W2033318
1. Crankshaft Gear
6. Power Steering/Fuel Pump Gear
2. Double Idler Gear
7. Air Compressor Gear
3. Adjustable Idler Gear
8. Oil Pump Gear
4. Camshaft Gear and Damper
9. Power Take-Off Gear (Optional)
5. Auxiliary Idler Gear
10. Timing Gear Plate
The timing gears are located at the rear of the engine. Backing up the gears is a plate:
a 6 mm (1/4 inch) thick steel sheet attached to the cylinder block.
The advantages of this configuration are more precise timing, fewer components
and lower noise levels.
The power steering/fuel pump gear, the air compressor gear and the PTO gear are not
timing gears. The pump and compressor gears fasten to their respective components.
The pump gear is driven by the auxiliary idler gear. The compressor gear is driven
by the double idler gear.
The double idler drives the adjustable idler and the gear used to drive the power
take-off, if so equipped. This is part of the "REPTO-Ready" feature. A PTO unit with
drive gear is substituted for a cover on the flywheel housing.
The camshaft gear fastens to the hub on the end of the shaft. A vibration damper also
attaches to the hub outboard of the gear. Teeth on the damper actuate the camshaft
position sensor. The gear is driven via the adjustable idler.
