NOTE: A standard 10,000 PSI (69 kPa) 16 ounce (475 mL) grease gun delivers approximately 0.04 oz.
(1.18 mL) of grease with each pump, and a 24 oz. (710 mL) gun delivers approximately 0.06 oz. (1.77
mL) of grease. The number of pumps listed represents approximately 20% of the total grease
cavity volume in the end shield.
