Can anyone help.....
I am getting conflicting information from my machine shop and parts vendors. Sealed Power Pistons is saying one thing my machine shop says another........

with piston depressions at 6:00 (or bottom half of piston)......
is this the correct orientation for these rings??


top compression ring at 12:00
second compression ring at 6:00
2 piece oil ring gap at 10:00- 11:00
oil ring expander gap (spring inside oil ring) at 4:00 to 5:00thanks for the help

Got a 90 Unit Repair Manual and your description is what is in the manual .

I have not rebuilt a 6.5 but i have rebuilt alot of gas motors. you really just don't want the gaps aligning. what are the 2 varying opinions, i would bet that either is acceptable. i would go with the piston manufacturer or sellers specs as they designed them and would know best, machine shops unless they specialize or see alot of deisel motors are looking at fairly broad specs and not piston specific.

Go with the manual if you have one.
I usually put the gaps alternately just ahead or past the piston pin hole 180 degree apart , i do the same with the 3 piece rail oilring , stagger the 3 pieces. So that no gap will line up with any other ring gap above or below .
