Got my block back from the machine shop and want to put my Kohler back together.  The rings that came with my aftermarket kit are different than the ones on the example sheet provided.  All of the top rings show a chamfer but mine is square.  Top and middle rings are different thicknesses so I know which goes where.  For those of you who has installed kits, are these normally square?  I have an email in to the supplier but I want to get going on the assembly.

The top compression ring can be ether square or beveled.if punch marked or etched goes up . Otherwise doesn't matter orientation.

Square rings are common replacements for beveled.  Most aftermarket parts companies do that.  Cut costs where you can is the motto, I guess.  Sometimes I think square rings give better compression, too, but I can't prove that for certain.

Beveled, etched, or"pip" mark goes up. If square, it makes no diff.

so now you know how to install the rings

after you have the rings on the piston now to align the ring gap

set the top ring then the middle ring should be set at 120 degrees then the oil rings at 120 degrees to the middle ring

 

but I set my rings different

set the top ring then the middle ring goes at 180 then if it is one piece oil ring I set it 180 degrees to the middle ring

if the oil ring is a 3 piece then I set the top oil ring 90 degrees to the middle ring and the bottom oil ring is set 180 degrees to the top oil ring

I set my rings as you do lyall.  Always have & always will.  Just makes sense having the longest path possible between gaps.  Main thing is not to have any gap inline with the crank, or 90 degrees from that.

I've always done the same.  I spoke to a Briggs educator that said it didn't really matter because they rotate while running.  It's still piece of mind for me to stagger them.
