IMPORTANT NOTE: The WD & WP Series Motors depend on the correct orientation of parts as well as correct internal timing
for proper motor operation. Before disassembling the motor, it is highly recommended that paint or a marker be used to make a
“V” shaped set of lines from the endcover to the housing. This will aid in reassembling the motor components properly. It is also
important that the steps involving internal parts timing be followed carefully to insure proper motor operation.
Remove all shaft related components from shaft (14) (i.e. keys, nuts). To aid in reassembly of the motor, make a “V” shaped set of
lines from the endcover (10) to the housing using either paint or a marker. With shaft facing down, secure motor in vise by clamp-
ing on to the housing (6).
Loosen and remove seven bolts (13) with washers (12) holding motor assembly together. Remove endcover (10). Remove rotor set
assembly (9), drive link spacer (16) & wear plate (8). NOTE: Some WD & WP models do not use a drive link spacer (16). Re-
move body seals (5) from rotor assembly (9) and housing (6) and discard seals. Remove drive link (7) and thrust bearing (4) from
motor and lay aside. NOTE: The WD does not use the thrust bearing between the shaft and wear plate.
Gently tap shaft (14) upward through housing (6) and remove through rear of housing. Remove housing (6) from vise. Collect
thrust bearing (4) and thrust washer (3) from the rear of the housing while turning the housing over and discard thrust washer (3).

At this point, all parts should be cleaned in an oil-based solvent and dried using compressed air (For safety, observe all OSHA
safety guidelines). All new seals should be lightly coated in clean oil prior to installation.

Install shaft seal (2) down onto shaft (14) making sure that lip on seal faces down. (See Figure 1 for shaft component orientation).
NOTE: To return the WD & WP Series Motors to proper operation, the rotation code of the motor must be known. The rotation

code is not known, and if port ‘A’ is pressurized , motors that are to have the shafts turning clockwise (as viewed from the shaft
end) should be timed using the “145” or “155” series and motors that are to have the shafts turning counterclockwise (as viewed
from shaft end) should be timed using the “146” or “156” series.
Turn shaft (14) over so that output end of the shaft faces down. Lower drive link (7) into shaft making sure that the timing mark end
of drive link faces up and that the timing mark on the end of the drive link (7) is aligned to the left of any short, open cutter slot on
shaft (14).
Turn housing (6) over so that the pilot of housing faces down and secure housing (6) in vise. Without disturbing the shaft seal (2),
and drive link (7), carefully lower shaft assembly into housing. Apply pressure using an arbor press or a rubber mallet to make
sure that the shaft end is slightly lower than the housing bolt hole surface to allow for the rear thrust bearing (4). For WD series

Place a body seal (5) in groove in the rear surface of the housing (6). Place thrust bearing (not used in WD series motors) in the
housing (6) on top of shaft (14). Place wear plate (8) on housing. Make sure that the seven valving slots on the wear plate line up
with the seven bolt holes on the housing (6).
Place a body seal (5) in the grooves on both sides of the rotor assembly (9). With the seal groove surface on the rotor assembly
facing wear plate, lower rotor assembly (9) onto drive link (7) making sure that the timing mark on drive link is aligned with a peak
on the rotor (9) for 146 or 156 series, or with a valley on the rotor (9) for 145 or 155 series (See Figure 2). After assembling the
rotor assembly on the drive link rotate the rotor assembly to line up the assembly bolt holes.
Place drive link spacer, (16) if used, inside rotor assembly on top of the drive link (7). Place endcover (10) onto motor. There is no

Remove motor from vise and place on work surface with shaft (14) facing up. Making sure that lip on dust seal (1) faces up, place
dust seal (1) over shaft (14). Using a sleeve and hammer, carefully drive dust seal (1) into place.
