I need some info about removing the spindle and back gear on my 9" south bend. I tryed Yahoo but that is more frustrating than helpful.

This has been discussed in the past, so a search of the archives should turn up something.

Basically it's pretty easy, once you work up the nerve to do it.

Loosen the bearing caps, remove the take-up nut on the left-hand end of the spindle, loosen the set screw on the bull gear (I think there's one, it's been a while), put a block of wood across the left-hand end of the spindle, and tap it out with a hammer. The bull gear is a press fit on the spindle shaft, which is what you're tapping loose.

You should probably wait for independent confirmation of this procedure to be sure I haven't left out some critical step.

As you tap out the spindle, the spring-loaded oiling wicks under each bearing will pop up, so keep an eye out for them. The thrust bearing just to the right of the left bearing block will be the first thing to fall off the spindle. Next will come the cone pulley, then the bull gear. Be prepared to catch each of these things in turn!

Installation is basically the reverse. You have to stick stiff wires through the oil cup holes to hold the spring-loaded wicks down while you slide the spindle in, but I think that's the only trick one needs to know about.

The "old guys" at SBL are pretty helpful. You can phone them at 800-245-2843, and their website is:

Do you have the factory manual? If not, I can fax the pages that show the breakdown.

OK the spindle is out, not the prettiest one I've ever saw, but anyway now I need help with the back gear. Do I have to drill out the pin going thru the shaft or what? Thanks for all the help so far. Joe.

It should be a taper pin. Determine which is the smaller end (not the easiest thing to determine...) and knock it out with a pin punch.
