4. Locate and remove master link (item 16) from drive
chain. Note direction of master link clip for assembly pur-
poses. Remove drive chain.
CAUTION
Before disconnecting any hydraulic compo-
nents, operate all hydraulic controls to relieve
system pressure and avoid injury from pressur-
ized hydraulic oil. See Relieving Hydraulic Sys-
tem Pressure in the General Information section
of this chapter.
5. Relieve hydraulic system pressure.
6. Clean floor motor and all hydraulic connections at
motor. Label hydraulic lines for assembly purposes.
7. Disconnect hydraulic hoses from hydraulic fittings on
floor motor. Allow hydraulic oil to drain from lines into a
suitable container. Put caps or plugs on open hydraulic
lines and fittings to prevent contamination.
8. Remove cap screw (item 11) and flat washer (item
12) that secure sprocket (item 4) to floor motor shaft.
9. Loosen two (2) set screws (item 15) that secure
sprocket to floor motor shaft. Slide sprocket from shaft.
Locate and retrieve woodruff key (item 17) from motor
shaft.
10.Support floor motor to prevent it from falling.
11. Remove two (2) cap screws (item 9) and lock nuts
(item 10) that secure floor motor to frame. Remove floor
motor from machine.
12.If hydraulic fittings are to be removed from floor mo-
tor, mark fitting orientation to allow correct assembly.
Remove fittings from motor and discard O--rings.
Installation (Fig. 39)
1. If fittings were removed from floor motor, lubricate
and place new O--rings onto fittings. Install fittings into
port openings using marks made during the removal
process to properly orientate fittings. Tighten fittings
(see Hydraulic Fitting Installation in the General Infor-
mation section of this chapter).
2. Position floor motor to frame and secure with two (2)
cap screws (item 9) and lock nut (item 10).
3. Apply antiseize lubricant to floor motor shaft.

4. Position woodruff key to slot in floor motor shaft and
then slide sprocket (item 4) onto shaft.
5. Install cap screw (item 11) and flat washer (item 12)
into end of floor motor shaft.
6. Slide sprocket to end of motor shaft so that it contacts
flat washer.
7. Apply Loctite #242 (or equivalent) to threads of set
screws (item 15). Install and tighten set screws to secure
sprocket to motor shaft.
8. Remove all caps or plugs that were placed on hy-
draulic hoses and fittings during disassembly.
9. Using labels placed during motor removal, correctly
install and tighten hydraulic hoses to hydraulic fittings on
floor motor (see Hydraulic Hose and Tube Installation in
the General Information section of this chapter).
10.Fit drive chain onto floor motor, drive roller shaft and
idler sprockets. Install master link (item 16) to drive
chain and secure ends with master link clip. Make sure
that the closed end of the master link clip is facing the
direction of chain rotation.
NOTE: Direction of normal roller rotation is shown in
Figure 40 as viewed from right side of conveyor.
11. Check that chain is aligned to sprockets. If alignment
adjustment is necessary, move sprocket on roller drive
shaft as needed.
12.Move idler sprocket to tension the drive chain. Se-
cure idler sprocket by tightening cap screw and lock nut.
A properly adjusted chain should allow for free rotation
of drive components.
13.Secure guards to frame (see Bed Guards in the Ser-
vice and Repairs section of Chapter 5 -- Chassis).
