ADJUSTMENT OF TRANSMISSION



SPACER SELECTION FOR ADJUSTMENT OF MAINDRIVE GEAR BEARING AXIAL PLAY



<Measurement using a solder>



  • If soft solder is not available, select the spacer in accordance with Plastigage method.

  • If the spacer appropriate for the standard value cannot be selected using soft solder, select the spacer in accordance with Plastigage method.

1.Install the main drive pinion to the transmission case.

2.Put solders (1.0 mm diameter, about 10 mm long) on the ball bearing at the positions shown in the illustration.
3.Install the clutch housing and tighten the bolts to the specified torque of 35 ± 6 N·m.
4.Remove the clutch housing and remove the solder.
5.If the solders have not crushed, use thicker solders (1.6 mm diameter, about 10 mm long) and repeat steps 2 to 4.

6.Measure the thickness of the crushed solder with a micrometer and select spacers that will provide the standard value.
Spacer thickness: (T1 - 0) to (T1 - 0.1)
T1: The crushed solder thickness mm
Standard value: 0 - 0.1 mm

<Measurement using plastigage>



1.Install the main drive pinion to the transmission case.
2.Installs the adjusting spacer having the minimum thickness.

3.Put plastigage (about 10 mm long) on the ball bearing at the positions shown in the illustration.
4.Install the clutch housing and tighten the bolts to the specified torque of 35 ± 6 N·m.
5.Remove the clutch housing and take out the crushed plastigage.

6.If the plastigages have not crushed, replace the spacer with a thicker one and repeat steps 3 to 5.
7.Measure the width of the crushed Plastigage at its widest part using a scale printed on the plastigage package.
Spacer thickness: (T2 + T3 - 0) to (T2 + T3 - 0.1)
Spacer thickness: (T2 + T3 - 0) to (T2 + T3 - 0.1)
T3: The spacer thickness used for measurement mm
Standard value: 0 - 0.1 mm
