z.2. Front Panel Escutcheon Mounting
The following procedure was taken from SB-101 Assembly Manual but should apply
equally to any SB-series product using the same dial mechanism.
NOTE: If the front panel is not installed, it may be easier to mount the escutcheon to the front panel before
installing the front panel.
NOTE: If the front panel has been repainted, the paint may have added enough thickness that the tabs on the
escutcheon may no longer fit over the panel. Removing a slight amount of material on the rear side of the panel
may allow the escutcheon to be installed.
Refer to Detail 3-14A for the following steps.
Figure 9. Front Panel Escutcheon Installation
1. Place the drive' shaft bushing assembly (#455-42) over the dial drive pulley.
2. Carefully lubricate the shaft of the dial drive pulley and the center bearing of the Zero set
dial with a small amount of silicone grease.
3. Push the dial drive bushing down into the keyhole slot so the dial drive pulley engages with
the circular drive ring.
4. Snap the zero set drive pulley (small pulley) onto the zero set dial. Position the pulley and
dial as shown.
5. Mount the dial escutcheon as follows:
Start the shaft of the zero set pulley through the small hole in the escutcheon. Position the
tabs at the top of the escutcheon inside the front panel. Slide the escutcheon in place with
the dial drive bushing and shaft through the lower hole. Secure the dial drive bushing with
