Air con bearings

Thanks i knew that's what you said originally but the front clutch bearing got thrown into the mix somehow which fried my brain . i've done a web search & still unable to find any matching bearings for that 1994152 number even on the the link you provided, is there any other interchangeable part numbers that replace that bearing thanks again

I added the clutch bearing replacement.....because as long as your rebuilding the compressor, why not replace the clutch bearing also. Yes....its for the clutch external to the refrigerant system and the internal components......it was just a thought.......just my opinion of course....

I made a mistake when I wrote the rear bearing part number down. It is 1984152. Sorry about the mistake.

Hello all it's been a while since i started collecting parts for my A/C finely got most of my parts but the compressor crank shaft seals just checking if the seals are the same for the RV2 & V2 thanks ahead guys cheers

Hello guys I want to rebuild my compressor. It was dry and one rod is seized. My compressor is V2 and has flat oil pan. If I have correct information flat oil pan was used from 1969 but my car is DODGE Polara 1962. So probbably the compressor was replaced in the past. So is V2 correct for my car ? Can I rebuild it to RV2 ? I need new pistons + rods, new crankshaft. Is easiest found parts for RV2 so I buy new front bearing cover + bearing and rebuilt it to RV2. Is it possible way ? Do you have experience with gas Easyklima which replace R12 1:1 ?
Kit R134A gas refill, gas R134A refrigerant, R134Aa buy | EasyKlima They are saying no need conversion to R134a. In this case could be possible keep the system with EPR valve. Do you know any shop which sale drier, expansion valve, relieve spring with bal gaskets and so on ? Classic Auto Air closed Original Air Group division.

OK there are 2 compressors...RV2 and V2...externally they look the same but are different displacement...idk the exact sizes without looking them up but the RV2 is about 10 cubic inches and the V2 is 9....the smaller V2 was used on A bodies and possibly pickup trucks...bigger cars used the RV2...either will bolt on and many cars wind up with the wrong one...you can bolt either the flat or the V shaped pan on either compressor....applications where the compressor sits level get the flat pan, applications where the compressor is tilted over get the deeper pan...wrong pan will either hit the engine and not fit or wont pick up oil properly (may be why it threw a rod)....the crank, front cover, bearing, and pistons and rods are different between V2 and RV2...the RV2 crank has plates attached to the counterweights with phillips screws, the V2 does not...the RV2 pistons have notches in the top to clear the reed valves, the V2 has flattop pistons (v2 shorter stroke) ...the V2 has a front bearing that is smaller ( #205 ) which is readily available and many sites list it as fitting an RV2 but it does not...the larger RV2 bearing is NOS only...so you really need to take it apart to see what you have....I THINK the blocks and heads interchange but I don't know that as a fact

Thank you for the detailed description of the differences V2xRV2. My compressor is disassembled. My is V2. As I wrote was total dry so I thing it is the reason rod is seised. But compressor is tilted in my car so I need the deeper pan and could be as you wrote. If original compressor for my car is RV2 previous owner have to replace it without knowledge you wrote abou pan. When I start look for parts I did not found supplier for V2 crankshaft and pistons. All what I found are for RV2. Although on other treads someone wrote V2 was in A-Body, B-body and pickup trucks I suspected bigger cabin B-body need bigger compressor. You are confirming it. So now is clear and except for the crank, pistons with rods, gaskets, front bearing cover + bearing I heve to looking for oil pan. Do you know the diameters and width of front bearing ? What about the gas I asked before ? Also I need new dryer and expansion valve. Do you know where to buy them ?

I believe Mopar part # for RV2 front bearing is 2019681...i don't think it crosses over to a "standard" bearing size but outside and inside diameters are larger than the V2... you might be better off trying to find an RV2 with the right pan in the first place and maybe more salvageable parts? all my research has been for my 68 so i dont't know what fits a 62...my drier and valve were available through regular aftermarket suppliers like 4 Seasons but no idea for your year....as far as the replacement refrigerant you are referring to ,I know nothing about it as I can still get R 12 around here

RockAuto.com sale front bearing for both types but both have same diameters 25mm inner; 52mm outer. Bearing on my compressor has inner diameter 7/8" (22,22mm). Outer diameter is 52mm. On the front bearing cover is not to much space for bigger diameter than 52. It looks like different is only inner diameter RV2=25; V2=22,22mm. So I thing bearing cover for RV2 has only one different bigger diameter for the shaft. My has diameter 23,4mm so if I increase diameter could be usable and I no need ne one. But I thing it I am not sure. You are lucky you can buy R12. Here in middle Europe I can not. Thanks for tip for 4 Seasons. I did not know this supplier. They have expansion valve. I need to find the drier yet. Thank you so much for your help.

rock auto's listing is wrong...I know cause I that's where I bought the one I'm holding...its for a V2...52mm od, 25mm id and 15mm wide...the RV2 bearing is 62mm od, I think its also 25mm id but only 11mm wide... the shaft is 7/8 on both but there is a raised area where the bearing presses on(25)...the RV2 crank i'm looking at still has the bearing on it so i'm not positive of the diameter where it presses on ...it appears to be 25 but I can't measure it without pressing it off...the crank od may be the same but the width is probably different so I don't think you can just put the V2 bearing on the RV2 crank and re-use the front part of the compressor

 

[Mila Korinek]

You are right. The crank shaft has bearing mounting diameter 25mm. Bearing cover from V2 is not possible modified. There is no material for increasing from 52 to 62mm. Use smaller bearing on RV2 is to risky. There is higher radial force from puley. Now is clear. Thanks.
