As I asked about above, You have to overtorque at first to stretch the bolts. It is in a note in the original Kohler Manual. Not overtorquing leads to the bolts stretching and the rods failing. This is a common problem for first time rebuilders. The note is something that was pointed out in Kohler training but is not obvious in the manual..
I also use plastigage to get a real reading of the clearance. Good Luck, Rick
yes it does say that in the kohler manual i assumed that was for kohler con rods only.
when i got a new rod it was a saint bird brand that was sent and the torque specs that came with told me tighten it to 260 in/lbs with no mention of over torquing it.
the kohler manual after closer reading says that con rods with bolts need to be torqued to 285 in/lb after over torquing it 20%.
it also says that rods with nuts are to be torqued to 260 in/lb with no over torquing.
so i went with the specs sent with the rod thinking that they were right as it was not a kohler rod.
has any one worked with saint bird rods and what did they torque them to so that they worked right??.
this is where i got my rebuild parts if you look down the page you will see the specs he sends out with the rod.
by the way he also sent a insta-fire plug with a part number of ( mgd-89013 ) if i looked it up correctly it is for a briggs&stratton not a kohler engine..
