I'm starting I think that's why most DIY's tend to go early, with most owners just pressing the bearing in until it's stopped against the bores edge. While HD's tool probably has a depth gauge.
In fact - that's probably why there were so many early failures. HD had to find "optimal" placement of the bearing. Especially considering all the manufacturing stack-up variances. So bottom line - if you're a DIY'er it's absolutely mandatory to get the specs right. Whatever they are? And, if you have someone do it, make sure they know what they're doing! Of course - just a guess.....
I think your assessment makes sense. The instruction sheet gives no specs, but just says to use the tool. Now, how much does the tool cost?
