Do you have to hone cylinders when replacing Pistons?
To make a long answer short, you should probably hone your cylinder when replacing piston rings.
Simply deglaze the cylinder with hot water and SOS pads to thoroughly clean it, and then look inside.
If you can still see the original hone marks (cross-hatching) then you likely will not need to hone the cylinder..
Can you put new rings on old Pistons?
Remember that the rings press against the cylinder bores causing as much wear to the bores as to the rings and that the pistons also wear out, especially the ring lands (the grooves where the rings sit) so to change only the rings is not a very good idea. New rings on old pistons in a worn cylinder, bad bad idea.
When should I replace my Pistons?
According to many industry experts, if the pin bore is worn more than 0.002″, the piston should be replaced. Measure the piston at its gauge point with a micrometer to determine if it has worn significantly. In cases of extreme detonation or heat, the skirts could have collapsed which will show on the gauge.
Can I reuse piston rings after honing?
Block has been cleaned and honed. If the piston is clean and the ring fits snugly in its groove but has no binding it is “likely” that it is OK to re-use it.
Do I need oversize rings after honing?
It’s standard practice to install new rings after a hone. It’s likely the rings you have are simply cast iron, and won’t have any problem being used again. One easy way to tell is to measure the end gap, by placing the rings down into the cylinder about 1/4 the way down.
Does honing a cylinder make it bigger?
Secondly, does honing a cylinder make it bigger? The crosshatch pattern will hold oil and help lubricate the piston and rings as the rings wear in to the cylinder. That is mild. A cylinder hone can also be used to bore a cylinder to a bigger size and that is wild.
