7. DISASSEMBLY AND ASSEMBLY                          

7-1 PREPARATION and PRECAUTIONS 

(1) Be sure to memorize the location of individual parts when disassembling the generator so that 

the generator can be reassembled correctly. Tag the disassembled part with the necessary 

information to facilitate easier and smoother reassembly. 

(2) For more convenience, divide the parts into several groups and store them in boxes. 

(3) To prevent bolts and nuts from being misplaced or installed incorrectly, replace them 

temporarily to their original position. 

(4) Handle disassembled parts with care; clean them before reassembly using a neutral cleaning 

product. 

(5) Remove the battery before disassembling the generator. (Electric start models) 

(6) Use all disassembly/assembly tools properly, and use the proper tool for each specific job. 

(7) Be sure to attach the foam rubber linings inside the covers on their original position when 

reassembling the generator. When deformation or damage or falling-off of foam rubber lining 

is found, replace it with new parts. Failure to do so will result in poor performance and 

durability of the generator. 

(8) Bind the wires and fuel pipes using wire bands as they have been done in original 

configuration. 

NOTE: As to detailed information for servicing procedures on the engine portion, please refer to 

Subaru engine service manual for "EX35/40".

 

7-2 DISASSEMBLY PROCEDURES 

7-2-1 FUEL TANK 

(1) Shut the fuel strainer and discharge fuel 

from carburetor. 

(2) Disconnect rubber pipe from the strainer. 

(3) Remove the fuel tank. 

M6 flange bolt . . . 4 pcs. 

Rubber (tank) . . . 4 pcs.
