Dave;
It seems I have run into a batch of Mantas. I have one parked in the driveway right now (74 Rallye, rust bucket, being stripped for parts) and another waiting for me out in west GA this weeked (another 74 Rallye, again a rust bucket, but, has great parts) and another 75 Manta in east GA I intend looking at this weekend (again, another rust bucket waiting to be stripped)

Still looking for twin pulley A/C crank pulley and right side (Manta/1900), aluminum A/C pump mount . . .

 

[nobody]

Otto, this weekend I'll be picking up a twin pulley in a box of parts. I'm not sure about a mount but anything is possible. I'll post condensor pics so ya'll can help me identify what goes to what.

 

[RallyBob]

Otto, if Dave's pulley doesn't pan out I should have one too. No aluminum compressor brackets though, the ones I have are steel.

Right . . . correct . . . uh, passenger side

Would've helped if I'd said right, as in correct or passenger, side . . . Senior Moment . . .

Right side air pump bracket . . . '68 1.9?

Thanks for the twin pulley offers from RallyBob and nobody. Found an extra right side GM compressor bracket, BTW, but not going to work for what I want to do, so I'm not going to just cut it up.

Anyone have a cast iron air pump bracket or two from a '68 1.9 engine . . . and, maybe, an air pump that goes with it?

Two different projects: bracket and pump - modify pump to use in reverse (vacuum) to evacuate my 2.15 SSD crankcase; bracket only - modify bracket for mounting Nippodenso 10P08E compressor (very small, rescued from junk-yard many years ago for use in Opel) for hand-fabricated A/C in '69 Kadett.

Based on ~630 mile round trip to San Antonio last weekend, these old bones don't take too well to long, non-A/C drives in the summer heat down here anymore. A/C is on front burner, as I'll likely take '69 Kadett to OMC . . . if I go. Now you know . . . any of those in anyone's stash somewhere? I'll document and post on one or both projects.

One of the ultimatums I had made to myself concerning the drive out to the OMC this year was I would only go if my wagon had A/C (my Canadian blood doesn't tolerate heat and especially humidity). That's a moot point now since I don't have the money to go and the wagon is nowhere near completed anyway. But, I was going to use the A/C I stripped from my Nissan Sentra which has a nice, efficient, lightweight compressor that will easily fit the turbo wagon. That said, I was going to have to make a mounting bracket for it anyway.

Otto, if you have a detailed drawing I could probably fab up an aluminum bracket in a couple of hours for you. Just a thought, and the practice wouldn't hurt me

It seems the guy with the wagon and GT had another wagon previous that had AC. I'm absolutely positive the condensor and pulley are there. I won't be needing either but they come with the parts lot. I'll be picking them and the wagon this weekend. There may be more GT and wagon AC bits yet uncovered on this one.

Thanks. Let me know when and what shipping, etc. would be. Thanks.

Sounds very intriguing, Bob, thanks for the offer. I'm enclosing a picture of the compressor with all the pertinent mounting dimensions so, if you can do the mockup of the block and crank with twin pulley for bracket dimensions there, all should be good to go. Let me know if you have any questions about compressor pic. Thanks for entertaining this.

 

[nobody]

Otto, do you ever get out to Fort Smith Arkansas?

Not normally, but who knows . . .

How would you want it configured, as far as the 'clocking' of the compressor? I can see the bolt (size?) for the belt adjustment at the top of the pic...where would that be situated (since I don't know the routing of the compressor lines it would be important). What diameters are the lower mounting tab holes?

Block face to c/l front (dual) pulley measurement?

Bob,
How about a measurement from the centerline of the "V" of the front pulley from the dual pulley crank pulley to the machined front face of the block where the timing cover mounts? I get ~110mm estimating from standard single pulley at ~95mm for this dimension . . . close? Need more accurate measurements for some drawings I'm working up. Thanks.

Just did a mockup on the Kadett and realized there are serious V-belt drive to lower radiator hose interference issues if pump is mounted on right side of engine. Though I'll have to fab two brackets, much easier to mount alternator on right and compressor on left where alternator normally mounts. Come to think of it, I used the same arrangement on two GTs where I installed A/C . . . don't know what I was thinking.

I'll mount the pump low, pivot axis below pan rail, so that I don't have suction or pressure hose mounting interference issues at the distributor. Not sure yet, but may have to resort to idler pulley for pump belt tensioning. Still'd like to know c/l of front dual drive pulley to block face dimension if you have time. I'll toss together a dimensional drawing of required mounts.

I have a couple blocks sitting on an engine stand waiting for a pulley to measure from, but the double A/C pulleys I have are in my storage trailer, which is not local to me. If I can swing by there this weekend I'll try to get one. This weekend happens to be a non-automotive weekend, just trying to clean up some messes I started!

It looks like tomorrow is a go car crazy kinda day. I'll pick it up regardless and post dimensions on it. The big fireworks display for the town is so close I've been overwatering the lawn. No going anywhere that doesn't include an Opel this weekend.

 

[bear]

Otto, don't know if this will help you, I'm kinda out to lunch on anything other than a GT, but Beta Carotene, has a complete Manta AC system up for grabs in the classified ad section. Might be what you're after, IDK.

 

[nobody]

Otto, I didn't get a chance to measure it. On the other side tomorrow it's southbound.

Dual pulley question

Otto, I didn't get a chance to measure it. On the other side tomorrow it's southbound.

Is the alternator/water pump V-belt driven from the rear pulley of dual crank pulley? Assume so . . . thanks.

 

[rangerrick]

Yep. is on mine!

Otto

Yes. On my 1972 GT with GM A/cond. the rear pulley drives the water pump and alternator. Front is for Air/cond. compressor and idler pulley.
