Kubota V1902 Piston Ring STD 19274-2105

This is a per-cylinder ring set. The Kubota V1902 is a 4-cylinder engine — order 4 of this part for a complete rebuild. The D1402 is 3-cylinder — order 3. If only one cylinder measured low on compression and the bore is still at STD, you can replace rings in just that cylinder, but most rebuilders do all cylinders at once.

Measure the cylinder bore with a bore gauge. If the bore is at or very close to the standard 85mm spec and within Kubota's wear limit (typically 0.15mm over), you can use STD rings. If the bore is worn beyond the limit, the cylinder will need to be bored oversize and you'll need oversize rings. If you haven't measured and the engine was running with high oil consumption, STD rings are the correct starting assumption before inspection.

Yes. The V1902T turbo variant uses the same piston and bore specification as the naturally aspirated V1902. The turbocharger is on the intake/exhaust side and does not change the piston or ring dimensions. OEM# 19274-2105 is correct for all V1902 variants including T, E, and B.
