Details of the silencer assemble screw

The O.S. Engine OS44925300 silencer assemble screw is an M4X110 threaded fastener designed for silencers identified as F-5040 and FSa-110. It links the cylinder head outlet to the muffler body, ensuring the exhaust assembly remains properly aligned while the model is running.

For installation, align the parts and begin threading by hand to prevent cross-threading. Tighten until the silencer is seated firmly; avoid over-torquing which can damage inserts or studs. After initial runs, re-check the joint for any signs of looseness or exhaust leakage.

Correct mounting keeps exhaust positioning consistent, which can influence backpressure and therefore engine consistency on nitro setups. A straight, secure fit reduces stress on the silencer, manifold, and mounting studs.

Will this screw affect engine running?

Indirectly. By keeping the silencer correctly positioned, the fastener helps maintain the intended exhaust flow and backpressure, which supports stable engine behavior on nitro models.

Can I replace it with a different length?

Only if the replacement matches the required thread diameter and insert engagement. Changing length may affect seating and could permit leaks or undue stress on mounting points.

Best practice for installation?

Hand-start threads, align components before tightening, apply moderate torque, and inspect after a short run. Use a medium threadlocker if vibration leads to repeated loosening.
