Inspect parts IAW General Maintenance Instructions (WP 0162).
Inspect beam bushings. Maximum I.D. is 2.03 inch (51.64 mm). If I.D. is greater than limit, replace bushings.
Inspect outrigger beam pins. Minimum O.D. is 1.964 inch (49.89 mm). If O.D. is less than limit, replace pins.
Inspect pad pivot bolt. Minimum O.D. is 1.230 inch (31.24 mm). If O.D. is less than limit, replace bolt.
Inspect pivot bolt bushing. Maximum I.D. is 1.275 inch (32.39 mm). If I.D. is greater than limit,
replace outrigger beam.
END OF TASK
Liquid nitrogen is extremely cold, having a temperature of -320°F (-195°C). Wear protective
gloves that will not absorb liquid nitrogen. Excess liquid nitrogen must be disposed of promptly
since liquid nitrogen will condense oxygen from the atmosphere. The mixture of liquid nitrogen
and liquid oxygen is a powerful oxidizer and may react violently with easily oxidizable
substances. Failure to follow this warning may cause injury or death to personnel.
Cool bushings to -320°F (-195°C) submerging bushings in liquid nitrogen.
Submerge four bushings (Figure 3, Item 10), in liquid nitrogen to cool them. Apply threadlock sealant to
outrigger bushing beam bore.
Using a press, install four chilled bushings (Figure 3, Item 10) in beam (Figure 3, Item 1).
Stake beam as indicated in Figure 2.
