* Special BW1620XQREV units use a 1029694REV gearbox instead of the standard gearbox on the center section (Model
1620XQREV only). This changes rotation from counter-clockwise to clockwise.
** Input gear (32) with input shaft spacer (29) is placed on opposite end of input shaft from bearing spacer (24)
Instructions for reversing gearbox 1029694 for use on center section of BW1620XQREV:
1. Disassemble gearbox cross-shaft.
2. Move gear (32) to opposite side of box.
3. Reassemble and shim gear to get a backlash of .006 to .016 at pinion.
