Serpentine Belt drive and reverse waterpump for AMC?

What about designing a serpantine belt kit for our AMC V-8's using a majority of conventional parts that are out there. ie tensioner, pulleys and belt? i know its been discussed by the guys in my jeep group, we have pondered it and wished for it for years. Honestly the double pulley will take care of most belt problems but serp is sure slick. I know what originally got this started was about four years ago at a car show in Long beach i saw a Javalin with a Serp setup and then a little over two years agon on the Rubi there was an Orange CJ7 from Iowa who had a Serp setup on his 401. MC thats in your 1/4 of the country were you in on that? :roll:

Also if a serpentine setup were to be considered the WP would have to have a retro kit to convert it to reverse or the belt would require some creative twists 111!!!

Thoughts? :-|

hmm yeah i have alot of guys interested in this and it is on the do list

I helped some guys with an AMC powered hotrod last year that did a serp belt setup. Using the stock waterpump, the pulley was switched for a grooved one (from an Olds fwd I think) and an idler put to the side. I could do a diagram, but I'm lousy at posting them on other sites and getting the links right. (Photobucket didn't like my account. Too much bandwidth for a freebie after the first day!)

Hey Jim, if you will send it to me, I will host it for ya!!

I could be interested in a serp setup too!

A serp belt may look cool, but carry a replacement belt. The belt goes, your water pump and all accessories are offline. I like my old V-belt system on my Jeep. I would have to lose 3 belts before my water pump (and fan) stop, 2 belts before I lose the alternator, and 1 belt for the P/S (which I've driven without before).

Also remember that if you use a reverse water pump, you need a reverse fan and fan clutch if you have one.

Actually I think I like the looks of a serpentine belt more than the function..(sounds pretty lame doesn't it) the aluminum pulleys and stuff.

I think that there was a 304 in a latter model AMC like a spirit or hornet or eagle that had a serpentine belt system. Check it out.

What models and years should a person look for these parts?

NEVER an AMC V-8 with a factory serp belt. Some of the later I-6s did have one.

There was a write up somewhere that someone had done it using Ford pulleys and a small custom spacer, I think. I've seen some aftermarket kits on older GM cars at cruises this summer.

If I remember correctly a while back in carcraft there was a guy that had a serp belt setup. If memory serves me correctly the guy was from Wisconsin I think?

Dudes, and Dudeetts, we need to get some VOTES going ...

After a hot start, we fell OFF the first page already!! :smile:

Gunna take some effort and dedication to get BACK up there!!

Vote now - vote often!!!!

MC needs the hits :t:

If you can make one for a 1974 AMC 360 in a Javelin AMX with A/C & Power Steering, etc., count me in.

An AMC V8 Serpentine Belt System is more than just talk:

Its on! I let Pete loose on grinding the form tools and he has a few things to finish first before he starts to churn out serp pullies. I think we are looking at around 5 different applications for all the accessories people will be using.

Yee haw... dreams come true. :sa:

Any pics or a timeline???

Looks like I'm going to have to do a full rebuild on the waggy :?

BUMP

Looking to do the Wag first . . .

SERP ... SERP ... SERP ... SERP ... SERP ... SERP ...

WHAZZ-UP (with them)??

Coming soon!

Is it my imagination, or is the crank pulley a bit smaller OD than normal?

I think MC said a 20% under drive?

While carrying a replacement belt would be an obvious and good idea, in 20+ years of owning a variety of cars and trucks with serpentine belts, I have YET to have a serpentine belt fly off or break ( even with repeated 6500+ rpm blasts ). I have seen them shred and go from 6 ribs down to 2 or 3, but they have never let me down whereas I have nothing but contempt and disdain for V-belts that are notorious for failure. I personally HAVE had all 3 V-belts come off in one incident. I would be EXTREMELY interested in a serpentine setup for my AMC's

Me too! I'm dying to have a setup like this!

Thought I'd bump this too

winter project is the Waggy motor . . ..

Houston we have machine troubles :(:

Machine probs suck!

I was unable to save the pics of the AMC with Serp setup. We swapped the impeller from a reverse rotation Chev water pump core I had kicking around. The fan and clutch came off a '93 Grand Cherokee I parted along with the PS pump and a few other pieces like the AC Compressor.
I can't get ahold of Dan (not sure where he moved after I switched jobs and he quit driving gas trucks) so I can't get new ones either. I gave him the old harness from a Grand Wagoneer to make it electronic ignition.

For you V Belt proponents, just want to share with you my V Belt woes.
While out performing Christmas Delivery and other hauling duties for friends and family,
the Alternator Fan belt on my full sized GMC Diesel cargo van decided to whine then break.
There is NO way a shadetree mechanic can perform this repair in their driveway in sub freezing temperatures!!
I briefly looked from underneath...too far up to get easily get to.
I might be able to loosen up the alternator, but getting back in place with the proper tension on the belt is gonna be a tough.
I checked to see it all the pulleys still freely rotate...no issues there.

I after charged both the batteries fully (yes dual battery setup) took it and parked it at my local shop.

I had install the belt and perform an oil change.
I got out of there with a bill for $138. ](*,)

The Manager told me his tech really fought hard to get that belt on.
The fan shroud and had to come off and it was a bear.

If I had a serpentine belts, I might could have replaced it in my driveway and saved me time and $$$.
I know 6.5L have serpentine belt setup, so I need to check into this for my 6.2L.

Yee fricking hawwwww new lathe coming in friday!

if it was a two piece shroud it shouldnt have been too bad. You should try changing power steering lines when its -20F ( blew six of em in the driveway in 4 days 111!!! last winter). My buddy's 6.6 duramax had his idler pulley explode on him couple weeks ago and the pulley alone set him back $120 :-|

I just found this thread over here ... a bit newer than the IFSJA.org one ... :lo1l:

This thread has been alive for a very long time but is still updated periodically :?

Pics and pricing very soon!!!

dude. pictures pictures pictures........ oh yeah when is the kit going to work with AC....... i am assuming you will be a 6 groove serp setup? Congrats soon as the geometry is figured out for running with AC then i assume the only change necessary will be the chaning of the ac clutch to the late 1980's york 258 cj serp setup

5 years to the month next month since this thread started

#-o :idea:

Have we REALLY been waiting that long?? Now I'm tossed on whether to put it on the CJ or the Waggy?!?!? 'Course I won't be starting the Wag for a few more weeks :-|

Will the setup work if I have relocated the alternator to the top with your kit? Thanks.

Yes absolutely!

Are you using an idler pulley and if so where is it going. I am currently set up with your billet crank, water pump and alternator pulleys with the alt. relocated up where the AC unit would be using your relocation bracket that has been modified for an Edelbrock MFI intake. I am taking off all of my smog stuff and going without. Have you got any photos of the setup yet?

Please let me know when you start building a kit that includes the A/C. I'll buy it right away...
