Put matching marks on propeller shaft flange yoke and transfer companion flange.

CAUTION:

For matching mark, use paint. Never damage propeller shaft flange yoke and transfer companion flange.

Put matching marks on propeller shaft flange yoke and final drive companion flange.

CAUTION:

For matching mark, use paint. Never damage propeller shaft flange yoke and final drive companion flange.

Remove propeller shaft assembly fixing bolts and nuts, and separate propeller shaft assembly from transfer companion flange and final drive companion flange.

Remove propeller shaft assembly.

Remove heat shield plate.

Perform inspection after removal. Refer to Inspection.

INSTALLATION

Note the following, and install in the reverse order of removal.

• For non-reusable parts, refer to Exploded View.

• For each tightening torque, refer to Exploded View.

• Align matching marks to install propeller shaft flange yoke and final drive companion flange.

  

• Align matching marks to install propeller shaft flange yoke and transfer companion flange.

  

• If propeller shaft or final drive has been replaced, connect them as follows:

  • Install propeller shaft while aligning matching mark of propeller shaft with matching mark of final drive on the joint as close as possible.

    

    NOTE:

    Matching mark is has been painted in either position.

• Perform inspection after installation. Refer to Inspection.

Disassembly and Assembly

DISASSEMBLY

Put a matching mark between propeller shaft and flange yoke and remove snap rings .

CAUTION:

For matching mark, use paint. Never damage the surface.

Lightly tap bottom of yoke using a copper hammer and remove journal bearing.

CAUTION:

Never damage the yoke.

ASSEMBLY

Install journal bearing to journal.

CAUTION:

• Never reuse journal or journal bearing.

• Always replace journal, journal bearing, and snap rings as a set.

• Apply multi-purpose grease to journal bearing.

• Install bearing using a vise.

  

  CAUTION:

  Never damage bearing or flange yoke.

• Install journal to propeller shaft so that grease nipple on journal portion is in the same direction.

  

  CAUTION:

  Never reuse journal.

Measure journal axial play. If necessary, select the appropriate snap ring.While pushing to 98 N·m (10 kg-m, 72 ft-lb), check the clearance between snap ring and flange yoke .

Journal axial play

: Refer to Journal.

If journal axial play is outside the specification, use a thicker/thinner snap ring to adjust.

CAUTION:

• Never reuse snap ring.

• Select snap rings with a difference in thickness at both sides within 0.06 mm (0.0024 in). For selecting snap ring, refer to the latest parts information.

Install selected snap ring as shown in the figure.

Check that the journal moves smoothly and is below the joint flex torque specification.

Joint flex torque

: Refer to Journal.

NOTE:

The joint flex torque may not be satisfied soon after the assembly.

Check the journal axial play. Refer to Inspection.

Inspection

INSPECTION AFTER REMOVAL

Appearance

Check propeller shaft tube surface for dents or cracks. If malfunction is detected, replace propeller shaft assembly.

Propeller Shaft Runout

Check propeller shaft runout at several points with a dial indicator. If runout exceeds specifications, replace propeller shaft assembly.

Propeller shaft runout

: Refer to Propeller Shaft Tube.

• Propeller shaft runout measuring point (Point “ ”).

  

  : Front side

  Dimension
  A	: 80 – 100 mm (3.15 – 3.94 in)
  B	: 100 – 120 mm (3.94 – 4.72 in)
  C	: 268.5 mm (10.57 in)

Journal Axial Play

As shown in the figure, while fixing yoke on one side, check axial play of joint. If the journal axial play exceeds the specification, repair or replace the journal parts.

Journal axial play

: Refer to Journal.

Joint Flex Torque

Check that the journal moves smoothly and is below the joint flex torque specification. If the joint flex torque exceeds the specification, repair or replace the journal parts.

Joint flex torque

: Refer to Journal.

INSPECTION AFTER INSTALLATION

After assembly, perform a driving test to check propeller shaft vibration. If vibration occurred, separate propeller shaft from final drive. Reinstall companion flange by changing the phase between companion flange and propeller shaft by the one bolt hole at a time. Then perform driving test and check propeller shaft vibration again at each point.
