TA91 8501
The 8501 Series transmission
system consists of an engine
mounted 21 or 23 inch type 8
torque converter, a 9 speed
coaxial power-shift transmission
and an advanced electronic control
system
Applications
• Oil Field Fracturing Rigs
• Mine Haul Trucks
• Anchor Hoists
• Large Cranes
• Special Purpose Equipment
Specifications
Maximum gross input power 3000 hp (2300 kW) at 2100 RPM
Maximum gross input torque 9500 lb-ft (12 880 N•m)
Maximum input speed 2100 RPM
Features and Benefits
• Increased performance: efficient gear train combined with electronic controls tailored to the
needs of the specific application to optimize machine performance.
• Ease of operation: available automatic shifting or manual power shift combined with shift inhibits
and interlocks simplify the operator’s job and allows for concentration on the job rather than the
powertrain.
• Reduced downtime: durable heavy-duty components combined with electronic controls which
prevent overspeed, shift shocks and reduce the effects of operator’s error, result in increased
machine availability and less wear and tear on other machine components.
• Safety: the control system looks after the transmission so the operator can focus on the operation
of the machine. Speeds and interlocks can be programmed to meet the needs of the specific
machine.
