bearing tolerance

L Leonard All Messages By This Member #5039 All I've left to do on my Lot? 4 is tend to the spindle bearings. If I tighten the caps the spindle turns with? a? lot of drag. I was wondering if there is a recommended torque for the caps and if Bert used shims in his original designs. I can find these by trial and error but I thought I'd ask to save a bit of time. Be well Larry
glenn brooks All Messages By This Member #5040 开云体育 Larry, I have the same problem with my Dalton. I believe it is due to wear in the bearings. Over the years they have become out of round, hence when you tighten them a bit to much, some high spots grab the spindle and start to restrict movement. ?I scrapped my bearings into better shape a few years ago and improved their action. Still not perfect, but much more effective now. The best way I have found to to tighten the bolts in the caps is to put a bar into the spindle, and pull upwards against the bearings. Adjust the shims and tighten until you achieve the .002” limit of movement. ? Also I believe equalizing the shim height on both sides of the caps is important.

L Leonard All Messages By This Member #5041 I was hoping I wouldn't have to scrape.. Oh, well, it's off to the store to get some hi-spot blue. I'll start off with a .01 shim and peel it back one at a time to get the clearance I need. I still have some plasti-gage from my motorhead days.

glenn brooks All Messages By This Member #5042 开云体育 Larry, You may ?find some pre existing shims under the bearings. ?I found a nice package of brass shim stock on line for under $25 a few years ago. Gave me a nice range of 6x12” shim stock sheets from .001” up to .025”. ?I much prefer to cut and stack shims strips rather than use the peel off type. ?More flexibility in arranging desired ?thickness, I think. ?But, thats just personal preference. Yellow metal scrapes pretty easily. I just used a mild steel 4” straight edge boat knife from my old commercial fishing days. Slow and steady does the trick...

L Leonard All Messages By This Member #5043 Good news , I think. Motor wired, installed and running.? Should have paid more attention in Juice 2 in college. More than reasonable rpms on jack shaft.? Belt runs true.? I do believe the old girl smiled when I started her up.? Next is the bearings. I wonder, since babbit is basically solder, if I can build up the low spots with some 60/40.? More research is needed. A winter project I think. Be well Larry On Sunday, September 13, 2020, 1:12:29 PM EDT, glenn brooks <brooks.glenn@...> wrote: Larry, I have the same problem with my Dalton.
