Right angle drives are "FUN "

[trrdster2000]

I’m getting ready to install a “A” type overdrive in my TR6, which is no big deal with a little preparation; three rounds with Hulk Hogan should do it. What got my curiosity was the right angle drive and all the talk of failures and of course that ugly picture of the cable shaft torn all to heck, sticking out of the drive. I had what appears to be one good one, one with the shaft missing and one frozen solid. Lets start with the frozen one, what could I loose. With an assortment of punches I went at it. The small gear was first. a ¼” punch was just right, with a small socket set under it. When you knock out the plugs, there is a raised plug on the inside for the gears to ride on and one had a extra spacer inside, so watch for what comes out. The larger gear turns out to be a bit more problematic if the shaft is still in place. A 3/16” deep well socket ¼” drive works with a ½” socket under it. Unless the shafts are bad, once the plug comes out the gear should push out. The only thing left to get out is the shaft collar and it is driven from the gear end with a 5/32”, you will notice that it is only a press fit to hold it in. How they worked for as long as they do is amazing.
Now we have it all apart except if the cable shaft is an issue, it should punch out or be drilled from it’s shaft. Each gear shaft has a small indentation in the center, designed to hold grease, so lets put it back together with as much grease as we can.
If the cable shaft needs to be replaced, you can use an old speed odometer cable end cut to 1 and ¾”, (no longer, this is very important). You may have to use a screwing effort to get it back into its sleeve, I punched the top of the sleeve and then soldier it and them tap it in from the bottom or gear side. I put the shafts of the gears on a Dremel polishing wheel, just to give them a smooth finish. When all is back together and you have used a punch to secure the plugs, it should turn, even if a bit stiff, because of the grease, a go one will turn in both directions. If it doesn’t turn them you have bent gears and that’s a throw away.

Now, if all this work seems important, it’s not, compared to what you have to do before installing it on the tranny. If you don’t have the washer that fits between the right angle drive and the fitting on the tranny you have just wasted you time if you put it on. The shaft sticks out 1 inch but the square hole is only designed for 7/8 inch and the spacer is needed to let the shaft float and not be in a bind. A washed with a 5/16 hole and the right diameter for the inside will work as long as it is at least 1/8” thick.

I hope this will help someone out or give you something to do on a rainy afternoon, as about all you can do is clean them up and get rid of any grit and old hard grease.
