In cleaning up my storage area I found I have another Fox 35, 50th Anniversary edition,  that I do not need.    I don't seem to have the original box for it so it will be shipped in an old 40th Anniversary box with a Fox muffler.   The engine has a Fox NVA in it and I found a prop nut that fits a Fox 35 that I will include also.  The prop nut seems to look good on a military type model.   I believe the  engine may have 20 to 25 flights on it.  It turns over nicely with excellent compression.      $75.00 will include shipping to lower 48 states.

I change mine with any perceptible change. The EFlite bearings I use get changed out pretty regularly.

I've built about half the kits I have owned.

Hey Brother Randy!  Wonderful to hear from you!!  Your caption says it well, a VERY long time.  I've missed ya.
Sorry to learn of your problems, but now maybe I can whup you.(?)  Okay, probably not.
I was blessed to be able to find a hole in the fence at age 60, drew on my 401K for two years, then hit the SS.  I did the math, and I've made more from them by taking it early than if I had waited.  My (advanced) age had everything to do with it.  Getting out in 2000 verses now was a distinct advantage monetarily, at least for me.
Wish I could be up there with you when you start working on the two handed method, might be a way I could help.
So...you take good care of you, the wife, and three daughters - that's the main thing right now.  God's best to you, my friend,
Will

I would say if it's perceivable without equipment, it's time to change the bearings.

He knows more than I do about this.  BTW.

Does anyone know of a good source for a snap ring pliers?

Not specifically, but Amazon, Wholesale Tools, MSC, Eastwood, and a whole raft of other suppliers should have them.  The real question (which I can't answer) is who makes the best pliers -- once you know that there's probably a dozen places to get them.

I just felt the shaft in a brand new motor.  It has 0 play.  A how-too change bearings video is at:

 

I think the Cobra motor has a snap ring that needs to be removed in order to pull it apart.  A pain to say the least.  Does anyone know of a good source for a snap ring pliers?

Does the motor run OK?  Does the prop angle change significantly when you wiggle it that way?  Can you feel a gravelly feeling when you turn the motor, or is it smooth aside from the normal cogging?  Does the spinny* part of the motor rub on the stay-put part of the motor when you're pushing and pulling it while turning it?  Or is it just a side to side translation of the prop?

I suspect that a certain amount of wear-in is normal.  Ball bearings in general offer you a choice between high friction with good locating, or low friction and a bit sloppy.  So you actually don't want the tightest fit in a motor.  "Noticeable play" is hard to quantify, though, because there's slobs out there that would only notice play in the bearings when the motor fell apart, and there's uptight detail-oriented guys who might notice a few thousands of an inch of play that no one else could perceive.

On the plus side, I'm pretty sure that changing out the bearings in these motors is fairly easy -- just get a set from Boca or Cobra, press out the old ones, and press in the new.
