RIVETING CHAIN PINS
Assemble the tool as shown in Image E for riveting hollow-nosed master link pins. Thread the alignment bolt
into the body. Insert the rivet tip into the spring and drop them into the alignment bolt with the spring under the
tip head. (Refer to internal diagram with Image B). Thread the push bolt into the alignment bolt above the tip.
Place the anvil in the hole in the tool body per Image G. (Small anvil used for up to 3-series cam chains only).

1-The new master link side plates should already be pressed (see Pressing Side Plates) so that the chain pin
protrudes past the face of the master link’s side plate. Refer to the chain manufacturer’s specifications for the
proper protrusion distance. Do not attempt to re-use broken master links, or use a clip on a rivet type master
link. Position the tool over the chain pin to be riveted, with the hollow end of the chain pin facing the rivet tip,
and the solid end facing the anvil.
2-Make sure the rivet tip is withdrawn enough to clear the end of the chain pin. Tighten the alignment bolt
securely against the side plate of the chain, but do not over-tighten.
3-Using the lever or a 14mm wrench, tighten the push bolt very tightly until the rivet tip spreads the hollow nose
of the chain pin. The end of the chain pin should be flared over the side plate just enough so that the side plate
is solidly held in place. Repeat this procedure on the other chain pin. The amount of flare of a rivet –type
master link varies among chain manufacturers. Some specify as little as 0.006” and generally no more than
0.028”. This is a very small amount of flare. Do not attempt to flare the chain pin flush with the side plate, or the
chain pin can crack and be weakened, and you risk damaging the tool as well. Measure the un-flared chain pin
with a caliper, and then check the flare often with the caliper to insure you do not over-flare the chain pin. One
turn of the push bolt equals one millimeter of travel, so a typical flare will require less than a full turn.
Image F shows a properly flared hollow-nosed master link.
4-Withdraw the tool from the chain, and visually check that both chain pins show the same size flares. Check
that the riveted-on side plate is in alignment with the side plates of adjacent chain links.
* It is very important that chain master links be clipped or riveted properly. Improper installation can
lead to great bodily harm or death. If you are unfamiliar or uncomfortable with this process, please
have your work supervised by a qualified technician or bring your vehicle to a qualified facility for
repair.
