FAQ

Q: How do I confirm this piston fits my Perkins 1006-6T engine?
A: Verify your engine’s serial number and existing piston specifications. This piston is designed for the 1004-4T and 1006-6T models with a 108mm bore and 53mm compression height. Always measure your current piston dimensions and compare with the specifications listed above. If your engine has been modified or rebored, consult your service manual for exact requirements.

Q: Is this a complete piston assembly? What components are included?
A: Yes, this product includes the piston body with the piston pin installed. It does not include piston rings, circlips, or connecting rods. We recommend purchasing matching piston rings (sold separately) for a complete engine overhaul. The pin is pre-installed for convenience, but verify pin diameter compatibility with your connecting rod.

Q: What maintenance should I perform when installing new pistons?
A: When replacing pistons in a Perkins 1004-4T or 1006-6T engine, we recommend: 1) Inspect cylinder bores for wear and measure for roundness; 2) Replace piston rings with new ones matched to this piston; 3) Clean and inspect connecting rods and bearings; 4) Use proper assembly lubricant during installation; 5) Follow manufacturer torque specifications for connecting rod bolts; 6) Perform a compression test after reassembly to verify proper installation.
