Gap for wiper rings in oil contol pack

FarmerHR · Jan 8, 2013

What is a typical gap for the wiper rings on the oil conrol ring ring pack ?
I have seen data for the compressioin rings gap of 0.010 to 0.017. I have not seen similiar data for the wiper rings.
Thank you for your help.

the standard gap is .003-.004 for every inch of cyl. bore. on compression rings.
the compression ring is the top ring, the wiper ring is the second ring. both rings use the same gap.
the oil ring is totally different looking and can be in three sections. centre is the expander with 2 rails, one above and one below. and the rails shold be positioned 90 degrees from each other. also end gap on rails is not as critical and should be at least .010.
