Aerostar Nose & Main Landing Gear Torque Link Kits

Marsh Brother’s designs and manufactures high performance self-lubricating bushings, bearings, and seals for the aviation industry.

 

 

Main Landing Gear Oleo Kit

(P/N M1004)

Available for all models of Aerostar aircraft. One kit will cover one main landing gear.

 

This preventative maintenance solution will ensure that you will never have the complications with traditional metal components and rubber seals can exhibit! Be proactive: the cost to repair greatly exceeds the price of prevention. Don’t wait for disasters to occur. Make the change now!

 

An essential part of optimal landing gear shock strut performance is seal integrity. This kit assures optimal landing gear performance when you need it. Proprietary lip-seal design coupled with high quality materials and advanced engineering provides a more robust dynamic seal, eliminating the possibility of extrusion or roll failures. Use of non-metallic lower bearings, upper cap and floating pistons eliminate the possibility of score marks on dynamic sealing surfaces leading to leakage. This kit is insurance against the possibility of future problems.

Wiebel NLG Oleo Kit

(P/N M1010)

 

This 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 is replaced with 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

Nose Landing Gear Torque Link Kits

(P/Ns M1011 and M1012)

 

Available for all models of Aerostar aircraft. 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 these common issues:

 

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

 

An essential part of your landing gear maintenance checklist is the periodic lubrication of hard-to-get-at bushings. Achieving proper lubrication is essential to maintaining safe operation of the aircraft. Inadequate lubrication can lead to corrosion.

 

  • Eliminate the risk of corrosion
  • Eliminate the need for repetitive lubrication

Main Landing Gear Airframe Trunnion Kit

(P/N M1007)

 

Available for all models of Aerostar aircraft. 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 place
  • Zero risk of corrosion between pin and bushing

 

 

An essential part of your landing gear performing optimally is periodic lubrication at dynamic joints. Achieving proper lubrication is challenging because access is difficult. Improper lubrication causes corrosion, which leads to premature wear and results in costly repairs (at best), or worse by risking safety. This kit is insurance against the possibility of future problems caused by insufficient lubrication.

 

  • AeroTough® GF polymer bushings are robust and inherently wear resistant
  • AeroTough® GF polymer bushings have built-in lubrication
  • Non-metallic bushings eliminate the possibility of corrosion and can be easily installed and will provide smooth grease-free operation

 

 

 

Turbo Cross-Shaft (TCS) Bearing Block Kit

(P/N M-01-1004-1)

 

Applicable to turbo-charged Piper Aerostar aircraft only. One kit is required per engine. Only compatible with OEM cross shaft P/N 300035-527 with replaceable end shafts (note: kit includes high-strength stainless steel end shafts).

 

Designed to save time and reduce maintenance with long-life polymer bearings. These advanced technology bearings eliminate premature wear of the cross-shaft and last longer than the OEM solution. Exhaust pressure pulses from the engine cause oscillations at the turbo’s wastegate butterfly resulting in vibration at the cross-shaft bearing blocks and lead to premature wear of the bearings and end shafts. With high-temperature self-lubricating polymer bearings securely carrying the turbo cross-shaft at both ends, without the need for any lubrication, premature wear is eliminated, and maintenance is reduced, saving you time, and keeping you flying longer.

 

 

An essential part of the Aerostar engine, the proper functioning of the turbo cross-shaft is critical. This kit helps resolve costly maintenance issues and lasts longer than the OEM components through the use of revolutionary design and self-lubricating polymer bearings.

 

Saves time

This TCS kit reduces the pilot’s need to actively manage the manifold pressures through the throttle levers by reducing worn cross-shaft bearings with self-lubricating polymer bearings.

Reduces maintenance

Due to its self-lubricating and high-temperature cross shaft bearings, which last more than 3x the OEM metal bearings, this TCS bearing kit reduces aircraft lifecycle maintenance costs.

 

All-in-one kit

Everything needed for one Aerostar engine. No additional components, lubrication, or parts are required.

 

Longer life

 

Based on field trials, the Marsh Brothers repair kit will last at least 3x longer than the OEM metal bearing and shows no signs of wear.

 

 

 

Hydraulic Accumulator Piston and Seal Upgrade Kits

(P/N M1030 and M1031)

 

Offers Aerostar owners the option to upgrade the hydraulic accumulator with a fully non-metallic piston and improved dynamic seals!

 

The non-metallic AeroTough® GF piston eliminates any chance of scratching the cylinder bore during normal operation. The Thorseal material will remain stable over a wide range of operating temperatures and will not swell, shrink, or bind. This Marsh Brothers kit also includes (3) parts, which is reduced from the quantity of replacement parts compared to the OEM design of (5) parts, ultimately simplifying the assembly process.

 

 

This upgrade kit includes a non-metallic piston made from their proprietary polymer AeroTough® GF, and state of the art Thorseals®, replacing the OEM aluminum piston fitted with a nitrile rubber o-ring, back up rings and a PTFE rider ring.
