9-4. TRANSFER REPAIR (Contd)
8. Inspect three flanges (2) for twisted splines, cracks, breaks, bent or missing dust covers, and scoring
on sealing surface. If sealing surface of wear sleeve (1) is scored, replace wear sleeve (1). If no wear
sleeve (1) is present, install wear sleeve (1). Follow instructions in wear sleeve kit (part number
5705699) for removal and installation of wear sleeve (1). Replace flanges (2) if damaged.
9. Inspect synchronizer (3) for shift operation when lubricated. Collar (4) must move to three detent
positions. Shifting from HI or LO range to NEUTRAL must be easier than from NEUTRAL to HI
or LO range. Synchronizer (3) must slide easily on splines of input shaft (5). Replace damaged
synchronizer (3) as an assembly.
10. Measure internal diameter of two sprag races (6). Refer to table 9-2, Sprag Race, Brakedrum, and
Shifter Shafts Wear Limits, for measurements. Replace if worn beyond wear limits.
11. Inspect brakedrum (7) for cracks, breaks, and scoring. Replace brakedrum (7) if cracked, broken,
or scoring is over 0.031 in. (0.79 mm) deep. Brakedrum (7) can be repaired to wear limit. Refer to
12. Inspect sprag shifter shaft (8) for bends, cracks, damaged threads, scoring on seal area, and burred
setscrew hole. Measure outside diameter at straight end and at seal area. Refer to table 9-2, Sprag
Race, Brakedrum, and Shifter Shafts Wear Limits, for measurements. Repair to replace sprag
shifter shaft (8) if damaged or worn beyond limits.
13. Inspect range shifter shaft (9) for bends, cracks, burred detent grooves (10), burred setscrew hole,
and scoring at straight end and seal area. Measure outside diameter at seal area and straight end.
Refer to table 9-2, Sprag Race, Brakedrum, and Shifter Shats Wear Limits, for measurements.
Minor grooving by detent ball on lands between detent grooves (10) is acceptable. Repair or replace
range shifter shaft (9), if worn beyond limits or damaged.
