Connecting Rod Screws: How Tight?

[massimofinance]

1982 Evinrude 115HP 2-stroke, VR-4, VRO<br /><br />The book says 30-32 ft-lb, I started at 20, and the torque wrench is clicking, but there is no way I feel comfortable going higher. Any advice? <br /> <br />The book (Clymer's) says 1985-on 120-140 HP is 42-44, and 1986-on 200-225 HP 42-44, then all others 30-32. (mine is under the all other's category, I figure)<br /><br />Thanks.

You definately want to torque them to specs or you will wind up with one of them sticking out the side of the block. 30-32 ft lbs sounds about right.

now ya see why I say always use new rodbolts. its a lot of stress on a small bolt. I have seen many used ones break. some used ones break when ya retorque them. those are the lucky ones.

Not a good idea to use used rod bolts, get new ones. Do the torqueing at 5lb increments,go through once at 20,then 25 and then your 30-32 ft. lbs. The old rod bolts have already been stretched to the limit. Better a few cents for a new bolt than dealing out a lotta bucks for a new block

I have always used a torgue wrench reading in in./lbs. when doing rod bolt's, or anything else on these aluminum engines. I have never been comfortable with a breaker, or pointer type wrench reading in ft./lbs., They just are not sensitive enough. The best wrench I have found is the Snap-On dial type torqueometer. Now days! that wrench is probably about the same cost as a rod & piston. For me, it was a cheap investment.
