ENGINE BUILDING PRECISION THAT MATTERS

Why Proper Piston Ring Gap Matters

Proper piston ring end gap is an important part of engine assembly. The Granatelli 540100 Electric Piston Ring Filer helps make the filing process more controlled and repeatable, allowing builders to gradually remove material while checking the ring gap throughout the process.

Accurate Ring Gaps in Three Steps

01
Check the Initial Gap
Measure the piston ring in the cylinder and determine the required end-gap specification.
02
File Gradually
Use the electric filer to remove material gradually and maintain controlled ring-end preparation.
03
Measure & Verify
Frequently check the finished ring gap until the manufacturer's recommended specification is achieved.
