6.

Back off the hex nuts on the top and bottom tensioning bolts and rotate the tensioning bolts

counter-clockwise to allow approximately 38.1mm forward travel of the overhung load

adapter.

7.

Slide overhung load adapter and motor forward to remove tension from drive belt. Remove belt

from sprockets.

NOTE: 

Do not force the drive belt off sprocket flanges as belt damage can occur.

8.

Install new belt and position overhung load adapter and motor to approximate location when belt

was tensioned and reinstall the two back cap screws securing the overhung load adapter to the

mainframe. Reinstall the breather vent and adapter fitting to the overhung load adapter. Adjust

belt tension using cold tension specifications.

9.

The two tensioning bolts take a 3/8” allen wrench to adjust. Adjust the belt tensioning bolts

alternately until the proper tension is achieved. Turn the tensioning bolts clockwise to increase

belt tension and counter-clockwise to decrease belt tension.

10.

Retighten the cap screws securing the overhung load adapter to the mainframe.

11.

Recheck belt tension and adjust as required.

12.

Once the proper tension has been achieved, torque the cap screws securing the overhung

load adapter to the mainframe. Torque to 250 ft. lbs.

13.

Check to ensure the tensioning bolts are snug and then tighten the hexnuts.

14.

Install the housing seal plate so that it is against the overhung load adapter and tighten cap

screws.

NOTE: 

Housing seal plate is in place to minimize debris from entering the drive belt compartment and 

therefore reducing belt life.

15.

Install drive belt cover and maintenance access cover using existing hardware.

16.

If so equipped, reconnect the gauge hose if removed and reinstall the top right compartment

cover.

NOTE: 

Belt damage can occur if belt is too loose, too tight or if debris is present. Do not operate 

without drive cover installed.

SPROCKET REMOVAL AND INSTALLATION

TAPER LOCK BUSHING IDENTIFICATION AND ORIENTATION

When replacing sprockets, it is recommended to update both sprockets at the same time.

“JACK SCREW HOLES” 
“HALF THREADED HOLES”

REMOVAL

1.

Remove the drive belt. See “DRIVE BELT TENSIONING AND/OR REMOVAL”

2.

Loosen the taper lock assembly (bushing) in the sprocket by removing all mounting screws.

3.

Insert screws into all jack screw holes indicated in the diagram for the Taper Lock Bushing for

your mulcher.

4.

Loosen the bushing by alternately tightening the screws in small but equal increments until the

taper sprocket and bushing surfaces disengage.
