Bulletin Number: 03-73-14; Date: 03/10/14 Page 2 SERVICE PROCEDURE / INFORMATION • Remove and disassemble the transmission as necessary to access the reverse idler gear assembly following the procedure outlined in the applicable Service Manual. • Once removed from the case, disassemble the old reverse idler gear assembly. • After a thorough cleaning and inspection of the parts to be reused, re-assemble using the exploded view below as a guide. The friction plate and snap ring are not selective parts. • After the new reverse idler assembly is back together with the new gear and spring, hold the idler gear stationary then rotate the sub gear COUNTER-CLOCKWISE (left) 2 teeth to set the “pre-load” and hold it in that position. NOTE: You will need a helper for the next step. • Using a piece of mechanic’s wire as shown below, left, wrap it around 2 pair of gear teeth (main and sub gear) and twist the ends of the wire together to hold the sub gear in position and maintain the pre-load. Since the new reverse idler gear only has one hole (used by one end of the spring), the mechanic’s wire serves the function of the alignment pin used on the original gear which had the second hole in it. • Once the assembly has been reinstalled in the case as shown below, right, cut and remove the mechanic’s wire. • Complete the reassembly following the procedure outlined in the applicable Service Manual.
