Gearbox Final Assembly
1. Bearing drag for input shaft (Item 8) is adjusted by
am
ount of gaskets (Item 7) used between thru cap
(Item 14), and housing machined surfaces.
2. Put two 0.015 in. gaskets on machined surface of
ho
using, then install shaft and thru cap assembly in
housing so bearing cone (Item 4) on shaft assembly and
bearing cup (Item 3) in blank cap (Item 2) are mating.
Align holes in caps with holes in gaskets and housing.
3. Install capscrews and tighten.
4. shaft (Item 8) should have a very slight amount of
be
aring drag when turned. If shaft turns hard, cap must
be removed and gasket(s) need to be added. If shaft
has no bearing drag, or has end play, thru cap (Item 14)
must be removed and gasket(s) taken out. thru cap must
be adjusted to where shaft has no end play and only a
slight amount of bearing drag.
5. Gear lash is adjusted by amount of gaskets (Item 7)
u
sed between hub (Item 17), and housing machined
surfaces.
6. Put two 0.015 in. gaskets on machined surface of
ho
using, then install shaft and hub assembly in housing.
Align holes in hub with holes in gaskets and housing.
7. Install capscrews and tighten.
8. output shaft (Item 19) should turn freely with a slight
amount of bearing drag and no sticking or binding. If
shaft turns hard, hub (Item 17) must be removed and
gasket(s) need to be added. If shaft has free play
(backlash), cap must be removed and gasket(s) taken
out. hub must be adjusted to where shaft has minimal
backlash and only a slight amount of bearing drag.
assembly must turn freely without sticking or binding.
9. After installing gear box on cutting unit, fill it with SAE
80
W90 API GL-5 lubricant to level of check plug.
