New seal did the trick. Spins freely

When I purchased this bike I got list of things previous owner did or had done to motor. (Kinda vague) In 2000 a rebuild. I’m assuming top end. In 2007 crank seals In 2014 countershaft seal From the top end work till now, less than a 1000 miles have been put on bike according to speedo. If I believe...

I pulled seal out,then tightened sprocket on, and now I have “normal to me” rotation. So all of the binding and friction was the seal. Weird...cuz I could hardly spin sprocket by hand with seal in. Bearing looks and feels fine.
I’ll order new seal Monday and see what happens.

Motor has not been apart since I got it. The nut was loose when I put a socket on it to take off old sprocket. I don’t think case bearing is spinning, what I can see with seal in, with no pressure on it. Seal is being stubborn coming out, is there a trick? Should I plan on new seal? Case bearing spi...

Gotcha,
So is it ok that the sprocket kinda binds up when I snug Up nut? Don’t really know how to explain it better via txt.

I’m changing countershaft sprocket. When I snug up nut, sprocket doesn’t spin very freely. It acts like it’s binding up. Parts list shows a “countershaft spacer” part #914608R. Is that spacer behind seal? Or should that slide off with collar.
My bike is a 1972 B+ with a B motor.
Thanks

Thank you,
I decided to order new plunger and spring. Should be here by the end of the week, so I’ll get it back together then. Bike is taking longer then I’d like due to being extremely busy with work. Not complaining, but the bike is more fun then work.

I’m scratching my head trying to assemble shifter mechanism. I think I’m close but... Is there a manual that walks you thru assembly? Mine doesn’t give me much. Or is there someone out there with enough patience to walk me thru it? Ie. Plunger position? Also mine has 3 plunger spring seats. Not sure...

This is how mine look.

Clutch thrust washer outside

I was wondering if missing washer was part of my problem. Missing washer would change overall thickness of clutch pack, right??

I finally have a little time to work on B+ project. I blue printed clutch. I replaced inner and outer springs. My original issue, I wasn’t able to get correct free play. When reassembling, I realized I didn’t have the outside thrush washer. I’m ordering one Monday. Can the clutch function without wa...

Thanks for info, I am a club member so I’ll take a look at blueprinting clutch.

I decided not to do a full restoration on this bike. I’m polishing what’s there, try to make it look as good as it can. But I want a mechanically sound bike, what ever it takes to make it right.

Clutch was acting like it wasn’t engaging all the way, which makes sense with the amount of free play I have. After seeing there were already 3 shims, at .5 each in there, I expected the clutch discs to be totally wore out. I assumed PO was milking the clutch out. So I was surprised and a little con...

So I have add even more shims to get the desired 3/32” free play??

I took clutch apart because I had way too much free play at clutch arm. There were 3 .5 shims, which seemed excessive,? not sure. It has 4 fibers and 3 steels. Fiber plates measure average 2.36-2.40, which is more than new. Book says 2mm new. I didn’t think clutch surfaces was that bad. (Not perfect...

Thank you for info. Pretty primitive technology no?? I assumed it was a bearing of some kind, so I bought new bushings. Obviously not needed.

On this B+ project, when I tighten swing arm bolt, swing arm won’t move. I have To loosen it considerably in order For swing arm to move. Is there a torque spec for bolt?

All the lights worked. Horn did not nor the switch under headlight bucket. I haven’t checked if battery is good yet.

Is this a normal rectifier? It wasn’t hooked up to anything?
What does it actually do?

Thanks for all of your help and support. I was able to tap shifter pin out thru grease fitting hole.

I’m not a big fan of fleabay, But I just bought a manual
off fleabay for Ace 90 with a Ace 100 supplement. I hope that will work for me. You tell me.

I wasn’t sure how much force it took to go out grease fitting hole. I’ll tap it some more.
Thanks, Brian
