I just took apart the K241 in a '100' I bought in '18. I had it running then and remember as having a 'knock', especially at idle and part throttle. I was expecting to grind the crank .010 and put a new rod in. What I find is the crank is actually .012 under (1.488) and the new-looking rod is already a .010 under. (well I am guessing about the rod, I haven't checked it.) MY questions:

1. What are my options as far as making a fit between the rod and crank? Is a .020 rod available? What are your thoughts about just filing the cap until it 'Plastigauges' at .001? I don't expect it to do any real work again while it belongs to me.

2. Can anyone tell me the torque specs. for the rod? This is the rod with studs and nuts. I know the spec. is different for a rod with bolts and a rod with nuts. For my reference, Can you tell me specs. for rods with both bolts and Nuts?

Thanks!

There are aftermarket 0.020" undersize rods available. All torque specs are in the service manual that is a free download from Kohler's website.
