 47mm, aka 1.85" inch bore piston and ring assembly. Includes: piston with ring.  Part number 94130  New AFTERMARKET part.  The chainsawr has had this piston custom engineered to exceed OEM quality, and replace the 2 thin rings with one standard piston ring for increased compression, and better wear duration.  These pistons are an excellent replacment for older saws with low compression.   Fits Mcculloch Pro Mac 610, 650, PM610, PM650, Eager Beaver 3.7, Timber Bear 3.7, Timberbear 3.7, FR 3.7 and others  We strongly recommend also replacing the bearings that press into this piston for the wrist pin and small end.  Available here: piston bearings
