FAQ

Q1: Is this piston a direct replacement for the Kubota 1J808-21110, and does it include piston rings?
A1: Yes, this piston is a direct OEM replacement for part number 1J808-21110. It is machined to the exact specifications of the original. However, please note that this listing is for the piston only. Piston rings (e.g., part number 1J808-21130) and the piston pin are sold separately to allow you to choose the correct ring set for your specific engine variant.

Q2: Can I use this piston in a Kubota V2403 engine that is not a CR-T (Common Rail Turbo) model?
A2: This piston is specifically designed for the V2403-CR-T (Common Rail Turbo) and D1803 engines. While it may physically fit other V2403 variants (like the M-T or DI-T), we strongly recommend verifying the compression height and bowl geometry. Using the wrong piston type in a non-CR-T engine can alter the compression ratio and lead to poor performance or engine damage. Please check your engine serial number and consult your manual.

Q3: What maintenance checks should I perform before installing this new piston?
A3: Before installation, we recommend the following steps: 1. Measure the Cylinder Bore: Ensure it is within service limits and free of scoring or excessive wear. A hone or rebore may be required. 2. Check Piston-to-Bore Clearance: Use a feeler gauge to confirm the correct clearance (typically 0.04-0.08 mm for this type of piston). 3. Inspect the Connecting Rod: Check for bending or twisting and replace the rod bearing as a precaution. 4. Lubricate: Apply clean engine oil to the piston skirt, pin, and rings before installation to prevent dry start.
