Aerostar Wiebel NLG Oleo Kit

The Marsh Brothers Aviation Wiebel NLG Oleo Kit replaces the OEM metal lower bearing and floating piston with a polymer bearing and piston. The traditional use of rubber O-rings in dynamic sealing applications are replaced with the polymeric lip seals and the metal piston scraper is replaced by a polymeric wiper.

This upgrade provides three key benefits improving the reliability of the NLG shock strut:

1. The possibility of metal-to-metal contact causing damage to the piston sealing surfaces is eliminated.

2. Typical O-ring failure modes are eliminated.

3. Cold weather sealing performance is improved due to the combination of the lip seal design and the low temperature characteristics of the proprietary elastomeric polymer which makes for a superior dynamic sealing system.
