Front Plate, Backplate
and Adapter Plates Inspection
1. Oil groove in bushings in front plate, backplate and
adapter plates should be in line with dowel pin holes and
180 degrees apart. This positions the oil grooves closest
to respective dowel pin holes.
2. Replace the backplate, front plate or adapter plates
if l.D. of bushings exceed .879in. [22,33mm] (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. [,038mm].
Body Inspection
1. Check bodies inside gear pockets for excessive scor-
ing or wear.
2. Replace bodies if l.D. of gear 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.
Reassembly
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 (8), adapter
plates (20, 21), and backplate (30) with a small amount
of petroleum jelly to hold in place.
3. Tuck backup gasket (6) in front plate (8) and adapter
plates (20, 21) with open part of "V" section down.
4. Place balance pressure seal (5) in groove in front
plate (8) and adapter plates (20, 21).
5. Place plug (7) into pocket of front plate (8).
6. Apply a thin coat of petroleum jelly to both milled gear
pockets of front body (2). Slip body onto front plate (8)
with half moon port cavities in body facing away from
front plate.
