SERVICING / CHANGING FEEDWHEEL BEARING
(WITH THE GRIP TIGHT BEARING BEHIND FEEDWHEEL MOTOR)
Grip Tight Bearing
Set Screw Bearing
MAINTENANCE
Your Bandit Chipper may be equipped with a tapered lock style (Grip Tight) feedwheel bearing on the
hydraulic motor side of the feedwheel and a conventional (set screw) style on the opposite side. With the
Grip Tight bearing this gives a very positive locking system to the feedwheel shaft. The set screws on both
bearings should still be checked as part of normal maintenance.
A few simple rules and installation instructions must be followed if the bearings ever need to be replaced
or removed during service.
The machine is set up with one set screw bearing and one Grip Tight bearing because the one Grip Tight
bearing is all that is needed to securely hold the feedwheel shaft (along with the set screws on the opposite
bearing). This also makes for very easy assembly.
When installing the bearing it is very important to
install and lock the Grip Tight bearing fi rst with the set screw bearing done after.
This is to keep the
bearings from being put into a side load which will lead to premature failure.
Installation procedure:
1. Clean the feedwheel shaft of all debris, use a degreaser.
2. Install both feedwheel bearings on the feedwheel shaft with the Grip Tight bearing on the hydraulic motor
side and the set screw bearing on the opposite side.
Do not lock the bearing on the shaft at this time,
allow the feedwheel to shift freely for installation.
3. Position the feedwheel in the yoke mount and install all (8) feedwheel bearing bolts with Loc-Tite 263 (red)
applied. These are completely tightened and torqued at this time (refer to bolt torque chart).
4.
The feedwheel then needs to be centered in the yoke and then it must be off set 3/16” (4.8 mm) towards
the set screw bearing side (away from the hydraulic motor). The weight of the feedwheel needs to be
taken off the bearing also.
5. First the Grip Tight bearing lock must be tightened by hand as tight as possible (in a clock wise direction).
This is the zero reference point. Scribe a line on the lock nut above the adapter slot.
6. Using a spanner wrench or drift pin and hammer, lock the bearing to the shaft by tightening the lock nut
in a clock wise direction. Tighten 3/4 to 1 full turn (you may need to block the feedwheel from turning at
this time). Now you can tighten the set screws on the Grip Tight bearing. Note: the set screw is only to
be tightened to 25 in.-lbs. (2 ft.-lbs.) (2.7 Nm).
7. Apply Loctite 263 (red) on the set screws of the set screw bearing and torque to 20 ft.-lbs. (27 Nm).
