^ I had to do that for a week before. I know my starter was hating it because I left my pedal at the floor (because my clutch master cylinder and slave cylinder died) and when I was forced to stop at traffic lights and I couldn't coast long enough from far away, I would shut it off and then when I had to go, I would keep it in 1st and crank it over and give it gas and off I went. The rest was all speed shifting, which I good at real fast. My car was my only mode of transportation and I had to work. I was also waiting for the parts to come in.

After searching I saw this thread and thought I might update it with an picture to show my experience as well!
It broke just like "wan" had described. Except I loaded it on a trailer instead of driving it back :-)
A $3.50 part has my part broke down for two days until the part comes in courtesy of Ray at Malloy Mazda. Actually the shipping was more than twice as much as the part itself.

Did you read the rest of the thread? This will happen again shortly if your bushing is defunct and the clutch pedal is worn as described previously. You need to fix the root cause, not just the result!

I got home by floating the gears and timing the stop lights by driving real slow up to them crossing my fingers they would get green before I reached them. I was on the freeway most of the way which wasnt a big deal but I did end up running one red light right as I got home, good thing I was the only car on the road at about 3 am, and coasted up my driveway with the engine off. Going up the driveway was the scariest part since I only had so much room to get in and brake before smashing into the house without power steering or the brake booster helping me

I did read the rest of the thread, but I had already ordered the part while the car was still on the side of the road and I was waiting for the trailer. I'll look more closely tomorrow and check the remaining part of the clutch assembly.

Ha, yeah it must be a conspiracy! Your FD looks amazing and an all black interior is what I'm shooting for as well... I wonder how many of ours with the same color and package there are?

My clutch pedal started to get sticky at about 140,000mi or so. Upon inspection, I too found a broken bushing and elongated hole.
My solution was to bore the lever and press in a roller bearing. Before you flame me, I considered the stresses in the beam and concluded that this would work fine.
Putting a real bearing here substantially reduces friction and has transformed the feel of the clutch, it makes the plate feel lighter and it is much easier to modulate. One of the best mods I have made to the driving feel and enjoyment of the car.
In so far as reliability is concerned, I did this mod 6 years ago and have put 50,000miles of daily use on it with lots of stop & go; most of those miles with a heavy ACT EXTREME pressure plate installed (and a reinforced clutch fork). No problems.

I always wondered how you did that. Thanks for the pics.
This is now linked to in the FAQ thread.

A few questions about this mod in the effort to save time...
1. Did you buy a replacement pin or bushing to go back in the bearing?
2. What size of roller bearing did you purchase?
3. How much would you charge with shipping in order to do this?
Thanks man!

1) No, I used the existing pin as it was undamaged. It properly fits the ID of the bearing with no bushing required;
2) I don't recall the exact size off the top of my head. It is a metric size, as most
bearings are, it fits the pin in the ID and the width of the brake pedal; the od is de minimis;
3) I estimate the cost of the service at about $65 to $75, including bearing and return shipping (shipping is based on a medium-sized domestic USPS priority mail flat rate box) Maybe a little less if there is enough interest.
Additionally, I will estimate turnaround as 2 to 3 days from reciept at the standard price. It will be more if you want same day/rush service and/or overnite shipping. I think this is reasonable. And you'll like the result.
A note of warning: If you attempt to do this yourself and you oversize the hole--by even a small amount, it will eventually result in a fatigue failure due to constant flexing over time. This mod depends on the bearing to provide structure to the beam section (removed by boring) while it is under compression. Conversely, the bearing cannot be pressed in too tight as the back side of beam is thin and could easily be split.
The way this operation will be performed is by boring (not drilling) the lever in a mill fixture to properly locate the bore, sizing the hole for a very light press fit and fixing the bearing. Pin location remains stock.
Hope this helps.

If I may, I would like to suggest an alternate fix:
Use a "DU" bushing for the repair - these are used in many racing applications and have extremely long life, high load capacity, very low friction, small OD, and are inexpensive, while requiring less hogging out of the pedal. They are available at almost any bearing-supply house. For instance, Applied industrial Technology ( http://www.appliedindustrial.com/ ) has them.
1. Size the "DU" bushing (steel outside, layer of porous bronze inside that, and Teflon/lead layer inside that) to be the proper ID and width to fit the pedal arm and the pin.
2. Machine a spacer to fit the OD of the DU bushing (they are quite thin-walled) to make the OD match the hole you want (as small a possible while having a circular hole) in the pedal.
The advantages are price and smaller hole in the pedal. If i need to repair mine, that is what I will do.

Well I got the part in the other day and after a few days of driving around; the clutch feels sooooooo much better! It makes my pettit rally pressure plate feel almost like stock now. The shifts are very much improved, especially 3rd gear. The whole thing just works and I shouldn't have any troubles with the new setup!
I picked up the bearing at a local bearing and transmission shop. It's from a company called "Peer Bearing" and their part number is "608-ZZ-C3" It's labeled dimensions are "8x22x27, shielded"

Looks like Grainger carries that bearing too...and it lists all the specs including load capacity. http://www.grainger.com/Grainger/items/1L001
Was the ID a good match?
