Serpentine Belt setup for 218/230??

[kencombs]

Anyone tried to rig such a thing?  I'm planning on power steering for sure and would like A/C as well.  Using a '56 plymouth car engine as a core.  It has the bolt on crankshaft pulley, using a 3/8 belt.  The bolt pattern for that is the same as the A series V/8s.   So I could source a 2 sheave pulley, but that makes the engine longer.  A serpentine setup could drive all those in the same length.  Yeah, I know, it's a puzzle to get all the stuff mounted and also the tensioner/idler required for the serp belt.  But I think overall it would be more compact and they are definitely more efficient, use less HP. 

 

I'm wondering if there are any crank pulleys out there that would bolt on to my dampener/balancer?

 

I will go to a u-pull it place and dig, but any clues would be great.  BTW, I have the A/c compressor, a little Sanyo from a '95 Tracker and will be using a Toyota PS pump which comes with a serpentine pulley and Alternator is no issue at all.  Just that crank pulley that starts it all.

If there is still a full service auto parts store in your area, see if they have a Dorman paper catalog.  The catalogs used to have a section of part # by dimension; that may get you pointed in the right direction for a lower pulley.

Local Orielly's has a few paper books left.  I'll try them.  thanks

From what I’ve seen all the aftermarket serpentine setups are maximum bling with billet brackets, chrome, and clearcoated polished aluminum. And you pay out the nose for all that bling. If you just want it for the space why not get a complete setup at the boneyard off a magnum v8? Even if it needs a trip to the machine shop for re-drilling or some home modifications you’d come out thousands ahead.

Not at all interested in aftermarket, even if it existed.  It'll be home grown or not at all.  I'm really looking to info on what specific parts can be adapted.  Assuming there are no reverse rotation water pumps available (safe assumption I think) that fixes part of the belt routing, (over the pulley, not under on the back side) making most current or recent past factory setups unusable without a lot of changes.  So might as well start from scratch.  I'm sort of fixated on using a Toyota PS pump as it will match my Toy steering gear.  Also the little Tracker AC compressor I have.

Space is at a premium and those belts waste much less power than multiple v belts.

 

The key items here are the crank pulley and idlers/tensioners.  And bracketry of course.  Those will be adapted from something, just don't know what yet.

 

Thanks for the suggestion, I'll certainly be looking at Mopar donors.

Ken, you might be the first one to try this so keep good notes so that you may help others in the future on this endeavor.

 

You may have already thought of this but one thing to keep in mind is your percentage of drive. Say your original crank pulley is 6" in diameter and your water pump pulley is 3" in diameter that is a 2 to 1 drive. So your water pump is turning twice as fast as your crank. This is important for proper cooling same goes for your generator, power steering and A/C to make them work properly.

 

I would think you should be able to adapt a crankshaft pulley and you will most likely have to fabricate all mounting brackets.

Also- it might be way cheaper and easier to sink the rad a little further forward to make room?

Really not sure what you would gain, and the chances of a belt fitting might be difficult as well, almost have to build it around a certain belt, and then make sure you have a spare if it’s not a popular size, and find a tensioner that would work properly as well.  

 

I would go double V belt and run the AC off it’s own dedicated belt and water pump, alt, p/s pump off the other, or could split it up differently
