A) Without replacement of tensioning bush. Removal of final drive cf. 33 10 010. Drain oil. Fasten final drive on support 6003-1 and unscrew oil drain plug (1).  33 10 010

Remove locking plate. Measure overall frictional value and note. Important: When fitting, the overall frictional value measured plus the frictional value of the new shaft sealing ring must be reached, but not exceeded. |  |
Using a centre punch, mark collar nut in relation to pinion. Using clamping tool 7012, secure drive flange and unscrew collar nut. |  |
Using pulling tool 7019, pull off drive flange. |  |
Using pulling tool 7051, pull out sealing ring. |  |
Turn collar nut on drive pinion. Measure frictional value and note. |  |
Force on sealing ring until the surface are flush. Fill sealing ring projections with grease. Using tool 7026, force drive flange into position. Tighten collar nut by hand. Measure frictional value and note. |  |
Measure new overall frictional value. Example: Frictional value 9.0 cmkp (0.6507 ft/Ib) with new sealing ring Frictional value without sealing ring - 6.0 cmkp (0.4338 ft/Ib) -------------------------------------- 3.0 cmkp (0.2169 ft/Ib) Plus overall frictional value prior to disassembly + 25.0 cmkp (1.8075 ft/Ib) New overall frictional value ----------------------------------------- 28.0 cmkp (2.0244 ft/Ib) ------------------------------------------ Tighten collar nut until mark made with centre punch is reached and then measure frictional value. Important: The minimum tightening torque of collar nut (1) is 15.0 mkg (108.45 ft Ib). If 15.0 mkg (108.45 ft Ib) is not reached of if the newly- measured overall frictional value is exceeded, replace tensioning bush (2) and repeat measuring process. Secure collar nut in position by means of locking plate. Fill in oil. |  |

Mark position of drive flange when fitted. Remove locking plate. Note when fitting: Secure collar nut in the groove of the drive flange by means of the locking plate. |  |
Measure frictional value and note. |  |
Secure drive flange by means of clamping tool 7012 and unscrew collar nut. |  |
Force out bevel drive pinion or pull off by means of pulling tool 7019. |  |
Remove shaft sealing ring. Check contact surface of shaft sealing ring on drive flange. If contact surface is badly worn, replace drive flange. Note when fitting: Fit bevel drive pinion with new tensioning bush (2). Fasten pulling clamp 6057 to Kukko 22/1 and pull the front bevel roller bearing onto the bevel drive pinion. Important: If the bevel roller bearing is heated in an oil bath, wait until bevel roller bearing has cooled off completely before adjusting bearing and measuring friction. |  |
Using tool 7026, force drive flange on to drive shaft. |  |
Fill shaft sealing ring with grease and fit on so that surface are flush. Fit on drive flange. Adjust bevel drive pinion bearing to the frictional value marsured prior to disassembly, adding 4 cmkp for the new shaft sealing ring. Important: Collar nut (1) must be tightened with a minimum torque of 15.0 mkg (108.45 ft Ib). If this value is not reached or if the frictional value - see example - is exceeded, replaced tensioning bush (2) and repeat measuring process. Example: frictional value prior to disassembly 14 cmkp (1.0122 ft/Ib) new shaft sealing ring + 4 cmkp (0.2892 ft/Ib) ------------------------------------- adjust bevel drive pinion bearing to 18 cmkp (1.3014 ft/Ib) |  |
