Pin Removal
NOTES
This method ONLY works, if the grease has a very heavy consistency and the punch
fits very tightly into the bore of the pin without binding against the sides of the pin.
The combination of the two allows the grease to be forced under the pin pushing it
out of the blind hole.
When the punch nears the end of the pin/bottom of the blind hole, remove the punch
and refill the pin with more grease.
If after several attempts of using the first method the pin has NOT moved, use the
second method to remove the pin.

Wait for penetrating oil to work. 2.
Remove excess penetrating oil. (Compressed air and shop rags.) 3.
Fill hole/pin with heavy grease. (See paragraph 5.7.2 on page 49.) 4.
Align a 1/16-in pin punch with bore in pin. 5.
Using a hammer, strike punch. (NOTE: Refill grease often as required be-6.
tween hammer strikes.)
B. Otherwise, use second method to remove pin as follows.
Using a drill and #50 drill bit, prepare bore of pin for tapping. 1.
Tap pin bore for 2-64 (UNF) threads. 2.
Use a 2-64 x 1-in screw, remove pin from blind hole as follows. 3.
