Differential repair (Kalina 1118)

To repair the differential on a car, you will need: a 17 mm socket wrench (head), round-nose pliers or special pliers for removing retaining rings, a thin chisel, and a hammer.

1. Remove the differential (figure 5.6) from the gearbox (see "Disassembly and assembly of the gearbox and defect detection of its parts").



2. Turn the satellites 90° around the axis and remove the axle gears from the differential housing.



3. Remove the retaining ring from the satellite shaft.





4. Remove the satellite axle and two satellites from the differential housing.



5. Unscrew the bolts securing the driven gear to the differential housing.



6. Insert a chisel into the gap between the end of the inner bearing ring and the differential housing and press the driven gear off the differential housing.



7. Inspect the working surfaces of the satellites, the satellite shafts, the axle gears and the spherical surfaces of the differential housing that come into contact with them. Remove minor irregularities with fine-grained sandpaper. Replace parts with significant defects.



8. Check the condition of the driven gear of the gearbox. If there are chips, pitting or significant wear on the teeth, replace the driven gear. The vehicle can be equipped with final drive gears with different gear ratios. The number of teeth of the driving 1 and driven 2 gears is stamped on the driven gear.

Attention! At the vehicle manufacturing plant, the main transmission gears are selected in pairs based on noise and contact patch. Therefore, when replacing the driven gear, replace the drive gear as well (they are sold in pairs in auto shops). To check, count the number of teeth on the pinion gear.

9. Inspect the bearing seats on the differential housing. If these areas are significantly worn, replace the differential housing. If there is pitting (cavities) on the treadmills and rolling elements, traces of indentation of the rolling elements on the treadmills, or damage to the separators, the bearings must be replaced.





10. To replace the bearings, press them off the differential using a puller. In this case, the bearings are destroyed. Then...

11. ...press out the outer rings from the gearbox and clutch housings using a special puller. If you don't have a puller, first press out the axle shaft seals. Please note that this will damage the axle shaft seals and they will need to be replaced (see "Replacing gearbox seals"). From the outside of the gearbox housings, press out the bearing rings with a punch.



12. Please note that there may be an adjusting ring under the ring installed in the gearbox housing, which must be re-fitted before pressing in new rings (see "Selecting the differential bearing adjusting ring").





13. Assemble the differential in the reverse order of removal, after lubricating all parts with transmission oil. The driven gear must be installed with the teeth marking facing outward.
