Disconnect hose from fluid section.

5. Disconnect and remove fluid

section from gearbox, including
Connecting Rod Assy. (See"Fluid
Pump Disconnect, page 10)

6. Remove four nuts (page 20, Item

23) on the engine side of (Item 18)
from screws (Item 24) which pass
through spacer tubes (Item 15). This
will allow removal of Gearbox &
Clutch Assembly from "Holder-
Manifold" (Item 18).

7. Pull the cog belt loose from the

engine shaft cog pulley and remove
the gearbox/clutch assembly from
the rest of the unit.

8. Place gearbox in vice by gripping

the flat part of the drive crank
allowing the clutch assembly to
face up. Use caution and not allow
gearbox to swing and damage
casting against vice.

9. Hold coupling screw, with 13/16"

wrench, then with 5/16" allen
wrench, screw differential screw
out of coupling screw and gearbox
shaft.

10.Screw large end of differential

screw into coupling nut assembly
and pull out of clutch assembly.

11.The clutch can now be removed

Spacers, removable spacer,
replacement clutch, bearings,
retaining rings should be inspected
and replaced if needed. (Items 3
through 8 on Parts List).

Install new clutch as follows:

1. With gearbox held as described in

Step 8 above, place first spacer and
bearing onto gearbox shaft.

2. Insert snap rings (2 into recesses of

cog pulley portion of clutch. Place
cog pulley portion of clutch with
cog belt attached onto shaft.

3. Place second spacer into cog pulley

portion of clutch. This spacer will
rest on the first bearing installed.

4. Insert second bearing on top of

upper snap ring.

5. Lay removable spacer on top of last

bearing. If the clutch air gap is
larger than .028", do not use
removable spacer. Put spacer over
removable spacer, if used, and top
bearing.

6. Place coil portion of clutch down

onto cog pulley portion of clutch
and center on gearbox shaft.

7. Screw differential screw into

coupling screw and nut until 1/16"
is showing.

8. Push coupling nut assembly into

clutch assembly until it comes to a
positive stop. (Differential screw
comes into contact with the
threaded gearbox shaft.)

9. With 13/16" wrench on coupling

screw and 5/16" allen wrench in
differential screw, simultaneously
with both wrenches screw coupling
nut assembly into gearbox shaft by
turning clockwise until a positive
stop is reached.

10. Hold coupling nut assembly and

tighten diffential screw to 30 ft.-lbs.
This will expand the coupling
assembly, thereby holding the
clutch assembly to gearbox shaft.
Turn clutch observing clutch gap.
The pulley should turn freely with
a gap of .012 to .024" between the
two clutch faces. If the gap is
greater than .028, remove the
spacer. Reassemble and check gap
for proper clearance.

11. Place cog belt over cog pulley

portion of clutch. Loosen set screws
until set screws are approximately
1/4" above block tensioner.

12. Reassemble the spacers onto

screws. Simultaneously lift gearbox
assembly with clutch into position
by placing cog belt over engine
shaft log pulley and inserting the
four screws into Holder-Manifold
and replacing nuts (4). Tighten nuts
to hold assembly in place.

13. Slightly loosen screws (4).

14. Evenly tighten Set Screws until

flush with tip of block tensioner..
Check tension on cog belt by
pressing hard with thumb. Proper
tensioning should allow for
approximately 1/8". If belt is too
loose, tighten set screws further.

15. Replace connecting rod and fluid

section. Preplace front cover on
gearbox. Connect hose to fluid
section.

16. Connect the clutch and board leads.

Connect spring to spacer tube.

17. Replace the splash shield.

18. Test the clutch for proper operation

19. Replace clutch covers.

Maintenance

REGULAR MAINTENANCE

1. Always stop the pump at the

bottom of its stroke when you take
a break or at the end of the day.
This helps keep material from
drying on the rod and damaging
the packings.

2. Keep the displacement pump
