105. Remove the 3/4 gear block, and then the 2 gear gear with its bushing (see pictures).
106. Mark the relative position of the hub and the 1/2 gear synchronizer sleeve and remove them from the shaft (see pictures).
107. Remove 1st gear gear with half washers (early models) or thrust needle bearing and circlip (latest models) (see pictures).
108. Press out or protrude the shaft from the bearing on the side of the final drive gear, taking care not to damage its end.
109. Before assembling the shaft, check that there are no scratches or wear marks on it. Lubricate all parts as they are installed.
110. Install the pinion side bearing onto the shaft, using a suitable tube to press it into place. On recent models, install a new circlip.
111. Install half washers over the bearings, securing them in place with grease. On the latest models, install a thrust needle bearing instead of washers.
112. Install the 1st gear, making sure that the half washers do not move (if applicable).
113. Install the 1/2 gear synchronizer, aligning the marks made during disassembly. The chamfer on the outer teeth of the synchronizer should be on the side of the 1st gear gear.
114. Install the 2nd gear gear with its bushing.
115. Install the 3/4 gear block.
116. Install the rear bearing so that the circlip groove is on the side of the shaft end.
117. Install 5th gear (where applicable) tide towards the bearing. On early 4-speed gearboxes, install a washer, on the latter, a spacer.
118. Install a new nut on the end of the shaft, do not tighten it yet. The assembly of the output shaft is completed.
