BROCE FMJ470

BROOM WAFER REPLACEMENT

The standard Broce Broom core uses 10” x 32” at wafers and metal spacers. The

standard eight-foot core requires approximately 54 wafers and 53 metal spacers

(this will vary by wafer manufacturer and type of end-caps ordered on broom). The

amount of wafers required as well as specic installation instructions may be ob-

tained from the wafer manufacturer.

Do not try to readjust the motor mount unless it becomes damaged or otherwise

unserviceable. The alignment of this mount is preset at the factory. If it does

become necessary, refer to the alignment procedures in the MAINTENANCE

section of this manual.

• With the core resting on or near the ground, remove the bolts securing the pillow block

bearing to the core support frame.

• Pull the core to the right side of the machine until you feel the splined hub come o󰀨 the

shaft. At this time, the core will be close to or touching the right support arm.

• Angle the core toward the rear of the machine and slide it out from under the sweeper.

• Clean the spindle from the lock ring out using an emery cloth or sandpaper.

• Loosen the setscrew and remove the lock ring and pillow block bearing.

• Remove the spindle and install the Broce Core Service Ring in its place.

• Remove the end cap from the drive end of the core.

• Raise the core support frame and slide the rebuilt core under the sweeper. The core

will have to come in from an angle in order for it to be started over the motor mount.

Once the core has been started onto the motor mount, swing the right side under the

right support frame.

• Lower the support frame slowly until the motor mount is centered in the core.

• Using a back and forth twisting motion, pull the core onto the splined shaft.

• Install the pillow block bearing on the right side of the core using the original mounting

bolts.

• Raise the core. Slide the core to the left as far as it will go. Using a pry bar, slide it

back to the right until the bolts on the end cap will clear the hydraulic hose ttings.

• Install the lock ring on the spindle securely. This lock ring is all that maintains core

alignment.
