The p11a rear wheel

could someone please measure the distance from the outside of the speedo drive and the flange on the swing arm where the axle fits through. Thanks.

Mine is probably incorrect. The spacers and other pieces on my axle may be different since it is a '67 P11, and was not together when I picked it up in boxes. I came up with spacing that works, but it took a few tries. Anywho it's 1.75" on my P11 and made up of spacers, washers, and the speedo.

(Made a big mistake on where the measurement was taken from and here is the Edit I measured from the outside face of the Lock ring (part number 2 shown in post #19) and the inside face of the swing arm axle flange. I also have the hub cover on the spedo side, so that measurement would be greater without it. If you want some other measurement, you'll have to figure out how to describe it better. Also note that my P11 is not a P11A if that makes any significant difference at that location.

Ron L should have an accurate measurement if mine does not make sense on your P11A.

The spacing from the outside face of the speedo drive and the speedo internals is the one you have to get right or you or your customer might lock up the rear wheel when least expected.

There is only the spindle distance piece (P/N 03-3083) that fits into the swingarm slot and abuts to the speedo locating bush (P/N 02-8073).

I measured the distance to between the nut on the locating bush and the inside of the swingarm as 1/2 inch.

The measurement is critical so I can determine where the sprocket is located. Then I can move the motor/trans unit as a pair and line up the gb sprocket to the rear wheel sprocket. I certainly won't rely on the factory spacers to fit perfectly. The speedo drive that came with the bike is crushed and flopping in two parts. I don't think I have the threaded axle piece shown in the picture above.

If you are determining sprocket location, I would think you would start on the other side of the wheel. Proper spacers between the brake drum/sprocket and the swingarm should get you the alignment. Or mount the engine/gearbox with the correct factory spacers. Are you building something special? Why are the factory spacers not 'perfect' enough?

Do you have the measurement for the sprocket location? frame to sprocket. I am building a stock P11 but I was given a flopping rear wheel with partial spacers. All I need to do is get the motor/trans lined up correctly then the fine details are up to the new owner...with full disclosure.

At last. a really useful set of pictures describing the speedo side of the rear spindle.

So that's where those parts are supposed to go. Thanks much Ron for that last image and the useful clarification. I always tell people to ask you if they need accurate info about the P11.

I ended up cutting the threads off the part with the threads (that I bought new last year) and using it for a spacer somewhere else entirely. I couldn't make sense of how it worked or where it actually went not having a complete bike or any useful documentation for the P11.

I don't have that nut on the outside of the speedo housing that locks the speedo locking bush in place. Not sure it would have helped though. I still might not have been able to figure out where it went if I did have it. My speedo is locked in place with tension on spacers only. Very dangerous all things considered for how many miles I've put on that thing on the street.

Time for me to buy those parts and do something right for a change.

This is what my speedo side looks like.

The engine and gearbox spacers are a non-intuitive exercise without the information I provided previously that came with the spacer kit. I did it without the spacer location information in 1973 and made a few spacers. The engine was a little offset right at the front. It didn't make much difference for several thousand miles. However, I have corrected it in my golden years with the correct parts for a stock P11, and it all lines up for the engine and AMC clutch and gearbox parts. When I install the TTi 5-speed gearbox hopefully next month I may have to make a change to a few things with the gearbox mounting. Nothing a guy with a drill press, a file, a hacksaw, and 60 years of experience screwing things up can't handle.

excellent picture. Can you please measure the distance between the speedo drive and the swingarm......the thickness of the two spacers in the picture.
In #22 that distance looks like a lot more than 1/2 inch.

It is more than 1/2" on "my" P11, but I am using slightly different parts. The distance from the outside face of the speedo drive to the inside face of the swingarm axle flange is .75" or 3/4".

By the way, there are actually 2 wide spacers and a large flat washer up against the speedo face.

I'm just confusing people more than likely. Ask Ron what goes where on a proper restoration.

I found the speedo bushing...it is battered, the threads and nut are demolished. The speedo drive has no internal bushing and the speedo drive is crushed and in 3 parts. I had to pound the speedo drive bushing off the axle with a long drift.
Off to the hardware store tomorrow to find a series of 5/8" I.D. shims and washers. I mickey moused it to find the proper position and I believe it is
do-able at least to get the motor and trans lined up. Thanks, all, for the pictures.
