Product Overview

Description

High-torque, low-emission diesel engine for strong performance in the toughest conditions

• Low vibration and noise levels


• Isolated with rubber mounts for a smoother operator ride


• Superior fuel economy


• High torque reserve for plenty of power and performance

Key features of the engine include:

• Economical, cast-in block cylinder design provides good cooling and long life.


• Liquid-cooled design provides more consistent operating temperatures than air-cooled.


• Fuel filter with replaceable element is provided.


• Indirect fuel injection uses a pre-combustion chamber to give the engine smooth and quiet operation.


• Full-pressure lubrication with full-flow filter lengthens engine life.
  
  
  
  • Engine wear reduced by ensuring proper lubrication, even when operating on hillsides or uneven terrain.
  
  
  • Oil filter helps keep oil clean for increased engine life.
  
  
  
  


• Aluminum alloy pistons with built-in steel struts are lightweight to reduce connection rod bearing loads and provide good heat-transfer characteristics.
  
  
  
  • Design permits tighter tolerances and neutralizes expansion of the piston, thereby reducing blow-by fuel and noise from the piston slap.
  
  
  • Higher top rings on the piston and a thinner head gasket greatly reduce the volume of unburned waste and increase combustion efficiency.
  
  
  
  


• Timing gears and injector drive gears utilize helical profile gears to help lower engine noise.
  
  
  
  • Gear teeth have a ”roll-off” profile, giving almost no clash, no noise, and no backlash.
  
  
  
  


• Glow plugs provide quick starts in temperatures down to -18°C (0°F)


• Key start and shutoff eliminate fuel shut-off knob; electric solenoid shuts fuel supply off immediately when key is turned off.
