This is part of an ill-maintained water pump on a Diamond Pacific Genie. Improperly lubricated and scored to the point at which it will never play the violin again (and won’t spin freely in the pump either). Lubricate those pumps, peeps! 30W oil, not light machine oil. These things really need regular oiling and leather replacement. DP screwed up royally putting this pulley next to the 280-grit wheel in the dirtiest part of the machine! No doubt rock dust got into the unit thanks to bad maintenance and just scratched the stew out of that shaft over time. Just moving the pump to the right-hand side of the machine would in my opinion be a big improvement.

The steel frames that are attached to either side of the Genie's motor appear to be identical (they both have the pump attachment holes). I'm wondering if it's possible to switch the two arbor sleeves so the one with the pump pulley is on the right (cleaner) side of the Genie. Then I could put the pump on the right side where it will not tend to get in contact with nasty rock dust. Hmmm...?
The only drawback to this (if it's possible) would be that I couldn't spin off the right-hand wheels and put the box cutter or trim saw on the Genie. But since I have neither...

I would think the best way to find out would be to call Don at DP and ask him if it's doable.

I've had the left-hand spindle off before but can't remember if the pulley was part of the spindle. I've talked to Don before and got some really "gee-whiz" info from him that seemed crazy but worked (story for another day).
That would sure be easier than stealing a Genie from a student and tearing it down in the classroom!

The only thing I really dislike about my Genie is the finicky pump. Even when maintained properly it never delivered sufficient water. I solved the problem by simply adding a geyser using an independent water source (my household water heater). Works like a charm and saves lots of frustration. I had to add a drain line to a 5-gal. bucket under the bench. I bought a cheap submersible pump and pump the water in the bucket to an outside drain.

bitterbrook- Great reminder! (and visual) I am always afraid that I use too much oil. I use 30 weight about every 6 months. Don't know what that equates to as far as cabs made, but that's what I've been doing. In your opinion is that too much or too little?

I believe they recommend 30 wt. NON detergent oil now. They told me the detergents used in automotive oil gums up the pumps. I had a really long conversation with their purchasing manager (also named John) on behalf of a club workshop manager having problems with newer vintage Genie pumps. Another club uses aquarium store air pumps as an alternative. On my Genie, I always placed both geysers under the wheel I was using to flood the wheel. It made it a little messier though.

I really despise the pump on my DP pixie. Constantly clogging, have to breakdown the entire machine to get at the pump, disassemble, clean, replace, repair, re-assemble...too much downtime.

I use both geysers under my wheel, too. When say non detergent oil, what would that be? I am using automotive motor oil.

My belt broke getting tangled up with a geyser hose. I have the replacement kit but don't want to deal with frozen left side. The Genie pumps always worked much better than my other pumps and heads. I use two aquarium pumps with 3 heads and put the heads in my genie trays. They provide adequate water. Two genie geysers under a wheel is better.

Couldn't get to a phone so I tried switching the pump to the right side during a class demo on the Genie. Physically, everything made the switch perfectly. But when I started the motor, the pump puffed out air a few times into the reservoir, then POW water started POW shooting out POW of the bottom of the pump!
Eeek!
It's a piston-powered pump, for crying out loud. Does a piston care whether the camshaft rotates clockwise or counterclockwise? Nope. Discussed the problem with one of my students (a master plumber) and came up with zip.
All we could figure was that the problem originated with the oiling tube insude the pump. Any thought?
I'll try Don again when I get home. Can't waste any more class time.

Note that I used the Tractor Supply link, as there must be a store near you. It can probably be found at other places as well, but this was one of the first links that came up for me.

4/30/19 EDIT: Just any old Medo pump may not work. It has to have sufficient air output. Too little air and it won't push enough water through the geyser. The one that I installed (shown below) has a rated output of 0.71 cfm, which works very well for my Pixie. My Medo pump's model number is AC0201A. Be sure to research the model number and air output for any pump you may be considering. I will write up a separate tutorial with additional information.
Here's an option that may be of interest. When my Pixie pump performance started to go, I decided to find an external pump rather than repair or replace it. I purchased a Medo pump on eBay. It's a high quality Japanese brand, and the one I got came out of a hospital bed/cart. That means that it meets FDA medical device requirements. And that means that even though it's used, it's going to outlast me. It really moves water through the Diamond Pacific geyser! I mounted the pump under the Pixie's housing, wired it into the Pixie's switch, and added an input filter bag I made from a HEPA vacuum bag. Here are some photos. Also, there are quite a few Medo pumps available on eBay.

Most auto parts stores should carry non-detergent oil. They were common back in the old days. If you put detergent oil in an old car that only ran the older non-detergent oils you ended up with massive oil leaks everywhere. Detergent oils keep engines from building up sludge by keeping everything suspended in the oil. You can call DP for exact recommendations. They were going to start selling oil for te pumps but I don't know if they have it yet.
