Front Plate, Backplate
and Adapter Plates Inspection
1. Oil groove in bushings in front plate, backplate and
adapterplates should be in line with dowel pin holes and
180degreesapart.Thispositions theoilgroovesclosest
to respective dowel pin holes.
2. Replace the backplate, front plate or adapter plates
if l.D. of bushings exceed .879in. (22.33mm).
Note: Bushings are not available as separate items.
3. Bushings in front plate and backup gasket side of
adapter plates should be flush with face of plate.
4. Check for scoring on face of backplate or adapter
plates. Replace if wear exceeds .0015 in. (0.038mm).
Body Inspection
1. Check bodies insidegear pockets for excessive scor-
ing or wear.
2. Replace bodies ifl.D. ofgear pockets exceeds 2.1 in.
(53.54mm).
General Information
It is important that the relationship of the backplate,
adapter plates, bodies, wear plate and front plate is cor-
rect. You note two half moon cavities in the body which
must face away from the front plate or adapter plate.
Note: The smaller half moon port cavity must be on the
pressure side of the pump. The side of wear plate with
mid section cut out must be on suction side of pump.
Suction side of backplate or adapter plate is always the
side with larger port boss.
Assembly (Fig. 35)
1. Replace the wear plates, bearing seals, backup gas-
kets, shaft seal and o-rings as new parts.
2. Install O-rings (1) in groove of front plate, adapter
plates, and backplate with a small amount of petroleum
jelly to hold in place.
3. Tuck backup gaskets (6) in front plate and adapter
plates with open part of “V” section down.
4. Place balance pressure seals (5) in groove in front
plate and adapter plates.
5. Place plug (7) into pocket of front plate.
6. Apply athin coat of petroleum jelly to both milled gear
pockets of front body (2). Slip body onto front plate with
half moon port cavities in body facing away from front
plate.
Note: The small half moon port cavity must be on the
pressure side of pump.
7. Place wear plate (4) on top of backup gasket (6) with
bronze face up. The side with the mid section cut away
must be on suction side of pump.
8. Dip drive gear assembly (3) and idler gear assembly
(13) into clean oil. Slip both gear assemblies into gear
pocket of front body and into front plate bushings.
9. Place wear plate (4) on top of backup gasket (6) with
bronze face up. The side with the mid section cut away
must be on suction side of pump.
10. Install front adapter plate in place on front body.
Check positioning marks.
11. Install middle body onto front adapter plate and
install wear plate (4).
12. Install key (14) in slot of drive gear shaft (3). Dip slip
fit gear (15) in clean oil and slip on shaft and into gear
pocket of middle body. Check key for proper alignment.
13. Dip idler gear (18) in clean oil and install in gear
pocket of middle body.
14. Install rear adapter plate in place on middle body.
Check positioning mark on all sections of pump.
15. Install rear body onto adapter plate and install wear
plate (4).
16. Install key (19) in slot of drive gear shaft assembly.
Dip slip fit gear (17) in clean oil and slip on shaftand into
gear pocket of rear body. Check key for proper location.
17. Dip rear idler gear (24) in clean oil and install in gear
pocket of rear body.
18. Position backplate over shafts until dowel pins in
body are engaged.
19. Secure with cap screws (10). Tighten cap screws
evenly in a crisscross pattern to 25 to 28 ft-lbs. (34 to
38 Nm).
20. Place washer (12) overdrive shaft into housing.Lib-
erally oil shaft seal (11) with clean oil and install over
drive shaft c arefully so that rubber sealing lips are not
cut.
21. Place 1-3/8” O.D. sleeve over shaft and press in
shaft seal (11) .200 in. (5.08 mm) below front surface of
front plate.
22. Install key on keyed shaft.
