INSTALLATION Proper installation of MASTER speed reducers will ensure reliable service and maximum life. Key items to minimize possible failures include: Gear Case Mounting To insure uniform pressure mount gear case on flat surface. Use uniform torque when mounting bolts are tightened. Shaft Overhung Loads Excessive overhung loads due to over tightening of belts or chains can result in broken shafts and reduced bearing life or failure. Couplings Improper coupling alignment can result in excessive stresses on gear unit shaft and bearings. Shock Loads Excessive shock loads can also result in damaging stresses on shafting and bearings. LUBRICATION - RIGHT ANGLE This gearcase has been lubricated at the factory for only one mounting position. Before starting, check the mounting position diagrams in Instruction Manual E--3614, pages 6 through 9 to make sure that the oil level plug and oil level are in the correct location for which the unit is to be operated. This is extremely important, as insufficient lubricant will damage gears and bearings in a very short time. If any change is necessary, the vent plug must he relocated above the new oil level. When the unit is to be mounted in a position other than those shown in the diagrams, consult the factory. Units mounted with output shafts in the vertical position require street ells to raise the oil level to the top edge of the bronze worm gear. On some sizes this street ell is shipped separately to avoid breakage in transit. The location for the street ell is indicated by an instruction tag wired to a throwaway plug (a throwaway plug can be recognized by the cross-drilled hole in the head of the plug). Before putting unit into operation turn the unit up so that oil will not drain out when the throwaway plug is removed. Remove and discard the throwaway plug and install the street ell in a vertical position as indicated on the mounting position diagrams in Instruction Manual E--3614, pages 6 through 9. The unit is factory-filled with the proper amount of lubricant to bring the oil level to the top of the street ell. On some mounting positions zerk fittings are provided for grease lubricating bearings located above the operating oil level. Lubricate with a good grade of roller bearing grease when changing gear lubricant at the recommended change interval. Texaco Marfak No.3 is a suitable grease. Do not overlubricate grease-packed bearings. Single reduction worm gear units for output shaft down mounting have one pipe-tapped hole in the center of the closed bearing housing. Combination units for output shaft down mounting have two pipe-tapped holes in line, one in the center of the output shaft and one in the center of the second stage pinion shaft. Units are shipped from the factory with throwaway plugs in these tapped holes (a throwaway plug can be recognized by the cross-drilled hole in the head of the plug). Before putting units into operation remove and discard the throwaway plugs and install the zerk fittings. Flanged units for the flange/output shaft up mounting have two pipe-tapped holes in the side of the flanged bearing housing. One of these holes is for a zerk fitting. Its location can be recognized by the throwaway plug. Remove and discard the throwaway plug and install the zerk fitting. CAUTION PROPER OPERATION OF THIS UNIT REQUIRES VENTlNG. REPLACE THE THROW AWAY PLUG WITH VENT PROVIDED. FAILURE TO OBSERVE THIS PRECAUTION COULD RESULT IN DAMAGE TO OR DESTRUCTION OF THE EQUIPMENT. Vent plug locations can be recognized by a throwaway plug. The vent plug is wired to the throwaway plug to avoid mistaking it for a zerk location. The vent plug is designed to prevent dirt and water from entering the gearcase and also to release air pressure caused by heat generated in the case. Without proper air venting the increase in pressure may force lubricant through the oil seals and result in oil leakage and damage to the unit. Do not restrict the operation of the vent with paint or other obstructions. NOTE: Standard vents are spring loaded which open at approximately.50 P.S.I. If sight gauges are installed on a gear unit, the vent must be a type which is open continuously. OPERATING TEMPERATURES Heating is a natural characteristic of right angle gear units with a worm gearset. A maximum gearcase sump temperature approaching 200 F. is not uncommon for units operating in normal ambient temperatures. When operated at the rated capacity, no damage will result from this temperature, as this was taken into consideration in the design of the gearcase and the selection of the lubricant. The proper lubricant must be selected for the operating ambient temperature range, with seasonal changes in lubricant viscosity grade whenever necessary. Output speeds above 300 RPM may require a lighter viscosity grade of lubricant. Select the lubricant from the proper column on page G6--67. Lubricants other than those listed should not be used without specific factory approval as performance or gear life may be adversely affected. G6--66
LUBRICATION RIGHT ANGLE (CONT.) Lubrication is extremely important for satisfactory operation. The proper oil level must be maintained in the gearcase at all times. The correct level is indicated by the red head pipe plug. Frequent inspections with the unit not running (preferably when warm), should be made by removing the plug to see that the level is being maintained. If low, (without replacing oil level plug), add lubricant through one of the proper holes until it comes out of the oil level hole. Replace the oil level plug securely. grit and metal particles from the run-in period. Lubricant should he drained, the gearcase flushed with mineral spirits and refilled after the first 250 hours of operation; then every 1300 hours or six months thereafter, whichever occurs first. (Normal operation is running 16 hours per day in 80 F. ambient). More frequent oil changes may be necessary when running continuously at high temperatures. Use only recommended lubricants as listed in the table below. NOTE: If Mobil SHC-629 or SHC-634 are used for normal operation (viscosity group 318.62), the time for changing the lubricant may be extended. Drain, flush, and refill after the first 1500 hours of operation: then every 5000 hours thereafter. (SHC is a registered trademark of the Mobil Corporation). APPROVED LUBRICANTS VS. AMBIENT CONDITIONS: The satisfactory performance of gears and bearings in gearmotors and reducers depends on clean lubricant, free from dust, grit, sludge, and moisture. Depending on operating conditions, the lubricant will eventually become contaminated and should be replaced periodically. When first put into operation, the lubricant in new gearcases becomes contaminated with AMBIENT LUBRICANT VISCOSITY GROUP VS. OUTSHAFT SHIPPED TEMPERATURE UP TO 300 RPM OVER 300 RPM -65 F.

LUBRICATION-RIGHT ANGLE (CONT.) RECOMMENDED LUBRICANTS It is impossible to select one gear lubricant of petroleum origin which is usable over a wider range of temperatures such as minus (-)65 F. to plus (+)165 F., as is required for some installations. When such conditions are encountered it is necessary to change the lubricant depending on the ambient (surrounding air) temperature at the time of operation. Use lubricants of the proper viscosity group as outlined in the previous table. Note 1. Lubricants shipped in the gearcase from the factory are viscosity group 318.62 oils for standard ambient conditions and continuous duty. Note 2. If a USDA-HI food grade lubricant is desired, Chevron FM lubricating oil 460X may be used in ambient temperatures of +15 F to +110 F. Chevron FM lubricating oil is available as a factory fill, but if it becomes necessary to install this oil in the field by draining a gearcase which contains our standard non-food grade lubricant the gearcase must be flushed thoroughly before installing the new oil. Do not operate gear unit in ambient temperatures below -65 F. nor above +165 F. For temperatures below -10 F. special oil seals are required and bearings in the gearcase must be packed with Aeroshell 7 grease instead of Marfak No. 3. All group 318.63 lubricants, except Mobil SHC-634 must be changed after 300 hours of high temperature operation. Mobil SHC-634 must he changed after 1500 hours of high temperature operation. When changing oil from one viscosity group to another, flush the gearcase with mineral spirits before installing the new oil.

The reducers require nitrile seals, hytrel coupling spiders, and low temp lubrication along with XT construction. The gearmotors require nitrile seals, low temp lubrication, XT construction and motors with low temp grease. G6--68
