puller to remove the primary shaft 40 (see. Fig. 8.15), the inner ring of the roller bearing; Remove the puller with a primary shaft thrust washer, bearing and gear 4th gear; Remove the snap ring groove of the shaft and the gear 3rd gear. Verification carried out as follows: thoroughly clean all parts of the primary shaft and check their condition;
| Fig. 8.14. Mounting gear 5th gear on the gearbox shaft 1 - a bolt; 2 - spring washer; 3 - a conducted gear wheel of 5th transfer; 4 - a nave of the synchronizer; 5 - ring of the synchronizer; 6 - drive gear 5th gear
|
| Fig. 8.16. Check the gap "a" between the synchronizer ring and gear 5th gear
|
check the condition of the synchronizer ring 5th gear (Fig. 8.14), setting it in the sliding sleeve and pressing toward the gear 5th gear. Blade probe to measure the gap between the inner end of the ring gear and which should be no more than 0.5 mm (Fig. 8.16). Input shaft assembly sequence is as follows: when assembling the input shaft, lubricate oil Each setting item;
| Fig. 8.17. Installing the gear 3rd gear on the input shaft
|
fix the input shaft in a vice with overlays from soft material and, using tubular mandrel, set the gear 3rd gear on the shaft (shoulder on the gear to be sent to a gear wheel of 4th transfer (Fig. 8.17.); lock the gear 3rd gear retaining ring; press in shaft with a gear wheel of 4th transfer (shoulder on the gear to be sent to a gear wheel of 4th transfer);
| Fig. 8.18. Installation of the bearing on the input shaft
|
using tubular mandrel, set on the shaft tapered roller bearing (Fig. 8.18); Install the shaft with thrust washer;
| Fig. 8.19. Pressing the sleeve on the primary shaft
|
Install the plug on the input shaft and press it into place with the help of a tubular mandrel (Fig. 8.19);
| Fig. 8.20. Install tapered roller bearing to the input shaft by the clutch setting
|
using a tube, so press them tapered bearing on the input shaft from the clutch housing (Fig. 8.20); tapered roller bearing outer ring press-fit into the gearbox housing without shims; Install the input shaft to the crankcase; Collect the gearbox housing and tighten bolts to torque.
