Well I'm trying to track down a cooling problem I'm having and decided to replace my under driven march pulleys on the 440 to the stock ones to see if that would help.

Of course I ran into some problems otherwise I would not have wrote this post.

440, alternator, Power steering, was a A/C car in the past. Unknown on the 440 yr model. Has what appears to be a fluid damper and march pulleys. They all line up.

I bought two pulleys from 440 Source. Single v Water pump and double V crank.





The double crank is way off. 2 inches as measure from the first V to the mounting surface vs. 1 and 5/16 I have with the March crank pulley.

The Waterpump appears to be lined up.

Did I order the wrong crank pulley?

Whats up?


Thanks.

These are the pulleys I have.

Apparently 440 Sources' phones are a little busy today I had to leave a message.

I should of asked questions before buying. I assume these motors were pretty much the same.

Maybe my fluidampnr is the wrong one for the motor?

Call Bouchillon Performace

Nothing wrong with those pullies from 440Source, they are correct for a factory damper. You have an aftermarket damper which is much thicker than a stock one.

Thanks

That's what I was leaning towards but because I do not have a stock damper to compare to I'm kind of at a loss if that is what it is.

I've been doing some other research and it looks like March has a 6.5' diameter crank pulley vs. the 5.25" I have now. I just need to make sure it is the same offset. It looks like there is a application with a Fluidamper too so it that maybe the cause. At about $100 it's a bargain considering I just paid the same for the 440 Source pulleys.


Looks like I'll have a set of new pulleys and belts to go with all the other stuff I bought and never will install.

Well it appears these are my choices.

1. Get a stockish balancer and run with that. From 440 Source it is the High Strength Steel Damper - Chrome plated - New. Price: $129.95

2. Get 440 source’s SFI Fluid damper - Chrome - New. Price: $134.95

3. Get the unlisted Pulley from March Performance at ~ $100 plus 2 more belts at another $15 each. I called March directly for help on this as there was no listing that I saw.

Edit: Sorry did not mention the part # for those of you in the future that may run into this problem the part number is 10169 for the 6.5 inch dual V using the old the Fluidampr

4. Get a new updated Fluidampr 720311 with the correct offset at $393.95 and hope I can sell the old one for something.

5. Get the 4 groove pulley from Bouchillon Performace for $145.



Well I hear there are some problems reading the marks outside in the day with chrome balancers so 1 and 2 are out and removing the old Fluidamper from the 440 maybe a issue in the car (well that and the price ) so I think I will go with the March Pulley at ~$100 plus handling and shipping. Well that and another two more belts at $15 each.

I’ll update if this ends up cooling the motor better than the under driven setup.
