Removing and Replacing the Clincher Points (Figure 20)

The Clincher Point (7024B or 7257B), when worn,

may cause poorly formed staple legs. Loosen, but do

not remove, the two (2) Round Head Machine

Screws (UA3310.3) until the Clincher Slide (18182)

can be disengaged from the stitcher machine and slid

out of the Clincher Plate Assembly (7253A or

7650A) or down within it. Rotate the Clincher

Points upwards until they could be pulled out.

Replace the Points when they are worn or chipped.

Rotate the Clincher Points downward before

replacing the Clincher Slide. Make sure the Points

are engaged by the Slide before tightening the

Machine Screws in the Clincher Slide Retaining

Strap (7256B).

Disassembling the Stitcher Head (Figure 21)

Remove the G20 style Stitcher Head from the

stitcher machine. On Clamp-mount style heads,

loosen the two (2) Clamp Block Eccentrics (G20524 or G20503 and G20524) and remove the Stitcher

Head from the Bonnet Clamp Blocks (G20501 or G20502). On Bolt-mount style heads, loosen and

remove the Bonnet Stud Nut (HN1213) while supporting the Head. Remove the Head from the

stitcher machine and place it on a clean work area.

Swing the Wire Holder Retaining Spring (G20583) away from the G20 and remove the Wire Holder

Assembly (G20559BA). Snap the Middle Wire Tube (G20544A) out of the Middle Wire Tube Clip

(G20244) and remove it from the Lower Wire Tube (G205199A) in the Cutter Block Assembly

(G20597BA). Remove the two (2) Cap Screws (G20596) and the one (1) Cap Screw (G20589)

securing the Feed Gear Bracket (G20536) to the Bonnet Assembly (G20500A) and remove the Feed

Gear Bracket. Remove the two (2) Socket Flat Head Screws (G20616) securing the Cutter Block

Assembly to the Bonnet and remove the Cutter Block. Remove each of the Cap Screws (G20589 and

G20596) to release the Wire Holder Pivot Block (G20543 or G20643) from the Bonnet. Remove the

Cap Screw (G20697) from the Adjustment Block (G20592) and Upper Adjustment Slide (G20645).

The Adjustment Block, Feed Slide (G20531), Bender Slide (G20562) and Bender Bar (G20547) can

be removed from the top of the Stitcher Head now. Be careful when removing the Bender Slide and

Bender Bar and there is substantial pressure between the Plungers and Springs.

Remove the Feed Lever Spring Bushing (G20267) and Feed Lever Spring (G20668) from the Feed

Lever Extension (G20534B). Loosen, but do not remove, the Screw (G20681) securing the Feed

Lever Pin (G20262A) in the Bonnet Assembly and remove the Feed Lever. Check the Feed Gear

Shaft Plate (G20582) for wear or warping and replace if necessary.
