(5)Automotive 4-stroke engine oil,grease
(6)Liquid packing
(7)File,sand paper
(8)Waste
2.NOTICE
(1) Use the standard tools properly.
(2) While disassembling the engine blower,memorize the locations of individual parts
so that they can be reassembled correctly.
Attach a tag to a part you are uncertain about its mounting position.
(3) Use boxes for keping disassembled parts in a group.
(4) To prevent any loss and wrong reassembly of screw bolts and nuts,try to assemble
each group of disassemble parts temporarily.
(5) Handle disassembled parts carefully,and clean them with wash oil.
(6) After removing gaskets,remove extraneous material clearly from the gasket placed palaces.
(7) Use an impact driver for a screw bolt and screw,etc.that are difficult to be unfastened.
(8) Use new gaskets when reassembling.
(9) After reassembling each of the rotatable main parts, rotate by hand to test it for
bad movements and abnormal noises.
(10)After the completion of reassembly, rotate the rotatable main parts by hand to test
them for defects and looseness.
