May be a dumb question but....cylinder liner specs state:
Cylinder Liner ID (RV): 2.992
Cylinder Liner ID (AL): 2.998
What the heck does (RV) and (AL) mean ??????

P.S. Piston Dia. is 2.989

I do believe they are minimum and maximum tolerances. ;)

In Kubota Vernacular - Reference Value & Allowable Limit
For example on my M4500 valve stem to guide clearance reference value = 0.0016 to 0.0028. Allowable limit = 0.0039. So... new or rebuild shoot for somewhere inside the reference value range, when simply reassembling old or re-using you can use it as long as it's under the allowable limit (you'd probably normally call it the "service" limit).

In other words 2.992 = new (or same as), up to 2.998 = useable (maybe/sort-of) 2.999 = worn out
