What do you guys use to torque the cam to spec?
I use a Torque Wrench
i currently have a torque wrench that the lowest setting is 10 lb
but the 6mm bolts only need 9lb
so i was wondering what torque wrench to get
i think 9 ft/lbs = 108 inch pounds
i guess what i mean is what kinda torque wrench do you guys use for cam specs
well you did ask WHAT people were using...
I would torque it down to 10 lbs... then take a ratchet and back it off a bit, 1 lbs over torque is not gonna hurt the cam cap at all, I can vouche for that.
my friend said the last time he did it he used a 10 ft lb wrench and the cam was so tight the starter couldn't even turn the motor over...
he's bullshitting you because the very first time I put cams in, I hit them with an impact gun lol the guy drove around for about 3 months and came back for me to install some type r cams that he bought, luckily that time around I knew EXACTLY what I was doing.
try going to 10lbs, then go back a 1/4 turn
I have a pretty old torque wrench, it's a craftsman, that doesn't click, nor ratchet <-sp? but it has two bars that connect over the socket, one is a handle, the smaller a needle that measures on a small meter, it only goes up to like 85 lbs, but also does 1 lb/ft, but also 1 Nm.
i got a small craftsman that goes to 20 ft lbs and i got a larger new mastercraft that torques to 250. actually a pretty decent torque wrench for not having to buy a 500$ snap on one.
and for inch lbs to FT lbs, depending on what you are doing, divide or multiply by 12.
eg. 144inch lbs. 144 / 12 = 12ft lbs.
10 ft lbs x 12 = 120 inch lbs!
yup, i think i'll be going to sears to get a small one that only goes to 20 lbs
inch pound clicker torque wrench at sears was only 65 bucks
25 to 250 inch pounds
