A set of two bearings, cones and a
grease seal is around $16 for 1-inch axles.
An example is the
grease seal, NSN 5330-00-849-4366, for the CH-47, shown in Fig 182-2, TM 55-1520-240-23-P.
Powered by a 13-horsepower gasoline engine, the efficient constant
grease seal pump delivers 20 percent more fluid capacity than the MM9 fluid system, moving 42 viscosity slurry at the rate of 200 gpm.
"During our first incident, the
grease seal didn't allow the lubricant to escape while doing preventive maintenance (PMS), causing the sheave to seize," said Caldwell.
For example, a
grease seal that formerly went to a drill press and then to a milling machine now is completed by the Arrow 750 with savings of 20 min/part.
