Searching google reveals that the bolt is M8 x 1.25 which uses a 12mm wrench. Length is somewhere around 25mm.

 

That's the pitch. Bolts are designated by size (diameter), pitch (coarse or fine threads) and length.

 

Best way to get the right bolt is to either:

A: buy it from a dealer ( expensive, takes time )

B: Pull the bolt that is still there, ( check the other hole's threads while you are there ) then take that bolt to your local hardware store and buy a matching bolt.
Just make sure to get a suitable grade of bolt.

Then put in a new slave cylinder, bolt no with your new bolts, bleed the clutch and then have fun.

 

you guys are the best, thanks

here is the previous owner being an idiot, he probably just neglected to install the top bolt that he was having trouble with. I'm guessing I will run into the same problem of not having enough room to install it correctly :/

 

Well, if the distance between the slave and the fork is now correct and the slave isn't completely compressed to fit, then it would seem he just forgot to put the top bolt in. This would obviouslky bind up and fail. It's a bit of a trick to get the slave compressed while installing, but it can be done...I've done it a few times. If you have the time/money, I'd highly recommend getting a "race" stainless steel clutch line while you're in there. It goes between the slave and the upper hard line and makes installing everything much easier.

 

Can you elaborate on compressing the slave while installing? I'll give you a handful of my negative props if you share one of the tricks

 

it looks like there might already be a stainless line

 

Well, if it currently looks that compressed, the transmission will need to come out as it's not supposed to look like that.

If all is well, like this...


...then it's using two hands and a few words in anger to get it all lined up. It's a matter of getting the rod nipple seated into the fork and getting the bolt holes lined up. It's not really that bad if you are flexable.

 

is there any way to bend transmission piece that the slave rod bumps into? Or, will that mess up the tranny?

 

The angle of your picture shows you should have more then enough room to get a socket and extension to tighten the bolt.

Jack up the passenger side and take the tire off, YOU NEED THAT TOP BOLT....

 

TheDriver, you need to figure out what's going on with the clutch. If that pic you posted from the P.O. is what it currently looks like, it's not right. Dopps' pic is how it should look.

No real trick to installing the slave, it's just kinda a pain in the a$$.

 

how is this not fixed already?

 

lol, the new slave just arrived in the mail yesterday and there was a chit storm brewing outside with rain...I don't have a garage to work out of

 

sorry, it is kind of confusing.

The picture of the broken rubber seal is what it currently looks like. The other picture with the top bolt missing and stainless line was pulled from the previous owners thread which I provided a link to
