Removing and Replacing the Wheels
The Wheels on the DR 16.50 FTP PRO Rapid Feed Chipper are pneumatic and have pressed in Bearings
for easy transport. With use, tires or Bearings may need replacing. The following procedures will
explain the replacement procedures.
Tools Needed:
• 5/32" allen wrench
• Fine Tooth File
• Jack
1. Jack up the side of the Chipper just until the
Pneumatic Wheel is off the ground.
2. Loosen the Set Screw with a 5/32" allen wrench and
remove the Locking Collar (Figure 45).
3. Remove the Pneumatic Wheel from the Axle.
NOTE: There is a spacer behind the wheel that must remain
on the Axle when the Pneumatic Wheel is replaced.
NOTE: File off the Set Screw marks in the Axle if Wheel will
not slide on.
4. Install the Pneumatic Wheel onto the Axle and against
the Spacer with the Valve side out.
5. Install the Locking Collar onto the Axle against the Wheel and tighten the Set Screw with a 5/32"
Allen Wrench.
6. Check the Pneumatic Wheels for proper air pressure of 38 psi maximum in each tire (see Chapter
3).
Removing and Replacing the Clutch
The design of the Clutch on your machine is for rugged, dependable service; however, it is important to
understand the limitations of a Clutch. The Clutch design is to provide load free starting of the Engine,
and slippage under excessive overloading of the driven application. These features help protect the
Engine from damages such as broken crankshafts and starters. The Shoes and Springs on the Clutch
are normal wear items. If you notice decreased performance of the Clutch, check and replace it if
necessary.
SHUT DOWN THE ENGINE, WAIT FOR ALL MOVING PARTS TO COME TO A COMPLETE STOP,
REMOVE SPARK PLUG WIRE, DISCONNECT THE NEGATIVE BATTERY CABLE, THEN WAIT 5 MINUTES
BEFORE PERFORMING ANY MAINTENANCE PROCEDURE OR INSPECTION ON THE CHIPPER.
