2hp knock

[free1986]

It may be a trick of the photo, but it looks like there is a crack in the connecting rod from the right side cap bolt hole toward the bearing? Not sure that it would cause a knock, but it doesn’t look encouraging.

This chart shows 5 – 5.5 Ft Lbs but I’d go with inch pounds for better accuracy, 60 – 65. Since a 1/4″ drive socket seldom fits on the bolts without grinding it down, I use a screwdriver with a square shank and snug them up with a wrench on the shank before folding the locks over. Since I can’t get a torque reading this way I just guesstimate it.

Often wondered why OMC used those little hex head screws that you couldn’t get a socket on…Trying to apply proper torque with a screwdriver bit is tough, be sure to replace those lock tabs also…
