| Special tools and workshop equipment required |
| t
| Case of tools for repairing gearboxes -U-40200- |
| t
| Case of tools for repairing gearboxes -U-40300- |
| t
| Pincer extractor tool with grippers -T20022- |
| Dismount the outer track of the tapered roller bearing |
Note! | The procedure and the tools needed for dismounting the outer tracks of the tapered roller bearings are the same in the gearbox casing and in the clutch casing. |
| –
| Extract the outer track of the tapered roller bearing from the gearbox casing with tool -U-40200/10- and -U-40300/14-. |
|
|
|
| Assemble the outer track for the tapered roller bearing |
Note! | The procedure and the tools needed for assembling the outer tracks for the tapered roller bearings are the same as for the gearbox casing and the clutch casing. |
| –
| Assemble the outer track for the tapered roller bearing in the clutch casing using tool -U-40200/10- and tool -U-40300/12-. |
|
|
|
| Dismount the tapered roller bearing |
| –
| Place tool -U-40300/13- on the differential. |
| –
| Place the extractor tool -U-40100/1- over the -U-40300/13- trying to ensure that the grippers are inserted in the notches that are located in the differential box. |
| t
| If the bearing holder is broken during the extraction process, use tool -T20022- for extracting the inner ring from the bearing. |
|
|
|
| Assemble the tapered roller bearing |
Note! | Before assembling the bearing in the differential box, heat it to approximately 100º with the electrical blower -SAT 1416-. The temperature may be checked with the digital thermometer -SAT 4002-. The procedure and the tools needed for assembling the tapered roller bearings are the same on both sides of the differential box. |
| –
| Assemble the pinion for working the speedometer. |
| –
| Place the tool -U-40300/13- into a press. |
| –
| Place the differential unit over the tool-U-40300/13-. |
| –
| Place the tool -U-40300/11- with side B facing towards the bearing, over the differential unit. |
| –
| Work the press until the tapered roller bearing is mounted in its position. |
|
|
|
| Assemble sun gears and planetary gears |
| –
| Impregnate the friction washers with gear oil and assemble in the differential housing. |
| –
| Fit the differential side gears -A- and attach them with the coupled flanges -B-. |
| –
| Introduce a planetary gear and turn it 180°. |
| –
| Place a second planetary gear opposite the first. |
| –
| In this position, turn the planetary gears towards the inside of the differential housing by means of the coupled flanges until they coincide with the holes in the planetary gear shaft. |
| –
| Insert the planetary gear shaft until it goes through the first planetary gear. |
| –
| Assemble the threaded parts to secure the coupled flanges and completely insert the planetary gear shaft right to its final position. |
| –
| Attach the spring pin to secure the planetary gear shaft. |
