piston ring replacement procudeure

i was wondering what the procedure on replaceing the piston rings on a ka24de. any tricks or recomendations on someone who has never done it before. i have done the head gasket along with replaceing the oil pan gasket so i know how to get dirty.
thanks
Justin

I haven't done it on the ka but I have done it on my LS/Vtec. Take off the oil pan, and anything that prevents you from getting to the rod bolts, unbolt the rods, take off the cylinder head (sounds like you have done this before), push the rods and pistons up through the cylinder, Put the new rings on, hone the cylinders, and put the shit back on. It's not a small job, but it's pretty easy. While you're doing that you should replace the pistons, low or high compression, for whatever you plan on doing. Make sure to look up the pounds each bolt is supposed to be torqued down at. This is very important.

thanks but that is a little too basic i need more detales if you can provide it

come on people i have the FSM for ka24de and sr20 but i just need some need to know tips and tools i need. i know you need to heat up the pistons and other things. get me good detales pls

thanks but that is a little too basic i need more detales if you can provide it

like s13wanabe said, take off the oil pan, remove some stuff that might be in the way of getting to the rods, then remove the head.

then put a wrench on the crank pulley and turn the crank so piston one is all the way down or in the best position for you to get to the rod bolts.. so then you unbolts the C clamp on the rod and then put the cylinder out to the top.

make sure you mark it wich way the C clams and the piston was facing, because at the position that its in right now is the perfect position because it already broke itself into it, and if you mix up the C clams or put the rods on backwards then it will start wearing out again and try to break in again.

then turn the crank over again to take off the rod bolts on the next pistons, and then 3rd and 4th... or you can do it 4th-1st because to me the last one is the hardest to get to sometimes so i preffer doing the hard one first.

So now that you have pulled out the pistons, you should get a a tool to replace the rings, you dont have to worry about breaking the old ones , and they do break pretty easy, and if there is no way you can get a tool for the rings then i guess you might have to do it the old way, and thats to try and put the new rings on by hand... practice with the old rings, take one off then put it on again, try to take off rings off the old cylinder and then put all 5 rings back on that one cylinder without breaking any, you will get a feel what its like with the old ones before you try to mess with the new ones and start breaking them :nono:

It is suggested that when you replace the rings its better to replace the C clamp bearings as well and the rod bolts with new ones...its up to you, but its a suggestion.

OK, so now lets say you have all the pistons ready with new rings and ready to go... get a ring compressor, before you compress the rings.. make sure that every rings gap is facing away from each other... you know what im talking about? since the ring is not solid it has that cut and when you put the rings on each cut should be opposite from the ring bellow and above it, this will prevent the oil from going all the way to the top of the piston, just think about it, if you put all 5 gaps on one side then the oil wont have a problem making it all the way to the top. the rings move around, but you get the picture i hope.

compress the rings, and this will require 2 people one at the bottom making sure that the rod isnt hitting the crank and one on top hammering the piston in... when i say hammering, not the matal part of the hammer but the wooden part, i even use a clotch to put on top of the piston before i hammer it with wood or anything. One more thing, dont forget to oil up the cylinder walls, that will help the piston slide better, you dont want to do it on dry, you will scratch and push and will just make it harder.

so turn the crank to where its the easiest to put the rods back on, and do the same for 2-4 pistons, tighten the bolts to the right torque, head gaskets, this and that, and you know the rest...

good luck...

you do not have to hone the cylinders really because the pistons rins have already polished the cylinder walls so they are nice and ready to go, unless you have wear on the cylinder walls and that will reguire for a bore, wich i doubt it needs.

thanks a lot that was good
