To answer some of the points raised here..in no particular o
To Tomturbomatic, there have been upgrades to the series of machines, you friend now has, check pages 16 and 18 for the washarms that Hobart has used in the LX series undercounter machines.You will see how the separate rinse arms have also changed going from a smaller version of the embossed arms to the current tubular style with tiny spray holes for the water to rinse the dishes and glasses.
I heard from my contact at Hobart tech support and he offered the reasoning that the change away from the 4 way arm was to create a more effective cleaning pattern on the dishes. the holes were made smaller which increased the pressure of the water on the dishes and washed them in a more direct pattern instead of "flooding" them with water as we know the 4way arm and the big old blue arms used to do.
The new style arm also does turn a bit faster than the 4 way but he did not offer an actual rpm number.
Interestingly, the newest machine Hobart makes, the AM-15 series single tank machine also now has washarms with smaller holes in them and the tubular rinse arms. The wash results were very much improved with the smaller wash nozzle size and cleans way better than the older arms we used to have in the previous series units. The older ones really flooded the wash chamber with torrents of water.
As far as making the change to a standard K/A unit, the kit from Hobart would be well over 200 bucks and will only fit into the 18,19,and 20 series. The decision would have to be yours, Gansky. The kit does include the washarm, the upper and lower pump housings, a new larger volume shaft seal/drain impeller and a new stainless steel filter which you may have to modify to fit your unit. Namely, remove the very bottom piece which would curl up in the sump. This would interfere with the heating element and temp sensors in the 19 and 20's. It works just like the originals and the little blue or black coarse filter remains in place. I would have to check availablility now since many of the specific parts and numbers have been changed so they may no longer offer the kit anymore.
All the individual parts would be available and if you want,I can price them out for you.
(Admittedly, I did install one in my KDC21D machine which turned it into basically a 20 series as the normal wash pump top was not usable so there wasn't that extra filtration of the water. But it still gave great results.) But that machine is back to its original state and collects dust in the garage.
The link here is for one series of machines and Hobart also has a more simplified machine which is basically the old WM5 series retooled for more strength and durability and is based on the KD 18 series but with the newer pump enhancements. I will attach that to another post.
