Piston and cylinder ID and question

[dmcummins]

I'm going through some of my old stuff and I'm wondering about these pistons and cylinders. I think they are 2.4S, but I'm not 100%. And I only have 5 of them.




Is it worth having these checked out and how hard would it be to find a 6th to match.

Your picture of the piston underside shows "84p11" which is a 2.4S piston.

The piston shows "84p11+" actually. Are these worth having checked to see if they are in spec and how difficult to find a 6th?

I think it will be a challenge to find another "+" oversize one to match the other 5. The cylinder height also has to match the others. This is assuming the 5 are in good shape and in spec.

So the + means its oversized. Oh well, Ive had these for several years and I am starting to sort through some of my stuff and trying to figure out what's worth keeping.

Are the cylinders heights marked or do you just measure them?

The Cylinders are marked. From your picture you have height group 5. The triangle on the bottom sleeve area with the 5 in it.
