Several posts just say order the parts numbers and do not mention the HF unit. It also says to make a phone call. Here's the info again.

Rikon - 877-884-5167 - ask for parts, do NOT talk about your HF-DC, state you need an impeller for a 60-200 DC, part #22 for the impeller. Part #26 for a new bolt and part #27 for the "spring washer". You can use the old bolt and washer - I did - but bought the new ones anyway [why you ask - because I am that...]. Total cost for all of it - $120.27 including S&H. Download the Rikon Manual for a 60-200M3R.PDF and check for yourself

The more I do, the less I accomplish.

Good point Mark. Unless the composition of water is not stable and the laws of physics suddenly change then there is absolutely nothing that can go wrong with it, unlike a mechanical meter. I'm a power engineer and many of the ones used in my trade also use a fluid and but as Rob pointed out earlier, they are sloped so that changes are easier to read.

Re: needing a serial number to order a part: if anyone near you sells Rikon go take the number off a new one. Not exactly the most ethical thing to do but I'm not sure what they have against selling impellers.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

I'm guessing they don't like you paying $150 for the HF (on sale), plus $120 for their impeller, for a total of $270, instead of $400 for whole the Rikon DC. Aside from the impeller, paint scheme, filter bag (which you should replace with a Wynn), it's hard to see a difference between the HF and Rikon.

On the other hand, I would think they make some profit off selling just the impeller.

I would think jumping from a 10 inch blade to a 12 inch on a DC should make a huge difference.

I bought mine a little over a year ago. I too had heard that I would need the serial # off of a Rikon DC to complete the order. It sounded like a bunch of nonsense, so I called and I asked when ordered. The person that I spoke to, chuckled and said "We've heard that too", then they charged me $120.00 and sent me the impeller.

Guys when I seen the difference in size with those two impellers , I didn't think the larger one would fit in the same chassis?
Seems kind of strange that they left all that excessive room in there . I guess if you want a model with more output , they just name it differently and have that bigger impeller installed ?
Wonder if my General DC can have a larger impeller installed?

I donít always insulate , but when I do .
Ok ,I never insulate

In one of the many threads I've read on this, someone pointed out that a smaller impeller would allow bigger chips to pass through. I doubt that's what HF's "R&D department" was thinking, but I still probably wouldn't change the impeller if I didn't have a chip collector.

That makes sense then . They leave extra room for the chips that may go threw .
I wonder how much cfm you loose with a chip collector?

@furboo

I would be very interested in the readings for the Wynn vs. the original filter bag, including the specs for the bag.

Thanks for the post, very informative.
