    sm465/d20

    i put the top back on the tranny and bolted the adapter up to the back of the case

    here's the problem

    when i tighten the adapter to the back of the tranny, it causes something to bind, but if i loosen it up just a little then everything turns fine, its not loosened up enough to have any play, but still not real tight

    any ideas as to what the problem could be or should i just put some locktite on the bolts and tighten up to where it doesn't bind?

    dang fool, I forgot all about it....your prolly gonna need a different output gear, your teeth are pitched at a 17.5* angle and the one you need is at like a 20.1*. There is a place in Oklahoma where i ordered mine from but if you get lucky our friend from down south might have one. I found all the info about the gears online and I think on the advanced website has it to. But in the mein time you can still bolt it all up without the gear and fab your mounts while your waiting for the new gear. I think it cost like 30 bones for the stuff. Ill look up the stuff to, i just dont have a lot of time right now.

    landon i had the same problem with mine because I assembled it dry

    oil the **** out of it, especially the synchro's

    I dont think the bull gear has anything to do with it, the degree of the tooth cut depends on what degree the t-case was cut for.

    I would almost suck your weiner if I could borrow that adapter plate to get all the dimensions from it, but I know you are putting it in soon. Anyone else have one laying around??

    the adapter wouldn't be very hard to make if you had a machine shop, but the mainshaft you have to replace in the tranny would be a lot more difficult, thats why i bought it

    How much did it cost you to get the shaft made? I'm trying to mount 2 sm265's together. I know, I'm gay. Anyways, it would be alot easier to just copy the back of that adapter. Thats why I was asking!

    doug, the factory sm465 bearing retainer will have the same bolt pattern, just use that. the only thing it won't have is the holes for the dana 20 and you won't need those
