Dale, If someone else answers a question before I see it,I usually don't answer a question. However all the answers have been opinions, with no facts. You know what they say about opinions,they are like arm pits, most everyone has more than one. Now to give you a opinion I hope you can use.
The torque specs. that you are asking about are not listed in the regular I&T manual, but rather in the I&T STANDARDS UNIT MANUAL. This is the one with the red-orange cover. This manual list all of the clutch, carburetor, and ignition distributor information. However on the torque specifications on the mounting bolts on the clutches, they use a chart for the "Nominal Torque for Tightening Stud Nuts and Bolts". The chart lists the following: This is for both stud or nut. 1/4 --- 55-85 in. lbs. 4.5-7 ft. lbs.
5/16 -- 110-165 in. lbs. 9-14 ft. lbs.
3/8 --- 190-285 in. lbs. 16-24 ft. lbs.
7/16 -- 295-445 in. lbs. 25-37 ft. lbs.
1/2 --- 450-680 in. lbs. 38-57 ft. lbs.
9/16 -- 640-970 in. lbs. 53-81 ft. lbs.
5/8 --- 880-1300 in. lbs. 73-110 ft. lbs. With a regular torque wrench you would use the ft. lbs. values. I hope this answers your question.
