(Sheet 1 of 1)
Before cleaning, protect rubber items (hoses, boots, electrical insulation) from cleaning solutions. Protect them with a grease-proof barrier material.
Remove the rubber part if it cannot be protected.
Any cleaning method may be used as long as it does not damage a part. Cleaning is necessary so that parts can be checked. Rusted paint areas must be
stripped to bare metal before repainting.
RUST OR CORROSION REMOVAL
Rust and corrosion can be removed with a wire brush, abrasive cloth, sand blasting, vapor blasting, or rust remover. Use buffing or a crocus cloth on
highly polished parts that are rusted.
Remove shields and seals from bearings before cleaning. Bearings with permanent shields and seals must not be cleaned in solution.
Clean open bearings by soaking them in a petroleum cleaning solution item 2 Appendix C. Never use a solution with chlorine in it.
Bearings should stand and dry. Do not use compressed air to dry. Do not spin bearings while they are drying.
