80 series AC compressors (3 Viewers)

[enox]

AC cycles on/off at 40° any ideas how to keep the compressor on longer?

I'd relocate the thermistor but it's a pain to get to, unless I remove the evap.

Ordered this for my 1990 HDJ81 with front ac and center fridge. The clutch isn’t correct. The correct clutch is part # 88410-35120. The clutch on this compressor sticks out about 1/2 further than the idler pulley.

Mine must be out of spec I have the same measurement. Thank you very much for posting!
Edit: it's hard to see in the photo there is some twerk to the belt. It's been running excellent for now, @Brino1983 thanks again I was probably on my way to throwing a belt. If you would please post up where you locate the correct clutch. I can only find that part number with a serpentine pulley. Or if the pulleys interchange without much science.

Gotta be careful that the replacement compressor uses the same oil that's already in your system. For replacement I use 471-1141 (10PA15C) because I want it to come with the mineral oil that's originally in our R12 systems. I use R12A as my refrigerant.

Very weird yours came with the wrong clutch....?!?

For sure! I never noticed it being off until @Brino1983 post. If anyone can post the V belt version of the correct clutch that would be very helpful. I don't have great googlefu and can only find the serpentine version clutch.

That's an excellent point @jellis . I also changed the system to R134a and had to replace the oil and O rings when I got the new compressor.

The clutch I quoted wasn’t correct. Back to the drawing board.

Wanted to add some information to this compressor thread. Quoted from my own build thread :Thread here

This 1997 HDJ80 AC system is R134A from factory.
Since I have added the console fridge and this 80 has the rear AC, I want to make sure the AC system is working well while it is apart.
Earlier, I refreshed the interior AC components such as the TXV, evaporator, fan, door foam, and the condenser. The fridge was mostly rebuilt and the compressor looked to be original.
The HDJ had 2 compressor options for this year a 10PA17 and 10PA15. This 80 has the 17 because of the additional cooled components (rear AC and fridge). I believe the 15 came with any 80 without the rear AC and with or without the fridge. The 17 came with the rear AC option and with/without the fridge.
OEM 10PA17 part number for this HDJ80 is 88320-60610. However, after some research of photos and part numbers, the FZJ80/LX450 compressor is already the 10PA17 type with a different pulley/clutch assembly. The size of the physical compressor is exactly the same.
Denso 471-1166 is the replacement compressor for the 1FZ/LX450. I purchased it and a new clutch assembly (88410-22480), shims (88335-14020), snap ring (90099-07114), and a star type snap ring (90099-07125).
Removal of the clutch is very easy - 1 bolt and two snap rings.

Some photos to compare after the new clutch was added. Additional photos in my thread linked above.
