Gears - Ball Winder
The ball winder contains 4 gears: 2 Spur and 2 Bevel gears. These multiply the RPMs from the motor or by hand cranking, by 5X.
The gears can be broken if the owner does not keep the system clean of fiber debris and other gunk. Foreign material will jam the gear crevices and then in order to turn it the user must apply excessive force to turn the handle and that is where the trouble comes in.
The Bevel gear must be changed out by NKK since it pinned onto a 10mm shaft. Both the Cluster and the Torque Tube Gears can be changed out by the user.
Torque Tube Assy's that were used in or around 2009-2013 and which have a black bushing in the top of the assy. "may" experience an issue with expansion of the black bushing material. This material (molybdenum) was a space age material but ended up absorbing moisture which could cause the bushing to tighten around the shaft. This would occur as the unit aged over years. The solution was easy, bore the hole out to a greater inside diameter. The new ID is 0.380" and users can bore theirs out, if necessary, provided they use a .380" reamer bit. Otherwise, we can do it for the user for free if the torque tube is returned to us.
If you need a torque tube to use while yours is being repaired, then order one here and we will refund your purchase (less shipping) when we receive our unit back. Please return it within 30 days.
Please note that only some of the units made during this time experienced this problem.
The way to test whether or not the torque tube is causing your problem is to remove the spindle arm and the collar that holds the torque tube in place. Then remove the torque tube, turn it upside down with the black bushing facing downward and placing it back on the shaft. See if it gets hung up and does not slide down the shaft easily (once you get past the small indentations caused by the set screw). If after clearing the set screw marks it does not slide down easily, then your torque tube may have this issue. However, also clean the shaft of oils and crud as well as the inside of the torque tube (let the tube sit in a vessel of rubbing alcohol to loosen the dirt that may have accumulated there).
