McFarlane Roller (Seat Large) - MCS1704-1

McFarlane Aviation FAA-PMA replacement seat parts were developed to assist in complying with the parts replacement requirements of A.D. 2011-10-09. This A.D. requires the periodic inspection and replacement of the seat components of the entire Cessna light aircraft fleet. Our parts are direct replacements for the wear related seat components. For convenient tools to inspect your seat rails per this AD, see the GAUGE SR1 seat rail wear gauge and TOOL110 seat roller housing gauge.McFarlane seat parts are superior to O.E.M. parts in many ways. Our rollers are fabricated from molydisulfide filled nylon for improved strength and self-lubrication. All rollers are fully machined from extruded stock for a finer surface finish and higher strength. McFarlane bushings are machined from alloy steel for longer life and greater wear resistance. Our wear washers are made from a super tough acetyl plastic and have far better wear properties and resistance to aging. McFarlane seat components will outlast the original parts.The seat related replacement parts are not serial number specific as the type of seat installed in the aircraft was optional when the aircraft was ordered from the factory. A common seat configuration is the pilot seat being "articulating" or "infinitely adjustable" while the co-pilot seat is the "standard" or "vertically adjustable style".The most positive way to ensure you choose the proper seat kit for your aircraft is to measure the rollers:SEAT-KT-1: Roller diameter approximately 1 3/8”This kit is used with the “infinitely adjustable” or “articulating” seats installed in the Cessna single engine aircraft from 1963 through 1986. Two adjustment crank handles identify this seat. The backrest angle is adjusted with a crank. It is also used with some 336-337 series aircraft. The SEAT-KT-1 contains the same components as four of the Cessna 1714000K200 kits. All seats in the 177 Cardinal will use the large seat roller and require this kit. These parts are not used on models 150-152. (8) MC1714000-22 Washer(4) MCS1704-1 Roller(4) MC1414104-54 BushingSEAT-KT-2: Roller diameter approximately 5/8”This kit is used with the “Standard” or “Vertically adjustable” seat installed in Cessna single engine aircraft from 1963 through 1986. This seat is identified by one or no adjustment crank handles. The seat back angle is adjusted with a lever on the side of the seat back. It is also used with some 336- 337 series aircraft. The SEAT-KT-2 contains the same components as four of the Cessna 1414100-212 kits. These parts are not used on models 150-152.(8) MCS1554-1 Washer(4) MCS1551-1 Roller(4) MC1414104-54 BushingSEAT-KT-3: Roller diameter approximately 7/8”with no wear washers This kit is used with all seats in the Cessna 150-152 series aircraft and all Cessna single engine aircraft built before 1963. A welded steel tubing seat frame easily identifies these seats. It is also used with some Cessna twin engine aircraft.(4) MC0311310 Roller(4) MC0311586 BushingObsolete roller 1964-1965: Cessna aircraft manufactured in 1964 and 1965 had a spool shape roller with a smaller bushing. Use SEAT-KT-2 to replace this style roller. The complete kit must be used, as the bushing size is different.
