Wilwood Clutch M/C Part #260-15098

What engagement issues did you have with the McLeod?

Once I had the M/C ready to mount I quickly found out it doesn't match the hole pattern on the pedal box.

Now I'm at the point of either sending the part back and reusing the Wilkinson M/C or drilling out the pedal box and force the Wilwood to fit.

John, rather than modifying the pedal box, just take a round file and carefully “ovalize” the mounting holes on the new M/C. Make sure you enlarge both holes by an equal amount. It doesn’t take much to make it fit.

Wow. Thanks for the heads up. I’m just jumping into the clutch ‘refurb” in the next few weeks.

@davidnunn that's a good idea.  The Wilwood M/C holes are 2.25" center to center and best I could measure was about 2.00" on the pedal box.

Regarding engagement, the clutch had been working fine but someone pointed out that I didn't have enough free play in the slave cylinder.  I adjusted everything back to the recommended settings, slave cylinder rod 3.07" and .107" of free play on the return spring.

It worked ok for about a day and all of the sudden the clutch started releasing when the pedal was completely on the floor.  I've tried adjusting the master cylinder rod/pedal length and slave cylinder throw.  No matter what I try the clutch releases when the pedal is on the floor thus stalling the car.

I hear no sounds from the ZF but now I'm thinking the TB may have an issue.

I can't get enough throw to have the clutch release in the middle or top of the pedal.

Thanks,

John

I noticed the Wilwood MC uses a 3/8-24 fitting which if I'm not mistaken is for 3/16 line.

I ordered .25" hard line to adapt to the existing hard lines on the car.

Just curious what needs to be done to make the MC adapt to the original hard lines?  Would seem that this MC is made for brakes instead of clutches?

Thanks,

John

Try this setup, John. I initially looped the braided line and connected it to the hard line where it comes through. I eventually pulled the hard line below the front trunk where the braided line is now connected. Hope this helps.

@rlee63a4, thank you for the pics!

I purchased a braided line before I saw this and will reflare the hard line fitting to a 7/16 to match my new hose.

Thanks again!

I was able to get the Wilwood Clutch MC installed and working yesterday.  This solved my clutch engagement issue.

Now it makes sense as why the brake fluid was turning dark so quick.

It appears the seal went bad even though it had about 1K miles on it.  I replaced the slave cylinder at the same time so hopefully it doesn't follow the same failure path soon.  It's difficult to tell but I believe some of moisture in the pic below could be water and instead of brake fluid.  I was using DOT 4 which may not resist moisture as well as DOT3 from what I'm told.

As someone pointed out, who knows how long these parts sat on a vendor's shelf before I purchased them.

Thanks for all the help on this!
