A while back I contacted Metco Motorpsports to see if the offered a 76mm idler pulley that would be a drop in replacement over the steel/plastic idlers. They offer a 76mm but its for a 6 rib belt setup, it has a 1.10" belt section but the 8 rib section we need is 1.125" minimum. They would probably work but I figured I would ask if they would be interested in making an 8 rib version of the 76mm pulley. I received an email today that in the next run of the 6 rib versions they are looking to run an 8 rib version also. They will be the same specs as the 6 rib, replaceable bearing, hard coat anodized belt surface, etc... Pricing for the 6 rib single bearing runs $64.95, so I would imagine the 8 rib version would be the same price or close.

I am posting this to see who would be interested in possibly purchasing an 8 rib Metco idler pulley. Post up if you are interested.

The 6 rib version can be seen in the link below:

Yes I still am, but I have been in contact with Metco since about May. When they weren't sure if they would make them I went looking elsewhere. I have always liked the Metco design, which is why I bought and modified my tensioner for one of their 90mm pulleys. If they decide not to make them I will pick up the Thump Racing ones.

Good news, Metco has produced a 76mm 8 rib wide version idler pulley for our application. The price was a little higher then expected at $79.99 each, but with the replaceable bearing and hard anodizing they should last a long time. I will be ordering one this week to check for fitment, but shouldn't be a problem. It goes to show vendors are willing to make new products if approached.

Forgot to add the bearing cover and stainless socket head cap screw are not for our application. I will contact them to see if the pulley can be purchased without these items.

The hardcoat is only on the belt drive surface and the rear of the pulley as seen in the pics and stated in the listing. I had a 90mm pulley and it looks exactly the same.

Hrrmm.... here is my current clearance with a Dayco 76mm Pulley.. This one should fit the same, right.....

Yes they are the same OD, 76mm. I am emailing him now to see if there is a price reduction since we can not use the bearing cover and bolt they include (you could probably use the bearing cover if you drilled it to accept the M12 bolt and bought longer pulley bolts, I'll try it when mine comes in), and to see what the pricing is for 10, 20, ect... units in a group purchase.

This is on my to do list... been wanting to do the SC tensioner pulley mod. for awhile now.

There should be no modifications to the tensioner needed, these should be a bolt on piece. No grinding the tensioner body to make room like the 90mm pulley, since all 3 tensioners accept 76mm pullies.

Maybe they will want to make a cover and source a bolt for our configuration.

I called and spoke with Rick at Metco today and have some answers to a few questions.

- There are no group purchases direct from Metco since they are the manufacturer and can not compete the price with their distributors. If we want to do a group purchase it would have to be thru one of their distributors which are listed. http://www.metcomotorsports.com/distributors.htm

- Bearing cap- The bearing cap that comes with the pulley is for an M8 socket head cap screw. He said the modifications needed to fit an M12 SHCS that would be needed for our application could easily be done in someone's garage, but he also said he would quote a price on what they would charge to do it.

I have already placed an order and will post pictures of the tensioner and bearing cap modifications needed.

Just spoke with a vendor near me. He is going to get us prices on 10 quantity and 20 quantity.

He is supposed to get back with me by Monday. I have him the M12 SCHS as the part number. That was what I understood it to be. Let you all know what the prices are when they come in.

Thanks for all the work on this!!

rzimmerl
08-13-2010, 12:13 PM
There is no special part number for the M12 for our application. I am sending Rick from Metco the fastener we will use and he will modify it accordingly, since these will be one off pieces. The length of the bolt still needs to be calculated, when I get all the pieces in and am able to reverse engineer it.


---- If we do a group purchase on these, we will have to send Rick the exact same fastener for all the pulleys sold, as the dimensions between bolt manufacturers can be different and cause tolerance issues. This was requested by Rick based on their experience of using fasteners.

If anyone gets a GP started feel free to have them contact me as to what I have already worked out with Rick at Metco.

I gave Jeff (my vendor) Ricks name and the M12 as a number. Hoping they get it figured out from there.

Its basically going to be the MIP-76W pulley with a modified bearing cover to fit an M12 socket head cap screw instead of the M8 socket head cap screw they are designed for.

FYI TO ALL: Do not order the Metco 76mm pulley at this time. I received mine today and after a quick mock up the backspacing of the pulley is not right. The stock pulleys have a 12mm backspace from pulley edge to the where the bearing mounts on the tensioner arm and the Metco 76mm pulleys have a 6mm backspace which means the belt will be hanging off as the pulley is pushed out towards the radiator. The 90mm pulleys have the correct backspace and work perfect, and Metco lists them as the same dimensions but they are not. I will be calling Metco on Monday to see why they are different then they list.

Recieved an email from Rick this morning. The 8 rib 76mm pulley design was based off of the pulley designed for the 3V 4.6, which has a different backspace then the 90mm 03-04 Cobra idlers. He is letting me return my pulley and in the next batch they run, they will machine a set with the Cobra 90mm backspace. I'll update this thread when I recieve any more information.

I'll email Metco and see when they think they will run the next batch, which will include the custom 76mm pulley we want.

Looks like they have updated the site stating that the MIP-76W is coming shortly with the same backspace as the Cobra 90-100mm pullies.

Not sure if you are going to organize a group buy, but if these pulleys will be a direct replacement for the blower and jackshaft tensioners, I'm in for two. I have the 90mm Metco on the main serpentine and really want something to match it.

rzimmerl
10-08-2010, 12:05 PM
Yes a Group Buy will try to get organized for these. These will look exactly the same as the 90mm but are a drop in replacement for stock pulleys. I was just thinking about these this morning, I'll send Rick an email see if he has any updates production time.

The description says they will be made soon with the offset that will work for us.

After reading this thread, I'd be interested in a set of pulleys. Earlier there's a mention of 90 mm pulley. Which pulley can be replaced with the 90 and what model number is it in on the Metco site?

People ususally put the 90mm Metco up by the alternator. I've got one in this pic:

http://www.sccoa.com/forums/garage_attachment.php?id=1474&attach_type=full

It was a 90mm pulley for a Lightning, but I'm pretty sure the 03-04 Cobras use this same pulley too. Only mod that you have to do is when you remove your stock pulley, you have to grind a very small 1/8th inch lip away from the tensioner.

Now that I think about it, I'm pretty sure this pulley won't work with underdrives + AC system still in place. Not even sure if it'll clear without underdrives.

rzimmerl
06-08-2011, 10:40 AM
The bolts and covers are for a Mustang application, you can use the stock tensioner pulley bolt without the fancy cover and it will bolt right in. If you want to use the cover it will have to be drilled larger for the M12 bolt which can easily be done with a hand drill.

06-08-2011, 11:01 AM
Metco does not offer a Group Purchase discount when going direct, and I know someone has contacted a Metco distributor that was local to them on a GP. If everyone here is still interested I'll start a GP thread, and someone can take over the buy with a distributor. I am to busy at this time to handle another one if someone wants to take the lead on it.

This should work for all three, but was primarily for the jackshaft and supercharger tensioners as they are smooth pulleys.

Just a heads up, as is typical with any manufacture/vendor relationship - parts are cheaper if you purchase at a vendor.

These pulleys are $80 on Metco's site, but $60 if you buy them from Livernois:
