So I'm test-fitting my engine and transmission in the car right now, and I'm having some problems. Perhaps someone can offer some advice.
Engine is a 2.7 liter, transmission is a 901 pull clutch, mount (for now) is a Patrick Motorsport piece. Issue #1: supposedly the clutch cable to use is a 72-74 911 unit. The sheath is a little short, though, and making a bracket isn't necessarily easy because part of the crankcase prevents me from having a straight shot. I have an idea of how to do this, but I'm wondering if anyone's done this before. Here's a pic: Attached image(s) |

QUOTE I suppose you have bigger six bolt CV joints (outer diameter 100mm) if you have drive flanges from a sportomatic. So, you have to use 911 axles also.... Do you ?? I'll try to answer this as best as I can. Everything from the flanges to the hubs is 911. I'm using the large CVs, as found on '69-'71 911s. Basically, these are the same size as turbo CVs. Whereas turbos use 6 bolts to attach the CVs to the flanges (I think), I'm running the 4 10mm bolts and two rollpins, as the '69-'71 911s did. This conversion is kind of being done on the cheap, using parts I have access to and can cobble together. Here's how the axles worked out: shafts are the longer '72-'73 911 units CVs and boots are used '69-'71 911 units, cleaned, re-packed, and installed on the '72-'73 shafts. Drive flanges (transmission side) are from a Sportomatic transmission of the same period. Stub axles and hubs are again from a '69-'71 911. I'm using 914-6 rotors and 914-4 calipers. Hope that helps. I am concerned that at least on one side, with the wheels unsprung, I can grab the shaft and not be able to move it back and forth. I wonder whether I need to have any play at this extreme of the suspension travel. |
