Torque for jam nuts - MD5
« on: May 22, 2021, 10:09:22 AM »
I am replacing the two bearings in the front housing (nose cone) on an MD5.  I am looking for the torque value for the two jam nuts on the main shaft and pinion shaft.  I need the initial torque for the first nut (to load up the shaft and bearing races) then the final torque for the second nut.  Also, what is the best cleaner to use to prepare for red loctite?  The nuts are 1 1/8", the shaft is 3/4".  thanks

Well, still messing with it.  Deciding on a full rebuild since it is 11 years old.  I have broken 2 pullers trying to remove 5th gear.  Then I called Weddle to ask some questions.  They say that my transmission (MD5) is no longer available.  WTF?  And anything I try to fit in there will have either different mounts, different shift shaft location, possibly bigger to interfere with gas tank, radiator, cutting brakes, etc.  Not happy with that phone call and answer.  More to follow   :nw

.       If I go with a bigger transmission might as well build a 500 horse motor. I did get a call from trans works, they said they can build me one we’ll see.  Glad you got yours all fixed up Dave!

On a side note,since Dart isn't seeing fit to get me a block anytime soon,I will be picking up a second hand SB2.2 Dart Iron Eagle with .927 keyway lifters next week just like I have but a lot more inches. Things are rare as hen's teeth.   Getting a second SB2.2 top end as well from Joe Gibbs Racing. Should be power makers since they are from his last year running the SB2.2 around 2005.  I should get in the neighborhood of 900 at the crank easily and hopefully 700 at the wheel with those heads and 437 inches. Based on the 360 incher I have now that should be doable. This will be a bigger brother clone of the 360. Fun times ahead in October!
