 B. Lubrication of the MLG
 NOTE : Use the Figures together with the Tables that follow, to find the
____
 greasers.

 NOTE : In the step that follows, make sure that the Materials No. 04-004
____ and No. 04-022 are not mixed together. Do not use them at the same time (Ref. SIL 12-008).
 (1) Lubricate the remaining greasers of the MLG as follows:
