OS28602200 Crank Pin Stop Screw for GT60 Engines - O.S. Engine  [OS28602200]

Overview: crank pin stop screw

This O.S. Engine OS28602200 crank pin stop screw is supplied as an accessory for GT60 engines used in RC models. It acts to restrict axial movement of the crank pin so the crank assembly remains correctly located during maintenance and rebuilds.

The item is a threaded stop screw that engages with the crankcase or crank assembly to prevent the crank pin from backing out or shifting while other engine tasks are underway. Fitting is a quick step in the engine disassembly and reassembly process and should follow the engine manufacturer's recommended service procedure.

For workshop and tuning tasks, the stop screw is a handy aid: it holds the crank pin steady during inspection, bearing swaps, and when positioning the crankshaft prior to final assembly. Handle it as a precision part and check that it is correctly seated each time the engine top-end or bottom-end is opened.
