Kickstart shaft spindle sleeve 67-3173

What is the function of this part?  What is the annular groove for?
Is it just to keep the spring in the correct position?  Looks to me as it could be left out but I am sure it should not be.

Think you've suss'd it

[KeithJ]

OK but what's the annular grove for?

The groove is not usually there. It looks more like a bearing centre has been fitted.

Too soft for a bearing centre.  Wonder if it was on the original build but no reason to believe this is not original as I've had the bike for years, but who knows?

Both my bikes have the groove

Wilko Johnson / Roger Daltry  "Going back Home" with volume well up is the current groove in the shed (things do keep falling off shelves tho)

Buy it and "Kickstart" you R&B collection (back on subject - did you see how I did that)

Interesting this I have just overhauled my gear box off my 1956 A7 and I also had a spare gearbox so  when I assembled the box I fitted new bearings and bushes and used the best parts from both boxes. Now one box had the part that you have shown but the other box had a longer brass bush fitted in place of that part. I used the brass bush as that is what is shown in my parts list for that year. And yes the other part does have that groove in.

 I am missing this sleeve.

 looking at my kick start quadrant: Instead of a round shaft that this sleeve fits on, I have splines.

 I see the same thing on the draganfly parts page, but the kick start quadrant I have must be for an earlier bike according to them (and no picture available).

 Does anyone know if this quadrant will work for a later swing arm bike (1958) or should I keep rummaging around for the newer style?

 Also, if anyone should happen to have one of these sleeves handy- could you take a measure of the outside diameter and how thick it is? I would really appreciate the help. I can knock one up, but I either need a sample or some measurements.

 Thank you,
Lee

Hi Lee,
The sleeve will fit with some quadrants and not with others 
There are two types of tooth profiles used on BSA quadrants, basically pointed or more rectangular shaped teeth,
Quadrant and ratchet gear must match each other
If my memory works    I will post the size of the collar tomorrow

Hi Again,
Ok, the sleeve measures 1.0in. id, 1.312in od. and 0.375in. wide
This original sleeve fits nicely on two original two piece quadrants, but will not fit on a new one piece quadrant as that measures 1.010in

 Thank you very much john for going to that trouble.

 I will have time to sort one either today or later in the week.

 Its starting to snow here again and they are calling for 4 inches.

 Thats not a lot of snow, but still requires quite a bit of shoveling.

 OK!

 I have a buddy who is going to send me one to copy, as long as I make a spare for him also.

 Looks like a simple enough job, when I get it I will post the measurements here for anyone who ever needs it.

My sample looks quite worn, but here is how it measures out:

Outside diameter:. 1.310

Depth of groove: .013 per side

Inside diameter:. 1.00

Width: .380

Groove width .090

 All in inches.

 I don't think you could go wrong making this .400 wide, this looks quite "ground down" and that's how I will make the new ones.
