Hi,
I had no pressure in my clutch line. I replaced the master and the slave. The slave's cylinder was corroded in place. I put the new slave on and began bleeding the line and cylinders. I was unsuccessful. Upon further examination the rod coming from the new slave went thru the hole in the fork by about .325 in and was stuck. The rod from the new cyl is exactly the same dia. Anyone run into this? The race is this weekend. Removing the trans to weld on the fork is a non starter. I am prepared to grind a sae bolt of a slightly larger diameter but the same length to match, as close as possible, to the original rod's shape as a stop gap. Any other ideas?
Thanks

If I understand correctly, the clutch release fork has a hole in it? Sounds like the overall condition of the release fork is suspect, but I would think you could weld enough to close up the hole as a stopgap.

I suspect if the condition of the fork is bad enough to rust through at the contact point, you'd be better off replacing the fork entirely. You might be able to get away with disconnecting just the transmission if you can move it far enough from the engine to wiggle in a replacement release fork

That's definitely a new one (sounds like the car was stored for some time in damp conditions?)

Bob, it is a hole from manufacturing. It is clear. Perhaps from an earlier part. Have you looked at yours?

Just a thought. I'm sitting at home and don't have a car to look at, but if you can get a mig welder in to the fork area I would tack weld in a washer for a quick fix. Good thick one. Smaller hole then the slave. This will get you buy if you can get a mig gun in there. Also i think I have seen slave rods that have like a little head to them. Skinny shaft to the end which is larger and rounded to pivit in the fork. So you can pull the rod off the slave and have something welded to the end as long as it is rounded to fit into the fork.

There's definitely a hole...

I agree with Bob, if you have someone with skinny hands...

Nope, no corrosion. The hole was emlarged by the rod, probably original equiptment. All fixed - used a bolt ground down to the contours. It will at least get me thru the end of the year before teardown.

Sounds like maybe the strut on the slave is backwards....? The ball end of it should be sitting in the clutch fork.
