Artikel-Beschreibung

Hastings, 2-3/4" bore piston ring set. +.050"

Used with late style 1950-1973 type pistons with 1/16" gray iron parkerized compression rings and the 3-piece flex-vent style chrome oil rings. Also fits 52-56 K, KH, KHK 55" (900cc) Flathead models. Std Bore: 2.745" (69.723mm). 1st ring: 1.6mm. 2nd ring: 1.6mm. oil ring: 4.75mm. Note: OEM 1929-1949 pistons are equipped with 3/32" (2.3mm) 1st. & 2nd rings and 1/8" (3.2mm) oil ring, for these Hastings rings see 1950-1973 Flathead model years. These rings will not fit the 1929-1949 early type pistons. 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.
