b) Position the dial indicator to measure run out on
the internal hexagon bushing of the outboard bearing.
Maximum run out (as measured by the dial indicator
gauge) is + - .015 inches (.381 mm). FIGuRE 51.

6) Run out measurements that exceed these limits
may suggest that the driveshaft is bent. A bent
driveshaft will accelerate bearing wear and failure while
contributing to uneven flail cutting action. under certain
circumstances, a bent driveshaft can be removed and
straightened in an arbor press. See the SERvICE
section for specific information pertaining to replacing
the driveshaft. If the straightened driveshaft still exceeds
the established run out limits after re-assembly, it must
be replaced with a factory approved, replacement
part.
ENGINE SERVICE
Application: SP684 SURFACE SHARK
Consult the material supplied by the engine
manufacturer for specific service and maintenance
information regarding:
1) muffler
2) spark plug
3) air filter system
4) carburetor adjustment
5) ignition system
6) short and long term storage
7) maximum governed engine speed
8) emission standards
Keep this information stored with the operator Manual
for the Surface Planer so it will always be available for
use when the engine requires service or maintenance.
A properly maintained engine will add considerably to
the service life and overall productivity of the Surface
Planer.
because the planing process produces high levels
of random vibration, it is essential that the maximum
governed engine speed be checked at regular,
established intervals. Excessive engine speed can
produce vibration induced forces that can dramatically
affect component service life. Stress related cracking
and resulting failure to mufflers, blower shrouds,
belt guards and other components can result from
excessive engine speed.
