Describe the work to be performed
Disassembly of the Drive Cone Unit
1. Using a 15/16" socket, remove the top nut from
the drive cones assembly. If air tools are not available,
the bottom of the shaft can be held in place using a 15/16"
open end wrench. (This allows the drive pulley to remain
attached to the shaft.)
NOTE: If the bottom nut releases first, reverse the shaft during
reassembly, as both ends of the shaft are identical.
NOTE: The cone shaft should slide out of lower cone, bearing and
cone frame, however, tapping the shaft through the upper cone
may be necessary if the cone has seized to the shaft. If
the cones cannot be removed by use of penetrating oil and
tapping the shaft, it will be necessary to cut the shaft in
order to remove and replace it.
2. Remove the upper and lower bearings from the cone frame.
NOTE: If the bearings do not slip out easily, they may be removed by use of a bearing driver or hammer and punch.
3. Inspect the bearings for wear. Inspect the spacers for burrs, wear or cracks.
Note: The bearings are identical and may be reversed without harm.
4. Inspect the drive cones for uneven wear, rough
spots, glazing or any other signs of wear or damage. See
the troubleshooting guide for examples of normal and abnormal
5. Inspect the keys, key ways and shaft for burring
or signs of wear or damage.
6. Replace worn, damaged or defective parts as
Re-Assembly of the Drive Cone Unit
1. Insert/press both upper and lower bearings into
NOTE: The bearings may require a press fit into the frame.
This can be accomplished with a press, hammer and drift or the
use of chilled bearings into a warm frame. Do not use any
2. Coat the cone shaft with Loctite Anti-Seize
NOTE: Ensure that the anti-seize is sprayed on the shaft only. Anti-seize will (ruin/destroy/etc) the drive cones and discups if it is sprayed onto the drive surfaces or any part that comes into contact with the drive surfaces.
3. Install the drive pulley and short key (PN 5070 superceded to 539115950) onto the cone shaft.
4. Reassemble the drive cone assembly by sliding the small black spacer onto the shaft and then inserting the shaft through the lower bearing in the bottom of the cone frame.
5. Slide the middle sized, zinc coated spacer onto the cone shaft.
6. Slide the lower drive cone, tapered end down, on the cone shaft. Align the key ways and insert the key.
7. Slide the large zinc coated spacer onto the cone shaft.
8. Install the upper cone and key.
9. While holding the bottom nut with a 15/16" wrench, tighten the top nut to a torque valve of 75 ft/lbs.
