Loose Sprocket

newbie555 · 12-19-2007, 05:16 PM

So I put a new rear sprocket on a few months ago and when i did it one of the nuts on the stud got stuck and now if i try and tighten it or loosen it it just spins the stud. It has now loosened up the sprocket pretty good. Can i just drill and tap through the sprocket and hub and but a bolt in it? Do i need a whole new wheel. If i do does anyone have a rear 18" drum brake setup for sale. Thanks

You'll need to remove the big circlip then remove the sprocket along with the studs. Put the loose stud in a vice and remove the nut. Rethread it if possible and put on a new nut. If the threads are too buggered up you'll need a new stud. Not a good idea to bolt the sprocket to the hub because you won't have any rubber dampers.

The stud spins almost freely. How would i be able to take it out

The studs are not attached to the hub, they just fit into a hole in a bushing. Leave the nuts in place then remove the big circlip and the sprocket will pull out along with all 4 studs.

A piece of advice, sod the expense and use genuine Honda ones. The Chinese pins seem to be poor quality and WILL shear. All XL,CB and CD models between 125 and 175cc use the same pins.

Its a newstar DB-200. Anyone got an idea of what new studs would cost?

Unless whatever you buy is an upgrad in quality I wouldn't spend the money. I mentioned this before in another thread but my Dad made some out of grade 8 bolts. We replaced both sets on our bikes. He mentioned he'd make more for $80 a set, if your interested.

I looked on bikebandit and I can get ones for an xl175 for $4 each. I think I'll get some of these.

fatboy250 · 12-21-2007, 03:27 PM

Sounds good man.....let me/us know what quality these are and if they are a definite upgrade. Also, when you do finally know for sure that everything matches please post it in the parts section.

Thanks,
Jason

All right heres an update. I pulled my hub wheel off and pulled the sprocket off the hub. The rubber gromets that are inside the holes where the studs go in are completely torn apart.

heres the hub

heres a closeup of the grommet

look at how much space is there

Do you think I can just stuff some rubber in there? Does anyone have any of these grommets?
