Gear Box Final Assembly

1. Bearing drag is adjusted by the amount of gaskets

(It

em 4, 5, 6) used between the cap and housing ma-

chined surfaces.

2. Put two 0.015 in. gaskets on the machined surface of

the

housing, then install the shaft and cap assembly in

the housing so the bearing cone (Item 9) on the shaft

assembly and bearing cup (Item 3) in the housing are

mating. Align the holes in the cap with the holes in the

gaskets and housing.

3. Install capscrews and tighten.

4. The shaft should have a very slight amount of bearing

rag. If the shaft turns hard, the cap must be removed

and gasket(s) need to be added. If the shaft has no

bearing drag, or has end play, the cap must be removed

and gasket(s) taken out. The cap must be adjusted to

where the shaft has no end play and only a slight amount

of bearing drag.

5. Repeat steps 1 - 4 with the other shaft and cap

asse

mbly.

6. After installing the gear box on the cutting unit, fill it

with SAE 80W90 API GL-5 lubricant to the level of the

check plug (see Maintenance section in this chapter).
