Baron MLG Door Hinge Kit

M1001


Category: Baron

Type: Kit



Main landing gear door hinge kits from Marsh Brothers Aviation for all models of Beech Baron and Travelair.

Avoid unnecessary and costly repairs by installing AeroTough™ GF polymer bushings. This preventative maintenance solution will ensure that you will never have the complications with seized bushings that traditional metal bushings can exhibit.

Lifetime lubricated AeroTough™ bushings prevent problems:

  • Eliminate anxiety about damages to the supporting structure
  • Never worry about lubricating tough-to-access places
  • Zero risk of corrosion between sleeve and bushing

Be proactive: The cost to repair greatly exceeds the price of prevention. Don’t wait for disasters to occur. Make the change now!

Note:

    Accessing the main landing gear door hinge brackets is difficult. The install kit is not essential but it is highly recommended because it make the installation of the main landing gear door hinge kits much easier. The install kit includes a 0.251” reamer to re-size the ID of the bushings in case they are tight, a press-out and press-in jack that can be used to push out the OEM bushings and press in the new polymer bushings, a push pin which is an adapter for the screw jack, some “Stick-it” for holding washers etc. in place during installation and a temporary distance piece to keep the housing flanges from bending.
  • An essential part of your landing gear maintenance checklist is the need for periodic lubrication of hard-to-get-at door hinge bushings. Achieving proper lubrication is challenging because access is difficult. If these bushings are not lubricated regularly, corrosion will result. This can cause the bushing and sleeve to fuse together over time, resulting in problems with the door rigging and the operation of the aircraft. This could lead to an inoperable gear door or the cracking of the gear door - a safety issue for sure and at best, an expensive repair. Our kit is insurance against the possibility of future problems.
  • The solution to this problem is AeroTough™ GF polymer bushings. These non-metallic bushings can be easily installed and will provide smooth grease-free operation. AeroTough™ bushings will never require lubrication. The polymer material is designed to incorporate its own lubrication. If someone doesn’t know our bushings have been fitted and decides to squirt some lubrication into the hinges, it’s no problem. Our bushings are quite happy to run in oil or grease – it’s just not necessary!
