i am so glad you got that
machine! it is basically new, preserved all these years since around 1975! just waiting for you to grab it!
that rust is probably just a little surface rust, i have a bunch of kd-17's and not one of mine has any major rust problem that threatens it's tub life! and some of mine are not in good condition, definately not 'new' like yours! all of mine except the kdss-17a with the stainless tub had that bit of surface rust in the sump like yours.
100 bucks was a great price for a kds-17a in that condition. new like that 300 would not have been unfair in my mind.
as you probably already know you can get a pump seal from hobart, larry in cleveland has em too. they are readily available. it is my guess a seal is the only part for that machine you will ever need and probably not for about 30 years!
what a beauty! i was gonna call on it but i'm so glad i cannot! and yea, i love that new hydrosweep! i recently bought a new hydrosweep off e bay and they look so clean, shiny and black before they start to discolor from use!
what a catch!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
