worn water pump and worn aggitator cogs

leaned and propped washing machine back to get access to pump, removed hose clamps and hoses,removed retainer clips, old pump was stuborn to remove but was able to pry off motor with screwdriver. sanded rust off metal shaft,put on new pump,replaced retainer clips, replaced hoses and clamps. set washer in upright position removed aggitator cap, used 7/16' socket with long extension,unscrewed bolt, pulled off aggitator sleave, removed cog unit, replaced cogs, put sleve back on and tightened bolt. I had the machine outside so I hooked up a water hose and an extension cord, put machine on small load and tested machine . worked like new. also when i finished the test I had noticed earlier that my hose screen had a mineral build up, cleaned that by lightly scraping and used little rust inhibitor that also tackles scales. total time was about 30 minutes. Wife is happy now and I was rewarded later.
