NOTE: Special care and cleanliness are essential for correct disassembly and assembly of the transmission, differential and other gear components. Failure to follow these procedures may result in early hour wear and failure. Thoroughly clean the exterior of the transmission and differential prior to any disassembly. Any exterior dirt which would enter the transmission or differential could cause damage and failure of the unit. Disassemble and assemble the unit in as clean an area as possible. It is essential to replace all parts which have become defective along with all O-rings and seals. All machined parts showing signs of scratches or other wear must be replaced. The cavities of the housing, especially the corners, must be carefully cleaned and rinsed. If the disassembly and assembly is a result of a serious breakdown, it is essential that all portions of the unit be cleaned and flushed to eliminate any broken parts or metal particles. Carefully lubricate all parts during reassembly. Cover all faces of housings and covers, which must be oil-tight towards the outside, with the proper sealing compound, gasket or O-ring. Prior to operation, insure that the unit has been filled with the proper lubricant. Consult the Operation And Maintenance Manual for the proper levels.
