Product info
- Item number
- MSH-938821
- Position
Standard cylinder bore: 3.937" (100mm) bore. 1st. ring: 1.2mm. 2nd ring: 1.2mm Oil ring: 2.0mm Stock replacement for 107" models. Comes with a chrome top ring, a ductile iron Napier 2nd. ring and a chrome flex-vent 3-piece oil ring. Tech tip: Piston grooves vs piston rings. It's not difficult to determine if a Hastings piston ring set will fit a certain piston. You should measure the height of the piston groove in the piston itself. The 2 top grooves will be for compression rings, the lower groove will be for the oil ring. In most cases Hastings oil rings are of the low tension 3-piece flex vent type. Ring heights are listed for reference. Tech tip: Piston oversizes. For each oversize cylinder diameter will increase with .010" (0.254mm). The standard bore of the cylinder is listed for reference.
