Technical question ! I am rebuilding the rear diff Posidrive on my 1980 corvette, i have replaced the clutch plates with a new kit. My question is how tight should this be to turn in the vice. Is there a set torque value that i could expect to have before it begins to turn.

Welcome to the site!
Here is a pretty good article with some pictures and info: http://www.superchevy.com/how-to/engi ... -and-c3-corvette-rearend/ From the article it states: "10. Eddie checks the clutch clearances with a torque wrench a second time to ascertain proper clearance. The carrier should turn with some resistance, but not extreme effort. The resistance shouldn’t be any greater than 45-50 ft-lb as a rule." Is that your question or something else? Matthew |

Some more info I found online...not specifically mine.
The 80-82 is a Dana 44 (I've seen it called a Super Dana 44) and it's specific to those years. These should be the torque values: These values are directly out of the GM Shop Manual for the 1980 Corvette: Pinion nut- 200-220 lbs. ft. Ring gear bolts- 45-60 lbs. ft. Bearing caps- 60-70 lbs. ft. Carrier front support- 65 lbs. ft. Carrier cover to frame- (sidemember bracket) 95 lbs. ft. Rear spring plate to carrier- 45 lbs. ft. Strut bracket to carrier- 30 lbs. ft. Camber Cam- 130 lbs. ft. Strut rod to spindle Support Attachment- 75 lbs. ft. Drive spindle nut- 100 lbs. ft. "Lubrication: To refill add 4 oz. of GM 1052358 additive or equivalent, then fill to level of filler plug hole with GM 1052271 or 1052272 or equivalent." |

I did this tutorial on inspection and rebuilding of the D44 Trac-Lock's a few years ago.
