Well, here I go again...the alternator belt disintegrated and took out the serpentine belt. I have it torn down to access the compressor, which will come out tomorrow. The clutch bearing feels mighty rough. Everything else turns smoothly. I'm gonna try to fix it without disconnecting the refrigerant lines as I just charged the system earlier this summer. I've been doing some searching and found Steve's source for a new clutch bearing (at least I think I can find it again!). In the somewhat unlikely event that the clutch itself is shot, does anyone have a source? So far it's been a fairly routine job. Only the hidden bolt for the coolant hard line gave me a little fit, as I first tried to remove it from the wrong side. Sometimes I can't get 50/50 right half the time!

Guess these links will be helpful then:

Thanks, Man
I had looked at both of those, after wine. I'll post tomorrow before it's too late to order stuff from here.

For those of you who are not taking advantage of the climate control system in your 164 cars, fix all the stuff! Steppers are a piece of cake.

You might want to test compressor to be sure it rotates to be sure it didn't throw a rod like my friends I posted pictures of exploded view couple days ago. He ate up side of alternator belt and kicked serpintine belt off pulley a couple grooves from bearing failure.

OK the compressor is sitting on a piece of plywood on top of the engine. Now, can anyone give me an easy way to get the nut off-the one in the center of the clutch assembly? I need to keep everything from turning while I wrench on the nut.
Thanks!

Use your battery charger or battery to engage clutch and a strap wrench to hold pulley then while holding strap wrench ratchet off nut CCW aka lefty loosey. If you have air impact gun put it in reverse and take makes it easier than ratch but you need clutch engaged.

See my pictures in post 7 of this link I am installing nut using battery charger and strap wrench so you need to reverse strap wrench to loosen: http://www.alfabb.com/bb/forums/showthread.php?t=24963&highlight=sd-709

I was just out trying to get the clutch to engage. I wired a spare battery to the compressor, grounded on compressor frame. Got no click, wires just got hot. I'm gonna try heavier wires (jumper cables) but I think I'm doomed.

Sounds like maybe clutch coil is toasted if you hooked negative to case and positive to red coil wire. You don't need bigger wires than one coming out of coil.

Does compressor crankshaft rotate freely 360 degrees when turning nut? If not internal problem. If it does rotate OK try screwing in a couple coarse threaded 6mm bolts into clutch and use a flat bar screwdriver to hold clutch when loosening nut.

Steve-
The compressor itself turns fine, so I think it's OK. I'm sure your bolt method will work. Where can I source a clutch module? I need to get this heap back on the road as I really don't like "sharing" my other Alfas!
As an aside, what would we be doing if we didn't have these cars?

Well, right now I am doing a major a/c evaporator replacement on my wife's like new with only 212,000 miles on it Jeep Grand Cherokee. The 164 a/c system is a cake walk. I had to pull entire dash and lay on front seats and boy is it heavy to even get to box that holds evaporator, heater core and blower motor.

Let me show you dirty and leaking core

Just found out that the evaporator in our Jeep Grand Cherokee (98, only 140K) also needs replacement. Our local garage that we use for almost all repairs quoted $850. They also said they need it for 2 days. After looking at the photos, it looks like a good deal.

Probably a fair price as ebayer in Miami offered job for $1000 recently and then came back with new listing of about $850 I think.

I have more time than money so I do my own repairs.

You might try Polar Air for clutch coil I printed number of it pulley and clutch in link above. 7x5 pulley bit hard to find but coil maybe easier and you can replace pulley bearing pretty easy.

Check your compressor model number if label readable and see this link: http://www.polarbearinc.com/PBPC/homepage/product_CC.html

Maybe this one: SD-709 12V BULLET #607 7409, 7207, (708) 7401, 7402, 7416, 7427, 7529 Their number CC 1800

No 6mm/1.25 bolts in our little town, so it's off to Ft. Smith this morning to get some. Sure wish my compressor was plumbed in so I could hit it with impact!

CORRECTION on bolts: I posted this some time back "Three bolts I use believe it or not are from a GE washing machine shipping plate to hold transmission solid. However COMMA They are 1/4"x 20tpi about 1 1/2" to 3" long to work with my triangle puller shown in pictures".

 

[aralfa8589]

You caught me in time. Now I'm nervous. I wonder if they're same as my Milano, as I'll be driving it. Maybe I'll just buy 3 of every pitch available.

Yes they are same size as you would use on Milano compressor clutch plate. Please post what size you find fits both cars so I can correct/update my procedure posts.

I decided to let my fingers do the walking...called 2 bolt supply houses in Ft Smith. The first one said 1.00 pitch was all that was available. The second one called their metric distributer, and found a .75 pitch which is a finer thread. One way or the other, that thing is gonna get dismantled today.

 

[aralfa8589]

Hmmm...I believe we sometimes do too much thinking. I jammed a nice fat chisel in between the case and the pulley and tapped it snug. Stuck a 1/2" drive socket with mongo breaker bar on the nut. Whacked the bar a good lick with my trusty dead blow hammer. No problemo!
