I drove my '64 to the garage today. I have had 2 problems, a) The car pulls hard to the left when braking, and b) I changed the differential ratio to 3.36 but forgot to change the driven speedometer gear to match.
My brake backing plates have no slot to access the adjuster. Everything else is new from "Muscle Car Brakes", their "matrix ceramic shoes, drums, cylinders, springs, etc. I initially adjusted them manually until I could hear/feel the shoes rubbing against the drums. When I re-checked today with the car on a lift I didn't find anything I felt worth changing. I did bleed the brake system again and got a small amount of air from the right front cylinder. I thought that might account for the pull but when finished it still pulls hard left. Any suggestions?
I bought a new driven gear from LIC. After dropping the exhaust system and removing the rear motor mount (with the transmission supported by a jack) I was able to access the speedo cable connection to the transmission. I removed the (new) cable and the retainer clip and pried the gear housing from the tailshaft. Unfortunately the old driven gear did not come out with the housing. After trying to fish it out for 3 hours I finally gave up. I figure the metal gears are harder than the plastic speedo driven gear, so hopefully I won't have a problem with it floating around inside the tail shaft. I inserted the new driven gear into the back end of the gear housing (i.e. The large gear went into the tailshaft first), carefully inserted the housing with driven gear installed into the tailshaft and attached the retainer and the speedo cable. Once everything was back together I drove the car and had no speedometer indication at all. I don't really understand what holds the driven gear in its housing unless it is held in position by the driving gear inside the tail shaft. Since the old driven gear fell out of its housing on disassembly, I'm wondering if the new one also fell out and into the tailshaft when I installed the speedometer cable. The shop manual is no help and I don't have a spare transmission to examine.
When I started the engine this morning there was a loud bang followed by blue / gray smoke from the right exhaust. The smoke cleared after a few seconds and the car drove normally on the way to the garage. After the work described above I started it again and this time there was no "bang" but there was even more smoke, again from only the right exhaust. There seems to be some antifreeze / water drops on the right exhaust extension, so I'm now thinking that either a head gasket or the intake maniflod gasket blew and water is being sucked into the combustion chambers. I hate to think of removing the new FI unit but think that is the only way to locate the problem. Any thoughts?
Thanks, Doug
