2.1 Initial Inspection and Storage Instructions
c WARNING: Read this installation and maintenance manual carefully and completely before attempting to store the gearbox. If an electric
actuator is attached to the SB gearbox, be aware of the electrical hazards. Consult the electric actuator installation and maintenance manual
forguidance.
2.2 Inspection and Recording
Upon receipt of the gearbox, inspect the condition of the equipment, and record nameplate information.
1. Carefully remove the gearbox from the shipping carton or skid. Thoroughly examine the equipment for any physical damage that may have
occurred during shipment. If damaged, immediately report the damage to the transport company.
2. A nameplate is attached to eachgearbox with the following information:
• Gearbox size
• Order number
• Serial number
• Customer tagging
Record this information for future reference, e.g., ordering parts, or obtaining further information. 5

Sambo SB series bevel gear operator
2.3 Storage Procedure
NOTE: The following is the recommended storage procedure to retain maximum product integrity during storage. Failure to comply with
recommended procedure will void the warranty.
Storage (less than one year)
Store the gearboxes on wooden skids to protect the machined mounting flange. Placethe wooden skids containing the gearboxes in aclean, dry,
protected warehouse. If the gearboxes must be stored outside, they must be covered in polyethylene protection with silica gel crystals toabsorb
moisture. If an electric actuator is attached to the V gearbox, refer to the storage procedures in its respective manual for appropriate storage proce-
dures. Rotate input shafts every three months to mix the lubricant.
2.4 Safety Precautions
c WARNING: Read this Installation, Operation and Maintenance manual carefully and completely before attempting to install, operate or trouble-
shoot the SAMBO gearbox.
c WARNING: Potential HIGH-PRESSURE vessel — be aware of high-pressure hazards associated with the attached valve or other actuated de-
vice when installing or performing maintenance on the gearbox. Do not remove the gearbox mounting bolts from the valve or actuated device
unless the valve or device stem is securedor there is no pressure in the line.
c WARNING: For maintenance and/or disassembly of the gearbox while installed on the valve, ensure that the gearbox is not under thrust or
torque load. If the valve must be left in service, the valve stem must be locked in such away as to prevent any movement of the valve stem.
c WARNING: Do not manually operate the gearbox with devices other than the installed handwheel. Using force beyond the ratings of the gearbox
and/or using additive force devices such as cheater bars, wheel wrenches, pipe wrenches, or other devices on the gearbox handwheel
may
cause serious personal injury and/or damage to the gearbox and valve.
c WARNING: Do not exceed any design limitations or make modifications to this equipment without first consulting Mechanical Advantage
c WARNING:
Use of this product must besuspendedanytime it fails to operate properly.
a CAUTION: If a motor actuator is driving the gearbox, do not operate the valve under motor operation without first checking and setting the limit
switch and checking for correct motor rotation.
a
CAUTION: Do not use replacement parts that are not genuine SAMBO parts, as serious personal injury and/or damage tothe gearbox and valve may
result.
2.5 Safety Practices
Thefollowing checkpoints should be performed to maintain safe operation of the SAMBO gearbox:
• Set up a periodic operating schedule on infrequently used valves.
• Ensure that the limit and/or torque switches on any electric actuator fitted to the V gearbox are correctly and appropriately adjusted.
2.6 General Mounting Instructions
The mounting instructions for the SB bevel gearboxes are outlined below. The V0 through V9 gearboxes are designed with a splined top-entry Stem
Nut which is retained in the Drive Sleeve by two Lock Nuts.
6
The V35H through V9H gearboxes are designed with a Stem Nut which is retainedby two Thrust Roller Bearingswithin the Thrust Housing and
Thrust Base. Partial disassembly of the Thrust Base is required for Stem Nut removal and/or installation.

Lubrication
SAMBO SB gearboxes are shipped with the following lubricants:
Table3.1 –Lubricants
Product Lubricant Soap Base Temperature Range
V0 through V9 Zenith EPSB-2 Calcium -20°C to 200°C
V35H through V9H Zenith EPSB-2 Calcium -20°C to 200°C
NOTE : The lubricant should be checked every 18 months forgearboxes.
a CAUTION: Do not add a different lubricant to a SAMBO gearbox unless it isof the same soap base as the existing
lubricant, or you have received the approval
of the lubricant manufacturer.
Quantity
SAMBO gearboxes are built to operate on the partial immersion principle. Theprimary concern regarding the amount of
lubricant is whetherthe bevel gear assembly is totallyimmersed in grease. This can be verified by the use of one or more
of the “fill” and“drain” plugs provided on the gearboxhousing in most sizes.
Quality
When removing a “fill” or “drain” plug to inspect the lubricant level, remove a small amount and ensure that it is clean
and free of any contaminant, including water. Should dirt, water or other foreign matter be found, the gearboxs should
be flushed with a commercial degreaser/cleaner which is non-corrosive and does not affect seal materials such as
Buna-N or Viton. Repack the gearbox with fresh lubricant.
Consistency
Themain gearbox lubricant should be slightly fluid, approximating a standard NLGI-2 grade consistency or less.
Alternate lubricants may be used in place of the standard lubricants supplied by Mechanical Advantage Corporation,
provided they are of a formulation similar to those listed above for the respective product.
