Pulley and Belt issues w/ alternator, power steering, and crankshaft

First post - thanks for the help.

Broke down yesterday with what seemed like a dead battery or perhaps a bad alternator. Towed it to a close mechanic (not a LR or RR specialist) and they pointed out a few problems. They noticed that the alternator belt had fallen or broken off and was no longer there. The power steering pulley does not have any grooves, and the belt that goes around it have 4 grooves. They seemed to think this was an issue and is why the belt was falling off. I actually don't think this is an issue since I have a parts 1991 RRC and it also has a smooth power steering pulley. Do you think this is an issue? However, I also noticed two other things. First, the alternator has the wrong number of grooves! This to me threw up big flags. The alternator has 6 grooves instead of 4 like the crankshaft has. Second, if you were looking at the vehicle aerially, the pulleys for the crankshaft and power steering line up, but the alternator is way off. I literally bought this car a week ago, and the mechanic was talking about an engine rebuild (praying that isn't necessary). I have another alternator off my aforementioned parts car. Should I just install this other alternator that seemed to be working on my parts car? If I do that, how do I make the belt tight, since it seems like the system of brackets that hold the top bolt for the alternator in place has been altered, and probably wont fit a new alternator tightly? Thank you so much for your help.

Re: Pulley and Belt issues w/ alternator, power steering, and crankshaft

what year model? Are you talking about a serpentine belt?

RNC003.jpg This is a 1994. No it is not a serpentine belt. Like I said it is the belt connecting the crankshaft, power steering, and alternator. This is a picture of the engine with the belt highlighted.

Re: Pulley and Belt issues w/ alternator, power steering, and crankshaft

Mine is a 1990 with all v pulleys and belts. T he alternator runs a separate belt off the power steering pump, so if someone had installed an earlier alternator to your car this might be why its not lining up, as your diagram shows one belt for the power steering and alternator. It sounds like you run three flat belts with four grooves. If an earlier alternator has been fitted, the v pulley might have been replaced with whatever was handy.
On my parts car and on my car, the alternator mounting has been butchered to fit an after market alternator, although the one on my car has an sliding adjustment bracket. You might be in the same boat. Sorry I can't be more help.
