Propeller Shaft Maintenance

Propeller shaft vibration

If the propeller shaft vibrates during high speed,

please first check its radial runout.

1.Support the rear axle up.

2.Turn the propeller shaft, and check one point of the

propeller shaft for its radial runout.

Propeller Shaft

PR-4

Measure point of the propeller shaft (mm):

A=155

B=165

C=185

3.If the radial runout is above the limit value, remove the

connecting flange of one end of the rear axle, and turn
it for 180° then install the propeller shaft.

4.Check the radial runout again, if it still beyond the limit

value, replace the propeller shaft.

5.Road tests.

Appearance check

Check the surface of the propeller shaft for any cracks or pit. If there were, replace the propeller shaft.

Disassembly and assembly

Make marks on the flange disc and remove the

propeller shaft from the end of the rear axle.

Pull the propeller shaft out from the power train, and

plug the protruded part of the power train with plug.

Propeller Shaft

PR-5

Check

Check teh radial runout of the propeller shaft, and if

it is beyond the limit value, replace the propeller shaft.

Check the axial freedom of the spider shaft

If the axial freedom of the spider shaft is beyond the

limit value, you have to replace the spider shaft assembly.

Disassembly

Disassemble the spider shaft. 

1. Make marks on the propeller shaft and flange fork.

2.Remove the snap ring.

PR-6

3.Knock the flange fork with a hammer, and don't dam-

age the holes of the spider shaft and flange fork when
disassembling the spider shaft.

4.Disassemble the spider shaft bearing of the other end in

the same way. Make marks on the dismantled parts,
and you may not change their original position when
reassembling.

Assembly

Spider shaft

1.Install the spider shaft bearing, apply some grease on

the surface of the bearing inside face.

Never miss the needle of the needle bearing when

assembling.

2.Select a snap ring to make the spider shaft among the

required axial clearance and install it. The thickness of
the selected snap ring should  be below 0.06mm.
