9.12 LEADSCREW SHEAR PIN
Safety feature:
The transmission is protected against severe overload by
a shear pin fitted into the leadscrew drive, just beside the
right hand of the gearbox.
To replace a shear pin:
1. First disengage drive to the leadscrew by setting the
right-hand lever of the gearbox to the position W or X.
2. Move the shroud washer with snap ring right-ward to
the spring cover.
3. Then rotate the leadscrew by hand carrying the bro-
ken pin to the frontview, on same level to the slot of
flanged bearing.
4. With a magnetic screw driver, remove the broken
pin head from the collar, and other broken pin from
gearbox housing slot hole.
5. Align the holes in flanged-shaft, collar and shroud
washer, then insert a new pin and turn the shroud
washer half circle towards the left to the collar with
snap ring to retain the new shear pin.
