2. Remove the bolts from the shift housing. If necessary, push the housing slightly to separate it from the gear housing and then slide the shift housing out of the gear housing. Remove the shims.
3. Carefully pull the 3/4 shift rod out of the housing until the small lock piston can be removed. Be careful not to pull the rod out any further than necessary, as this may cause the synchronizer hub lock crackers to pop out.
4. After removing the plunger, insert the shaft back into the neutral position. If the synchronizer hub lock crackers pop out, the rod will not go back in.
5. Move the upper gear shift rod away from the reverse gear switch and lower it to the 1st gear switch. By engaging two gears at once, the shafts will be locked and the gear nut can be unscrewed.
6. Remove the snap ring and thrust washer from the end of the input shaft.
7. Using a special extractor, remove the input shaft bearing from the housing fastener. If you do not have a tool, you will need to remove the input shaft and pinion shaft at the same time later.
8. Remove the bolts securing the bearing housing, separate the bearing housing with the input shaft and output shaft from the main gear housing.
9. Pull the locating pins back until they are flush with the connector surface.
10. Clamp the gearbox in a vice. Support the free end of the 3/4 gear selector shaft by wedging the block from below, remove the cylindrical pin of the selector shaft. If the free end of the shaft is not supported when pressing out the pin, the hole for the shaft in the fastening element of the mechanism may be damaged.
11. Pull out the 3/4 selector shaft until the 3/4 selector fork can be removed. Then push the shaft back into neutral.
12. Remove the input shaft assembly.
13. Push out the reverse gear shaft, remove the reverse gear and the pick-up segment (if any).
14. Drive out the cylindrical pin of the ½ gear mechanism, remove the clamp from the selector shaft.
15. Knock the output shaft out of the bearing. When doing this, check that the 1/2 gear selector shaft is not jammed, if necessary, tap the shaft lightly to release it. Remove the tapered roller bearing race after removing the shaft.
16. Disassemble the gearbox housing as follows. First insert a suitable rod through one of the drive flange bolt holes so that the rod is against one of the cover ribs and prevents the flange from rotating. Then remove the flange center bolt. Repeat the action on the other drive flange, remove the flange shafts. Mark each shaft so that they fit correctly in the gearbox housing.
17. Remove the ten differential housing bolts, remove the cover, and disconnect the differential.
