Description
Overview:
This Crankcase Clutch Side is a genuine Stihl engine housing for TS410 and TS420 disc cutters, supplied under MPN 4238 020 2909. It forms the clutch-side half of the crankcase, providing a rigid, accurately machined base that supports the crankshaft, clutch and associated seals and bearings.
