Why wont my 14 bolt FF gears turn when I tighten the caps?

[afroman006]

I attempted to set up the gears in my 14 bolt today and ran into a snag. I got it all set up and the ring gear backlash was .007 with the caps loose but when I tightened them down, the gears would not turn at all. What gives? I tightened the bolts down to 135 ft./lbs. as the Randy's instruction book recomended. Do I need to set the backlash with the caps tightened all the way down? I'm thinkin about just callin a profesional and see if they will come do it for me. Please help I wanna hurry up and get my /forums/images/graemlins/burb.gif back on the road. Thx

I had the same problem. I put a detroit in the back of my truck... I counted the turns the bolts took to get them out on the caps. When I put them back in... I COULDNT TURN ANYTHING!!!
so I winged it... we will only see in 2 months what happens... /forums/images/graemlins/dunno.gif

The carrier bolts MUST be tightened to spec before you adjust backlash. Remove the pinion support and then add shims to correct backlash.

I assume you counted the turns on the carrier side bearing adjusters and have that set back as it was before?

EXACTLY!!/forums/images/graemlins/thumb.gif Tighten the caps, then adjust backlash. Its easiest to spin the adjusters with the specail tool! /forums/images/graemlins/waytogo.gif

Negative, backlash is set with the carrier adjusters, pinion depth (pattern) is set with shims on the pinion support.

Ok Jason, you caught me on this one. Regardless, the carrier bolts need to be tight before he does anything. /forums/images/graemlins/thumb.gif

Remove those two bolts that hold the little clip that goes into the holes of the adjusting rings, put something small, like a small screwdriver or whatever and turn them, one to loosen and the other to tighten. Snug them up when the backlash it tight and replace the clips and bolts. Easiest rear end to setup i have ever done.
