.
Direct 8‑bolt mounting matches common SAE 8‑bolt openings; no adapter plate needed.
Interchangeability requires matching torque rating (250 lb‑ft), gear ratio, rotation, and output interface.
It is 100% interchangeable with original Chelsea 489/442 series in key dimensions and performance.
5. What hydraulic oil is recommended for PTO489 Hydraulic PTO?
PTO489 is a mechanical PTO, not hydraulic; it uses gear lubricant rather than hydraulic oil.
For its pneumatic shift control circuit: Use ISO VG 32–46 anti‑wear hydraulic oil (L‑HM).
Common grades: ISO VG 32 (cold climates) or ISO VG 46 (standard conditions).
Recommended specs: API GL‑4, meeting Parker HF‑1 / Eaton‑Vickers anti‑wear requirements.
For the PTO gear housing: Use SAE 80W‑90 gear oil.
6. What is the typical speed range of PTO489 Hydraulic PTO?
PTO489 is a mechanical PTO instead of a hydraulic unit.
Its applicable operating speed ranges from 500 RPM to 1000 RPM.
Stable power output is guaranteed within this speed range.
