Ring gap? 2001 xc300
Hi there,
I'm ready to assemble my 2001 xc300 top end. I have my cylinder just back from being replated by Langcourt's. They did a nice job. I have an Athena A size piston kit. I sent the piston, but not the rings, with the cylinder to Langcourt. If I drop a ring into the bore to check ring gap, I am seeing about .014 or.015 inch ring gap (.36 or .38 mm). That looks pretty tight to my untrained eye, and I don't have a gap spec to check against. I just wonder if I'll run out of gap when the engine gets hot. Thanks in advance for a clue or two. -Dean 2001 xc300 |
manual says
300 cc: STD: 0.5 mm - Limit: 0.8 mm it may be different with athena pistons - i know wiseco uses a different spec. this .5mm/.8mm gap spec seems awful big to me. |
This from Athena:
"Hello, The difference 0.01 to 0.03mm (0.35 →.38 )in the ring end gap of the rings doesn?t affect the performance of the engine. The clearance piston-cylinder wall that we use is from 0.04 to 0.06mm Thank you" |
rule of thumb on most engines is .004'' gap per inch of bore.
