Bought an AM inner retainer in Feb., '00 that was made, at least, too tall. The new standard rollers (measure .250" thick) will fit into the cage, but as as a "bearing assembly", it will not drop into the bottom recess of the left-side hub. The rollers have to be loaded individually into the installed cage, and once there, are impossible to turn with your fingers wedged in there. Then, when you install the bearing retaining washer (covers the exposed ends of the rollers in the cage) the washer covers up the lower snap-ring groove.
The old rollers are a little pitted on at least one end and measure .248" thick. The new (standard size) rollers measure .250" thick. So, the side of the rollers wore .002" in thirty years. The old rollers racked loose in the old retainer. The old rollers are .525" high. The new rollers measure .573. That's a height difference of .048", and... "they wear on the ends too. That's what their suppose to do. Some people just take the oversize bearings and put them in the old retainers", so said Kick-Start Chuck. I also bought the AM (small) (star cover side) bearing retainer in '00. It has the too-thick-looking base, same thick base as the (bogus) large, inner retainer has, but I haven't tried to fit the small retainer into the star side of the hub yet.
I have a set of .0004" oversize rollers on hand (an act of God, or "them" knowing what i needed, better than I did, because I had ordered .0002" o.s rollers and they sent me .0004" o.s.) that I put into the old cage and the rollers were a nice slide-fit, and lowered into the left hub as one assembly. The old retainer is pretty thin at the base, so I am waiting on new AM retainers Chuck says his customers rave-on about, which I purchased to compare. He also has n.o.s. OE retainers, but my last name is Perry, not "Rothschild". If his retainer bases are not much thicker than the old ones I have, then I may go with my .004" oversize rollers in my old retainers.
Question is: How do I measure what the '59 H-D service manual says as "select roller size that will give .001" to .0015" clearance". Where and how is this measurement taken? With rollers installed in the cage and using a plunger dial indicator/w/ stand? Or, with a feeler guage between the roller and inside surface of the hub once the cage and rollers are installed?
The answer is: You have to measure the bore of the hub with a inside "T" guage and a math formula to calculate a "running fit" and I need to work it out on the phone and fax with Stett.
Try an rebuild a hub following the H-D manual, but don't follow the diagram on page 2C-3. Not drawn exactly as a true in-line assembly. The washer/retainer that goes on the extreme left end of the hub under the top snap-ring has a stepped side that should be pointed outward and in the place of where they have flat "#15. Retaining Washer." And don't e-ven try to rebuild a hub following the Clymer manual. They call something one thing in print and the same thing something else in a diagram and you have to clothspin several pages together and flip the paper collection back and forth. We'll have it laid out differently in our next book, and the "roller fit formula" illustrated in photos or my name isn't Kirkland.
