- 10 -

longer hub of the worm gear is down.  The worm gear
should be pressed on the shaft until the recess in the
worm gear hub is snug against the retaining ring.

3.

Press one bearing (#3) on each end of the shaft.
Make sure the bearings are butted against the worm
gear shoulders.

4.

If the bearing races are replaced make sure the new
races are properly seated.  

5.

Set the worm gear and the shaft assembly into the
gearbox housing and put cover (#8) and one .010”
shim #05401 (#11) into place.

6.

Apply down pressure to cover (#8) and check shaft
(#14) for end play.

7.

Remove the cover and install the proper shims (#11)
for no end play.

8.

Brush a light coat of oil on the o-ring groove and
inside the lip of the cover.  Roll the o-ring (#5) over the
inside lip and into the groove in the cover.  Install the
seal (#1) into the cover from the outside and make
sure it is installed square and flat.

9.

Use a piece of thin plastic over the shaft to protect the
seal and install the cover into the gearbox housing
and secure it with two flange bolts (#24) and two flat
head screws (#25). 

10. Rotate the shaft, there should be a little drag.  If there

is too much drag another shim should be added until
a slight seal drag is felt.  If there is side play in the
shaft a shim must be removed.

11. Measure the main shaft run out.  Maximum

acceptable total indicator run out is .0035 inches.

12. Install the drain plug (#26) and relief valve (#16) if

removed.  Use pipe sealant on the threads before
installation.

13. Brush a light coat of oil on the o-ring (#17).  Roll it

over the inside lip and into the groove of the retaining
cap (#21).

14. Install two .010” shims #05360 (#10) with the

retaining cap on the drain plug side of the gearbox
housing with four flange bolts (#23). Torque the bolts
to 90 in/lbs in an “X” pattern.

15. Press one bearing (#22) on each end of the worm

shaft (#19).  Make sure the bearings are butted
against the worm shaft steps.

16. Install the worm shaft (#19) with the bearings (#22)

into the gearbox housing.  The gears must be
meshed properly.

17. Install the bearing cap (#20) and apply pressure

towards gearbox (#7).  Rotate the worm shaft and
check for end play and gear backlash.

18. Remove the bearing cap and install the proper shims

(#10) for no back lash & no end play.

19. Remove cover and install the proper shims (#10) for

no back lash and end play.

20. Install a new seal (#18) into the bearing cap (#21)

from the outside.  Make sure the seal is installed
square and flat.

21. Brush a light coat of oil on the o-ring groove.  Roll the

o-ring (#17) over the inside lip and into the groove of
the bearing cap.

22. Pour one can (21 oz.) of #05700 oil into the worm

shaft bearing cap opening.  Install the cap and secure
it with four flange bolts (#23).  Torque the bolts to 90
in/lbs in an “X” pattern.

CFP Handle Cable/Spring Replacement

Refer to Constant Force Handle Assembly, page 24.

1.

Remove handle assembly from machine.

2.

Support handle assembly in a vise to secure for
disassembly.

3.

Loosen handle pivot bolt (#41) and fold handle
forward.

4.

Remove the four bolts (#32) on the back of the
springbox.

5.

Carefully rotate lever (#19) arm backwards until you
feel the cable tension release.  When it releases there
will be no spring tension on the lever (#19) in either
direction.

6.

Remove spring retainer bolt (#45) and end covers
(#26).

7.

Remove remaining two bolts (#33) to separate spring
box (#25) from handle.

8.

With a long needle nose pliers, disconnect the cable
from the spring.

9.

If you are only replacing spring (#28) proceed with
step 10.  If you are replacing cable and/or clevis refer
to step 13.

10. Note orientation of spring assembly.  Remove

bearing spool (# 29) by pushing it out either side.

11. Remove spring assembly by forcing it out either side.

12. Refer to step 18 for assembly.

13. Push threaded portion of cable into tube.

14. Slide clevis assembly out of tube toward the bottom.

15. Remove cable from tube.

16. Route barrel end of new cable into tube. 

17. Route threaded portion of the cable over the pulley on

clevis and back into the tube.  Guide the threaded
end through the slot in the handle as you insert clevis
into the handle tube.  Insert one of the handle bolts
through the clevis mounting holes to hold it in place.
See figure 7.

18. Install spring (#28) into spring box (#25). Note

bearing spool must be removed to get spring into
housing.
