19. Install bearing spool into spring with #16421 tool.

Tighten a nut on the threaded rod of the tool against
the cover of the spring box to pull the tapered pin into
the spring.  Once the spring is spread, the spool can
be inserted behind the tapered pin and the tool can
be removed. 

20. Hook cable end to spring (#28) and route cable

around activating cam (#18).

21. Install spring box side covers (#26) and secure in

place with hardware.

22. Mount spring box onto handle using center mount

point only.  Align rear mounting holes but do not
install bolts.  Tighten center mount bolts.

23. To engage cable pin in activating cam slot it will be

necessary to apply tension to the threaded portion of
the cable.  This can be done by tightening a nut
against a spacer, such as a deepwell socket, on the
threaded end.  While applying tension, rotate the
lever arm backwards until you feel the cable pin snap
into its slot.  Once in place you will have constant
tension on the lever arm.  Rotate the lever arm
forward and release the trigger to lock the lever.

24. Install the remaining 4 bolts (#32).

25. Tighten the handle pivot bolt (#41).

26. Install handle on trowel.

Standard Handle Pitch Cable Replacement

Refer to Handle Assembly, page 22.

1.

Remove handle assembly from trowel.

2.

Remove switch assembly (#11).  It is not necessary
to disconnect the wire.

3.

Turn pitch control knob all the way counterclockwise.

4.

Spiral pin (#27) should be aligned with hole on left
and slot on right.

5.

Drive pin out toward the slot just far enough to
unhook cable.

6.

Slide clevis (#5) out of the tube and remove cable.

7.

Since it is not possible to thread the cable while the
clevis is in the tube, it must be put through the pulley
with the clevis removed.

8.

Route both ends of the cable into the bottom of the
tube.  The threaded end must come out of the slot.

9.

Insert clevis with cable into tube.  Use a handle bolt
to hold clevis in place.

10. Push cable up align eyelet with spiral pin hole.

11. Press spiral pin in flush with outside of slot on handle.

12. Install switch on handle.

13. Install handle on trowel.

Spider Bushing Removal

Refer to Figure #8

1.

Screw a 3/4-14 pipe tap about half way into the worn
outer bushing.

2.

Insert a 3/4” x 8 1/2” push rod into the opposite side
of the spider.

3.

Use a 1 1/4” x 4” tube on upper end to press old
bushings out.

4.

Repeat with inner bushings.
