Hyster H25E Specifications
The Hyster H25E is a compact internal-combustion
forklift designed for light-to-medium industrial applications where
maneuverability, durability, and low maintenance cost are essential. With a
rated lift capacity of 2,500 lb (1,134 kg), the H25E occupies the smaller end of
the classic Hyster E-Series, well-known for its rugged steel construction,
simple mechanical systems, and ease of servicing.
Built during an era in which forklifts relied
primarily on mechanical and hydraulic functionality rather than complex
electronics, the H25E remains a sought-after model for operators who
prefer reliability and straightforward maintenance.
The cushion-tire configuration and compact wheelbase make the H25E ideal
for indoor operations such as warehouses, retail distribution areas,
production floors, and dock-loading environments. The truck is
particularly valued for its stable mast design, predictable steering
response, durable powershift drivetrain, and strong availability of
replacement parts.
Its operator compartment provides good
visibility, easily accessible controls, and dependable hydraulic
response, making the H25E a practical long-term solution for businesses
seeking a simple, dependable industrial lift truck.
The H25E was produced with several small industrial
engines depending on year and market.
Common engine types include:
- Continental TM20 or TM27 gasoline industrial engines
- GM 2.5-L LPG/gasoline engine (some later variants)
- Mazda 2.0-L LPG industrial engine (market-specific)
Engine Characteristics:
- Displacement range: approx. 2.0-2.7 L
- Rated power output: approx. 30-45 hp (22-34 kW)
- Rated torque: approx. 60-85 lb-ft (81-115 Nm)
- Idle speed: approx. 650-750 rpm
- Maximum governed speed: approx. 2,400-2,600 rpm
- Fuel type: gasoline or LPG
- Ignition: mechanical distributor with points and coil
These engines emphasize longevity, mechanical simplicity, and strong low-end
torque appropriate for slow-speed industrial movement.
Lubrication System
The H25E uses a full-pressure wet-sump lubrication system.
- Oil capacity: approx. 3.5-4.5 L (3.7-4.8 qt)
- Oil pump: gear-type, crankshaft-driven
- Oil pressure: approx. 20-30 psi (138-207 kPa) at idle; 45-60 psi (310-414 kPa)
at rated RPM
- Recommended oil: SAE 10W-30 or 15W-40 depending on ambient temperature
A replaceable spin-on full-flow oil filter is standard. Due to dusty
environments, more frequent oil changes may be required.
Cooling System
Cooling is provided by a liquid-cooling system.
- Coolant capacity: approx. 6-7.5 L (6.3-7.9 qt)
- Cooling system pressure: approx. 12-15 psi (83-103 kPa)
- Thermostat opening temperature: approx. 82°C (180°F)
- Water pump: belt-driven centrifugal
- Fan: engine-driven mechanical fan
Radiator airflow must remain unobstructed for proper cooling, especially in
indoor operations with limited ambient ventilation.
Transmission
The H25E typically uses a compact single-speed powershift transmission.
- Transmission type: hydraulic powershift
- Forward travel speed: approx. 8-10 mph (13-16 km/h)
- Reverse travel speed: approx. 8-9 mph (13-14 km/h)
- Transmission fluid capacity: approx. 4-6 L (4.2-6.3 qt)
- Recommended fluid: ATF Dexron II/III
Operators benefit from smooth directional transitions due to hydraulic clutch
pack actuation.
Drive Axle
The front drive axle is a cast-steel industrial axle.
- Lubrication capacity: approx. 1.5-2.0 L (1.6-2.1 qt)
- Lubricant: SAE 80W-90 gear oil
Brakes
Braking is handled by an industrial drum brake system.
- Service brakes: hydraulic drum brakes mounted at the drive axle
- Parking brake: mechanical hand-lever drum brake
The electrical system is a simple 12-volt architecture.
- Battery capacity: approx. 55-70 Ah
- Alternator/generator output: approx. 35-55 A depending on year
- Starter motor: approx. 1.4-1.8 kW
- Ignition: mechanical distributor (gasoline) or LPG ignition module
Wiring is straightforward and service-friendly, with minimal safety interlocks
compared to later models.
The H25E is built on a rigid, welded-steel chassis
optimized for indoor maneuvering.
Drive Configuration:
- Drive wheels: front
- Steering wheels: rear
- Drive mode: 2WD
Tire sizes:
- Front: approx. 18x6x12
- Rear: approx. 15x5x11
Non-marking options exist for clean manufacturing environments.
The truck uses rear-wheel hydraulic steering.
Steering:
- Steering type: hydrostatic orbitrol
- Steering pump flow: approx. 5-8 L/min (1.3-2.1 gpm)
- Turning radius: approx. 1.7-1.9 m (67-75 in)
- Rear axle: oscillating, center-pivot type
Hydrostatic steering provides smooth directional control even with
continuous load cycling.
Hydraulics power lift, tilt, and optional attachments.
- System pressure: approx. 2,000-2,300 psi (138-159 bar)
- Pump type: engine-driven gear pump
- Pump flow: approx. 18-25 L/min (4.7-6.6 gpm)
- Hydraulic tank capacity: approx. 20-25 L (21-26 qt)
- Recommended fluid: ISO VG 32 or VG 46 hydraulic oil
Lift and tilt cylinders are heavy-duty double-acting types for stable load
control.
