TM    5-3895-369-14 (21) Note +, -, or 0 etched on bottom of both new and original ring and pinion gear sets. Adjust shim thickness to compensate for the difference  between  both  figures  as  shown  in Table  5-4,  Pinion  Markings.  Use  Table  5-4 as   follows: PINION  ETCH (a)   Locate   +,   -,  or 0 number, from bottom of original pinion shaft, in appropriate column in Table 5-4. MATCHED   SET (b) Locate +, -, or 0 number, from bottom NUMBER of  new  pinion  shaft,  in  appropriate column in Table 5-4. (c) Find the box where original and new numbers   intersect. (d) Either add to, or subtract from, original shim build-up as recorded in step (20). For example: If the  original  pinion  shaft  is  etched  +2,  and  new  pinion  shaft  is  etched  -1,  subtract  0.003  inch (0.076 mm) from total thickness of original shims. Remove or replace shims as appropriate. Table 5-4.
