Product Description

Flap Rollers Kits

FAA-STC approved for Beechcraft King Air 200 and 300 series aircraft
Self-lubricating flanged roller bearings that include an integral thrust washer. Rollers are made from the Marsh Brothers popular AeroTough® GF (grease-free) material, which eliminates the risk of metal-to-metal contact between the roller flange and the track side! Additionally, it will never seize. Unlike grease-packed rollers, the Marsh Brothers rollers will always rotate, regardless of OAT.

  • Simplified design
  • AeroTough® GF washer and roller
  • Self-lubricating
  • Operationally reliable!
  • Easy installation
  • Reduced maintenance costs

Benefits of AeroTough® GF material for Flap Rollers:

  • AeroTough® GF thrust washer is significantly tougher than the OEM Teflon!
  • AeroTough® GF eliminates the risk of metal-to-metal contact between the roller flange and the track side
  • AeroTough® GF will never compress, herniate, or become dislodged

Note: it is advised for all rollers to be replaced at one time for the initial installation.


Flap Rollers and flange thrust washers are available individually or in convenient kits, including a complete inboard and outboard kit, inboard-only kit, outboard-only kit, or individual flap roller kits. Part numbers and kit options are listed in the tables below.

Cleaning tip:

The rollers are highly resistant to incursion by debris, dust, and other particles. Should the ingestion of various particles become an issue, the aircraft operator can use the same cleaners, detergents, and solvents approved by the aircraft manufacturer. Marsh Brothers have performed compatibility tests with no detriment of the roller’s integrity.

FAQs

How do I get all the parts lined up and the bolt in place at the aft roller locations while working in the small flap hole?

We sell tool P/N 970 to facilitate the installation of the aft rollers and make the installation easier and simplified for this hard to reach location.

 

The handle of the tool makes access to the bolt hole in the small inspection opening easy. The pointed tool allows you to align the parts and easily insert the tool in the bolt hole. The next step is to push the tool back out of the hole with the bolt.

How do I determine the correct location for the different width flap rollers and the spacer/shim locations?

There are many different installations that were used for the different Cessna models. Please consult your applicable Service/Maintenance Manual and Illustrated Parts Catalog for the proper location for your specific aircraft.

Where do I install P/N MCSK100 flap roller service kit?

P/N MCSK100 Flap Roller Service Kit replaces the aft wide roller assembly, and only the aft wide roller. Please consult your applicable Service/Maintenance Manual and Illustrated Parts Catalog for the proper location for your specific aircraft, and the STC SA01074WI.

What is in the McFarlane flap roller kits?

Flap Roller Kits contain all of the rollers needed to complete one aircraft. Flap Roller Upgrade Kits include all of the components, forward wear washers (P/N MCS1450-3S10-032), aft service kit (P/N MCSK100), and hardware needed to replace the flap rollers and hardware associated with the rollers, along with Cessna SEB95-3 Rev. 1 for instructions to inspect flap support arms for wear.

What does P/N MCSK100 roller upgrade kit do?

The Cessna Service Bulletin SEB95-3 describes damage to the flap support arms from the edges of the rollers cutting into them as the flap rollers rotate. Cessna fixed the roller end wear problem on the forward roller locations by installing a thin stainless steel wear washer between the roller and the flexible flap arms.

 

The aft roller location is more difficult as it is up in the flap structure and is rigid. The flap support arms will not flex open for the addition of wear washers like the forward roller location. The aft long roller position has the same wear problem as the forward roller locations. Since there is not room to install a wear washer with the existing roller, McFarlane designed a roller slightly shorter in length that allows room for wear washers on each end of the roller. The wear washers are designed with a step in them to make them an assembly that is easier to install.

 

Note that the upgrades do not change the aft narrow roller and shims/spacers that control the flap lateral end play. P/N MCSK100 only replaces the unprotected long aft roller(s) on each flap. Replacing the flap arms that have excessive wear is very expensive and time consuming. MCSK100 stops any further flap support arm wear.

How do I lubricate my flap rollers

To lubricate use a lightweight oil. Lubriplate or motor oil works well. Lubriplate is a light weight, patroleum base, very oily grease.
