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.
