<div dir="ltr">Here is another issue that I've learned with my 912 and now my Alpine. I don't know if it applies with the Tiger. <div><br></div><div>The entire clutch system is designed for each piece to work together exactly. When the clutch is depressed to exactly the right place, where the finger springs have gone flat, the clutch plate is fully released. If you go past that point, the fingers actually start pivoting in a way that it cycles back and starts pushing the clutch to close again - even though your foot kept going the same direction. In the 912 (and 356) you can actually feel this point - it's called "over center." You feel the pedal get a tiny bit lighter, then get a bit heavier again. For the 912/356, you adjust the clutch cable to stop just after that point.</div><div><br></div><div>On the Alpine, there are a few people who have reported this happening, and I am having it happen on mine - that is, if I put the clutch pedal in to about 1" from the floor, it shifts smoother than if I put the clutch pedal all the way to the floor. I don't know the exact cause yet. But, it could be from a slightly mismatched clutch master/slave. I have only purchased what was supposed to be direct replacements from SS. So I'm assuming that's not it. Or admittedly, I changed the pivot arm and stand inside my clutch when I swapped in the new tranny (25+ years ago). It was just slightly off. At the time, I didn't think anything of it. But, now, I'm wondering if that "slightly off" was enough to do it. Fortunately, I still have the other stand and arm to put back in one of these days.</div><div><br></div><div>Moral is, be careful with mixing and matching clutch parts!</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Sep 12, 2017 at 12:23 PM, Tom Witt via Tigers <span dir="ltr"><<a href="mailto:tigers@autox.team.net" target="_blank">tigers@autox.team.net</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<div>Richard, I encountered similar when installing the Datsun (Nissan) M/C in
my Tiger which looks very similar to the Subaru M/C. The Datsun M/C was from a
booster car and the receiving end of the piston was not typical (smaller I
believe) to the Tiger pushrod. I scoured self serve yards until I found a
suitable push rod. Unfortunately the rod was from a somewhat rare (today)
Volvo 122. And, the rod capture ring still had to be ground down circularly to
fit the Datsun M/C. But, my recollection (this was 15 years ago) was that the
rod went deep enough to allow the ground capture ring to be held in place
with the clip and the adjustment range worked well with the Tiger pedals.
This is probably not what you want to hear, but as a last resort might be
considered an option. If you look to a universal push rod pay attention to
the piston receiving end size and the capture ring that is designed to retain
the rod with the M/C should it ever detach from the pedal.</div>

<div style="FONT-SIZE:small;TEXT-DECORATION:none;FONT-FAMILY:"Calibri";FONT-WEIGHT:normal;COLOR:#000000;FONT-STYLE:normal;DISPLAY:inline">Hello,<br><br>I'm
trying to install the Subaru dual circuit master cylinder on my Tiger, as was
done in the Classic Motorsports
article:<br><br><a href="https://classicmotorsports.com/project-cars/1965-sunbeam-tiger/systems-of-a-tiger/" target="_blank">https://classicmotorsports.<wbr>com/project-cars/1965-sunbeam-<wbr>tiger/systems-of-a-tiger/</a><br><br>but
the stock Tiger master cylinder pushrod does not work with the Subaru master
cylinder. There is no mention of this problem in the article. I was
wondering if anyone who has performed this conversion has any solutions to this
problem? There does not appear to be a Subaru pushrod available from any
source. Is adapting a universal pushrod the
answer?<br><br>Richard</div></div></div><div id="m_-8415633717301721020DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2"><br>
