Rear Roller Brush Service Tips

Product: Reelmaster 5010 Series Roller Brushes May 14, 2007

Affected Units:

All 5010 Series Roller Brushes

Models:

03663

03683

Serial Numbers:

Any

Situation:

Due to the nature of the Rear Roller brush, durability and belt life is highly dependent on setup

procedures and accuracy of adjustment. Failure to follow Operator's Manual instructions or improper

adjustment can result in reduced belt life and other service complaints related to durability. Most of the

complaints received to date have been traced to setup or adjustment issues.

Instructions:

The following areas are critical to long term belt life and overall durability of the Roller Brushes.

Verify these items as part of your setup process and any time service is performed on the Rear

Roller Brush.

1. Verify that the brush Mounting Bracket is mounted directly to the top surface of the

cutting unit Side Plate flange. There should never be spacers between the Side Plate

flange and the Roller Brush Mounting Bracket. Any unused Spacers should be at the

top of the assembly. (figure 1)

. Verify the Brush Plate is correctly inserted into the rubber grommet on the drive assembly. The Brush Plate should naturally set nestled against the drive assembly. If the Brush Plate does not remain fully engaged with the drive assembly as pictured below (figure 2): a. Verify the Brush Plate is fully inserted into the grommet. b. Loosen Brush Mounting Bracket Nuts (both sides). c. Adjust Brush Mounting Brackets by pushing in and forward until the Brush plate remains fully inserted into the grommet.

. Verify the Idler Stop is at the bottom of the slot after belt tensioning. Push the Brush bearing housings forward prior to tightening the hardware. This ensures proper pulley spacing so that the Idler Stop will not be lodged at the bottom of the adjustment slot, resulting in an over tensioned belt (figure 3). a. Loosen the hardware securing the Bearing Housing. b. Slide the Bearing Housing forward in the mounting holes. c. Retighten Bearing Housing hardware. d.

. Verify Pulleys are aligned properly. This should be done as part of setup and any time service is performed on the Roller Brush Assembly. a. Release Idler and remove belt. b. Lay a straight edge across the outer face of the Drive Pulley. Do not contact any other pulley (figure 4). c. Use the straight edge to verify position of Driven Pulley. The outer face of the Driven Pulley should be inline within ± .032 (shim thickness) of straight edge (figure 4). d.

. Verify the tangs (teeth) of the Drive Pulley are fully seated. Apply Loctite 242 or equivalent to the Bolt threads and torque to 27 to 33 ft-lbs (37 to 45 N-m) (figure 6).

. Verify Belt is tensioned properly (Figure 7). a. Loosen Idler Pulley Nut. b. Use SPRING FORCE GAUGE to apply 15 lbs of vertical force to the idler pulley bracket. Note: A used belt (having run more than two hours) should have 10 lbs of force applied. c. While holding tension, tighten Idler Pulley Nut.
