13. Slide gearbox set collar (2-3/8") up drive shaft until flush with gearbox. Tighten set screw.
Use 5/16" x 3/4" whiz lock bolts and nuts.
14. Fill gearbox lubricant reservoir with lubricant. (See Figure 22Z and Figure 22AA on Page 237.)
Gearbox lubrication: Gearbox requires amoco perma gear 220 (or equivalent lubricant). Remove
gearbox lubricant reservoir plug and fill reservoir 1" to 1-1/2" from top. Remove fill hose.
NOTE: This is a slow process.
IMPORTANT: It is very important that no air is left in reservoir. Remove fitting from top of gearbox.
Add a few more ounces of lubricant to gearbox lubricant reservoir, until lubricant
reaches fitting hole.
Replace plug and check for leaks.
