Help! Crank Pulley too far forward /w ATI super damper - 05/31/09 12:24 AM

I just bolted up the water pump and crank pulleys, and the crank pulley is too far forward.
I am pretty sure this is because of the ATI Super damper?

Anyone have a source for crank pulleys that work with the ATI damper? The pulleys I currently have are the March Underdrive 4-Belt pulleys for an A/C and P/S car. It really don't want to try correcting brackets for all those accessories!

Might need the 3/8 Water Pump spacers which is common for a lot of aftermarket Dampeners. The WP accessory bolts will typically bring the other accessories (ps pump/alt) into line.

Which Damper mdid you get? What type of Timing cover do you have? When I had my Indy Cover on my Engine I ordered the wrong damper and a call to ATI got me a replacement which let my pullys line up without any crazy shims or spacers...just saying...

They have four or five different length Mopar hubs.

Hope this helps or it's cutting time!

I ordered the March pulleys designed for the FluidDamper. I think these will work?
I should have them in a few days....

Just got back in town....
Bad news, They still don't fit, but now the crank pulley is only about 3/8" too close to the inside?
Anyone make a 3/8" spacer for the crank pulley?

Also, found out my 727 trans has the '70 and earlier stator support (and front pump) and dosen't fit the new TSC front drum with the wide bushing....

Mancini Racing has crankshaft pulley spacers.

I have the ATI damper with SB chevy bolt pattern for the pulley, I still had to do some shimming to make it line up (4 3/8 inch washers for each of the 3 bolts worked just fine). I originally got talked into the chevy pulley pattern because SBC pulleys are cheap and plentiful...but it ended up nothing but a pain in the...

Thanks Andy, Mancini sells a billet 3/8" crank spacer. I just had to order longer pulley bolts...

More project setbacks, I was inspecting the 727 trans, and noticed I had broken a few teeth off the front gear splines

Are there any special discount deals on the steel front 727 Gears? I looked at Cope Racing, and they list for around $400? and the hardened output shaft is $675..
I guess I need to start working overtime.

451. Same exact problem here, so I'm trying to get a lead on this as it is keeping me from firing up my new motor. I have the underdrive March pulleys also that I ran with the Fluid Damper with no issues. They are the single V-belt types. My crank pulley also sits in about 3/8 of an inch.

Re: Update: Crank Pulley too far forward - 06/23/09 03:20 AM

How did you balance that pulley after the cutting and welding?

Like I said, I have the same problem with my under drive March crank pulley combined with the ATI #19122E Super Damper.
My bottom crank pulley sits in about 3/8 of an inch or so compared to the upper water pump pulley.
I just ordered the Mancini # AR1340 billet spacer and it should be in my hands in a few days. The dimensions are 0.375 thick which narrows out to about 3/8 of an inch.
I'll slap it on as soon as I get it and let y'all know the results.

By the way, the ATI Super Damper is lighter then the Fluid Damper.

Re: Help! Crank Pulley too far forward /w ATI super da - 06/24/09 08:14 AM

I got the spacer from Mancinni today and the pulleys all line up now

Now I am waiting for the 1-1/2" long ARP bolts to come in so I can bolt it all up. Of course, the way this project is going the spark plug wires I ordered (and specifically mentioned they were for a stock type distrubitor cap) came in and were for a HEI type cap

My next project is to make a bracket to mount my 130 Amp Denso alternator next to the right side of the thermostat housing.
I will have to take some pictures of the pulleys and alternator mounting..

What is the ARP bolts part number so that I may order them also?
I was going to dig in my misc. box of bolts, but figured that this calls for some good high grade hardware which I may not have in that length.

Visually regretful, I am running a GM 200 amp 1 wire alternator which has served my purpose for some time now. When Mopar creates a 200 amp 1 wire, I'll switch over again.

Here are some pictures:
ARP stainless 12-point 5/16" x 18 tpi, 1.50" long.
they are a bit long, but I figured it would be easier to grind a bit off than use bolts that are too short. I measured the depth of the bolt surface on the pulley to the timing chain cover using my vernier calipers and the distance was around 1.625" so there should be no problem, and when I add the washer (or two) under the bolt head there should be plenty of clearance for the timing chain cover. The ARP part number is 612-1500. I just with they sold them in six packs, I had to buy two cards with 5 bolts each.

Picture of Mancini spacer on March Pulley.
The pulley is the one march specifies for the fluid damper. This is a nice spacer, it fits great and is machined to center on the damper hub, and has its own hub lip for the pulley to center on:

Pulley alignment. It looks like I may need a shim for the water pump pulley, but the alignment is pretty good. You get the general idea of where I am intending to mount the Denso alternator....

Gammm. Are you a news correspondent 451? That was one of the most detailed answers I've seen yet. LOL. Thank you.
I just found out that a company named DMI produces Aluminum crank pulleys with sizes that may serve us.
My Mancini spacer is already on the road to me any how.

That amount of inbalance is never going to show up. I did the same thing on my 340 with a fluid damper. I have a torque converter shop and have the gear to do it. If you were real paranoid about the balance after welding you turn the weld itself down.

Mancini Racing also has the water pump pulley shims in stock.

Glad you like the crank spacer, thanks for the business.

Andy. I didn't know you were making them. Glad I can put a little money into your hands and the Detroit economy, even if its small snippets here and there.

Just received my crank pulley billet spacer from Mancini and all went together flawlessly. All the drive, water and alternator pulleys are aligned like the stars now. Getting close to fire up.
