LN Ceramic bearing

[elgyqc]

Sourcing for the bearing is mentioned in this thread. Also discussion on installing new bearing. I have not completed the installation myself because I was waiting for a flange and am now away on vacation... will get back to it in April.

Good thread. That certainly looks like the stock dual row IMS and is NSK which happens to be the bearing that I removed. I suppose you will just us your internal spring clip/retainer from your old bearing. I was told by the place in Germany that they use two people to install this bearing. One to work two small screw drivers to compress the spring , while the other person slowly taps the bearing in. He mentioned he knew of someone that 3d printed a tool that would compress the spring while installing it. The third option would be to purchase the LN tool that is made for installing this kind of bearing. The third option would require deep pockets as it is not cheap.

I love IMSB discussions!
I plan to reuse the old spring clip. For the installation I was thinking of using a metal collar (that I have already made from a piece of exhaust pipe) held in place by a tie wrap that will hold the spring down and the collar will slide back as the bearing is inserted.
I am also pondering using a "pusher" rather than a hammer to install the bearing. I think a frame could be made that attaches to the block and then permits a threaded rod to slowly push the bearing into place. Doing this would allow one person to do it, pausing the operation to work the clip into place. I am on vacation so have not worked out the details of how this would work.
I made a tool to remove the wheel hubs with a puller rather than a slide hammer when I changed all my wheel bearings. A puller or pusher is much less agressive than a hammer.

I was able to tap the bearing myself while pressing the circlip into the groove but the IMS was out of the engine. I kept the bearing in the freezer overnight and heated up the bore with a heat gun so it required little force.

That's one way to tackle it.

Without the right tool it's almost like needing a second set of hands. If you can come up with a tool to replicate a second person that would do the trick. Or something that works like a ring compressor when installing pistons in an engine.
