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).

Aworn 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.
