Operating instructions for SAMBO Bevel
Quantity
SAMBO gearboxes are built to operate on the partial immersion principle. The primary concern
regarding the amount of lubricant is whether the bevel gear assembly is totally immersed in grease. This can
be verified by the use of one or more of the “fill” and “drain” plugs provided on the gearbox housing 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
The main 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 Flowserve, provided they are
of a formulation similar to those listed above for the respective product.
