1. INTRODUCTION
NOW, WE ARE GOING TO INTRODUCE THE REPAIR GUIDE FOR THE
CLUTCH SPRING OF GEAR MECHANISM IN THE FULL AUTOMATIC
WASHING MACHINE.
FIRST, I WILL GIVE SOME INFORMATION TO YOU. WE HAVE BEEN ANALIZED
THE FIELD CLAIM ESPECIALLY FOR THE GEAR MECHANISM DURING 4 YEARS.
AS A RESULT OF THIS ANALYSIS, WE FIND THAT THE MAJOR
DEFECTIVE COMPONENT IN THE GEAR MECHANISM WAS THE CLUTCH SPRING.
AS YOU KNOW, THE REPLACEMENT OF GEAR MECHANISM IS VERY HARD JOB.
AND THE REPLACING COST IS ALSO VERY HIGH. SOMETIMES, SOME CLIENT
COMPLAINED THAT POINT.
SO, WE DEEPLY CONSIDERED THE CLIENT'S GRIEVANCE, HOW TO REDUCE
THE REPLACING COST AND HOW TO REPLACE THE GEAR MECHANISM SO EASILY.
THEREFOR, WE ARE GOING TO GIVE SOME MEASURES TO REPLACE THE
GEAR MECHANISM. IF YOU UNDERSTAND WHAT I AM SAYING AND FOLLOW THE
PROCESS WHICH I WILL EXPAIN NEXT PAGE, YOU CAN SOLVE THIS PROBLEM.
ALSO, WE ARE GOING TO EXPLAIN THE WAY TO CHECKING METHOD OF THE
CLUTCH SPRING DEFECT,NAMELY, WHAT SITUATION IS CORRESPOND TO
THE CLUTCH SPRING DEFECT.
LET ME EXPLAIN ONCE MORE, THIS GUIDE IS ONLY FOR THE CLUTCH
SPRING DEFECT OF THE GEAR MECHANISM IN THE FULL AUTOMATIC
WASHING MACHINE.
FINALLY, WE HOPE YOUR JOB AND BUSINESS WILL BE BETTER THAN NOW.
THANKS.

PROBLEM
1) THE LAUNDARY IS IN THE SPIN TUB UNEVENLY WHEN JUST STARTING SPIN PROCESS.
2) THEREFORE, IT CAUSE THE SERIOUS NOISE AND VIBRATION WHEN WASHING
AND SPINNING PROCESS
OR SUPPLING WATER IRREGULARY WHEN SPINNING PROCESS
AND CAUSE SHORT OF SPIN PERFORMANCE.
CHECKING METHO
IN THIS CASE, YOU MUST EMPTY THE SPIN TUB FIRST.
1) TO CHECK THE REVOLUTION OF SPIN TUB. IF THE SPIN TUB DOES NOT REVOLVE
AND ONLY THE PULSATOR IS TURNING, THAT IS CLUTCH SPRING DEFECT.
2) TO CHECK THE SPIN SPEED(RPM) BETWEEN SPIN TUB AND PULSATOR.
IF YOU FIND THE DIFFERENT SPIN SPEED BETWEEN SPIN TUB AND PULSATOR,
THIS IS ALSO CLUTCH SPRING DEFECT.
