(34) Install three new gaskets (24) and rear output

end plate (19) on housing (25) with four screws

(27).

NOTE

Bearings are adjusted by removing

gaskets until bearings bind, then

adding one gasket at a time until

shaft rotates freely with no end play.

Number of gaskets on each end

should not vary from other end by

more than one.

(35) Remove gaskets (24), one at a time, from front

output end plate (22) and rear output end plate

(19) until bearing cones (15 and 17) just bind

when turning output shaft (12) by hand.

(36) Add gaskets (24), one at a time, to front output

end plate (22) then rear output end plate (19)

until output shaft (12) rotates freely with no end

play.

NOTE

All

keyways

should

face

the

mounting side of Tee box when

properly assembled.

Gear teeth

should mesh as parts are assembled.

(37) Align keyways in output shaft (12) and pinion

shaft (6) and Install three new gaskets (24) and

pinion end plate (4) on housing (25) with four

screws (28).

(38) Move gaskets (24), one at a time, from front

output end plate (22) to rear output end plate

(19) until pinion shaft (6) and output shaft (12)

rotate freely with no backlash.

NOTE

To properly adjust backlash, two

gaskets must be moved from front

output end plate to rear output end

plate.

If there are not enough

gaskets at rear output end plate to

move to front output end plate,

further gear adjustment must be

made by removing two gaskets from

between pinion end plate and

housing and repeating steps (32)

through (38).

(39) Move two gaskets (24) from rear output end

plate (19) to front output end plate (22).
