WHERE is the pivot bolt on a 1993 Sentra PS pump?

One more plea about the drive belts.

I thought I'd save some money buying and replacing three engine belts myself -- AC, PS/WP, and Alternator. The job turned out to be a lot harder than I imagined.

Day 1. (Afternoon, actually; it's really hot out there.) The outermost belt (the A/C) gave up quickly once I figured out the idler pulley, but the alternator wouldn't budge along its slotted track until it was almost dark. That's when I found the alternator's pivot bolt. Aha, the Pivot bolt!! It pivotted and there was slack, behold! But that belt is blocked by the PS belt. And now it's dark. Shit.

Day 2. What keeps me from changing the PS/Water Pump belt is the PS pump won't budge. I found and loosened its lock nut, but the adjusting bolt does nothing. Guess it didn't read the manual. So, I'm guessing it's a pivot bolt issue again, but *where is it*??

What I loosened on the front side was probably the adjuster bracket bolt (can't see nuthin). If the PS pump pivot bolt is the 14mm on the *back* of the PS pump, my puny 6" Craftsman ratchet wrench is no match for it, and that's all I can get in there. Any ideas??

So you can see I'm not much of a mechanic, but I tried. After putting my '93 Sentra XE on the jackstands three times, I called the Goodyear place. The tech said they're not that crazy about installing parts (belts, in this case) brought in by a customer, but WTH, they'll do it for $71.

This isn't spare cash, it's rare cash, and I can think of things I'd rather spend it on. $71 to change two belts. >:

Thanks for your attention, Jm

As far as finding the bolt, use good light and/or feel around. This thread might help.

You might register there. The forums are nearly always better than a newsgroup for this kind of thing, because you go directly to people who work exclusively on these cars. You have to decide whether or not to pay 10 bucks for the right wrench for the job and a flashlight, or the 71 bucks for somebody else to do it. For 71 bucks you could get a good wrench set that includes open end/box end wrenches plus the socket set. Besides, you might put a pipe on the ratchet handle. Seems silly to give up so easily after getting halfway there. Don't give up.

Just a few of the many things I'd prefer spending the money on. :)

Thanks for your encouragement. I see that the PS pump pivot has bothered other people, too. Here's something I found after following your link.

Post #6 in the thread gave me the bad news: Yes, I had found the problem bolt, and yes, it's gonna be a b!+@h.

OK so now you know how the belt gets tightened on the alternator.

PS pump has three items you need to loosen up to adjust it. One is the bolt going through the bracket towards the top. The next is a LOCKING bolt that LOCKS the adjuster bolt in place. That bolt will NOT move if you don't loosen the lock first. The last is the adjuster bolt itself.

For those two look DOWN from the top of the pump. Toward the outside of the pump itself you should see a bolt head that looks like it screws into the bracket from the side. That is the adjuster bolt. Now if you look at that bolt and follow it down to the bracket you will find another bolt that goes into the threaded block from the front of the pump and tightens down. It is the lock bolt. you just loosen that bolt and put a bit of oil on the adjuster and it should move enough to loosen the belt.

Oh and the AC idler pulley also has an adjuster with double nuts that lock it in place.

Want a picture of this mess? just remove NOT from the address.
