6.0 6” J-FORCE MAINTENANCEWhen not in use, the 6” J-Force should
be cleaned to remove any debris, deposits, or contaminants that could
impede rotation, and sprayed with water-dispersing lubricant (e.g. WD-
40) for storage until next use.
The 6” J-Force utilizes water-bearing technology coupled with an eddy-
current braking system to control the rotation speed. No oil is required,
allowing for a quick and pain-free rebuild of the tool.
See YouTube for videos showing 6” J-Force service.
The use of gloves is recommended when handling the tool
after operation as the body may reach temperatures greater than 200’F.
6.1 DISASSEMBLY FOR MAINTENANCE
1. While holding the inlet nut (2) stationary in a vice or with a 1-1/4”
wrench, unscrew the mandel (6a) by turning it counterclockwise
with a 1/2” socket wrench.
2. Once the mandrel is unthreaded from the inlet nut, the inlet nut and
adjuster (1) will separate from the head assembly (5) as one piece.
Once the magnets in the back of the head assembly are exposed,
take care to protect them from mechanical damage. The magnets
are fragile and will crack upon any significant impact.
3. Remove the mandrel (6a) and thrust bearing (6c) from the head
assembly (5).
4. Remove the flange bushing (6b) from the head assembly (5) by
pushing it out from the back side. The bushing removal tool (PN
66967) may be used to make contact with the back edge of the
flange bushing to push it out, as shown below. Note orientation of
tool.
