FAQ

Q1: How can I confirm this valve set fits my specific Kubota engine model?
A1: Cross-reference your engine’s model number (e.g., D1503, V2203) with the compatibility list above. The most reliable method is to match the OEM part numbers (16484-13110 / 16484-13120) from your original parts or service manual. Our technical team can also assist with verification.

Q2: Are these valves sold individually or as a matched set?
A2: This listing is for a complete set, including both the intake valve (1g852-13122) and the exhaust valve (1g852-13121) required for one cylinder. For multi-cylinder engines, please order the corresponding quantity of sets.

Q3: What maintenance is recommended after installing new valves?
A3: Proper installation is critical. We recommend having valves installed by a qualified mechanic who will ensure correct valve clearance adjustment, seat grinding, and stem seal replacement if necessary. Always follow the engine manufacturer’s specified break-in procedure to ensure proper seating and long service life.
