Note: The roller brush pivot plate is properly seated when there is no resistance from the rubber grommet and it pivots freely. Note: Ensure that the idler-pulley assembly is installed on the bottom as shown in Figure 15 and Figure 16. 25. Apply 242 Loctite (blue) to the 2 bolts (5/16 x 5/8 inch) and use them to mount the brush plate to the roller brush bearing housing (Figure 15 and Figure 16). Torque the bolts to 20–25 N⋅m (15–19 ft-lb). 26.

4 Installing the 18-inch High Height-of-Cut Brush (Optional) g021352 Figure 27 22-inch cutting unit No Parts Required Procedure 1. Belt cover 41. Install the High Height of Cut Brush, Part No. 121-3199 when cutting above 2.5 cm (1 inch) height-of-cut (i.e., 5 or more spacers installed below the side plate pad). Lubricate the grease fittings on each of the roller brush bearing housings with No. 2 general-purpose, lithium-base grease (Figure 28). 1.
g020301 Figure 31 1. Non–drive bearing housing 3. Brush shaft g020302 2. Excluder seal 3. Remove the 2 J-bolts and nuts (Figure 32). 4. Slide the existing brush off the brush shaft (Figure 32). 5. Loosen the 2 bolts, washers, and nuts securing the drive bearing housing to the bearing housing mounting bracket (Figure 32). 6. Slide the high height of cut brush onto the brush shaft (Figure 32). 7. Clamp the brush onto the shaft with the 2 J-bolts and nuts previously removed (Figure 32).
Maintenance Note: Put a 1/2 inch wrench on the roller brush shaft flats to keep it from rotating. 1. Ensure that the brush is parallel to the roller with 1.50 mm (0.06 inch) clearance to light contact. 2. Grease fittings every 50 hours or after every washing. 3. When replacing roller brush, torque J-bolts to 2 to 3 N⋅m (20 to 25 in-lb). 4. When replacing the brush shaft driven pulley, torque the nut to 36 to 45 N⋅m (27 to 33 ft-lb). 5.
• Start the belt on the driven pulley (Figure • 21). Use a 9/16 inch deep-well socket to rotate the brush assembly and guide the belt onto the driven pulley (Figure 36). 2. Insert a long-handled pry bar (recommended 3/8" x 12" with screwdriver handle) through the back of the cutting reel, closest to the side of the cutting unit that you will be torquing (Figure 37). 3. Place the pry bar against the weld side of the reel support plate (Figure 37).
Restraining the Reel for Installing Threaded Inserts 1. Insert a long-handled pry bar (recommended 3/8" x 12" with screwdriver handle) through the front of the cutting reel, closest to the side of the cutting unit that you will be torquing (Figure 38). 2. Place the pry bar against the weld side of the internal cutting reel reinforcement (Figure 38). Note: The pry bar should contact a blade at the front, the reel shaft, and a blade at the back of the back of the reel, locking it in place.
