INSTALLATION INSTRUCTIONS
To assemble:
1. Clean and degrease the bore and taper
surfaces of the bushing and the taper bore of the
wheel. Insert the bush into the hub and the wheel
to line up holes (half thread holes must be lined
up with half unloading holes)
2. Lightly oil the grub screws (bushing size 1008
to 3030) or the cap screws (bushing size up to
5050) and screw them the holes. Do not tighten
yet.
3. Clean and degrease the shaft. Fit the wheel
with taper bushing onto the shaft and locate it in
desired position.
4. When using a key, it should be fitted first in the
shaft keyway. There should be a tap clearance
between the key and the keyway in the bore.
5. Using a hexagon socket wrench (DIN911)
gradually tighten the grub/cap screws in
accordance to the torques as listed in the table of
screw tightening torques on the left.
6. When the drive has been operating under load
for a short period (half to one hour), check to
make sure that the screws remain at the
appropriate tightening torque.
7. Fill all empty holes with grease in order to
eliminate the entry of dirt.
To remove:
1. Loosen and remove all screws and place them
in the holes of the bushing.
2. Tighten the screws alternatively until the hubs
grip on the bushing is loosened. The inner bore of
the bushing can be slid off the shaft.
3. Remove the bushing from the shaft.
Special Note:
BTL bushings are manufactured in GG25 cast iron.
Other materials are available upon request.
Surface coatings such as painting, black phosphating
or black oxidizing are optional.
