COLLECTOR BOX HOSE:
Tools Needed:
• Diagonal or wire cutter
•
Screwdriver or Nut Driver
1. Disconnect the Collector Box Hose from the Blower
Exit Elbow by loosening the Hose Clamp with a
Screwdriver or Nut Driver (Figure 41) and separating
the Hose from the Connector Fitting. Leave the loose
Clamp on the Fitting.
2. Tilt the Trailer Bed back for ease of access and cut the
Hose Support Tie Strap (Figure 42).
3. Remove the Hose from the inlet of the Centrifugal
Separator by grasping the Hose and unscrewing it,
clockwise (Figure 43).
4. Install the new Hose by turning the Hose
counterclockwise into the inlet opening of the
Centrifugal Separator. Turn the Hose in until about 4
or 5 of the hose ribs have entered the opening.
5. Lower the Tilt Bed, until locked in place, and slip the
remaining end of the Hose onto the connector fitting
on the Blower Exit Elbow.
6. Adjust the Hose length if the Hose sags away from the
Collector Box. Remove any excess Hose from the end
attached to the Blower Exit Elbow.
Tip: Determine the length of Hose to be removed by
holding the Hose tight beside the Connector Fitting.
Mark the place to cut the Hose. Cut the Hose spiral
with a diagonal cutter and then cut the Hose with a
razor knife.
7. Slip the Hose back onto the Connector Fitting, slide
the Hose Clamp up on the Hose, and tighten.
NOTE: Make sure that the Clamp is on the Blower side of
the raised rivet in the connector sleeve to prevent the
Hose from slipping off after you tighten the Clamp.
8. Replace the Hose Support Tie Strap with the new one
supplied with the replacement Hose (Figure 42).
Removing and Replacing the Blower Hoses
BEFORE PERFORMING ANY MAINTENANCE, SHUT OFF
THE ENGINE, ALLOW FIVE (5) MINUTES FOR PARTS TO
COOL AND DISCONNECT THE SPARK PLUG WIRE.
