My assembly manual is missing the page that indicates bolt torques for assembling the half shaft to the differential yoke and to the spindle flange. HELP!!! Anyone have the torque specs for inner and outer ends, or all we all missing that page??

Re: 66 BB half shaft bolt torque
Inner u-joint cap bolts= 40-50 lb/ft ( I use 45 lb/ft)
Outer u-joint flange bolts= 60-90 lb/ft ( I use 75 lb/ft)In Appreciation of John Hinckley- Top

Re: 66 BB half shaft bolt torque
Half-shaft u-bolt nuts are 14-18 lb/ft. However, I believe Ed has a big block, so he should have the caps with hex bolts. Of course, there might be some big blocks out there with u-bolts. You know what kind of big blocks those are.In Appreciation of John Hinckley- Top

Re: 66 BB half shaft bolt torque
Gentlemen: Yes, it's a big block with a posi rear, and it has caps on the differential yokes. A friend's assembly manual had the page I'm missing but it only illustrates a "U" bolt set-up with torques at 14-18. So, I then went to the options section hoping to find a posi rear page. Found one page but it does not show half shafts. Am I missing another page?- Top

I think you'll find it in the L-36 or L72 section. In those days, the cap-type axles were part of the big block option.In Appreciation of John Hinckley- Top

Re: 66 BB half shaft bolt torque
The '66 L-72 index sheet shows the half-shaft on sheet D3 and the hood grilles on sheet D4; my '66 Assembly Manual is missing those two sheets too. However, the '65 L-78 sheets and the '67 L-36 sheets both show the half-shaft cap bolts as 40-50 ft-lbs.- Top

Re: 66 BB half shaft bolt torque
Much thanks Joe, John and Gary. Hopefully I'm not about to wear you guys out but it's now onto the spring and its' Retainer Cups. Prior to reading the last issue of Corvette Restorer I had no idea that the cup sleeve was to be swaged over. I plan on it attempting it with a 1-1/4" dia ballpean hammer - placing the 1-1/4 ball on the cup and tapping on it with with another hammer. I know I should not hammer on another hammer but........... I'm reasonable proficient with a hammer and whatever else comes to mind as a potential tool. Anyone have an issue with this, or a better idea? I'd rather not rent the tool mentioned in the article. Wife is away and I have this weekend to myself to make significant progress in finishing the rear. After this it's simply assembling the spring, brakes, lines, bleed and start-er-up!!!- Top

Re: 66 BB half shaft bolt torque
Looks fine. How did you do it? Incidentally, I just checked my 64. I did this car about 5 years ago. The T/A cups are original and look like yours. You did a nice job. On my 64 spring cups however, I never swaged them. The car has since seen about 3,000 miles and the non-swaged spring cups never came out of the spring. It's not right but perhaps not critical? Also interesting to note: I did not have any problems at all when doing the 64 rebuild. Except, apparently, that the spring cups are not swaged. Don't understand why this 66 has been difficult.- Top

Re: 66 BB half shaft bolt torque
Wow - never ending issues. Spring vinyl liners? I had seperated the leaves of my curled end repro spring, painted the leaves and have new uncut vinyl liners. This repro spring had liners that were about 1/2" shorter per side than the spring leave. I would think that the liners should be longer than the leave, so that the leave slides on vinyl and does not rub on the metal leave below it. Anyone agree/disagree!- Top

The originals were, indeed, longer. ROUGHLY an inch, or so.In Appreciation of John Hinckley- Top
