Hub Lubrication
The wheel bearings should be checked for wear and/or damage annually (Figure 37) . Repack with grease before first use of
the season . Use an EP2 grease . The inside of the hub is filled about 75% with grease to allow for heat expansion .
After the wheel bearings have be greased and placed back on the spindle, grease the washer and place on the spindle, then
thread the castle nut . Tighten the nut using a wrench and rotate the hub in the opposite direction . The wrench should not drag
against the hub when tightening . Tighten until the hub doesn’t rotate freely using one hand . Back the nut off 1/2 turn, retighten
the nut to the next slot and insert the locking pin (either a roll pin or a split cotter pin) . The hub should rotate with one hand and,
depending on the speed of rotation, the radial momentum will keep the hub rotating for a partial (1/8 to 1/4) turn after letting
go of it . This should provide for the desired preload . If using a split cotter pin, bend the ends to secure the pin, then replace
the hub cap gasket and hub cap .
Recheck the preload after 5 to 10 hours of use .
Hitch Lubrication
The Bull Pull hitch has two (2) grease fittings, one on each side (Figure 38) . These should be greased daily under normal
conditions .
