Manufacturer reference: W3839XH
Designation: PISTON RING SET 97.5MM
Brand: WISECO
This piston ring set is designed for engine refurbishment operations on roadsters equipped with a 97.5 mm piston. This kit allows for the replacement of all rings around the piston to restore the original clearances and geometry during a restoration or major maintenance operation. Ideal for work on vintage engines where bore precision and proper ring clearance are essential.
Before installation, check the bore, the condition of the piston, and the axial clearance recommended by the workshop manual. For a clean installation: clean the piston groove, inspect the cylinders with an endoscope, lightly lubricate the rings during installation, and follow the order and orientation indicated by the manufacturer. Always replace all rings to ensure even wear.
Rider tip: keep the reference W3839XH and note the diameter 97.5 mm during any order or refurbishment operation to avoid any compatibility errors.
