LUBRICATION GUIDE
For proper maintenance of Bally game, all moving parts of all units, excepting as noted
below, should be lubricated with the light MBI Instrument Grease supplied with games and
available through Bally Distributors or the Bally Service Department.
CONTACT PLATES
Contact Plates, either rivet type or printed circuit type, should be lubricated with a very
light application of LB550X Oil, which is also available through Bally Distributors or Service
Department.
CAUTION
Use of other type lubricant than LB550X Oil on Contact Plates may cause failure III
circuitry.
MOTOR GEARS
All enclosed motor gears are factory lubricated and need no further maintenance.
MOTOR ROTOR BEARINGS
Rotor Bearings should be lubricated with a No. 1 (light) oil, through the oil tubes. Avoid
use of an excessive amount of oil on Rotor Bearings.
PLUNGERS, SOLENOID
Do not lubricate Solenoid Plungers.
A scheduled and thorough maintenance program will repay many
times the cost in trouble-free operation and minimum wear of parts.
