anyone got a twin groove pully for A/C

Dave;
I may be wrong, but, it looks like the upper a-arm for the Manta/Ascona. If for sale, how much for the 7 blade fan?

Dave,
That mount is for a generator, so '68-'69 at the latest. Can you get the P/N off that arm? It may be for Manta/1900, like Gene said.

[nobody]

I didn't know what the bracket was for but could tell it lined up on the opposite side from the alternator. As for the A arm some of the tag is missing, all that's left is 10 110. Every time I dig through that shop I find something else. I had to have moved that A arm 4 times and just noticed it was new and not GT. I was looking for the plastic tops for the front shock mounts, go figure. I even found a rebuild kit with brushes for a bosch alternator. I still need to get pictures of the condensors so you guys can tell me which is which and a picture of that fan unit. I was told it was from a GT but it's not like any I've seen pictures of.

I was under "Wen's" GT last weekend fixing a water leak and instecting a fuel leak at the fuel pump and noticed that the car still has the original double groove pulley. Obviously, he never removed it when he stripped the AC from the car. It, also, has the AC type lower radiator hose.

This car needs LOTS of replacements parts to fix it up... and I can't remove these AC specific parts without something to put back in their place ....
Something to consider if anyone was to trade for or purchase these items.

[nobody]

Paul, I'll toss in a standard lower hose and standard pulley.

Gene, funny things happen when I procrastinate about going to the post office. It usually means I need a bigger box.

Ok now it's name that part time.

Ooooh ooooh I know. A/C parts. How about blower unit for a GT, condenser and evaporator? Did I win?

Dave;
Jeez, at this rate, it'll be a semi trailer by the time it gets here...

From hole spacing? Definitely '66-'69 1.1 engine generator bracket then . . .

Picture is worth 1K words . . .

Thanks Otto, I've never dealt with AC in any of the Opels I've had so it was all greek to me.

Gene you don't know how close to the truth you are. There was originally planned for a flatbed to pick up a car and a slew of parts and take them within driving distance of you. BTW you'll see the fan on Monday and the 2 caps.

Dave;
That's cool, I'll keep an eye peeled for it

Here's my final version, fabricated driver side A/C compressor mounting bracket . . . picture explains all!

On to the mockup of the required passenger side alternator bracket!

[nobody]

On a side note I'll probably take the condensors and Evap with blower to Utah with me. In case anybody that is working on an AC system and might be thinking of making the trip. Price is show up and get them for free. I'll check out the fan unit tomorrow for function. If these are common items let me know and I can just leave them in the shop. I'm not well versed in Opel AC so the parts will not be used here.

Quick update on Kadett A/C compressor and "moved" alternator mods thus far.

Received A/C dual crank pulley and WP fan spacer from Gene . . . thanks. Didn't realize how handy that spacer would turn out to be until working out new accessory drive belt paths later on. BTW, thanks also to Dave for sending his dual pulley, it will be used, but for a different project.

Fabricated passenger side alternator mount from '68 cast iron airpump mount . . . thanks Rodney. Purchased '75-'83 Scirocco "deep cup" alternator pulley for correct belt path and to solve alternator fan to WP intake hose clearance problem. However, now rear crank pulley/WP/PS alternator belt path exhibited interference at WP intake (lower radiator outlet).

Initially thought about solving problem with idler pulley but found better solution by driving only PS alternator from rear crank pulley and fabricating 1/2" thick WP pulley spacer from original A/C WP fan spacer . . . again, thanks Gene. Used this spacer between WP drive flange and pulley to move WP pulley forward by 1/2" and now aligning belt path to drive both A/C compressor and WP off the crank front pulley.

Due to the larger front crank pulley, WP speed will be increased ~10%, aiding coolant flow at idle . . . not exactly a bad thing down here in Texas! "At speed" engine RPM is lower than other models due to the Kadett automatic's 3.18 gearing. The result is that the WP now will turn at about the same speed at 70MPH as our 3.44 geared cars do.

Again, thanks again to all who helped out this far with parts and stuff. A few finishing touches to these pieces and then on with the rest of the Kadett A/C installation. Once I've installed these pieces in the actual car, I'll post some pics. So far, I'm pretty pleased with how it's going . . . although it's taken quite a bit longer than planned to get here.

Might give others considering A/C some ideas, so here's my latest Kadett A/C WIP report with pics:

1. Right side alternator installation: installed regulator on right side radiator frame, extended correctly color coded alternator wiring loom, mounted '80s Scirocco extended alternator pulley, cut 1/2" off lower radiator hose for pulley clearance, modified '80 Accord alternator fan guard, modified '68 air pump bracket and fabricated alternator belt adjustment bracket. Alternator is driven by a single P/N 13300 V-belt off the back A/C dual crank pulley.

2. Left side compressor installation: machined original alternator bracket for use with ND10P08E A/C compressor, machined .540" WP pulley spacer and modified stock alternator belt adjustment bracket. Compressor and WP are driven by a single P/N 15375 V-belt off the front A/C dual crank pulley.

3. Front of radiator condenser installation: trimmed front of radiator sheet metal for condenser clearance, welded two GM O-ring style fittings to condenser in place of hose barbs, fabricated condenser mounting brackets, cut two holes, 1" and 1.375", in radiator mount sheet metal for A/C hoses and fabricated 'high-side', compressor-to-condenser O-ring style hose assembly.

4. Left side receiver/drier installation: modified '80 Accord coil mounting bracket to fit slightly larger diameter receiver/drier, mounted assembly to back of left side radiator mount sheet metal, fabricated 'high-side', condenser-to-receiver/drier O-ring style hose assembly.

Otto;
Is this the engine compartment side? Or have you done anything on the interior?

Nice work Otto, lot of work in the comp mounts! Are you going to use R-12 or 134-A for your A/C system?

Neither . . . I'll be using Duracool, a really 'cool' alternative which I'm already using in my Bitter's A/C. This fluid is even more efficient than R-12 and more environmentally friendly than R-134. It even meets the next phase of TÜV's A/C fluid environmental requirements.

Just installed my 'one off' fabricated clutch fan and thought I'd post the fabrication dimensions, parts used and my reasons for bothering with this.

First, a little project background. After fabbing all the pieces to remount the alternator at the pass side and mount the compressor on the driver side in my Kadett, I found I could not drive both the alternator and water pump off the crank dual rear pulley as is normally done with the alternator on the driver side . . . WP belt path clearance issues with pass side alternator.

Solved this by only driving pass side alternator from crank rear pulley and driving WP and compressor from the crank larger front pulley and using .550" to space WP standard pulley and fan blade forward for crank pulley and compressor clutch fan blade clearance and WP belt path alignment with crank front pulley.

All of this worked fine for my stock, solid mounted, 5-bladed fan. Since front crank pulley is ~13% larger than the stock pulley, the WP and fan are driven ~13% faster. Not necessarily detrimental as far as the WP is concerned, especially down here in Texas, but not a real good solution where the fan is concerned . . . additional drag from higher driven speeds.

Decided to look into mounting a clutch fan to negate the additional drag from the solid mounted fan. Anything you can do to reduce loading on the engine is beneficial from all points of view and especially so with a completely stock engine like my Kadett's. Another consideration was that I wanted to be able to use any stock '68-'74 water pump, not the special '75 'clutch fan' pump with its fixed position, non-removeable drive pulley.

Had a fan clutch (any 3.0 engined '72-'79 BMW) from a previous 'U-Pick' used parts emporium foray, an ~'80s Opel CIH clutch fan adapter WP pulley and an asymetric five-bladed black plastic fan blade from Germany and a stock WP pulley. These are the four items I used to fabricate my Kadett clutch fan assembly to use with a standard '68-'74 CIH water pump since belt path is altered.

Took three tries to get all clearances right, so I won't bore you with details of the first two attempts. Here's my final version in detail:

1. Machined the outer fins off the BMW fan clutch to fit inside the Opel CIH fan blade mounting recess. Without those fins, everything fits exactly!
2. Mounted machined clutch to asymetric 5-bladed Opel fan assembly with eight 1mm washers to space fan blade backwards on clutch by 2mm.
3.
