FS-40 Engine Pushrod Shield - O.S. Engine OS45266111  [OS45266111]

FS-40 Pushrod Shield Details

The pushrod shield, catalog number O.S. Engine OS45266111, is supplied as a replacement component for the FS-40 engine family. It helps retain and protect the pushrod area on FS-40 assemblies, ensuring alignment is preserved during workshop adjustments on RC nitro models.

Fitment is direct: remove the head or specified access cover to reach the pushrod area, place the shield over the assembly, and secure via the engine's original mounting locations and fasteners. Use hand torque per the original recommendations and check for unobstructed pushrod travel before final reassembly.

As a maintenance aid, the shield reduces the risk of debris contact and unintended displacement while you tune or service the engine. It is a protection and service component only and does not change timing or internal tuning parameters.
