Torque Hub Timing

    W1 series torque hubs must be timed prior to returning to service otherwise the unit will sustain severe damage when power is applied.  Proper timing of the unit is accomplished by placing the unit on a suitable work space with the planetary gears arranged, large cluster gear end up, at 2, 6 and 10 o'clock as shown in the diagram at right.   Each planetary cluster gear has a punch mark in the upper face of the gear.   Each of these marks must be turned to the 12 o'clock position.  When properly positioned the lower gear mark will show through the center hole (see diagram) and the upper two gear marks are just behind the carrier housing.

    By carefully placing the ring gear around the planetary assembly the gears can be held in the proper relationship while the assembly is installed into the hub.   The lower planetaries must mesh with the inner gear and the input gear should mesh with the upper planetaries in a B drive or the lower planetaries in an A drive.  It may take some adjustments to get all gears to mesh, but maintain contact between the ring gear and the upper planetaries in order not to loss the proper timing.  With all gears in place, temporarily place a shoulder bolt through the ring gear hole marked with an X and into a shoulder bolt hole in the hub casing.  The hub can now be roll tested to check for binding.  If hub does not rotate freely then check timing again.
