(5) Rear PTO shift mechanism

1.Gear,spur 12 2.Gear spur 14 3. Snap ring(shaft) 4. Ball bearing(6205) 5. Ball bearing(6305)

Note:

- When pushing the R.B.B’s(6305,6205) into the gear ,spur 12,be careful only to push their inner races.

- The snap ring C should be securely seated in the groove and the press-processed side turned towards the outer side.

- Be sure not to mix different pairs of the gear(spur/14).

- Every time a gear is installed,its smooth rotation should be checked.

2.Snap ring

Fig.5-51

Note: The snap ring C should be securely seated in the groove and the press-processed side turned towards the outer side.

1.Stay PTO shift

2.O- ring

Note:

- When installing the O-ring to rear transmission case,take care not to damage it or allow to fall.

Note: a.Apply oil to the drive pinion and related parts ahead of time.Then install them and tighten the assembly to the specified torque. b.Be sure that the starting torque of the drive pinion meets the specified level. Starting torque is 8-11 Kgf.m (0.08-0.11KN.cm) c.After the starting torque has been adjusted to the specified level,crimp the lock of the nut at one point as illustrated. d. Be sure that these parts should turn smoothly

When the drive pinion or the ring gear has been replaced, the proper number of shims to be installed should be determined based upon the following procedure:

1.Gear range(13X20X29T)

2.Ball bearing(6207)

3.Needle bearing

4.Gear spur(30X35T)

5.Washer(25X46X07)

6. Ball bearing(6305)

Note:

1.Apply grease when installing Needle bearing

2.pay attention to the installed direction of gear(spur/30-35)

3.After installation,be sure to slide smoothly

8.Differential gears.

Note:

1.When assembling without replacing the pinion gear and ring gear with new ones,provide the same shimming thickness as that provided before disassembly.

2.Backlash between dif-pinion and dif-side gear should be within as range of 0.1 to 0.2mm (0.004-0.008 in) and these parts should turn smoothly.

3.When reassembling the used pinion and ring gear,reinstall the same thickness of shims as was installed before disassembly in each shimming position.

4.Backlash adjustment between the drive pinion and the ring pair(Fig5-8) i.As the drive pinion and the ring gear make a pair,be sure not to mate them with other parts from differential tractors.

5.Adjust the shimming to backlash of 0.1-0.2 mm (0.004-0.008 in). The standard shimming is 0.4mm (0.016 in) on both sides.
