Part Number of Disk for Centerforce Clutch (-2 ZF)

Chuck,

#260-331 is a McLeod clutch disc.

#260-131 is Pantera specific (McLeod).

John

Thanks, John -

It looked like a McLeod Number. I'm going to call Centerforce tomorrow, and see what they say - I'll post up the results.

Centerforce Clutch Disk for my Pantera

The Centerforce website shows part #387132 for a Pantera clutch disc.

Interesting. I just searched the Centerforce website for 72 Pantera and found it lists the DF021057S part number you mentioned.

Call Centerforce to discuss your application. When I purchased my Centerforce clutch and pressure plate from a Pantera vendor they stripped the part numbers from the box and parts, and fed me a line of BS about how they had Centerforce custom develop the Pantera kit and were the only source for it - and I paid as if that were the case! But when I talked to Centerforce directly, they told me that was nonsense. They rattled off the two possible part numbers that covered my application - one was for a standard duty clutch (which I purchased) that Centerforce maintained was more than capable of handling 400-450HP, and a heavy duty street/strip clutch for more powerful applications.

Garth -

I think that while the Centerforce shows that part as a 1-1/8", 10 Spline Pressure Plate, it is for the Mangusta Transmission (ZF-1).

I will give them a call tomorrow, though. Thanks for checking.

Yes, one of those was for a ZF-1. Call them for the right info. And keep us posted.

Keep in mind that some '71s will take a 1-1/16"-10 spline clutch disc while other '71s thru '74 (and maybe newer) take a 1-1/8"-10 spline disc. So there are 3 choices: a given disc will either not fit at all, or will rattle and shake in use due to excess clearance, or will fit perfectly. This depends on which ZF your Pantera has, and is yet another reason to not 'wrap yourself around an axle' buying slightly cheaper Pantera-specific parts from a clueless parts vendor. I'd call any Pantera vendor to straighten your mess out correctly.

Ah, it's the other way around:

Dash 1: 1-1/8" x 10 spline
Dash 2: 1-1/16" x 10 spline

Clutch for sale on Ebay right now PI Clutch

And yet another... Clutch

Must be clutch day.

Lets try this again

Why is this fighting me??? Clutch 2

Calls to Centerforce say that they don't sell the disks individually, nor do they resurface them.

I am still working on this.

Thanks for the links on the PI Clutch, FP!

I also confirmed John's measurement for the (-2) at 1-1/16", 10 spline.

I bought the Centreforce clutch kit from Summit end of last year part no DF 021057S as listed for Detomaso Pantera. Not sure what the disc part number was if different but just fitted it and I have a problem with release bearing clearance.

When tightening up the bellhousing bolts I can actually see the clutch operating mechanism moving. With the bellhousing tightened up there is no clearance, clutch is engaged.

Having read previous threads on here I just went for the stock release bearing BCA 1625-12.

Whats the problem here, does the bearing carrier need modifying for this clutch setup or how is best to resolve it.

Cheers

Hi Horace -

When I installed my Centerforce clutch, I used a new throwout bearing. It was a McLeod MCL-16525 (T.O. Brg, Adjustable, Pantera).

This bearing has removable collars on the shaft to give you more or less initial engagement. When we assembled my clutch, we used all of the collars, and I never had a problem. Byt this bearing could perhaps help you take out initial engagement.

BUT..... Are you sure your slave and throwout arms are initially in the most relaxed position, with nothing binding, or adjusted to that is provided unwanted preload?

Maybe you should take a look at removing the clutch actuation arm before install, and see if that helps.

Note the rings on the T/O bearing body (carrier). Those can be removed on this bearing.

Here's the T/O Bearing.

There should be no modification required. I have the same setup.

Hi Rocky

Thanks, thats possibly just what I need. How many removable collars are on the bearing and roughly how thick are they.

Have taken off the clutch actuator but its not that causing the issue.

Begs the question why an adjustable bearing is offered for the Pantera, maybe this is more common than first thought.

Gearbox coming off again tomorrow and straight edge and measuring tape coming out to check everything. Will update on what we find but it would be good to know how much clearance might be available removing the collars.

Cheers

It looks like there are two removable collars, each is approx. .215" thick. I just measured it in the housing, so I didn't pull it apart - but that's what it looks like from the pictures.

So it looks like total, you can remove .430" if you need to. Seems like a lot.

Of course, once you take this "preload" out, you need to do a good job of clutch adjustment to make sure you protect your synchros... but that's another thread...


Here's the McLeod Data From Summit...

Summit Racing Part Number:
MCL-16525

Bearing Retainer Diameter:
1.310 in.

Notes:
Adjustable to three different lengths: Position 1= 1.345 in., Position 2= 1.530 in., Position 3= 1.700 in.. Bearing face - 3.000 in.

When I bought my centerforce assembly from Hall it came with a throw out bearing collar that was supposedly different from stock. Bob Byers could probably help you out on this.
