Rebuilding a Hoshizaki Ice Machine Pump

[@richkellow1535]

I have the utmost respect for a conscientious tradesman.....10/10.

[@Halligan142]

Thank You

[@r.mccullough6197]

Got my vote on the electrical schematic reading video(s) as well....as always great video Greg

[@engelbob8402]

Nice video Greg. I vote yes on giving a lesion about electrical schematics.

[@gadget73]

I have a couple motors at work designated as emergency spares. They were pulled for noisy bearings, and put back on the shelf with new bearings in case I need one. They're reserved for low stress areas. The new motors go into the spots where things get destroyed.

[@c185pilot3]

Very interesting Greg...one vote here for the electrical schematic video when you get to it. Thanks

[@dhyanrules3]

You missed a part, a very important one at that. The rotary shaft seal from the head of the motor. That is what, I believed, caused the water the go to the bearings after the mechanical seal failure. Also greasing everything with non water soluble grease goes a long way in terms of preventing a future problem.

[@RGSABloke]

Hi Greg, really enjoyed this video, please keep them coming, it's all great info in the bigger picture. Thanks for sharing. Kindest regards. Joe.

[@StraightThread]

Interesting repair, Greg. Thanks for sharing.

[@madcapmartin1]

i love your machining vids, but i do miss the hvac vids.... more please......

[@Darryl603]

Turned out to be a pretty easy fix. Good job! It's worth more to you to have it on stand by...

[@cmonster6]

I would love to see a vid on wiring capacitors and why they are used ect.

[@jonminnella2168]

great video you can never go wrong with a spair back up pump custmer will love you for it good job

[@Volcker1929]

Thanks for the great videos, it would be great to see more HVACR videos.

[@olivier2553]

I would have needed your skills to read a schematic yesterday: after moving the fridge, the power lead was pulled of. I opened the cover to reattach the cord and was very surprised to face a rat's nest of wires. I had a tiny schematic, all written in Thai! I manged to figure out that all the red wires should go together to one lead of the power cord, and all the grey one to the other lead. But man, I was really unsure of what I was doing!

[@swarfrat311]

Greg, Pump it up! (LOL) I've been interested in electronics and electrical stuff since I was a preteen. I know how to read schematics and wiring drawings. When I serviced professional woodworking machines, most were made in China or Europe. The conventions on their wiring drawings are totally different from what I was used to when I serviced direct mail equipment (US made). I used to carry repaired control boards, motors, etc. for the reasons you stated. Some places ran 16 or 24 hours a day. Thanks for the video. Have a good one! Dave

[@LIHUI-MOTORS]

The motor was made on China

[@marceltimmers1290]

Hi mate. I don't know for whom those bloody ceramic seals were designed for but I have seen several of them that have leaked into the motor. They are a pain, but are wonderful for the replacements pump sales. A lot of pool pumps are also using them.

[@davidsu9091]

good job. I learn a lot from this viedo. Thanks

[@MookieMan1]

All of your videos are great. How's things going with the new house? Get to use the snowblower?

[@Halligan142]

Yeah. We had a few storms of over 12" but hasn't been too bad. It has been cold though

[@polishtheturdmickelson5473]

Nice video 142 Halligan. I subbed to your channel.

[@scrout]

You would think they would orient the pump below the motor for no leaky along the shaft?

[@vernmitchinson7933]

You mentioned that the drain hole was on top so I am wondering if rotating the pump housing 180 degrees would put the drain hole on the bottom?

[@Volcker1929]

Vern Mitchinson it could put the motor leads in an impossible to connect spot.

[@Halligan142]

Yup. There's a bracket that bolts to the motor then that gets screwed to the wall. The motor sits between two panels and the leads need to go through a hole into a connector

[@tigermania13]

Hi Greg, have a hoshizaki am50bae ad is not making ice, look at the control board it ok; noticed that the water doesn't get up to the ice chute. Pump motor is the next step but to get it out; do I need to remove the ice chute from the top down to the water tank? Do you have any suggestions? Any help will be awesome

[@goldsearcher55]

Yes loved the video please do more! HVAC is very interesting stuff

[@shawnmrfixitlee6478]

right on man , Gotta save the parts the ya can ..Thumbs up !!

[@undertalesans4758]

Why you skip when you pull out the fan? Is the difficult

[@kurtarmbrust]

All the moving parts on that pump have been replaced. Give them a 90 day warranty and a discounted price and everybody is going to be happy. Show us more!

[@micbanand]

I would give a 2 year warranty half price of a new one

[@markgilbert9930]

"Shit the bed" Outstanding..

[@gbowne1]

Ever do Cornelius/ServEnd/Lancer type Soda fountains? the one I have I got because I got tired of SodaStream. it needs some work and gotta find the parts.

[@Halligan142]

The dispensers themselves no, but Pepsi at one point used Cornelius Ice machines on their bins. Absolute POS

[@kenapotheosis7026]

I have this motor in my store and need to replace the bearings. Where can I find them?

[@balisticsquirel]

If you do vending machines, maybe you can help me figure out what i found. I scrounged a bunch of parts from a metal scrap yard which must have come from some or other vending type machine. Iwaki bellows pumps; an impeller pump similar to yours but smaller; and this other thing that i don't know about. It's a stainless steel cylinder with two piping inlets and two outlets (not shared, ie two separate flows) and two wires running into it. Plus one drainage nipple. Otherwise entirely sealed. Maybe 10" long and 3.5" diameter. Oh, and it has what must be thermocouples bound to the outside of the cylinder which the wiring goes through. I figure the wires will be to and from a heating element inside of the cylinder? But is there anything more to it than simply being a water heater? Like could it need both water lines flowing when on in order to not fry the element? Does one line exchange heat somehow? Is there a name for this thing? Cause i can't find them in google searches using the terms i can think to try. Cheers.

[@tom7601]

balisticsquirel Probably a coffee/hot chocolate vending machine. The cylinder would be a tankless water heater. Just guessing.

[@balisticsquirel]

Thank you.

[@LIHUI-MOTORS]

Maybe i can help you. Pls sent the picture me .

[@rajeshkumar-ob4fr]

Sir can you water pum use it

[@2davydo]

I am Working on a Hoshizaki KM 1300 MRH Model that Beeps 2 time a second. Cleaned the float switch was all crusted up with scale, Also replaced 1 txv. It was leaking and letting out hot gas or cooling it off During the harvest cycle. Works fine during the day but at night after closing the store it will shut down and beep till mourning and the customer has to reset the board. have charged it with 10lbs of R 404a, Checked the thermocouple not shorted or open. Any advise. Thanks in advance.

[@Halligan142]

That thermistor has to reach 48 degrees to trigger unit to come out of defrost. If that suction line temperature fails to reach that in 20 Min or less 3 times in a row you'll get that code. There could be a couple things going on. The thermistor itself could be bad and not reading correctly, you could have a low refrigerant charge, hot gas valve may not be opening all the way, ineffecient compressor. Grab the tech pocket guide for 404a units. You can get a printed copy or find it online. It will give you resistance readings you should be.getting at specific temperatures from the thermistor. It will also give.you some.basic pressure readings you should be seeing during all phases of ice production. Also give a quick read over hoshizaki tech tips vol 149

[@2davydo]

@@Halligan142 OK thanks. i have downloaded the entire book from the site and printed out the part with the resistance readings. Also the part about the dip switch settings. was thinking if changing dip sw 1@2 to on on the board if that would help.

[@jimmyfiggs6293]

I wanta learn more!!!!!

[@davidsu9091]

I open the motor and get two bearing 292 and 6200 but there is a #11 mechanical seal which I do not know where I can buy that rubber seal. I went to the Grainger but they do not carry this product. Anybody can help me? Thanks.

[@markdavie2224]

I can’t get the hosh water pump apart, can you describe your method. Thanks

[@Halligan142]

You'll need to clean the face if it's as corroded as the one in the video. Take a razor and find the seam in the face. Use a nice penetrating oil like kroil on it. Tap on the rear shaft with a brass hammer where the cooling fan mounts to and you should start to see it move. Besides that everything else is in the video.

[@printcloud5804]

I am trying to take the fan off. But the screw in the fan is stuck. How to remove the screw?

[@LIHUI-MOTORS]

pls buy new motors

[@NC-oc3ld]

You're a ifesaver! Thank you so much. +1 for schmetic reading video

[@bowen1969]

nice video

[@r3dl3ad3r]

Hoshizaki shaft seal kit - 4A3820-01

[@mattagee8104]

Good job

[@throttlebottle5906]

I wonder if someone else rebuilt it before

[@Halligan142]

No it's original. I installed the ice machine.

[@robpeterson4742]

Good job I like the video.

[@RGSneaker]

I also thought of commenting the 180 degree bit, but I now have a better idea: Offer a service job to just replace that leaked gasket before the cost skyrockets

[@OcRefrig]

Good Vid.

[@tom7601]

You could probably 3D print a new impeller.

[@rektalmort]

Lets watch this

[@fernandovazquez5296]

I CHANGE THE BERING ALL TIM ON MY ICE MAKER IT LAST ONE YEAR IT COST 6 DOLLARS THE MOTOR COST 700 HUNDRED DOLLARS

[@markdavie2224]

How specific do you break pump apart to bearings?

[@LIHUI-MOTORS]

Sir , i am producing this motor. if you want. pls contact me.

[@deansheridan]

Tsk to me about the bearing

[@motoerhead85]

first xD
