Anyone installed an aftermarket ac system from Maarten @ Cruiserworld into a HJ61??? (2 Viewers)

[sved]

Yep,

You can see in the diagram that they are connected to Pin 2 Black/white and 9 Yellow.
Those 2 are the only one you need. The black and white with the spade connector is the one you do not need. Must be for the VSV switch (Idle upp) . The pump is connected to pin 2 in the diagram.
On the pressure and thermistor switch is doesn't matter which spade you connect because they are just switches.

Made a little more progress today. Cut some brackets and secured the condenser and dryer. The high pressure line hitting the dryer is gonna be close. Have not tried to connect it yet. Test fitting everything and then I’ll take the wiring. Hopefully this weekend.

I had to cut some mm plastic at the back of the grill to make it fit. Tight but it worked out.
I see you had at last the same hose configuration.

That is good to know Sved. Quick question I should have asked before I re-clocked the compressor…did your compressor come with the appropriate amount of oil in it? There are no labels on this compressor or in the box indicating it does or does not have oil in it.

 

[sved]

Yes , the compressor is pre oiled. The compressor came in the OEM Sanden package with a ''pre oiled '' label.
My AC guy just vacumed the system and charged it with the right amount R134A . I think it was around 850 Gram's. Tight and trouble free since then.

Ok. Good to know. I’ve been told they come with oil unless specified. I really don’t want to remove the compressor again. The way it bolts up it’s a PITA to remove and mount back up. Those two lower bolts????

 

[sved]

The 2 lower bolts are added for testing your patience , but it is possible . f iI remember correct i started with the lower first, not quite sure.

Hopefully this is the final routing of the hoses. New o-rings wiped down with PAG oil and connections made. Sucked it down with the vacuum and will let it sit overnight to see if there’s any leaks. Once I pass this step I’ll secure all the hoses and file down the inside of the grill to clearance the dryer. Then onto the wiring and a system charge and we should be good.

Good news…the system held pressure overnight.

Built a small harness following @sved ‘s direction and great posts outlining the process. Found a few clips off of a spare 12HT harness I have in my shop allowing a clean connection at the compressor as well as under the glove box. Hope to charge the system with Freon tomorrow after work Then take a break as my son @mcguirejohnson comes in Thursday from Fort Collins. We have a suspension to do on my 80 (going back stock height), pull some locked axles from another 80, change the oil in my Duramax and then we are driving to Fort Collins on Saturday. Goal is to spend Father’s Day with the boys and then burn my way back to TX on Monday. Then I’ll spend some time clearancing the grill, securing the ac lines and put the dash back together. Then this job should be complete.

One more thing,
On my provided lookalike AC switch they had the wires connected to the wrong spades.
Either the light was on or the compressor was activated.
Switched the spades in the connector and bang light on ment ac on .

Bingo Mr SVED. I’m vacuuming the system and decided to turn on the key to check things and that blue light was stuck on. Then I remembered you mentioned this. Went back and found this post and swapped the two red wires and now the button seems to function correctly. These two pics are with the key in the “on” position.

Making progress i see. If you bridge the 2 connections on the pressure switch you can dry test the function of the switch in combination with the function test of the pump clutch. No need to charge the system for that. Don't start the engine ofcourse .

I jumped a bit ahead and put two cans of Freon in. The temp at the vent hit just below 40 degrees and the clutch cycled off a few times. Leaving it there for right now. The blue light in the switch stopped working but it still engages the compressor when it’s pushed in. Could be I shorted out the bulb since everything is out of the dash and floating around.

 

[sved]

I had the same issue with the blue light .. Had the suspicion they used a 12V bulb . So i switch to a spare 24V bulb and that did the trick.

Another prove that the supplier didn't have a clue what they were doing ..........
