Then some Toploaders had the speedo cable going in from the drivers side, those can use the same cable as the C4
My toploader out of a A code 66 Mustang has the cable going in the drivers side so that had me confused when Jeff posted about right and left gear cuts so that makes sense to me now, also had a different Maverick with a 4 speed that it came in on the drivers side
I didn't say moving cable from right side to left side of the transmission wouldn't effect the direction. If the cable is on the same side with the wrong gear it will sill turn the same direction. And yes you can force fit the wrong rotating gear into the transmission and it will still work for a year or two before you get speedometer jumping back and forth because the plastic gear is wiped clean. Been there, done that. Also the length of the tip of gear will make it or break it. Been there, done that also. C4 gear on left-t5 gear on right.
Now I am going to have to crawl under car and pull mine and see what the gear looks like, I did not have to force it in went smoothly but at lower speeds speedo does jump a little bit and just figured it was due to cable being old and does not happen all the time, this is on my 64 Falcon wagon that originally had a auto and swapped to 4 speed. Easy enough to change gear though
FWIW, my Top loader came from a '70 Boss 302 and the speedometer cable enters the passenger's side whereas the TKO-600 I'm replacing it with enters on the driver's side. Bruce
Ok, but your original post left that impression. The cut of the shaft gear does affect how the cable gear rotates. That's what I was getting at. There are differently canted shaft gears that change cable rotation for the manual transmissions. I think that's where I went wrong in choosing the gear in the Toploader I have now. I think whoever the vendor is needs to specify what gears work with each other, none I looked at when I bought the gears I have now did. Some of the automatic cable gears are different that what you pictured, they had a toothed portion that was about 1-1/2" long
Here are a couple of pictures, Pink drive gear is for driver's side speedo mount and Brown drive gear is for passenger side speedo mount..........notice the cut between the drive gears and how correct speedo gear will be straight up and down inline (with brown drive gear) in 1 st picture. While incorrect speedo gear will be angled sideways as in 2nd picture with pink drive gear, which will chew up the teeth, ruin both drive/speedo gears and eventually break the speedo gear as posted in #18 by Jeff (rthomas771). I don't have a matching speedo gear to post for the Pink driver side, but the cut on it would be opposite of the grey one pictured............. If I recall, the Drive gears come in 6,7,8 & 9 tooth along with various count speedo gears to cover many different rear end gear/tire diameter ratios. David
Back when I was shopping for the drive gear, I read somewhere that these were only in 7 or 8 tooth. The factory cable gears are stamped R or L along with the tooth count. The aftermarket gears are not, least the two I have aren't.
