Hey guys I’m trying to install 1.5 inch adapter on my 1.5 inch hub on my muscle bike and it will not fit . To small donor dosent come close to wrapping around and the arms that go through the sprockets don’t fit. Any ideas -j0n

I'm having a difficult time trying to figure out what you're saying. 
Hahah we’re both having difficulties today.The adapter and hub are 1.5 inch but it doesn’t fit snuggly around the hub and therefore dosent reach thru the spokes and align with the sprocket.
Norm, I think you got a difficult case here. Where you at geographically j0n?

I live in New Hampshire.the clamshell adapter doesn’t fit around my coaster brake hub. The 3 bolts that hold the sprocket on don’t line up correctly without removing 3 spokes. Iv don’t a bit of grinding and still not Gunna. work. I can take some photos tomorrrow and try to post.. thanks again
I'm guessing you have a 'odd ball' hub?
Please post some pictures of what you've got

Kinda weird the hub has a textured groove on it . At first I tried on a reg bmx coaster brake 1.5 inch hub and dosent fit there either . Those bolts going through the spokes are my issue. I’ll post pictures tonight . Thanks guys
It’s off a 1975 huffy trophy .. I’ll check tonight and get back. Thanks
It’s spokes different then my other bikes.. Bendix 19…1.6 inch with my caliper… maybe I have to respoke the wheel.?
Nice bike!
Thanks for the photos John. Do you have a machineshop that can rebore the sprocket adapter? looking at your photos, I suspect the sprocket mounting bosses will match your drive sprocket and clear the spoke pattern maybe. A 14 spoke flange and a three point sprocket mounting adapter not so good. Wait till Norm chimes back in, he is the pro.

Problem is I already hit the adapter with a bit with a grinder. May have to buy another I just wanna make sure this wheel will work.
My suggestion for making this as easy as possible?? Buy another cheap steel wheel (& another hub adapter if you messed it up too much to use)
Here's one that will work with your 1.5" adapter... BICYCLE REAR WHEEL 20" x 1.75 STEEL 12G HD SPOKES COASTER CRUISER LOWRIDER NEW! | eBay

I have a bunch of bikes and parts.I tried a different wheel still won’t fit. This is different spoke pattern too. 1.5 inch coaster hub
John, you need a spoke count per flange divisible by three. The link Norm posted will get you where you want to be. To save $$$ ask first. That is what a forum is ultimately for. To pick the brains of those that been there and usually got it right.

Oh gotcha. I don’t buy new parts (except chain and tires).I collect and build with only vintage parts of at all possible. Ok hunt out a used wheel spoke count divisible by three is the ticket.. thanks guys.
