McFarlane Cessna Shaft MC1752078-4 FAA-PMA Approved

Description

Unique Elastomer Bearing Replaces Needle BearingElastomer bearing is assembled with tension between the mating surfaces. This tension prevents micro-movement and its related metal erosion. The bearing contact area that transfers vibration motion from the heat box to the butterfly shaft is hundreds of times greater than that of the original needle bearing. This large surface effectively prevents localized metal erosion.Absorbs shaft and butterfly vibrationEliminates needle bearing failuresIncreases service life of all componentsDirect replacement for original partsProven Design• Tested to over 700,000 cycles while exposed to avgas, heat and vibration without any change in performance• Extremely rugged and wear resistant in high temperature and fuel environmentsConvenient• Discontinued part numbers through the factory are now manufactured by McFarlane• Also available in kits containing the shaft, arm, bearing housings, monel rivets, and roll pinDownload the Carburetor Heat Box Application in PDF.*Partial model eligibilityPartial model eligibility
