DaveO who is the supplier for the #7004 bearing? Or is it just a universal number that I could look up in something like the McMaster catalog.

Here's a subtle hint for the IMWA factory spies that read this forum:

MAKE THE ADAPTER COUPLER PARTS AVAILABLE WITHOUT HAVING TO BUY THE WHOLE $390 FRIGGIN' DENSO ASSEMBLY!!!!!   >:(

Do ya think that was subtle enough?  ;)

DaveO, could you please write your long term experiences with the modified adapter? I'm about to modify mine as well. I've found a pretty cheap KBS type 7004 bearing. I'll put that in instead of the motor-side 6004, as you did. I'm not sure about the greasing modification, but if it works fine for you, I will also do it.
Thanks in advance!

You should go to  sovietsteeds.com  for the answer to your question. I don't think DaveO visits here anymore. He is one of the moderators on sovietsteeds.

You really don't need the 7004 anyway...the 6004 2RS will handle the load just fine...it won't hurt...but it isn't going to help the problem. The 6004's are rated for way better than the rpm's the bearings are turning and are well within the thrust loading of the adapter. The only problem is the grease reaching its temp. limits and the mineral oil running out leaving the solids behind. This quickly dries and things just grind to dust. Either use something like KRYTOX grease (DuPont) or mod. the adapter like DaveO.

Howdy Depner!
My alt. Adapter mod is working well so far. I had to rebuild the top end of my engine recently,(21 Jan.'09) to do the rings and install a Herzog timing gear set, there was NO build up of grease in the timing gear tower. This was one of the things I had been concerned about and could still be a concern if the fitting is over-greased. The 7004 is not sealed and any extra grease pumped in dribbles into the engine from the open bearing end...this seems to be no big deal as there was no grease built up at the bottom of the timing gear tower, or anywhere else IN the engine...

I lube the bearings (2-3 full strokes from a standard grease gun) roughly right before an oil change, every 1000 to 1500 miles or so. Before the oil change, I run about a pint of kerosene in the engine till it gets hot, and then change the oil, the engine was nice and clean inside. There's a pic included from the teardown showing the gear tower interior,only some oil in the bottom, and 1 of the adapter face showing some grease residue exiting the 7004.

Please be aware that when I did this mod I had no knowledge of exotic lubricants such as Krytox, and proceeded accordingly....Using Krytox MAY be a better solution as it involves much less work, I'm not sure how long it hangs around in actual use... It MAY work just fine, I don't know, and haven't heard of any failing. ...Just so you know there may be an easier way.

The other thing is, my mod was done on the 1st version of the adapter, since then, there have been at least 2 other versions of this adapter....so my instructions MAY only be relevant if you have the same version adapter....or not, I don't know because I've only had the one type adapter apart.

Hope that helps you decide your course, and Best Wishes on however you choose to proceed!

Best Regards!
Dave

Nice looking innards there Davie...gooping grease finding its way into the oil sump through the tower was my only concern with your mod.. Looks like it is not a problem. The kerosene bath probably helps.

My KRYTOX adapter is still humming away. I am too lazy to pull it and check it without a reason! No dribbling under the alt. at all...and it is still quiet. Keeping my fingers crossed.
