Tight layshaft 4'th gear Problem Solved

I, too, am having difficulty with an Andover Norton gear. This is the layshaft 4'th gear. My problem is that the gear will only slide freely onto the layshaft about 1/4 of the required distance. It then binds so that I would need to tap into place with a light plastic hammer, although I have not done so.
What are your opinions on this tight fit? Does this particular gear need to be a free, sliding fit on the layshaft?

Thanks,
Ed

P.S. The old gear is freely sliding and both the layshaft and old gear appear to be in good shape. I am replacing layshaft 4'th since I'm replacing the sleeve gear.

Problem solved. I just heard back from Simon Amos at A/N. He told me that it was normal for this gear to be a tight fit. Encouraged by is email, I used a plastic hammer to tap it fully into place. Surprisingly, after doing so, it now slides on and off freely.

While the gear is a different matter than the bearing...after watching the NOC hemmings gearbox video for giggles, he stated the bearing goes on easy/slip fit. Most of the old ones do go on easier then the later center scribed ones which seem to be 1/2 thou bigger and are snugger AKA press fit in the 17mm bearing.
