General Instructions
1. When holding a tool in a vice
always use care and copper jaws
to protect the integrity of the part
that you are holding.
2. Prior to reassembly, clean
every part using a mild solvent
to remove all grease, oil, and
debris. Apply a thin layer of
recommended air tool oil to all
motor and throttle components
as you reassemble. Coat
the impact mechanism parts
with approximately 15 cc of
recommended grease. Apply a
thin film of O-ring lubricant to all
O-rings before they are installed
on the part.
3. Check bearings to be sure
they are smooth. Push and pull
on the inner race as you turn it
while holding the outer race in
your opposite hand. If there is
any roughness noticed, replace
the bearing. Work a fair amount
of grease back into the bearing
whether reusing the old bearing
or replacing it with a new one.
4. Always press bearings by
using a drift and ONLY applying
pressure to the inner race of the
ball bearing when pressing onto
a shaft. Always press bearings by
using a drift and ONLY applying
pressure to the outer race when
pressing into a recess.
Assembly of the Motor
Housing
1. Install a new Throttle Valve
Seat by pushing it firmly into the
housing using a 13/16" drift. Be
sure that the Throttle Valve Seat is
seated all of the way down in its
recess
(see figures 20.1 & 20.2).
