    85 Supra -Condensor motor replacement?

    Hey everyone....

    I am in the midst of re-cooling my 85, (condensor, compressor, expansion valve, etc) and my condensor fan sounds awful. I have thoroughly mangled the nut holding the fan on the motor (yay me!), and was hoping to find someone who knows of a replacement? I might be able to get the fan off-so a "bolt in" motor replacement is ok-if its the best I am gonna do. THANKS!

    Some sites state that the blower fan assembly has been discontinued.
    Toyota part number and procedure in this thread:

    I looked on Amazon:$100.
    Another dealer: $65.

    Perhaps in NH,you can find one.

    From another JDK A/C thread...Thanks Jim!!

    Here's a link to a FAQ that may provide you some more information.

    Greg is correct. The kit used Spal fans. 10" or 11". Don't recall.
    Yes, most any aftermarket fan will need to be wired seperately from any factory feeds.
    You can use the existing fan feed as the relay trigger.

    Stock condenser fan is no longer available since 2017 (when I asked for one). I ended up using a DeRale 10" as mentioned later in this thread...

    Sooo...thanks to the replies and the info-the knowledge base her is great!
    Does anyone have any technical specifications on the resistor in this setup? PN 886351-4060-i beleive. Mine has snapped a contact clean off and I doubt I can resolder.
    I tried cleaning the space between the actual fan, and the motor housing-and when powered with a train transformer-it sounded a whole lot better. My thought is to re-install, but with thumb screws-in anticipation of sourcing a replacement. I am also going to make a hardware cloth screen for my new condenser-in anticipation of the fan flying off of the shaft-due to the damage I caused in dis-assembly. Any tech specs on that resistor (or link, etc.) really appreciated.
    THANKS!!

    Is there a resistor in the condenser motor fan circuit?
    I didn't know that there was one!

    YES,there is one! Discontinued....

    What he said!

    I went out and had a look at my cars and darned if you're not right!
    I thought that it was the fusible link but it's definitely not.

    I ohm'd it out with a good quality meter and it measured about 0.1 ohm. It's hard to be more accurate. Then I got a good photo of the part and it appears to be 0.13 Ohm (130 mOhm).

    It's obviously 0.13 Ohms and if I were to guess from the shape it's probably a wire wound ceramic cement encased power resister rated at about 1 to 5 Watts.
    They are reasonably uncommon. I would imagine that something like:

    https://www.digikey.com/product-deta...13CT-ND/596406


    Vishay PAC500001307FAC000
    RES 0.13 OHM 5W 1% AXIAL
    130 mOhms 1% 5W Through Hole Resistor Axial Flame Retardant Coating, Pulse Withstanding, Safety Wirewound

    would work. They are quite inexpensive at US$1.24 each.

    You would have to make it weather resistant by shrink wrapping it or some other means. I would order a few of them and try to use them before making a permanent enclosure to see how hot they get. If they run really hot, by wrapping them you could make them run even hotter and possibly run the risk of them catching fire!
    The current flow through the resistor will determine the actual wattage dissipation. The motor resistance plus the 0.13 ohm of the resistor will set the current flow.
    12.6V / Total resistance (0.13 plus motor resistance) =Circuit current flow.
    Power dissipation is (I x I)/R where I is current in Amps and R is the 0.13 Ohms of the Resistor
    (help me out here guys - I'm REALLY rusty doing these calculations!)
    I could actually go out and measure the circuit resistance, but i put the plastic cover back in place and I'm too lazy to take it off again. Sigh.

    Let us know what you try.

    Dale,that is a good and inexpensive solution!
    The old broken one is ceramic and about 5 watts.

    A resister is a CURRENT LIMITER,not a voltage drop component and it's important,I guess.
    My De Rail unit works as is, through the existing wiring. It must go through that resistor!
    I checked 17 sites for that part # 88635-14060. NADA!

    My way of mounting would be the same way:With a metal strap. Just use galvanized plumbing pipe hanger stuff.
    Heat shrink will melt away asap.It's going to get HOT.
    Again,excellent solution,Dale.

    Well, I'm wondering what the resistor is actually for.
    I'm assuming that it's in the circuit in case of the motor going dead short. There is a fuse in the circuit, but I would assume that the resistor is to keep the current limited to a value that will blow the fuse quickly, but not enough to melt wiring. I really am curious as to the resistance of the motor to find out what the current draw is for a normally working fan.

    10 " DeRail:
    https://www.ebay.com/itm/Derale-Engi...75.c1#viTabs_0
    Rated @ 5.3 amps. Start up amp draw,more than that.
    The weenie fan has to be much less!
