HOW TO REPLACE NOSE SPROCKETS ON
PRO-LITE
®
, AND MICRO-LITE™ PRO BARS
Select a new nose sprocket with the correct
pitch for your bar and chain.
1. 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.
2. 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.
3. Inside the nose-sprocket package
you’ll find the new sprocket
wrapped 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.
