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

What this stop screw does for your GT60

This O.S. Engine OS28602200 crank pin stop screw is an accessory designed for use with GT60 engines in RC applications. It limits the axial motion of the crank pin to ensure the crank assembly stays correctly positioned while you carry out maintenance and rebuilds.

The component is a threaded stop screw that mates with the crankcase or crank assembly to prevent the crank pin from moving out of place during other engine servicing tasks. Fitting it is a brief, straightforward step during disassembly and reassembly and should be done in line with the engine maker's service sequence.

In practical shop use, the screw is useful for stabilizing the crank pin during visual inspection, bearing replacement, and when setting crankshaft location before final assembly. Handle it as a precision item and confirm it is seated correctly each time the engine top-end or bottom-end is opened.
