seal should come off with the flange. Remove and discard the oil seal.
2.
To remove the input shaft seal:
a.
Wrap the end of a flat-head screwdriver with insulating tape to prevent damage. The
screwdriver should be approximately 0.3” tip thickness x 0.6” tip width x 6.9” length (1.6 x 8
x 175 mm).
b.
Insert the screwdriver end between the oil seal lip and the input worm shaft. Take care to
not damage the oil seal seat on the worm shaft.
c.
Use the screwdriver as a lever and use the worm shaft as a fulcrum to remove the oil seal
from its seat.
d.
Remove and discard the oil seal.

Disassembly of the Front End Gearbox
Remove components as described. Do not attempt to remove gears or bearings from shafts.
1.
Remove the motor gearbox assembly from the pinspotter. Separate the gearbox from the motor.
2.
Remove the vent plug and the lower pipe socket plug. Drain and discard the lubricating oil from the
gearbox.
3.
Remove the mounting flange and closed cap.
4.
Remove the special cap by unbolting the 4 hex cap screws (or the expansion plug by punching a hole in
it, if applicable) and prying out the cap/plug from the housing. Ensure that the inside diameter of the
