IMPORTANT:
These instructions are provided as a guide only. Always refer to the motorcycle manufacturer’s service instructions,
or a proprietary manual, to establish the current procedure and data, also any warnings or cautions particular to the motorcycle.
Before commencing work, ensure that the tool is suitable for the selected chain size and connecting link. Ensure that the new
connecting link is of the same size and type as the chain to be connected. The pins in this set are consumable parts and therefore not
covered by the warranty. When selecting a pin, ensure that it is not too big for the chain pin, as it may jam in the chain, or too small, as it may
break.

DiSaSSeMbling a cHain
note:
Grind the rivet head on no. 520 and greater chains.
4.1.1.
Fit a suitably sized pin for the size of chain, into the pin holder (fig.2.2). Ensure that it is pushed fully home. Ensure that the pin
holder is wound back into the body to allow enough space for it to fit around the chain.
4.1.2.
Position the matching sized anvil into the aperture in the U holder and place the U holder over the chain link to be removed (fig.2.1).
4.1.3.
Slide the pin holder body onto the U holder and tighten the securing screw in position A (fig.2.3).
4.1.4.
ensure that the chain link is correctly positioned against the hole in the anvil at the rear of the U holder, and screw in the pin holder
until the pin is touching the face of the chain link pin to be removed. Check that everything is lined up.
4.1.5.
Use a 27mm spanner to hold the pin holder body and a 19mm spanner to turn the pin holder. Turn the pin holder clockwise and
proceed to start pushing out the link pin from the chain. Re-check that all parts are lined up and that the pin is centred on
the link pin. Continue to push out the link pin (fig.2.4).
note:
If excessive resistance is felt initially and there is difficulty in turning the pin holder, the pin may be too large for the link pin. Try one
size smaller pin and anvil if possible.

preSS fitting link plate
4.2.1.
Connect the two ends of the chain with a new connecting link.
note:
ensure that o rings are correctly positioned between the plates, and that the plates are adequately lubricated - see manufacturer’s
instructions (fig.5).
4.2.2.
Position the U holder over the link so that the end of the plate’s pins fit into the 2 recesses (fig.3.2).
4.2.3.
Fit a suitably sized pin into the pin holder and position the plate holder over the end of the pin (fig.3.3).
4.2.4.
Slide the pin holder body onto the U holder and tighten the securing screw in position A (fig.3.4).
4.2.5.
Screw in the pin holder so that the plate holder is in contact with the new link (fig.3.5).
4.2.6.
Use a 27mm spanner to hold the pin holder body and a 19mm spanner to turn the pin holder. Turn the pin holder clockwise and
proceed to start push fitting the link plate onto the pins (fig.3.6). Back off the pin holder and remove the plate holder, then follow
the instructions for riveting in 4.3.3.
