Adherence to guidelines for cleaning friction discs using F37, RAYFLEX®, and Cellulose friction material is essential to ensure acceptable service life for the discs. When cleaning discs, refer to the referenced literature and follow the guidelines listed below.
Chlorinated solvents, diesel fuel, kerosene and petroleum distillates, such as Stoddard Solvent or naptha, can be used to clean the listed friction materials. However, these materials are porous and incorrect cleaning materials or processes can damage them and lead to premature failure.
Follow these precautions:
* Do not use petroleum solvents hotter than 38° C (100° F).* Minimize the time that solvent contacts the disc.* Use towels or dry compressed air to dry the discs after washing.* Do not stack the discs after cleaning.Do not use any of the following types of cleaning materials or permit them to come into contact with the listed friction material. These cleaners will weaken the base material and cause it to disintegrate in operation.
* Water or steam.* Water based cleaning solutions (including Caterpillar Hydrosolv 4165 and Hydrosolv 100).* Freon.* Paint thinner.* Keytones, aldehydes (such as MEK and acetone).Caterpillar Brazil Ltd. (CBL) recommends hanging the discs vertically in the same order that they were removed in for extended storage. CBL also recommends protecting the stored discs with a plastic sheet in order to prevent moisture absorption and dust accumulation. Use the referenced guidelines when inspecting surfaces of plates and pistons that the disc will come into contact with. Plates and pistons with oxide deposits or resulting surface imperfections can cause damage to friction discs.
