Re: HELP! How do you install the clutch slave cylinder on a F350?
I was interrupted in my previous reply, so now I have time to finish.
All new master cylinders are not alike. The problem masters seem to have a longer rod than the original master cylinder. One way that I have seen to cure this problem, and I did it on mine, is to space the new master away from the firewall. The dimensions required seem to vary, but .200" should work, or 3/16" if you don't have a mike handy. One member used 1/4" plate and got it to work.
There is a plate that is glued to the fire wall with a butyl compound that can be removed. Washers can then be glued down and the plate set over the washers. Use some RTV to fill the gap and your firewall won't leak.
The risk of not having the spacing correct on the new master cylinder rod eye is to constantly have a preload on the clutch release, just like riding the clutch pedal, and having the clutch slip when under a load. Several member have burned up their new Luk or SBC within a very short time of installation.
