Product review (5 stars): I have tight budget so although I skinned a knuckle it wasn't as bad as buying a new machine
Has been working for about six months now, I have tight budget so although I skinned a knuckle it wasn't as bad as buying a new machine!  Suggest watching the you tube videos for how to do this before deciding you want to tackle.  I found the videos to be accurate but the actual effort at certain parts is more than shown because parts are likely to have been in places for 10, 15, 20 years.  Hardest part was believing that I did it right and that the new seal would actually work.  But so far I'm happy, especially when comparing to price of new machine.  Do check that you don't have other leaks that would make this repair a frustrating waste.
