Hi micron16,

Thank you for the donation.

There are no diagrams availble to show yo so will have to depend on explanation and hope it is clear for you.

Before removal of propeller shaft, mark their original installed position for reference of installation.

After removal of shaft assy, mark the shaft and flange position. Installation of flange should according to original position. Twisting the flange might cause imbalance after installation.

1. Remove the locking clips of joint caps. If clips are external, a circlip plier would be required. Internal clips can be removed with the aid of a screwdiever to hold one end and the other end punched out with the aid of a screwdriver and hammer.

2. Spray some WD-40 to the joint caps area, both inside and outer part of flange.

3. Use a bar and hammer to knock one end of the U joint cap in. The other end would come out. DO NOT over shoot. Reverse the procedure to knock the 2nd cap ( the one pushed out) in and get the 1st cap out as far as possible witouht overshooting.

4. Use a mallet to tap the outer flange/shaft to vibrate the cap out. Once both caps are out, you can remove the flange. Repeat with the other 2 caps. Take care not to use excessive force to avoid damaging cap holes.

5. After removing, reinstall 2 pieces of bearing cap to cross and compare the size with the new joints. There are different sizes available, this is to ensure you got the correct part. Measure the outer diameter and length of joint with cap if possible.

6. When reinstalling, take care not to allow the needle bearings in the new cap to come loose or fall out.

7. Remove the caps from the new joint. Note the grease nipple position for the caps during installation. Get them in line with the front for easier greasing during maintenencce service.

8. Carefully put the cross into position and install 1 cap, start with shaft side. Slowly push the cap in without allowing the cross to come loose. While holding the cross to prevent it from detaching from the cap, knock in cap as far as possible without overshooting into the center. Installl 2nd cap and knock it in. When caps are secured, the would not have any free between the cak and cross. Install the clip for the first cap installed. Knock the 2nd cap as far in as possible, do not use excessive force. The ccap should now have sufficient space to install the 2nd clip.

9. Repeat with the other flange.

10. After installation, hold the flange and use mallet to tap at the outer area of the flange to get the caps to seat correctly.

Hope the above is clear enough for you to understand.
