Product Details
McFarlane offers a basic flap roller kit or an upgrade kit to address flap arm wear problems. Each flap roller kit contains enough components for one aircraft. All components are also available separately.
Basic kits include: rollers, bushings, shims, spacers (where required), and a copy of SEB95-3 (as applicable). The basic flap roller kits do not include the wear washers as required by Cessna SEB95-3 Rev.1 for the forward locations.
Upgrade kits include: rollers, bushings, shims, spacers where required, MCSK100 Flap Service Kits, wear washers, a copy of SEB95-3 Rev 1, and hardware (nuts, bolts, washers).
- Part numbers for the upgrade kits end in “U”
- SEB95-3 Rev 1 is not applicable to 172R,S, 182S,T, T182T, 206H, T206H, 208, 336 and 337 aircraft
- Flap upgrade kits contain nuts, bolts and washers for several aircraft models. The installer must determine the correct nut, bolt and washer combination for each installation.
Make installation of the aft flap roller, bushing and washers easy! Go to the 970 Flap Roller Installation Tool for more information.

Frequently Asked Questions
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.
