The bronze sleeve under the Armature plate is worn and has some slop, possibly affecting timing. Is there a fix for this, or source for a replacement sleeve?

If you find it impossible to locate.................

(Magneto Armature Plate)
(J. Reeves)

If the armature plate has a a loose fitting, wobbling motion (the plate that the points, coils etc are attached to), it is usually caused by a slightly worn support ring. This allows the point setting to change erratically as the armature plate turns.

The cure is to remove the armature plate so that the support which is attached to the powerhead with 4 screws is visible. Then, with a screwdriver and hammer, or some tool of your choosing, and looking straight down at the support ring, make a slight indentation at what would be called the 12, 3, 6, and 9 O'clock positions. Install the armature plate and check for a smooth turning wobble free movement.


You may need to do that procedure a few times to obtain the proper fit (not too tight, not too loose), but it's worth the effort.

Use a small amount of anti corrosive grease between the aluminum ring and the brass support plate and also on the brass bushing of the armature plate when all is well.

Fair enough advice except.....The 9.9 has that support ring with the plastic ring. A problem since day one. To add to that, the OP says his bronze sleeve is worn. I guess the answer is do whatever can be done and hope for the best.

Okay, so that worked. Thank you very much joereeves. Also, I will pick up a new bearing support ring. Thanks for the replies.

FDGator..... I had completely forgot about that much different setup... thanks for the reminder.

RunningLean..... Sorry about the useless advice, disregard reply post #2. Sometimes I get ahead of myself.

Okay, advice disregarded. Now, how do I undo the fix? Don't want to though, cause it worked so well.

Well, if it works for you, that's all that matters. However, I just double-checked my 1976 9.9 book and my cure shouldn't have worked.... completely different parts from what I was speaking of.
