M-20 4 Sp

  Is it possible for me to re-build a m-20 in my basement?  Any special secrets to look for? Any special tools needed?  I have it out.  I got a guesstimate for charges at a local shop, he wants about  $1,000.00.  Need to save for the 2011 gathering. Any suggestions?   THANKS

Well first of all......is there anything you can't do? I rebuilt a four speed in my 69 cuda years ago, don't remember it being that hard.

Joel will be the judge on this one.................Here come da Judge

I rebuilt my BW Super T10 last winter and did a lot of research before doing it. Biggest issue was to press the gears on and off the shafts.

Jack, great link

You can do it, Mark!
As mentioned, an good set of snap-ring pliers is a must. A LOT of patience is required to replace the twelve million rollers for the cluster gear. The trick there is to use a lot of assembly lube(Vaseline works great) to get all of them little buggers in there, and then stick the whole thing(cluster gear)) in the freezer for an hour! This will thicken the assembly lube enough to give you time to get it set in the case, align the thrust washers, and slide the countershaft thru the case without all of them dang thing fallin out.
You'll also need a tool to remove the front, input shaft nut...or maybe not. I use a pipe wrench...works just as well as the fancy wrenches they sell.

THANKS, I do not have a press, but several hammers! Snap ring pliers abound. Patience is not a problem, no where to go till spring.  Do not have a T-10, but they must all work about the same.  We are going to open it up and see what it looks like, then make a decision.  Clutch is original from what I can tell, a 11 incher with 26 splines. Guess it will take a little more ponies than I have. Oil is REAL clean and the magnet on the plug is clean as well.  Hope the guts are good.  Later, Mark
