Adjusting Transmission Gear Lash (play)
Check the transmission gear lash, between the metal transmission gear and the delrin hook shaft gear.
Note: Do not adjust this unless you are sure it needs adjusting. This will affect the timing of the
machine
. There should be little or no lash between the two gears. If correction is necessary:
•
Loosen the two screws in the elongated slots on the transmission housing above the gear.
(4mm Allen tool)
•
Adjust the transmission mount with elongated slots up (for more lash) and down (for less lash)
until has the least amount of gear lash and noise.
NOTE: The transmission housing is pushed to the right towards the hand wheel end of the machine,
until flush with the machined edge while being adjusted.
•
Tighten the two transmission housing screws.
•
NOTE: Improper adjustments of this setting will cause timing and noise problems.
