- What will you do if you have a TXV trouble and you do not have anymore spare onboard????
In this video you will learn the last resort that you need to do in case you have this kind of situation of not having available spare onboard.

So it will work as a Fixed Metering Device. Awesome!!!
You are smart man. I would never have believed that would work
This is genius! I would never thought of this. If bulb loose charge, you can make artificial opening force with the bolt. Will come in handy on emergency situation.
Thats genius level work there!
Had TXV fail shut so I could not pump the system down to replace it, so cut the sensing bulb off and made a connection to the capillary and used nitrogen to pressurise the bellows and open the valve.
Hey I’ve done that too but would you be able to use like 45% solder on that stainless steel line?
Regular soft solder will stick to stainless if you use a soldering iron and flux. If you use a torch, the instant the flame hits the stainless it will oxidize and the solder wont stick.
@@EldonJohansen 15% silver solder solders stainless steel perfectly. Give it a go
@@edwardtsang3243 it sort of works but the phosphorus in the rod makes a brittle intermetallic bond with the iron.
5:11 - Thanks for the idea. The only thing I will change from your method if I need to use it is use a bottoming tap instead of the one you show here. I am new to refrigeration so your videos are effective educational tools for me!
Thank you for the knowledge, success for "leckyjake ....." ... Pekalongan, Central Java, Indonesia attended
It's really rare that a Danfoss TU goes bad. But this trick i have never seen. Being in this trade for 10 years.
У нас говорят "голь на выдумку хитра" 👍
Nice. Turns it into a piston. Probably have to baby it though but good in a pinch
Hahaha the first answer I said was the same thing tap and set screw.
Best is TXV with manual set screw for emergency
But great video
Nakakasawa din pagbabarko lek. I only have 4 yrs international experience as ETO. then 1 year sa shipyard in batam indonesia and the challenge was intense kung shipyard vess commissioning. At 28 yrs old i retired as ETO and naging flagstate surveyor dto sa Pinas, also im an ISM Auditor. i keep watching your videos because it brings back my memories at sea. Now im on a campaign to help develop our local shipping to something better like what i saw in other countries like indonesia, that some how our local ships would be at the same standards and quality like an international ocean vessels.
Good solution to this problem !
What a great idear in a emergency.
I have heard of people braising a port onto the TXVN, putting in high-pressure nitrogen
informative video good job lodi
Muito obrigado, tank you.
Keep up the good work my brother
Nice ,very informative
Leckyjake can u make a stepbystep vlog on pumping down reefer and filling of refrigerant pls. We dont have electrician onboard. This would help us alot. Thanks for those really helpful and important videos. More power Lexkyjake
Should be able to front seat the king valve. And have your manifold gauge hook up to the low side to see the pressure or if the unit has a display that shows data and lock it on suction pressure.. once the king valve is closed. The unit will start going into a vacuum.. storing all refrigerant in the receiver tank. Once suction hits 0. Shut off the unit... it is now pumped down. And you can repair on low side lines or do repairs or remove compressor. Once unit is repair. U can front seat the discharge valve. And RR filter drier. And pull a vacumm @-29/30. Then can charge accordingly, utilizing the vacuum that's held in the system to pull the refrigerant in... once charge, back seat the king valve. Start unit. Purge the king charge line into lowside for acouple seconds... that line is now good to be taken off.. them back seat low side valve... unit is now in normal op. Hope that helps
Good knowledge my bro.. thanks 👍
Great videos..
Keep them coming ..
Steve Sheffield UK ..
you can't imagine how emergency situations may be handled cleverly onboard.
Nice solution bro
Thx, from Romania!!!
Very cool boss , god bless you👌
Very good work
That’s a good workaround for emergencies! Shame they’re not TEVs with removable power heads as you could keep a pre-made emergency power head on standby without having to unsweat 👍🏻 top video
There ARE more in refrigeration application's
5:11 - Thank you for your input. You just made this artificial sensing bulb idea even more valuable to me (see my comment above)! I still have two Sporlan valves that were replaced recently (one was a capillary tube rub out so the valve is likely still good), which I will modify to keep on hand.
Wow! It's a amazing idea. 👍
Step one. Don’t use junk danfoss valves. Install a sporlan. Buy rebuild kits and screens. Repair made. Good tip though.
Very cool! Just make sure that if you put a stainless bolt into stainless use some antisieze. Stainless into stainless galls horribly.
Sir am felix jr. Can you make a cooled storage diagram system procedure. I want to make a storage 20 footer van in my place thanks you are genius good blessed you sir.
We repair a lot of different types of reefer units and I’ve learned to salvage as many used parts as I can because sometimes you can’t get the new parts on time.
Wow what a great way to solve refrigeration problem
Thank you for watching
Wow next Level Thank you I need this
Galing nyo talaga Sir
Really helpful video
thank
you
nice job sir
thank you for sharing Sir Jake. God bless you!
Great idea 👍
Really, it's a great idea....
I am also working in hvac any job are there so inform
Good as usual!
Simple and clear.
my dad works at your company as an OS. I recently passed my REE licensure examination. I'm looking forward to work in your company as well and work with you 🙏🏼
I'm Angolan I like you very much
Thank you for teach me
Great video and thank you for the content. Interesting, it's interesting that you have valuable cargo but not critical spare items to keep the valuable cargo in good condition.
Wow! Getting the thing to work at any, learnt something. Thanks.
Nice vedio thanks for sharing...
this is good to know. Thanks Jake
Great demo Bro. keep going. Thank you
Keep inspiring and sharing your knowledge , your videos provide confidence to cadets
Wow ngayon ko lang nalaman na pwede pala i override yang expansion valve dati akong maintenance ng supermarket di ko din naranasan na mag override ng ganyan kasi kung me problema nakakatakbo naman ako agad sa mga shop bagay yan kung nasa remote area malaking tulong
I had similar issue with our ECR AC, now i know what to do 🤘 Kudos to u brother!
You sir are a GENIUS
Many thanks!! Useful information
Sana ol sir maparaan pag dating sa trabaho
good day sir..lagi aq nanunuod ng vlog m at marami p aq natutunan,,ty
Great video. I may use this in my job one day. My job is on land, but a TXV is a TXV on land or sea
Yes TXV is a TXV but depends on where you work .. his containers stay shut I assume so there isn’t much fluctuations in heat load so as long as he has a good superheat it’s ok but if you’re in a busy restaurant walk in there could be risk.. but in a pinch this is very good sometimes you get a late night call or SupplyHouse is hours away
God bless you 🙏
thanks for sharing your knowledge sir...🙏
Thank you for your continuous support
that is a very streesfull work..
Hi @leckyjake
Can you show me how to install the air supply sensor in a Daikin reefer container, the additional sensor wires are in the electrical box of the reefer container but I don't know how to wire it .
Thank you my friend I like so much
Galing pare!
I’m also a refer tech 32 yrs San Antonio Texas.
Sir your video ❤️❤️❤️❤️ I get alot of knowledge
Pretty super ways and thanks
This is high level video hahaha Thank you to share this knowledge
Very nice sir😊
Thank you so much ur knowledge share me friend
No way that screw was M4. Great video though!
He already said the drilling bit was M4, so has to be at least m5 and more looking like M6. Great video though
Isa kang henyo lecky💯👍
Do u stock spare Compressors onboard?
Some reefers are located too much height, are u monitoring those
thanks
thanx sir so useful
Thank you Sir. 🙏
Thank you soo much ....😊
how about a stuck open expansion valve?
Sir how to identify that your txv is defective? Tank you sir...
Hi my friend Leckyjake, I'm speaking from Brazil, I'm trying to find out about the Alj281 from the Daikin container.. Other than the SMV valve, the SMV coil, and the solenoid coils, what else can cause this alarm?
Very good info.
But why u walk every day.? Pls use iot . Put sensors and connect with cloud and get full 24x7 data on your mobile phone.
You are super great
Secondly and firzt viewed po sir...👏🕊👍
Informazyuniz tiknikz po, txv subject nyu rin po pla anuh...
Thank you
hi may i know wht kind of refrigerant inside the thermostatic expansion valve...
Big fan sir
Does it possible to adjust this
have a breakdown p6-5 you can m explain
Can Make a Video on FCM
Can you so me what is the temperature of that cantenor.Sir
Can you find an empty refer and check to see if it’s the right one and rob it from the empty container?
They usually put the empty containers on the top so it’s a bit problem to extract the txv from 5 or 6 hight
Leck yung Eng.Room reefer po namin is ng frost po ang compressor at evaporator and expansion valves after 30mins running..ni research ko po posible na cause either flooded with refrigerant at defective na TXV po..may suggestions po ba kayo kung ano pa po mga reasons ng pag frost?
hello sir, may I ask if you have reefer bonus onboard?
How deep did you put that bolt to press the diaphragm? 🤔
Depends om the amount of opening needed for your setpoint
@@leckyjake you mean superheat
Its a little dangerous as the flow through TVX may become uncontrolled and damage the compressor(s)!
As he stated it’s for emergency repair only. And you have to remember this is a cargo ship and those containers stay shut during shipping so I don’t think there would be changes in heat load. As long as there’s is good amount of SH back to compressor is fine.
Also I’m sure it’s better to try this and save $300,000+ worth of product than $5000-$12,000 compressor
Oooh think mcfly
I'm from the EPA and I saw what you did!
May be deminimus?. Lol
it's only temporary unless it works
Why cant you use a piston instead?
Good day Sir. I just want to ask something. I have an upright freezer that I wanted to make the freezing faster. Can I use the TXV, to modify the speed of running refregerant. Thanks in advance for any info.
nope. txv is always the last thing that you need to touch on your refrigeration system. you may add cooling to your condenser.
👍👍👍👍👍👍
What about annex 6
What a very cool idea! Did the company put you through a refrigeration school as well?
Thank you very much.
+John Cantrell Refrigeration basic and troubleshooting was already there in his major I guess.
@@Neo-po2xw Carrier does reefer classes for certification. It will cost you couple hundred bucks though
