Date this National Disposer

used to

have an ISE PRO77, I thought that disposal was the S**T too! It was quiet, ate just about anything, and was fast. What I hated was the corrugated one-piece splash guard, and how it would erupt like a volcano sometimes, soaking whomever happened to be in front of the sink.
So I installed a vintage Waste King SS3300 and LOVED it. Still though I wanted a Viking and so I ordered one last year. Its ISE made, with a cast disk and ring. I modified the mount to the WK clamp mount using their 3 bold mount and splash guard.
Its ok, noisier than the ISE, and SLOW as molasses sometimes! However I do know it is chewing the stuff up and has never given me any problems.
Until last week.
I threw in two banana peels and hit the switch. The thing made noise and really seemed to be gnawing up the peels. However after a minute or so the sound did not diminish, so I stopped it and reached in. Here's what it did to the two banana peels:

this is the first tangle that came out... there was more inside yet!!
Never had any problems with banana peels before, I wonder why now these would not be chewed?

yes the Viking it to be replaced...I may just put my old ISE back in.

Jeff I can't beleave that.The only thing I can think of is that the primary Breaker bars are worn which dont make much sence.There the ones that stick up higher than the rest.There are some minor differnces though in mine than yours.I know that the Hammers are more rounded in yours than mine cause the grind wheel is a tad smaller mine has 48 teeth and yours has 45 but that shouldnt be a problem.Have you checked inside the unit?I had one like yours but it was the one with the button I dont think they were that differnt.I got rid of it about two weeks later cause I found the one that looks like the old K/a unit and got it for 200 Bucks so I didnt have alot of time to use the Ise made one.You ever thought about trying to attach the housing of your old W/k that fit to another one you have?Would your G.e. Fit your sink they are Fast as hell but loud.I know I ask you ? after? but there is a OLD True Value at the thrift shop you know who made that and is it any good I have it on hold but if its a Tappan or something I might let it go?Oh yea the Evolution Excel is VERY quite can barley hear it but they could have done better there is not much starting torque at all.

Jeff do you know what year Ise stopped using these grindrings.Also did they ever use Fixed Hammers with this Grindring?Every Ise I have seen now uses thoese cheap stamped crap the Excel is alot better but they could have used a W/k setup.

I am also disappointed that ISE stopped using very VERY durable and effective cast shred rings in favor of the LAME stampted steel ones that bend and corrode.the cast ones had GROUND cutters and the stampted ones do not.Disposers are getting CHEAPER made these days-that older National machine looks like a FAR better unit than any made today!-and it looked like the flywheel was cast iron or steel rather than zinc which wears and corrodes.Long live that National!

ISE

discontinued the cast ring in their household disposers about 1995 maybe?
Originally ISE's were all cast, disk and ring with fixed hammers. The last models to have the cast disk and ring were the old model 707 and 107, discontinued about 1980 and replaced by the classic.
I have not decided what I will install here yet, I also have an Anaheim Whirlaway I could reinstall, but those were so damn loud!

Never dated a disposer

Does dating trailer trash count?

I have found one Ise that still has the Cast Ring and its on the Do-it Hardware site. Here is the link http://doitbest.com/Garbage+Disposers-Emerson-model-E505-doitbest-sku-413712.dib Thanks for the info I have been wanting a OLD Ise but dont want to get that same s%$^ they have used forever what is really nuts was some guy bragging about his one year old Kitchenaid 1H.p. that he paid 400 bucks for when the Kenmore is the same.They know that most consumers are stupid for the most part.

Yea the Flywheel in my National is Cast-Chromium,Nickel,steel Same for the grindring.The rest is cast Iron the chamber is painted for some reason but the drain housing an't.I dont see how I could ever install the thing with out a floor Jack it is heaveier than my Old style Viking.the way it grinds is neat though reversing like that.It grinds a little better than the Viking also but that maybe cause it has what the Manual calls a High-bulk cutter in the center.I think I will just hold on to it though till I find my Maytag..
