The bearing can be replaced if needed. They press in and, by crossing the number, they're usually not too hard to find. They all use more or less standard bearings that are used on all sorts of things, not just idler pulleys.

That ebay one does look like a double but you can find new pulleys anyway. It's the bracketry that's rare. That looks like what you want ply478

I suspect the "bracket" (not the idler or pulley) is different between the RV2 and C-171 Compressors. The '85 would use the C-171 Compressor.

I think the OP is looking for one for the RV2, maybe? Looking at the part in the above link, it Might not matter

That ebay one looks like it should work. 2 bolts top of 2water pump and one for the alternator mount?

BudW The #334 bracket and pulley is questionable, as the listing states its for a 1985 Dodge Ramcharger. At that time the RV2 Compressor was done and the C171 was standard equipment.

It doesn't make a difference what compressor was used the only thing that matters is the bracket.

I would agree with you on that. Pretty much everything had the C-171 compressor on it, by 1980.

That said, I don't think the eBay post has the year marked down correctly in the listing - for if he did, it would look exactly like the other bracket (see top picture on post #27). It wouldn't be the first time an eBay listing had an error in it . . .

I tell you what, if you were to purchase that listing (#334) and it doesn't fit, I will buy it from you (for sale price + freight).

Not necessarily. The smaller pulley in the first picture was designed to bolt into the ahb/hd alternator bracket because it also holds the newer compressor. 80s vehicles with no a.c. and the normal style alternator could still use the big pulley bracket because they used different alternator brackets and have nothing else to bolt the smaller pulley to.

You might have a point there, as well.
In Oklahoma, the number of cars here without factory A/C you can almost count on one hand (my wagon is one of them - which was imported from New York state).

In the summer, it can get to 110' F (43' C) in the shade, and that is not counting the 80-90% humidity - so we don't see to not many of those no-A/C brackets around these here parts.



Now the real question my wife wants to know is why I bought a no-A/C car, to begin with. I replied, because it is cool to have a car without A/C. She will stare at me while giving the evil eye, before turning around walking off (well you can fill in the blank on whats going on in her mind . . . ).
Come to think of it, saying it is cool to have a car without A/C is, um, not cool when its the peak of summer.

I don't remember ever seeing one on a car, either, maybe the odd diplomat years ago. Most of the non a.c. pulleys I see are on trucks and they are always the smaller ones in that big hd alternator bracket with a denso alternator. To avoid anyone's confusion here is the two different 80s bracket setups. Both on a Chrysler both pics stolen. All 88/89s had the heavy duty type set up.

Our temperatures can hit anywhere from 100+ in summer to -40 in winter so we have to be prepared for anything. And I like cool a/c!

Mike5thAve: The RV2 and the C171 compressors have completely different mounting brackets. So it does make a difference. Trust me. I have all the correct RV2 and C171 brackets. In fact my 1974 360 Cast Iron Intake, will NOT accept the C171 Brackets at all. It will accept the RV2 brackets.

C171 compressor bracket on 74 cast iron spread bore intake. Does not fit. You can’t put the heater hose on, and it hits the thermostat housing.

You would need a later than 1979 intake that has the offset thermostat housing and moved heater hose and temp sensor like this intake. Everything is offset to the left bank.

I know that. I've dealt with both types of compressor.
What I'm saying is the delete pulley you need has nothing to do with the compressor or brackets at all its completely independent of them. The one XfbodyX found is the same part as the picture you posted of the lil red express.

Now to make it even more confusing that offset thermostat intake started in 1979 while they were still using the old compressor.

This boss (black arrow) on the intake is also needed for the C-171 compressor mounting.

The offset thermostat intakes ('79 up to Magnum engines) will work on older cars, but not the other way around.

Chrysler started the offset intakes on all '79 model year small block cars/trucks. That said, the RV2 compressors were used on '79 B-bodies, pickups and vans (without /6). Odd, but the R-body used the C-171's, so not sure why the last year B-bodies didn't also go that way.
Use the R-body hoses, and brackets, you could put a C-171 on a '74-79 B-body (or vice versa).

The /6's didn't adapt the C-171 until 1980 (or maybe '81).
