What's wrong with my compressor - pulleys don't line up

    So I'm finally getting to work on my A/C swap, having all the parts I need. First step I installed the compressor bracket and idler pulley, all good. Then I bolted the compressor on and found the compressor pulley doesn't line up with the idler pulley and drive pulley. The compressor pulley is offset about 1/2" from where it should be. You can see here how the alginment is off:
    WTF is wrong I wonder? The compressor is new from a kit on ebay for the 01-04 taco with the 2.4L. The bracket and idler are used from ebay, unsure of year but I thought they were all the same for all 2RZ / 3RZ.

    Is it possible they sent me the wrong compressor? Is the bracket different across years and engine sizes? Hoping someone can help me get back on track here.

    I know there were at least 2 different compressors used on some model years meaning different brackets idler pulleys.

    Your going need either the right bracket or the correct compressor for the bracket you have.

    In this day having the wrong parts pulled is all to common.

    Do I know about that... I work at a dealership as a mechanic and it is at least a once a week thing just for me that the wrong parts are ordered. Considering having the parts people be pallbearers and my funeral so they can let me down one last time:rofl:

    According to parts.Toyota.com the bracket is the same, there is only one part number 88431-34020 so I didn’t screw that up. But there’s 2 compressors, one for 95-00 and one for 01-04. But my eBay kit says 98-04 so I could have got a pre-01 compressor?! Hope they’ll fix that for me…

    I keep telling everyone, before u order anything any where, plug you vin into a dealer online site...that will yeild correct#
    Like mcgeorge, that will tell exactly what the one u should have, sometimes even a months difference mfg date is diff part#...

    Then you can take # and search for best deal........
    If you want to avoid counterfeit, places like mcgeorge maybe the way to go....I usally wait until a have 5 or 6 items needed...
    If you buy from others make sure feedback backs up them selling real toyota parts.

    What would really help is if someone could take this measurement for me. That would confirm that I actually have the wrong compressor.

    Here's the Denso 471-1222 compressor they list as compatible. I'd order this right now if I knew that would make my problem go away, but it sure looks identical to the compressor I have.

    Ive searched and they all say this is right for 95 to 04....
    What about the alignment with the crank pulley, center one....

    Key word here is “compatible” doesn’t mean it’s correct. Second issue is eBay. 3rd. Just put it next to the OE you took off.

    You do have the correct pulleys on your crank ?

    Your just replacing the original system or adding to a engine without AC?

    I just took the compressor to a parts store and they looked it up and said it’s the correct one for the 4 cylinder engines. I’m swapping this into a truck that never had it so I don’t have an old compressor to compare. The crank pulley and idler pulley line up but the compressor pulley ends up 1/2” toward the firewall from where it should be.

    here is the problem, measuring from the outside of the bolt hole on the casting to the inside of the pulley, I get 1.5” on the compressor and 2” on the bracket. The idler pulley on the bracket matches up with the crank pulley.

    On all the compressors I’ve seen the clutch looks the same as this one, pulley grooves closer to the engine. If that pulley was reversed the grooves would just about be in the right place, but it’s part of the clutch and can’t be flipped around. I did notice that the compressor listed for the 5vz, denso part 471-1223, looks the same except the pulley sticks out further. It actually looks like it might fit, but that seems outrageous. Still, I know there’s a 4Runner with the 5vz at a nearby wrecker so I’m going to investigate that tomorrow. https://www.amazon.ca/Denso-471-122...ocphy=9000875&hvtargid=pla-569774865765&psc=1

    Pretty sure I figured it out, it's the bracket. After some arm twisting I got the one wrecker in Ontario with a 2.4L Tacoma to send me a picture of the compressor bracket and I can see that the mounting holes for the compressor are offset further away from the engine. I verified this by measuring with a fine ruler and scaling to the width of the pulley, the 2.4L bracket is 1.5" from the casting at the bolt hole to the inside of the pulley, vs. 2" on the bracket I have. So to the person searching this thread in 2035, here's your answer: The bracket for the 2.7L is different from the bracket for the 2.4L, even though Toyota gives the same part number.

    I switched a 3rz to a 2rz about year ago. I just pulled same bracket of 2.7 and went right on 2.4.
    The harmonic balance and all its pulleys lined up same........time case exact same between the two.....
    Only difference I know is oil pump gear is different.......thicker....


    tried to get better pics, but theres coils above and frame and sway below...
    all I got was a bunch of grease on my hairy arms......
    But thinks it shows enough that my compressor is same as yours.......clutch wheel center is about 2" mark.....
