c. 0.020" Brake Adjusting Shim (Siemens' part number NYK:074070-D)
d. S-80 Lock Bar part number NYK:074035-X40
The following is a list of tools, recommended but not provided, with the gate mechanism:
1-1/2" wrench (main shaft to hub nuts)

6.2
PERIODIC LUBRICATION
The S-80 Gate Mechanism has sealed bearings on the main shaft, on the idler gear shafts, and
on the auxiliary sidewalk arm shaft, if so equipped. No bearing lubrication is required.
Gearmotor bearings are sealed with all temperature grease and no lubrication is required.
Gears should be coated with a thin film of all temperature grease such as Aeroshell
grease is applied at the factory, so no initial lubrication is required during installation. Siemens
requires that the gears be thoroughly cleaned and have grease reapplied annually. For
gates used in extremely high-volume applications, in excess of 100,000 operations per
year, Siemens recommends that grease be reapplied every 6 months or when signs of
gear wear become evident.
6.3
PERIODIC INSPECTION
Ensure that air vents are kept unobstructed and flexible conduit between gate mechanism and
the junction box base is kept sealed.
