FAQ

Q1: Is this piston compatible with my Xinchai 490 tractor engine?
A: Yes, this 90mm standard-size piston is designed for the Xinchai 490BT, C490BPG, and A490 engine series. We recommend verifying your engine’s model number and bore size (90mm) to ensure exact fitment before installation.

Q2: Does the kit come with piston rings or just the piston assembly?
A: The kit includes 1 piston, 1 piston pin, and 2 snap rings. Piston rings are not included in this assembly. Please order rings separately if required for your rebuild.

Q3: What is the difference between standard and oversized pistons?
A: This is a standard size piston with a 90mm bore diameter. Oversized pistons (e.g., 0.50mm or 1.00mm over) are used when the cylinder bore has been machined to a larger diameter. For standard rebuilds without cylinder boring, this part is the correct choice.
