Section 3 Back End Gearbox
3.1 Purpose
The purpose for this section is to provide a description of the XLi back end gearbox as well as to provide
maintenance and repair procedures for the gearbox.
3.2 Scope
This section provides an operating overview of the back end gearbox as well as procedures for the initial
setup and subsequent maintenance and repair of the XLi pinspotter back end gearbox.
The back end gearbox is a speed reducing, single input, triple output gearbox that is available in two
different gear ratios: one for 50-hertz motors and another for 60-hertz motors, as well as right hand (odd)
and left hand (even) versions for each gear ratio for a total of 4 different models. The gearbox’s three
output shafts turn at different speeds to operate the Distributor, the Pin Lift, and the Pit Conveyor Belt, Light
Ball Sensor, and Positive Ball Lift.
The procedures for all back end gearboxes are identical, although the two gear ratios have unique worm
assemblies. The 50-hertz and 60-hertz gearboxes can be identified by the frequency rating located on the
nameplate attached to the gearbox. As a visual indicator, nameplates with black printing are associated with
60-hertz gearboxes, and nameplates with red printing signify 50-hertz gearboxes.
