I've seen an '84 year car that ran a race clutch for only a few races in '85. The pedal was worn oval, but the pin was fine. It seems to me that just drilling the pedal isn't enough. It needs a strong bushing to make it last.
Most of us have stiff clutches that need something stronger than a cast pedal.

If you look at the pics i posted of my nissan's clutch pedal, there is a metal sleeve that is pressed into the hole through the pedal arm
looking into that for our pedal- part of the modification fix i'm working on

6 stock replacement pins ready to go ($10 each)

I have 1 upsized pin made, cant test fit without a pedal.  seems there is plenty of meat to drill out on the master and the pedal itself.  
I may try to find a standard size thats less of an extreme difference than one size up metric- but then it depends how far you need to drill to get rid of ovaled holes

its certainly part of the problem, but the pin and master cylinder are the easiest worn parts to change.

fixing the pedal issue would mean drilling an upsized hole through the pedal arm and clutch cylinder- then using a larger clevis pin
a kit which i am working on logistics for.  
it would require you to send me your clutch pedal assembly - i would drill the pedal, install a new clutch master (or re-use yours if you want), then make the upsized pin to fit it.

If there is interest in such a service i will make it happen - perhaps solving floppy clutches once and for all

I would be down if you make a larger size clevis pin that can be used with an off the shelf teflon coated bearing that could be pressed in.

You can even sell the entire kit, just add 12mm drill bit. (maybe a 1/2" will work, bearing looks adjustable)

The linked bearing is 12mm in length, and has no flange (will fall out)
also, only lists OD, ID not listed

Need to find one with a 12mm (or 11mm) OD and a 10mm ID so the stock pin size can be kept, with a flange, and a length of 3-5 mm
It has to be short enough to put one through the pedal, and have one in each side of the clutch master
I welcome help finding such a part, since I've had no luck thus far.


In the meantime, i have stock replacements that are polished hardened steel, which will get rid of some slop and prevent further wear.
still $10 each --(a pin you will need to replace even if you decide to upgrade with bearings)--

I also have upsized pins that require drilling to M12 through the pedal and clutch master.
Having a pin with a hardened, machined, and polished surface should take care of most of the wear issues
Upsized pins are $15 each (parts to make are more expensive)

Ordering info in the first post

that one was just an example of what can be used, and sold as a kit.

issue is finding the part for the job - ive come up with nothing closer after hours of searching online
is the consensus that the majority is only interested if the bearing route is pursued?

I think the pin is great!
It just doesn't address the problem of the holes in the master and pedal getting egged out.
Something like this Machined down to a little more than the width of the master and the arm drilled to a press pit for them
http://www.mcmaster....earings/=v0rpj1
Another sleeve pressed in the clutch pedal like this guy.
http://www.mcmaster....6679k14/=v0rshn

Then use your pin in it. When a bushing starts to wear you can just replace it. That is what I have planned to do for years.
Other projects just seem more important ... all the time lol

I have hunted around for bearings before too and it's tough to find something with a workable OD unless you go with a needle bearing and then use a smaller pin.
Taking too much material out of the clutch arm could make it weak and possibly bend/break so the best bet may be to go with a smaller pin. Say 8mm and then you wouldn't have to take so much material off the pedal arm.

M11 might not be enough to get rid of the "egged" holes, 1 or 2 mm wont make a difference, pedal has plenty of meat

I'll hit up my machine hardware shop this week, searching online is fruitless if you don't know exactly what to search for

I will find or order a bunch of bearings to figure out something that works-
a spare clutch pedal + clutch master would be great if someone's got one

found one that will work
just ordered a bunch to test them out

bearings on the way gentlemen, only have to drill to M12 and will retain stock m10 pin size

lets make this happen so sloppy clutches are a thing of the past

sent yesterday, questsale.

Bearings still on their way to me,
How do you prefer the kit to be sold? as a DIY kit with a drill bit? or mail your pedal to me and I drill + put it together then send it back

A note from the producer:

I know this bearing will still have the clutch pedal and master on the same rotating surface but it is a replaceable sleeve,
This bearing should take the abuse and be easily replaced.

I will order some flanged bearings, cut them short, and have the flange against the clutch pedal and pointed outwards on each side of the master, so each component is rotating with its own bearing against the pin.  however, the sleeve pin will have to be cut short enough to fit between the two, i see many hours cutting these things with a hobby saw in my future.

I need to make some sales before any further development,
(this batch of bearings cost me $30... small batches are WAY more expensive than buying by the 1000's)

Even with the later developed product, the same pin will be used (swap to my stock pin now and be ready to updrill + get rid of slop for good later!)
the same M12 OD will be used (upgrade with the current sleeve bearing setup now and be ready to upgrade to a setup with a bearing on each arm.


Point is- i need to know if there's interest or not, so put your money where your mouth is, and vote with your cash
I need to recoup losses before spending more to continue improvements

Thanks for your interest, suggestions, and patronage.
-Aaron

As of now i offer two options to fix your clutch pedal slop

Stock size replacement pin $15  (no modification needed)
Stock size replacement pin with bearing $20 (requires drilling pedal & clutch master arm to M12)

This sleeve bearing will upsize the stock pin to fit a drilled up pedal + master cylinder.
when wear becomes present on the sleeve, you can replace it

(please forgive price change, I was losing money at $10)

I would include a drill bit, if it needs to be pressed in, it would need to be a metric drill bit, and those are difficult to find. If you can buy a few in bulk, I would pay extra for one.
