I have the first rear axle out, and I'm down to getting the inner bearing, washer and bearing collar off.
However, the seal that is on currently is marked SKF/CR18657 and that is very different in dimensions to that quoted in the "wotsitoff" section. It may be that list is simply wrong and I've purchased the wrong thing ahead of time. Given that this is a modern seal it's been changed at least once in the car's life, but also the inner bearing collar is clearly steel and doesn't look to be the same material as that in Gary's thread https://peerless-gt.activeboard.com/t65156517/de-dion-inner-bearing-collars-new/
Does anyone recall the code for the inner bearing seal when they changed it? I'm wondering if the inner bearing collar is not original and a different dimensions or something.
From my limited experience I'd suspect that it's been changed at some time in the past Dave. I had my DeDion rebuilt by my local engineering shop a couple of years ago. I had been searching for a bearing supplier using the codes off the wotsitoff page and was surprised to find one about 20 miles away.
I gave the DeDion, bearing codes and address of the supplier to the engineering shop and they carried out the job with no comment on any differences between the info I supplied and what was actually done.
