CLUTCH AND BRAKE

1.

You now have access to the clutch (37)
and the drive gear assembly (39). 
Normally, the drive gear will remain in
the motor mount and can be removed by
pulling it straight out.  The clutch will be
loose in the gear housing as the spring
behind the clutch forces it outward.

2.

With these parts removed, wipe out all
the surrounding grease to remove any
metal chips that may be present.  The
idler gear (27) and the eccentric shaft
(26) have been previously removed to
facilitate cleaning and allow repacking of
the needle bearings (29, 80) in the gear
housing and motor mount prior to
reassembly.  Check idler gear pin (30) for
wear.  This portion of the tool is to be
repacked about 50% full with Non-fluid
Oil No. K-55 (Signode Part No. 177029).

3.

Check the teeth of the clutch (37) and the
drive gear assembly (39A) for wear. 
Replace if necessary.  Also, check the
needle bearing (38) in the center of the
drive gear for wear and make certain the
needles turn freely. 

4.

With a moderate amount of grease
added, a new clutch can be installed on
the spline of the Spiroid worm (28) and a
new drive gear assembly (39A) can be
installed into the motor mount. 

5.

Remove spacer sleeve subassembly (32,
33, 34, and 35).  Disassemble by 
grinding or filing the two stakes, if
necessary.  Replace the brake (34). 
Make certain that the flat surface of the
brake is facing the brake springs (33)
and insert the springs with the concave
side towards the washer (32).  Stake the
spacer sleeve twice and replace the
spacer sleeve subassembly. 

6.

Assemble the clutch spring (36) and the
clutch (37) on the spline of the Spiroid
worm and press down to weld position. 
Remove the weld handle subassembly
from the weld housing and insert it into
the gear housing in the sealing position. 
The  cam on the pressure eccentric will
be engaged with the groove of the
clutch. This will hold the clutch
assembly in place when reassembling
the tool.

7.

Add lubricant to the drive gear assembly
(39A) and insert it into the motor mount
(41). Also add lubricant to the idler gear
(27) and the eccentric shaft (26) then
insert them into the tool.  Reassemble
the motor mount to the gear housing
and secure it with the three socket head
cap screws.

8.

Refer to the illustration on page 27.
Examine the small dowel pin (50) that
sits in the groove in the contact stem
(44), for wear. Replace if necessary.
Liberally lubricate with MO-Lith No. 2.
This will also hold the pin in place
during reassembly. Remove the weld
handle from the tool and reassemble it
into the weld mechanism with the
following components.  Inspect and
replace the parts as needed and add
lubricant:

!

  Pressure eccentric (66)

!

  Lift tab (49) 

!

  Compression plate (43)

!

  Die spring (45)

!

  Shim (81)

!

  Contact stem (44)

!

  Dowel pin (50)

!

  Weld housing (24)

Examine the bushings (64 and 65) in the
weld housing (24) for wear and replace
as required.

9.

Check the valve components for cut
tubing or loose fittings, reassemble all
parts, being careful not to crimp or pinch
the tubing, and operationally test the
tool.
