Sprocket Installation Problem

manyguns · #1 04-20-2009, 02:43 PM

I've run into a problem installing the sprocket on the rear hub. The center hole of the sprocket is 1 3/8" diameter, but the hub that it has to fit over is 2" diameter. How am I going to enlarge that center hole in the sprocket so it will fit on the hub? Anyone run into this problem? Do I have to get a different sprocket? I got my kit from DAX.
Thanks, Tom

you will have to enlarge the hole. i did it with a die grinder, be very carefull and try to keep it as round as possible, frank

That's an awful lot to enlarge with a die grinder, isn't it?

yes it is ,you could take it to a machine shop if ya got the bucks or get a different wheel. all the sprockets i have seen are about the same size. maybe someone else can help more. look at all the sites here or maybe email dax he knows alot. frank

did you take the dustcap off your wheel hub?then check the size.

mark a 2" circle on the sprocket,centered
i would use a drill with metal bit and drill holes in a circle until the middle piece comes out.
then use a dremal to get the middle piece out.

Yes, I did. The hub itself is 2". I might try that.

If you are not an a big hurry you can send it to me. I will bore it any size you want for free. All it would cost you is the shipping. Or I can bore one that I have and ship it to you for just the price of the sprocket and shipping.

That's very nice of you. Let me check it out again tomorrow and I'll get back to you.
Thanks, Tom

I wish I came across this earlier......I would have sent you mine to do!

The way I did this was I first found something close to the size of the hub. Then after drawing it on the sprocket, I used one of those powered jigsaws and cut notches to my line, all the way around my drawn circle. Then I pried out a couple of pieces and went ahead and cut the circle out with the jigsaw. It was then that I used the die grinder and it came out really well.
