9" Ford specs
 

Could someone help me with torque specs on a 9" Ford center section to rearend housing? Ready to install, just need torque specs.
Thanks

Well you didn't say what third member that you have(stock,aftermarket iron, or aluminum) so here is what I have. This is straight from Richmond Gears instructions that came with my Pro gear set.

7/16" Ring Gear Bolts : 60-65 ft/lbs
1/2" Ring Gear Bolts : 100-110 ft/lbs.

7/16" Carrier Cap Bolts : 60-65 ft/lbs.
1/2" Carrier Cap Bolts : 80-85 ft/lbs.

Here are the specs from Mark Williams for their aluminum center sections

Standard Pinion Nut : 110-125 ft/lbs (max : 175 ft/lbs.)
Large Pinion Nut : 140-170 ft/lbs. (max : 200 ft/lbs.)

3/8" Pinion Housing Nuts : 30-35 ft/lbs.
7/16" Pinion Nuts : 40-45 ft/lbs.

1/2" Carrier Cap Bolts : 70-75 ft/lbs.


Now here are the torque specs that I have with my Mark Williams aluminum thru bolt 9 1/2" center section (MW PN # 57448-95S) set up sheet. I'm using a 9" ring & pinion in it.

1/2" Ring Gear Bolts : 110 ft/lbs.

Carrier Bolts : 90 ft/lbs.

7/16" Pinion Nuts : 45 ft/lbs.

Large Pinion Nut : 160 ft/lbs.

Sorry, it's a Strange aluminum center section.
Competition Engineering sheet metal housing w/ 3/8" studs.
Thanks again.

45 ft lbs should be good for those.
