7) Repeat Step 5 to determine that  alignment did not 
change while tightening the fasteners. If alignment did 
change, repeat Steps 2 thru 6 until satisfactory results 
have been achieved. 
 
CHECKING DRIVESHAFT RUN OUT. 
Application: All Models. 
Tools Required: 
1 each, 3/4 inch wrench. 
1 each, dial indicator and magnetic base. 
 
Parts Required: 
1 each, PN 29020-015 driveshaft (if required). 
 
Proper driveshaft run out limits are essential to 
produce an even cutting action by the flails. Driveshaft 
run out limits are measured with the use of a dial 
indicator for accuracy. 
 
1) Position the Floor Planer on a suitable work 
surface. If the engine is not to be removed, fuel and oil 
must be drained from the fuel tank and crankcase. The 
normal position for checking driveshaft run out is with 
the main frame perpendicular to the work surface. 
Support the unit with proper blocking. 
2) Using the 3/4 inch wrench, remove the capscrews 
that retain the access door to the main frame.  
 
3) Clean  and remove any excessive material build-up 
from the threaded bosses and surrounding area. 
Material build-up can affect the driveshaft run out.  
 
4) Remove the flail drum and replace the access door. 
Tighten the capscrews with the wrench until the 
access door is secured. 
 
5) Install the dial indicator with the magnetic base 
attached to the main frame. Driveshaft run out can be 
measured by the dial indicator  at two locations: 
 
a) Position the dial indicator to measure run out on the 

driveshaft flange. Maximum run out (as measured by 
the dial indicator gauge) is + - .010 inches (.254 mm). 
A worn flange surface may not allow  an  accurate 
measurement to be taken. FIGURE 54.

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  55.

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.
