I took my trac-loc apart and put a new clutch kit in it, I replaced everything back in the order it was removed, can someone tell me how you check to see how much drag it has in it I put axle in vise and placed unit on axle and tryed to turn by hand but could not budge also put pry bar in hole but could not turn should it be that tight any suggestions ,Mike
You might to use a tire and wheel on the axle as leverage , like checking while in car . I can't remember the torque value, I used to check the break away tension on lockers while we were stock car racing . Sorry
I had the same thing on my Trac-Loc rebuild. I haven't had the car on the road yet, so I'd like to hear the answer, as well.
Hopefully you lubricated the clutches as you were putting them together. Also - something I have done a dozen times in the past was forget to use the axle as an alignment tool as I was reassembling the differential. Once you get it bolted together without using an axle to keep all the clutches aligned its almost impossible to get the axle in it. Sounds like you were able to get your axle in though.
http://www.ringpinion.com/content/book/rebuilding-a-ford-traction-lok.pdf Follow along with this method...Its not the break-away so much as it the spider gear back lash you want .005 to .015 backlash. You add shims to achieve that.
I always soak the clutch material in trans fluid, before assembly. Then use the proper limited slip additive with your gear oil.
Thanks for posting the link. I think the info we need is on page 4-24 which lists the initial break-away torque as 300 lbs ft. and sustained torque as 250 lbs ft.
That's the high limit. Make sure that the clutches were soaked in friction modifier. Notice that we are dealing with one axle locked in a vise and rotating the other axle not the carrier.
I did soaked discs, and after reading replies to my post I realized I was trying to turn just 1 side of diff put both axles in and had drag about 150/200 lbs torque, thanks for replies,Mike
