Engine Adaptor Mounting Screw OS29026400 by O.S. Engine  [OS29026400]

Purpose and expected service

This adaptor mounting screw serves as a compact RC-scale fastener to secure an engine adaptor to its mounting flange or plate. The text that follows highlights practical maintenance, service life considerations, and correct usage without asserting any undocumented technical specs.

Fit and purpose: fitted where an adaptor meets an engine housing or bracket, the screw keeps the adaptor aligned and seated during normal model operation. It supports consistent alignment between the adaptor and adjacent drivetrain components.

Installation notes: pick the appropriate driver for the screw head, begin threading by hand to avoid damage, and tighten progressively. For multi-bolt flanges, use a cross-pattern tightening sequence. Avoid overtightening and only use thread locker if the parts list or assembly guide recommends it.

Maintenance and tuning role: include this fastener in regular checks to confirm it remains secure and mating surfaces are clean. After making tuning adjustments that change drivetrain geometry, re-verify the screw torque and adaptor position following test runs.
