Tub Faucet Repair

I have a newer home, built in 98, with one piece tub/shower units, the tub has a single handled delta faucet that can be turned 180 degrees to turn on the water. well, the tub is not regularly used, and the faucet it leaking now. I took the handle off, and the little guide that limits how far you can turn the faucet. Once the brass guide (or what ever it is called) is off, you can spin the handle around 360 degree's continually. I spun it all the way around hoping that it would stop the dripping / running faucet. with no luck.
With the guide off I can adjust the handle to a point that has the water dripping about 1 drop per second, (that's the best is does) but, the valve is in a position that would prevent me from putting the guide back on, I'm guessing that a washer of some type is damaged or worn out inside the assembly, How do you get inside one of those faucets? it does not seems like I can service it as it is all closed, or so it appears. Is it possible to replace a seal inside the tap, and can I do it without wrecking the tub unit?

ooop,
Found my faucet at delta's site, http://deltacom.deltafaucet.com/media/Product_Tech_Docs/Maint_Installation/25001to50000/39567_v1_4689.pdf this looks like it should cover everything I need, any tips, to consider? looks like I've got it all figured out though.

When you go to the hardware store to get the parts don't forget some plumbers grease. The little tube of the stuff is probably a lifetime supply, but it is worth it.
Also with the water off feel around inside the valve body for any rough spots caused by calcium build up. If you got some, soak a paper towel in vinegar and stuff in in the cavity for a while to soften it or dissolve it. This is what usually eats the rubber seals. The plumbers grease helps the calcium from sticking.

Roger, just wanted to say thanks for that little tip about the vinegar, it worked great, there was some build up on the internal parts due to lack of use and the vinegar cleaned it all up nice. works great again, thanks

With the (Main) water supply turned Off, turn the (Delta) bath faucet ON. Then open other faucets at a lower level in the house to drain off water in the pipes. That will help avoid nasty surprises when you disassemble the Delta control, like water dripping down into the wall...

Thanks, I didn't think about that, I'll make sure to cut the water AND kill the pressure before pulling the delta faucet all apart, One thing I did notice, and was surprised about, is when I took off the cover plate for the faucet, there was a breeze blowing into the tub thru the opening in the shower wall. The faucet is on a an interior wall, is this normal? I have a crawl space where all the pluming is run, and I'm guessing at the air entering from the crawlspace into the wall where the pipes pass thru the floor, or where the vent pipe leaves the top of the wall. (single story)

I have one of these valves in my bathroom too. Mine has the 2 shutoff valves (turned on/off with a screwdriver) that makes it very convenient to shut off the water supply within the valve body before it enters the main knob/handle operated valve. By shutting these off, you don't have to worry about all the water in the pipes feeding the tub valve to drain out the valve chamber when you remove the large cap. Mine is from 1987 and has the usual Delta springs and rubber seats as wear items. Some (newer ones?) have an expensive plastic cartridge that needs to be replaced. when the valve drips when shut.
