Component Disassembly & Reassembly: MAINSHAFT: Reassembly
- To check mainshaft 2nd gear-to-3rd gear clearance, install proper components, except "O" rings and mainshaft 4th gear on mainshaft. Perform STEP 1. See Fig 1.
- Install used mainshaft lock nut on mainshaft. Tighten mainshaft lock nut to 22 ft. lbs. (30 N.m). Hold mainshaft 2nd gear against 2nd clutch.
- Using feeler gauge, measure clearance between mainshaft 2nd gear and mainshaft 3rd gear. Perform STEP 2. See Fig 1. Replace thrust washer, located between mainshaft 2nd gear and 2nd clutch, if mainshaft 2nd gear-to-3rd gear clearance is not .002-.005" (.05-.13 mm). Different thickness thrust washers are available. See TORQUE SPECIFICATIONS table. Replace thrust washer and recheck mainshaft 2nd gear-to-3rd gear clearance.
- Once correct thickness thrust washer is obtained, lubricate all components with Dexron-II ATF. Reassemble mainshaft.
- Ensure thrust needle bearings are installed with unrolled edge of bearing retainer facing washer. Before installing NEW "O" rings on mainshaft, wrap splines with tape.
