Adding Classic Air firewall forward kit... belts?

[BrianShaughnessy]

After I dunno how long I finally opened the boxes up on the Classic Air AC kit I've had in the basement for awhile...  and then I quickly lost an ambition when the temps hit 90.    Sooooooooooo....

  I've seen several pics of folks adding a Sanden compressor and then adding march serpentine pulleys which looks totally awesome.

   All I want to do is just use the kit steel pulleys and regular belts for now.   So the new setup would run 2 standard belts from crank to compressor and alternator.    Power steering to water pump to crank looks the same single belt.   Once you start changing WP and crank pulleys you're committed...  easier said than done in a 2 bit town where I usually have to order belts.

    If anyone has done this...  what size compressor / alt belts did you use???       Thanks!

My Classic kit came with an "Add on pulley" for the crank. It only adds one belt that drives the compressor.

My classic Air kit also came with the Add on pulley for the A/C.  (yellow arrow on the bottom) and a idler pulley (yellow arrow on the top) as well.  One small belt will work with this as it will go on the crank, idler and the compressor.  In my picture, the belt is not installed yet.

Yup that's like mine, for a 440.

Not quite the same as what I got...     I got a 2 belt pulley compressor,  along with a different WP pulley and a 4 belt crank pulley.    No add-on pulley.    By the destructions...  looks like the inner 2 belts will run off the crank to the compressor and then the alternator.   Then 1 belt for PS and WP...  and an empty on the crank and WP.   .

Here's a crap pic of the destructions...   my scanner is DOA due to ink issues today :/    Having a hard time getting withing size limits.

That is stock '74 400 engine with a/c configuration.

That belt config is also the correct stock way they run on a '69 440...

All 4 slots are utilised on the crank pulley. Inner 2 run the alt/ac, 3rd one goes straight to the p/s pump, 4th one goes to water pump and the tensioner pulley. You have to have the correct mounting bracket for the sanden a/c pump though in order to use it with the original pulley setup configuration.

I should have known you'd make sure the belts were perfectly lined up

Kit didn't include tensioner

Brian, I recently just finished installing a Classic A/C kit in my '68 Charger. My kit also came with the Sanden compressor with 2-groove pulley, and the add-on crank pulley which I didn't want to use.
I installed everything using the stock A/C pulley setup.

I got the idler kit off eBay from Vans, came with the alternator brackets and everything as a kit:

The compressor brackets were supplied by Classic from Bouchillion, they will differ depending on which water pump housing you have. I needed the kit for an aluminum water pump housing. Check their website for the 2 kits, this one was #4710:
https://www.bouchillonperformance.com/inc/sdetail/467/569

So the only 2 parts I had to source were the water pump pulley and the 4-groove crank pulley. A great member on here hooked me up with those, a nice set of used ones. 

I could not find smooth-type, stock appearing belts without spending a fortune for Quanta repro belts, and I didn't really need those belts for this car. So I got belts from the local auto parts store, smooth top and serrated bottoms. Belts were all same as factory stock length:
A/C: Duralast 15600, need 2.
Water pump: Duralast 15360
Power steering: Drive Rite 15423DR (the Duralast belt was too wide to sit properly in the pulley, this one fit perfectly)

Hope that helps!

Thanks Bill....  You da Mann!!!       
   
   Gonna rip it apart later this week.

[BrianShaughnessy]

So I started ripping it apart..
 
And I had to order the 4710 bracket for the aluminum WP housing and the Van's alternator mount kit...     There goes another $320 on this project!!!

Having A/C is priceless. Guys I didn't even know noticed my windows up and asked about it.  Florida is HOT!
