a. Inspect.
(1) The lubrication distribution system is made up of a pump, distribution units, and oil lines.
The pump moves the oil from the reservoir and applies pressure to distribute the lubricant
throughout the system. The distribution units provide branching of the oil lines and meter-
ing of the Iubricant. The oil lines carry the oil to the precise locations requiring lubrication.
The majority of the oil lines are fabricated from copper tubing. Where flexibility or recipro-
cating movement is required, nylon tubing is used. In either case, compression fittings are
used to interconnect the lubrication distribution system.
(2) The figures (2-214 through 2-220) that accompany these inspection procedures illustrate
the composition and location of the Lubrication Distribution System components. The indi-
vidual parts have been exploded for clarity and to identify joints where leaks can occur.
(3) Visually inspect lubrication system, paying particular attention to the following items:
(a) Check copper and nylon oil lines for signs of cracks or chafing in tubing.
(b) Inspect compression fittings joining oil lines, manifolds, and metering devices for leaks.
(c) Observe areas targeted by lubrication system for signs of insufficient oiling and/or wear,
indicating a blocked metering device or mis-aimed oil line.
