GASOLINE. DO NOT SMOKE OR BRING FIRE OR
FLAME NEAR THE FUEL.
2) Position the Hole Digger on a suitable work bench
with the operator handle level with the ground. As an
alternative, the transmission driveshaft can be securely
mounted in a suitable bench vice. Wipe any dust or dirt
from the area where the transmission separates.
3) Loosen and remove the four nuts that retain the
engine and operator handle to the transmission.
Separate the engine from the operator handle from the
transmission and store in a position that does not
damage the throttle cable.
4) Loosen and remove the six capscrews that fasten
the transmission together. Using the rubber hammer,
split and separate the transmission cover and case.
Exercise caution not to damage the dowel pins. If the
bearing journals of the secondary pinion, PN 210-
0310, are difficult to remove from the ball bearings,
remove the PN 37040200 Screw from both housings.
Insert a 1/4-20 UNC capscrew into the housing. Using
the wrench, rotate the capscrew to thrust against the
pinion journal until it clears the pinion gear support
bearing. Repeat the process with the remaining pinion
gear bearing journal if necessary. FIGURE 20. Remove
the PN 240-0100 Gasket. Remove the primary gear
and pinion assembly, PN 240-0340 and PN 210-0310.

5) If it is determined the transmission grease should be
replaced refer to CHANGING THE HOLE DIGGER
TRANSMISSION LUBRICANT in the Service section
of this manual for additional information.
6) The PN 210-0320 Pinion Gear is threaded on to the
clutch drum shaft. The threads are right hand rotation.
Using the impact wrench and 12 point, 25/32 inch
socket, remove the pinon gear from the clutch drum
shaft. FIGURE 21.
7) Using the rubber hammer, tap against the threaded
shaft until it is clear of the transmission cover. If
additional force is required, support the cover to
prevent damage in a suitable arbor press. Apply a
direct force against the threaded shaft until the drum
and shaft clear the transmission cover. FIGURE 22.
WEAR SAFETY EYEWEAR AND APPROPRIATE
APPAREL WHEN DISASSEMBLING THE CLUTCH
DRUM AND SHAFT FROM THE TRANSMISSION
COVER. FLYING DEBRIS CAN RESULT IN
PERSONAL INJURY.
