Joining Saw Chain - Oregon Harvester Handbook

Joining Saw Chain

Only use NEW Oregon replacement parts that are the
correct size and type to join and repair Oregon saw chain.
Oregon replacement parts are not designed for use in
other manufacturers' saw chain.
• Joining a loop of saw chain at a cutter is not recommended;
only join your saw chain at a tie-strap location .
• The rivet head must be snug and secure while allowing all
joined parts to move freely .
• For best results with Oregon Harvester Saw
Chain, we recommend using the Oregon
Heavy-Duty Rivet Spinner to spin the
chains . Consult with your local
Oregon dealer to acquire a
Heavy-Duty Rivet Spinner
(24539-SI) .
1 . Place the preset tie-strap on a flat outer surface of a saw
chain breaker anvil . Be sure the rivets are pointing up .
a . Do not use a
hammer to form
rivet heads for
Oregon .404"-pitch
harvester saw
chain .
b . For Oregon
3/4"-pitch
harvester saw
chain, it is
recommended to
strike the rivet once after assembly before spinning .
Make sure to only strike the rivet .
2 . If you're replacing a cutter, break at the tie-strap location in
front of and behind the cutter you're replacing .
