torque angle

I do not have a perfect answer but , I would not tq less that 75# with the proper lube.

I do not know if they need to be 85....not less than 75 is what i know.
The mains at 90# is what is gonna screw you

Maybe is was 90 lbs plus 42°

65# is too little...in this application.

Whatever method you decide on, tighten 1 up w/o a bearing in it and check to see if the I.D. of the rod is round and to size at that tightness. Use the bolt stretch gage if you want to see where you're at for sure, if you can afford to replace those wsb bolts you can afford a gage. lol Good luck

I've been running Oliver rods for years. I always use torque/angle to get close, but use a micrometer with a vernier scale that can be read to .ooo1" resolution to measure the resulting bolt stretch. At the end of the day, stretch is what you are striving for because it is directly related to how much force (preload) is on the bolt.

You'd be surprised at how inconsistent the amount of torque that's required to achieve the correct results. That, of course, is why you don't use torque to set the bolt preload if you need precise results.

I create a simple chart to record the free length of each bolt, its position in the engine, the target stretch value, and the angle that was necessary to achieve the target. Each year, when I teardown, inspect, and clean my engine, I keep the bolts in the same order and compare the measurements to the previous year's assembly.

If you want to do the job right, follow Oliver's instructions to the letter AND measure the resulting stretch. You'll sleep better.
