Product Details

Turbo Cross-Shaft (TCS) Bearing Block Kit

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.
