3.1.2. Select correct size breaking tip (fig.2.3) for the chain to be worked on and insert into alignment
bolt (fig.2.1) by removing push (extractor) bolt (fig.2.4), insert breaking tip (fig.2.3), with spring
(fig.2.2) under head of breaker pin, and replace push (extractor) bolt (fig.2.4). If small 2.2 mm tip is
used you must also use the upper and lower guides (see fig.3) to prevent breaking the tip.
The upper guide threads onto the alignment bolt, the lower guide drops in place in bottom of tool
body. Smallest pin (2.2 mm) should be used on most cam chains, 2.9mm pin on #25 or #35
chain and 3.8 mm pin for most motorcycle drive chains (428 to 530).
3.1.3. Put tool over chain, breaker pin tip must be withdrawn at least 2 mm into alignment bolt. The end
of the chain rivet should be held in position by the tool alignment bolt, the other end of the rivet
should be held in the tool body. Tighten the alignment bolt securely against chain to hold chain in
place.
3.1.4. Tighten push (extractor) bolt with a 14 mm wrench or lever bar until the chain pin is pushed
completely out, the chain pin will drop out of the hole in the bottom of the tool. Withdraw push
bolt and breaking tip, loosen alignment bolt and remove.
NOTE: When tightening push (extractor) bolt against chain link pin; if you don't feel the tip pushing down
smoothly, check that the tip is correctly lined up against the link pin. If not redo step 3.1.3 or you may break the
breaking tip.
3.2.
INSTALLING CHAIN LINK PIN (Riveting).
3.2.1. The rivet tip and anvil must be in place in tool.
3.2.2. Assemble the chain with the link to be rivetted. Special rivet link pins must be used, using original
pushed out pin is not recommended as the ends will be weakened. Do not use a split pin type
connecting link. The pin must be pushed all the way through the chain link, if the pin is hard to insert
it can be pushed into place by placing chain into the tool with the rivet tip withdrawn 2mm into the
alignment bolt and tightening the alignment bolt until the pin has been pushed through the link,
ensure that an equal length of pin shows on each side of the link.
3.2.3. Position the tool over the pin to be rivetted, make sure rivet tip is withdrawn 2mm into the
alignment bolt and tighten the alignment bolt securely against chain. Tighten the push (extractor)
bolt so that the rivet tip flares the chain pin. Both ends of the chain link pin should be flared so the
pin is securely held in place. Repeat procedure on other link pin.
3.2.4. Withdraw the tool, remove the chain; visually check that both chain link pins show the same flared ends.
NOTE: You may also use the press plates to flare the ends of pins as shown below (fig.4); use the press
plate with the two holes in in the upper jaw and the grooved press plate in the lower jaw. You may also use a
combination of the rivet pin and lower press plate as fig.5.
