Sprockets - Oregon CHAINSAW Maintenance And Safety Manual

HOW TO REPLACE OREGON
NOTE: Select a new nose sprocket with the correct pitch for your bar
and chain.
➊
Drill or punch out heads from each of the
nose-sprocket rivets. Punch out the remainder
of the rivets. Use a punch narrow enough to
keep from damaging rivet holes in the bar's
nose.
➋
Use a small screwdriver to spread the bar-
nose rails just enough to remove the old nose
sprocket. Clean out debris from the sprocket
area.
➌
Inside the nose-sprocket package you'll find
the new sprocket wrappped in a tissue.
Be careful to keep the sprocket inside the tissue
as you remove it from the package - bearings
are easily lost. Slide the tissue and the new
sprocket, together, into the bar's nose.
➍
Once fully inside the nose, hold the sprocket
in place, then remove the tissue.
