While doing the trans work, I noticed some things about the 4.764 bearing vs the 5.062 bearing. I ended up messing up the 5.062 bearing b/c I dropped it in without putting the oil guide in first, and then I was unable to get it out via heating the case. The slide hammer & puller ended up jacking up the plastic part.



left = 4.764 bearing from ep3, right = 5.062 bearing from JDM CR-V

The snout diameter of both countershafts is 1.376", so the bearings are interchangeable.

The first thing you'll notice (besides the piece of plastic missing from the bearing on the right) is that the 4.764 bearing has more numerous but smaller rollers. 11 rollers vs. 10 rollers. I measured the outer race size of both bearings, 2.672" diameter x .781" thick. However, differences appeared when I measured the length of the rollers. 0.5191" vs 0.5111" long, 4.764 vs 5.062 respectively. So the the rollers on the 4.764 bearing are ever so slightly longer. Not a functional difference IMO.

Being that the cost of the two bearings is pretty much the same, with the 4.764 bearing being slightly more expensive, I'm going to use that one since having 11 points of contact around the countershaft should be better than having 10.
