Looked up the Dayco pn 89007 on Amazon.com the listing only showed the pulley.
Is the bolt, washer, nut and spacer included with the pulley?
As shown in the E-bay listing.

[jimmo]

No, I machined the spacer and gathered the rest of the hardware to go with it. The dayco part# is the pulley only.

[Ollie]

OK, Jimmo keep up the good work. will be standing by waiting for the availability of the idler pulley extension. So I ca start to work on that side of the serpintine system.
Got a notice from the PO that they are holding a package too large for the mail box.
Should be the Sanden compressor with a serpintine pulley I bought on E-bay.

[jimmo]

Just got the other pieces in from the waterjet. here is a pic of them in raw form. both need a little work to be bolt on ready but at least they are finally here.
The aluminum will receive threads at the top two holes and a counter bore on the other mounting hole to keep the bolt head away from the path of the belt.
The smaller steel bracket will get a threaded spacer welded to it to accept the ac bracket. This will perform the same function as the 1" thick aluminum one I made previously.

[Ollie]

That's great jimmo. I want a an idler bracket as soon as they are ready.
I was correct the package at the PO is the Sanden AC compressor with the serpentine pulley. will post photos of the mock up as soon as I get it put together.

[jimmo]

Nice! I cant wait to see how it turns out with the sanden. Ill machine the spacer in the next day or two and p.m. you when its ready.

[Ollie]

Bringing this back to the top.
jimmo is making great progress refining his DIY Serpentine belt system.
Anyone else have up dates on their DIY Serpentine belt install.
I've purchased jimmo's idler pulley extension bracket shown above in post 193.
I purchased a CS 130 alternator from this E-bay seller billh6800, who will fabricate a custom CS 130 alternator.
Purchased a power steering pump with the serpentine pulley. Both should arrive by the end of the weed.
Also found this site for Goodyear Gatorback Serpentine belts. The 6 rib belt Part number, length from 29" to 120" in 1" increments.
shouldn't have any trouble selecting a belt.
Check it out to determine what belt length and part number to use.

Ollie, I am looking forward to seeing your Sanden compressor install, as I would rather go that route instead of using the R4 compressor, if possible. Please post pics and parts lists when you can. What vehicle are you installing in? What will you be using for hoses, evaporator, condensor, etc?

I'm installing in a 65 Grand Prix. I don't mind changing out the condensor for a modern unit, mine developed a leak anyway. But I'm not sure I can adapt modern stuff to work with my 1965 evaporator...if that is even possible.

As for now I'm still running the serpentine belt on the water pump, alternator and power steering only..it's holding up OK. I have noticed that belt tension must be kept pretty tight since this system uses no tensioner.

What year heads do you have on the engine. The vintage Air bracket mounts to the two bolt bosses on the side of the head. The Classic Auto Air bracket mounts to the bolt holes on the front of the head.
This set up is on a 79 TA, using the stock GM AC. The only change is converting to a Sanden compressor, using the Vintage Air Snaden bracket

RE: VA Bracket

Either thats a new one, or an old one, or they have more that one Pontiac application because my VA bracket, installed new 2 yrs ago, mounts to the front only.

Interesting.
The link is to the latest Vintage Air on line catalog.
Maybe there are two bracket listings. I know the the AC compressor mounting changed in 1969. Prior to 69 the AC bracket bolted to the engine with two special head bolts. in 69 the AC bracket bolted to two bosses cast in the side of the head.
Do you have a PN. or post a photo of the bracket

I'll look. If I recall correctly my bracket had a provision for one bolt boss on the side of the head but, it didn't line up with anything on my head, '67, and it was optional to use it, it's just an extra fastener point. It’s definitely not the bracket shown using both side bosses.

[quicksilver97ta]

Here's mine 141001-PPA.

http://www.vintageair.com/INSTRUCTIO...2005.25.10.pdf

[AROWHED]

For now I have a 455 with 1971 '96' heads, so I have all bolt options available. Hopefully soon will be changing to a new engine with E-heads, but should still be able to bolt anywhere.

[Ollie]

Yes, The E heads have all the bolt options as the stock heads.
I would recommend the Vintage Air bracket
141001PPA. That is the one I am fabricating The adapter for.

[Ollie]

I see what you are talking about.
Yes the Bracket is changed. Look at the small print in the border at the bottom of the page. in the link you posted the revision is rev C 5/25/10.
In the link I posted it is Rev A 2/9/05.
I do have an early bracket.
This is a problem is the modification I have requires the compressor to be moved forward 1 5/8" to line up with the crank and water pump serpentine pulleys.

[Ollie]

Vintage Air redesigned the compressor bracket so it can be used on both early and late heads.
Have ordered the revised compressor bracket and will revise the adapter.

VINTAGE AIR SANDEN COMPRESSOR BRACKET EARLY DESIGN.
SANDEN AIR CONDITIONING COMPRESSOR WITH SERPENTINE BELT.
Anyone following this thread knows I am using a Sanden AC Compressor with jimmo’s serpentine belt conversion. The following is my findings and recommendations.
1. There are two Vintage Air, Sanden to Pontiac Engine brackets. An early version linked at page 2 post #38 and a later version linked at page 11 post 204.
Either bracket can be used in the serpentine belt modification. This first post will be directed to using the early bracket. The early bracket bolts to the head, using the two cast in bolt bosses on the side of the head, and one long bolt with spacer on the front of the head.

http://i361.photobucket.com/albums/o...T/IMG_1404.jpg
Purchase a length of steel flat bar stock 1 ¼ inch wide ¼ inch thick. This modification requires a 9 inch length.
Here in the Seattle area, I purchased this at Tacoma Screw Products, in a 3 ft. length which is the shortest length they have.
McMaster Carr or Granger supply or any industrial supply might also have this bar stock.
http://i361.photobucket.com/albums/o...Extensiotn.jpg
This is a CAD drawing of the spacer to move the early Vintage Air bracket forward 1.625 inches.
Fabricate this spacer the Sanden compressor will be in correct alignment with the serpentine belt.
This spacer requires two ¼ inch spacers, one each between the spacer and head bolt boss.
These ¼” spacer can be fabricated from the bar stock purchased to fabricate the bracket spacer or purchased from.
http://i361.photobucket.com/albums/o...T/IMG_1376.jpg
http://www.aluminumspacers.com/
All spacers used in this modification can be purchased here as well.
When taking any measurement insure the measurement is taken from the flat machined surface of the head.
I purchased a 1ft length of the perforated angle to use in prototyping the spacer. To allow inserting the bolts, the holes and slots had to be enlarged slightly with a rat tail file.
http://i361.photobucket.com/albums/o...ypeBracket.jpg
Number 1Hole is the Forward bolt boss on the side of the head; Hole 2 is the back bolt boss on side of head.
Hole 3 is the forward bolt hole on the Sanden compressor bracket. Hole 4 is the back end hole on the Sanden compressor bracket. Hole 5 is an extra bolt hole drilled in both the Spacer bar and the Sanden compressor bracket. Drill this hole 2” forward of the existing forward bolt hole in the Sanden compressor bracket.

After the compressor bracket is fabricated a 1” and a 5/8” spacer will need to be added to the front bolt.
When installing longer bolts. Purchase bolts with enough length to provide a minim of ½” up to ¾” threads into the head.

On page 8 post #154, Jimmo shows a solid link for tensioner-made from 1” bar stock. That bolted to the belt tensioner and the R4 compressor bracket spacer. Doing some research I found that March Performance lists a large selection of turn buckles.
March Performance lists the turn buckle in various lengths from 3 5/8” to 18”.

http://i361.photobucket.com/albums/o...T/IMG_1428.jpg
This is my idea of connecting the serpentine tensioner. Of course I need a longer turn buckle, but this gives you the idea. I don’t think using the existing bolt will work as the angle is too steep and the turn buckle wanted to interfere with the belt tensioner. The distance from the belt tensioner to the compressor bracket is about 7 ¾”. So a turn buckle of the correct length would need to be purchased and trial fitted to determine the correct position for the bolt.

LATE SANDEN COMPRESSOR BRACKET
Vintage Air redesigned the Sanden AC compressor to Pontiac Engine bracket. If you have this bracket or if you purchase one now this is the bracket you will receive.

http://i361.photobucket.com/albums/o...ressorBrkt.jpg
As you can see this bracket mounts to three bolt holes on the front of the cylinder head and the forward bolt boss on the side of the head, making it compatible with both early and late heads. Mounting this bracket flush on the head or even off set 0.608 using the spacers and three bolts provided with the Vintage Air bracket kit will be OK. Moving the bracket forward 1 5/8” required for the serpentine belt modification using only three bolts. The needle on my concern meter started twitching, as I thought about the stability on this arrangement. Calling upon knowledge gained fabricating the spacer extension for the early compressor bracket. I designed an extension bracket for this late compressor bracket, fabricated from the same 1 ¼” by ¼” steel flat bar stock. http://i361.photobucket.com/albums/o...Extensiotn.jpg
Moving the bracket forward 1 5/8” requires the use of a 2 ½” bolts. However a 2 ½” bolt cannot be inserted in the top bolt hole because of the closeness of the forward angle.
http://i361.photobucket.com/albums/o...T/IMG_1390.jpg
This requires the use of 3” studs.
http://i361.photobucket.com/albums/o...T/IMG_1398.jpg
They are exhaust manifold studs, 3/8 – 16 X 3”.I purchased at a local Auto exhaust specialty shop.
I also found them at auto parts stores.
If the studs have the hex end do not get them, the hex end is included in the overall length, when installed they are too short.
http://i361.photobucket.com/albums/o...T/IMG_1399.jpg
When installing the studs, be aware the bottom hole is open into the head bolt hole. Installing the stud on an engine with the head bolts in place. The threads should be clean enough to, screw the stud in by hand, apply Loctite on the threads, screw the stud in by hand until it stops against the head bolt and back off about 1 turn. If installing the studs on a head that is not mounted on an engine, thread the stud in by hand watching down the head bolt hole, stopping before the stud protrudes into the head bolt hole.
Before installing the compressor bracket. There is a slight interference with the end of the compressor bracket and the head bolt boss.
http://i361.photobucket.com/albums/o...T/IMG_1360.jpg
Trim off ½” on the bracket end.
