    Thank you on the details of greasing. I will get bearing greased at a garage with a grease gun. My main issue remains of oil leaking from the knee.The leak earlier was due to hardening of the o rings at the cap and filter screw. Not due to damage with water as I have thought.About 8 weeks ago I topped up the oil but it leaked out again. The Teflon tape I used to fasten on the screw heads did not help to make a perfect seal. I just obtained the right o rings and topped up the oil again. Unfortunately, the oil leaked again. This time I observed the oil came out of a breather hole on top of the knee.

In your photo in step 11, I also see a hole at the top of knee. This hole is made by design. Not sure of its functionality.Any pointers how to stop the oil leak from the top of the knee?Looking forward for some advice. Thank you.

  • Prosthetic Knee Oil Change

    Thank you for the pointers, much appreciated. I will find out where exactly the oil is leaking before proceeding. I think, using powder is a great idea to pinpoint the leak. I dont have knowledge about Silicon Oil CST. I will buy 30ml-60ml 150CST silicon oil.The oil leak started after the knee got soaked with water about 15months ago. Then I sprayed silicon WD40 on the knee bearings. Not sure if that could have contributed to the problem.

  • Prosthetic Knee Oil Change

    I wish to change the oil of my Ossur total knee 2100 which is about 5 years old. Some oil has leaked out of the knee over time. The knee is still functional thou. Advised to change the entire knee by the experts as they are not able to service it. I am in the process of getting the tools and oil. I will try the to use the 450cSt Silicon oil as suggested/What quantity of 450cSt Silicon oil will be enough for the replacement?
