a
CAUTION: Do not add a different lubricant to a Flowserve Limitorque gearbox unless it is of the same soap base as
the existing lubricant, or you have received the approval of the lubricant manufacturer.
Quantity
Limitorque SR gearboxes are lubricated so that all bearings and gearing/gear contact areas are liberally coated with
grease. The gearboxes do not require additional lubricant under normal operating conditions.
Quality
Remove a small amount of lubricant and inspect for any contaminant, including water. Should dirt, water, or other
foreign matter be found, the lubricant must be replaced. Partial disassembly of the gearbox will be required. Contact
Flowserve Limitorque with the gearbox order number or serial number for replacement parts, if required.
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.
