Output Shaft
Lubricate shaft, gears and bearings with recommended lubricant during assembly. Petroleum jelly can be used to hold parts in place. Check bearing surfaces of output shaft for nicks or scratches. Smooth surfaces with 320/400 grit emery cloth if necessary. Apply oil to emery cloth and shaft surface before polishing.
Inspect and replace any synchro ring if worn or damage. Immerse each synchro ring in lubricant before installation.
- Lubricate and install reverse gear needle bearing on shaft (see Fig 1). Slide bearing up against shoulder on output shaft.
- Install reverse gear over needle bearing (see Fig 2).
- Install brass synchro ring on reverse gear (see Fig 3).
- Assemble fifth-reverse synchro hub, sleeve, struts, springs and detent balls, if not previously done.CAUTION: One side of the hub has shoulders around the hub bore, this side of the hub faces the front of the shaft. One side of the sleeve is tapered the tapered side faces the front of the shaft.
- Start fifth-reverse synchro assembly on output shaft splines by hand. Then seat synchro onto shaft with a press and Cup 6310-1 (see Fig 4).
- Install new fifth-reverse hub snap ring (see Fig 5) and verify the snap ring is seated.NOTE: Snap rings are available in thicknesses from 2.00 mm to 2.20 mm (0.078 to 0.086 in.). Install thickest snap ring that will fit in shaft groove.
- Install fifth gear synchro ring in synchro hub and sleeve (see Fig 6).
- Install fifth gear bearing, spreading bearing only enough to clear shoulder on output shaft (see Fig 7). Verify bearing is properly seated.
- Install fifth gear on shaft and onto bearing (see Fig 8).
- Invert output shaft and set the shaft in Cup 6310-1 so that fifth gear is seated on the tool (see Fig 9).
- Install first gear bearing on output shaft (see Fig 9). Verify bearing is seated on shaft shoulder and is properly joined.
- Install first gear on shaft and over bearing with bearing synchro cone facing up (see Fig 10).
- Install first gear synchro ring (see Fig 11).
- Assemble 1-2 synchro hub sleeve, springs, struts and detent balls.CAUTION: The 1-2 synchro hub and sleeve can be installed backwards. One side of the synchro sleeve is marked First Gear Side. Verify this side of the sleeve is facing first gear.
- Start 1-2 synchro assembly on shaft by hand (see Fig 12). Verify synchro sleeve is properly positioned.
- Press 1-2 synchro onto output shaft using suitable size pipe tool and shop press (see Fig 13).CAUTION: Align the synchro ring and sleeve as hub the is being pressed onto the shaft. The synchro ring can crack if not aligned.
- Install interm ring.
- Install new 1-2 synchro hub snap ring (see Fig 14) and verify the snap ring is seated.NOTE: Snap rings are available in thicknesses from 1.80 mm to 2.00 mm (0.070 to 0.078 in.). Install thickest snap ring that will fit in shaft groove.
- Install second gear synchro ring in 1-2 synchro hub and sleeve (see Fig 15). Verify synchro ring is properly seated.
- Install synchro friction cone and synchro cone in synchro ring.
- Install second gear needle bearing on shaft (see Fig 16).
- Install second gear onto shaft and bearing (see Fig 17). Verify second gear is fully seated on synchro components.
- Install two-piece thrust washer (see Fig 18). Ensure washer halves are seated in shaft groove and that washer lugs are seated in shaft lug bores. Verify i.d. grooves and markings noted during removal are facing the correct direction.
- Start retaining ring around two-piece thrust washer (see Fig 19). Ensure locating dimple is between the thrust washer halves.
- Seat thrust washer retaining ring with plastic mallet (see Fig 20).
- Install third gear needle bearing on shaft (see Fig 21).
- Install third gear on shaft and bearing (see Fig 22).
- Install third speed synchro ring on third gear (see Fig 23).
- Assemble 3-4 synchro hub, sleeve, springs, struts and detent balls.
- Start 3-4 synchro hub on output shaft splines by hand (see Fig 24).CAUTION: The 3-4 synchro hub and sleeve can be installed backwards. One side of the sleeve has grooves in it. This side of sleeve faces the front of the shaft.
- Press 3-4 synchro assembly onto output shaft with shop press and suitable size pipe tool (see Fig 25).NOTE: Place the pipe on hub as close to output shaft as possible without contacting the shaft splines.
- Install 3-4 synchro hub snap ring (see Fig 26) and verify snap ring is seated.NOTE: Snap rings are available in thicknesses from 2.00 mm to 2.30 mm (0.078 to 0.090 in.). Install thickest snap ring that will fit in shaft groove.
- Install output shaft bearing.
- Secure output shaft as necessary. Install output shaft bearing snap ring, spreading it just enough to install it. Verify snap ring is seated in shaft groove (see Fig 27).
- Verify position of synchro sleeves before proceeding with assembly operations (see Fig 28). Grooved side of 3-4 sleeve should be facing forward. First gear side of 1-2 sleeve should be facing first gear. Tapered side of fifth-reverse sleeve should be facing forward.
