WHEN TO REPLACE

Signs Your Kubota V1902 Piston Needs Replacing

Replace your V1902 piston and rings if you notice:

⚠️ Blue or grey smoke — oil burning through worn rings
⚠️ Excessive oil consumption between service intervals
⚠️ Piston scored, cracked, or damaged on teardown
⚠️ Low compression confirmed by cylinder test
⚠️ Engine overhaul or full rebuild in progress
⚠️ Bore measured at STD spec — piston replacement warranted

FAQ

Common Questions

What is the difference between SKU 2428 (ring set only) and this kit (2432-2428)?

SKU 2428 (19274-2105) is the ring set only — 3 rings for one cylinder at $18.97. This kit (2432-2428 / 19274-21110) is the complete piston assembly: 1 piston + 1 ring set + 1 wrist pin + 2 retaining clips at $49.99. If your piston is still in good condition with no scoring or damage, you can save money with just the ring set. If the piston itself is scored, cracked, or worn beyond spec, order this complete kit.

Does this piston assembly fit both the V1902 and the D1402?

Yes. Both the V1902-DI (4-cylinder) and D1402 (3-cylinder) share the same 85mm bore piston specification. Order 4 kits for a full V1902 rebuild or 3 kits for D1402. Confirm your bore is at STD (85.00–85.15mm) before ordering — if the bore has been machined oversize, you'll need oversize pistons instead.

Are the wrist pin and clips already matched to the piston, or are they generic?

The pin and clips included in this kit are matched to the OEM V1902 piston specification. They are not generic — they are the correct diameter and length for the V1902/D1402 piston and connecting rod combination. No additional sizing or fitting is required beyond standard assembly procedure.
