This Special Instruction contains assembly information for the installation kits that are required when you install turbine precleaners in certain applications. The kits allow the installation of turbine precleaners on products that are equipped with dust ejector systems. This Special Instruction includes the following topics:
a general procedure for removing the existing parts
instructions for assembling the installation kit and precleaner
a checklist for testing the restriction after installing the precleanerDo not perform any of the procedures until you thoroughly read the information in this Special Instruction.Refer to the appropriate module of the Service Manual for complete disassembly and assembly information.Refer to PELE0844, "TURBINE PRE-CLEANER ADAPTER KITS AVAILABLE FOR MACHINES WITH DUST EJECTORS" for the diameter of the air inlet pipe and the diameter of the air cleaner inlet.Removal of Existing Parts
Remove the dust ejector hose from the dust ejector system. Remove the dust ejector hose from the muffler.Note: If the dust ejector hose connects to the exhaust extension, proceed with Step 2. If the dust ejector hose connects to the muffler, proceed with Step 4.
