Synchronizer I Check spline area of coupling sleeves, hubs and gears for I Check baulk rings for cracks or deformation. I Check insert springs for deformation. I Measure clearance between baulk ring and gear. Clearance between baulk rings and gears, Standard 1.0 - 1.35 mm (0.0394 - 0.0531 in) Wear limit 0.7 mm (0.028 in) I 2nd and 3rd gears have inner and outer baulk rings and so I Measure wear of 2nd and 3rd baulk ring. a. Place baulk rings in position on synchronizer cone. b. While holding baulk ring against synchronizer cone as far as it Standard: A 0.7 - 0.9 mm (0.028 - 0.035 in) B 0.6 - 1.1 mm (0.024 - 0.043 in) Wear limit: 0.2 mm (0.008 in) c. If dimension “A” or “B” is smaller than the wear limit, NMT022 Shifting insert Spline SMT140 Baulk ring to SMT695B Synchronizer Inner baulk ring REPAIR FOR COMPONENT PARTS RS5F32A Mainshaft and Gears (Cont’d) MT-27 |
