I am almost certain they are sleeved.
Not only can I see the sleeve but there are also casting grooves around the diameter which I assume are there to help grab the sleeve and pull it up.
Question is what the heck goes back in.
Cummins made statement Kukje is going to manufacture and stopped using sleeves.
I have sleeves, ....... maybe I have a model before they stopped using sleeves??
My ESN is CM1L00247
Not something I have been able to cross reference yet
The pdf file ptsg supplied has a different numbering sequence, so again I am really confused as to what I actually have??
You guys are way smarter than I am maybe we can figure this out together.
The link ptsg supplied has a overhaul kit for Cummins A2000
Sleeves
Pistons
Rings
The works for 300 plus shipping
Did not think this was going to be such a mystery trying to find parts.
Regretting taking this project, Trina to save money ugh!!!!!
