New clutch with new compressor? Now you have me wondering if you have a hydrostatic block on the high side translation; the high pressure is so high to compressor can't turn or the compressor is locked up.
I usually put a video on YouTube and copy the link here it's easier, takes up less bandwidth
I wouldn't expect the air gap to be large on a new clutch but that's easy to check.
Does it actually start cooling? Clutch is slipping bad that is unbelievable on a new compressor??? Can you turn the inner part of a clutch by hand? that is connected to the crankshaft of the compressor if you can turn it by hand it's not locked up. I've not spent a whole lot of time with these particular compressors but think you might be able to turn it with a ratchet. But the compressor should turn relatively easy with the clutch disengaged.
A super high head pressure or complete blockage of the discharge line from the compressor or even to the may cause extremely high head pressure so much that the compressor clutch slips,. We need to get gauges on it,
was not able to turn it by hand but with a ratchet yes but it felt like it was grinding a little bit. I did moot have to force it with the wrench but it did feel like itwas grinding. I assumeit should be smooth. and yes it does blow cold air just the clutch starts to smoke and the compressor gets hot even for those 15 seconds of the ac being on
Well it's pretty obvious what you need to do, or have done,. Before you rip it out, I would suggest one thing, Hotwire the clutch directly from the battery,
Check the voltage of the wires coming to the clutch from the truck you want a eleminate any voltage problems
I don't know if it can be saved by taking it off putting oil in it and turn it with hands, wrenches, and electric drills
We have saved compressors by removing the refrigerant charge and bypassing the controls. on this type compressor I just don't know, it's got what they call a wobble plate and 4/6 pistons in a horizontal configuration I don't know how it came this way or if it was run without oil, but the original one was doing the same thing right?
yes I still have the old one and I believe that is completely locked up. to check if it is locked up I just put the 8mm wrench on the screw for the ac clutch and try to turn it correct??? also if I go too pull a part to get another compressor what vehicles and years could I get a compressor from?
You don't have a replacement warranty on that new one? Question, you do know the oil goes in a compressor that if it's put only in the accumulator it won't get to the compressor until starts running. But new compressors do come with oil as far as I know. Salvage yards have a list they know what fits.
I have a 96 ranger 4cyl manual. my ac clutch stays engaged only when in max ac or just ac. recently changed the ac compressor with clutch, dryer, orfice tube, and clutch cycle switch( attached to the dryer).
if i keep it running you can start to smell a burning rubber smell but the belt looks fine. when the truck is running in max ac I disconnected the clutch sensor and the clutch disengages. i just had it completely drained and recharged. is this new compressor locked up?
