LGD’s mounting.
Install the LGD’s in their proper orientation with pivot gear
screws facing forward. Slide it onto the guide bar and drive shaft, then line up the
LGD with the lens gear you wish it to access.
The sequence of tightening screws on the LGD’s is important.
Step 1.
Tighten the LGD mount screw
securing it to the guide bar.
Critical
: the
drive shaft/gear hub must be centered with
the opening on the bracket.
Step 2.
Pivot the larger gear onto the lens
gear such that it makes intimate contact.
Carefully observe that the gear is still
properly aligned and the drive shaft/gear hub
is centered with the LGD bracket (see photo).
Tighten the two pivot screws gently to secure
it in position.
Step 3.
Firmly tighten the screw that couples
the drive gear hub to the drive shaft.
TIP
. The gear hub / drive shaft coupling acts
like a clutch – the drive shaft will ‘slip’ when
reaching the end of travel in either direction.
Tightening the screw more will allow less slip.
Adjust this amount of slip at your discretion.
Center the drive shaft/gear hub to the
bracket. Tighten the screw and secure
the LGD to the guide bar.
With the drive shaft/hub centered, pivot
the larger gear to make intimate contact
with the lens gear. Gently tighten 2 pivot
screws.
Couple to Drive Shaft .
