These bolts torqued to 120 Ft Lbs.
Torque to 135 Ft Lbs
Finally 20 Ft Lbs, or more likely 240 inch lbs.
When you have everything torqued down, except the adjuster nuts, tighten up the left side adjuster until there is little play, then tighten the right side snug and check with a dial indicator. My initial adjustment was .011. and finished adj was .007, which is about the middle. The adjuster nuts need to be adjusted so that the keepers will fit in the holes, so there is a little fiddling, but all in all one of the easiest third members I have ever worked on
Here it is all right and tight. Very smooth and quiet. Yes I could have a few thou less backlash, but will see how this feels. Incidentally the original backlash was .022. I also checked the gear pattern both power and coast sides, and the pics just didn't show up well, but excellent full tooth pattern right in the middle.
Lastly before I move on to the brakes, here is a picture of a Strange S/S Dana 60 35 spline axle for the ol' 54 chevy drag truck, (Ol' Heavy type but turbo 362 ci LQ4 motor with Borg Warner 465 turbo) just for comparison. Dana on the left, 14 bolt on the right. Strange said I should be able to put 1500 hp to this axle before it breaks. No wonder the 14 bolt is so beloved.
Got a few parts I lost, a hardware kit, some bolts, wheel cylinder, so everything to assemble the right side brakes. I assemble them on the bench, then bolt them to the rearend. Getting excited as I have been working pretty steady and have been making some visible difference. I hope it's a little fast.....there is always low range! Probably take a break, as we have a big family farm fourth of July, Jay's not here, gotta be a Washingtonian to get that one. Have a happy fourth, post square pics!
Hi Craig. I was just poking a little. TrueTrac has nicer street manners. If you are going rock crawling or mudding that Detroit Locker is the best choice!
Ha Turbo4whl! Here are a few pics why I want a very good off road truck. No wonder my dog is panting! Our ranch is 230 acres pretty steep, you can see part of the house lower right. I hope to get the 14 in the truck today, though I may be doing some wiring in the machine ship, to hook my Bridgeport and Lathe...etc.
Well got the K20 all together, and looks good with new rear brakes, (front next) all painted up. Took for a test drive....not to auspicious. Back to the ranch. Outer bearings both came apart, had to cut one inner bearing to get it off the shaft, so will replace all the bearings, poo! I think I installed the outer bearing backwards....need a schematic.
Did you make sure to install the retainer (It happens)? There are 2 styles. The clip style or the lock washer that fits between the spindle nuts.
Thanks Craig85. Yes I did use the retainer. Pulled it apart this morning, and both outside bearing had fallen apart. Had to cut the inside bearing on one side as I needed to get the seal which also toasted the seal. To town and bought bearings, (in and out, with races), and had the seals. 188.00 learning experience. I believe I installed the outer bearing 180 off or backwards. Looking for a schematic of the hub assembly, so far have not found anything, but just started looking.
Nice work on the truck!
Thanks Catbox!! Ok, I need some help. This is how the bearings were installed in the hub. I placed them on the axle to help me better visualize the assembly.
I think the inboard bearing is installed correctly and the outboard bearing is backwards. Craig85 I think had a assembly pic, and this does not look right
