As I recall, the unit in the video came from digikey.com.

Thank You

The best explanation that I've heard is that they are being overloaded. More weight means more power going through the relay which over loads it and burns it out.

@ so nothing down or up stream is shorting out just over used not enough cooldown time

@@ggrandma-n6e I don't really know of anything else causing it. The machine in the video was being used with heavy rugs and blankets.

@@repairsecrets makes sense thank you fingers crossed we’ll be getting mine this weekend thank you for your reply’s cheers

Finally got some time to get back to making videos again.

You will have to be more specific. I don't remember that alarm. What is the machine doing different than normal?

If you are speaking of the screws that are directly opposite each other, those adjust the short side of the reaction lever for the servo valves. Usually they are only adjusted when the pump is being assembled and should not be touched with the pump in the machine. They essentially change how the pump controls react.

@repairsecrets thanks for your reply

I wish I could help you but I don't have access to one. There used to be a guy in Russia who would sell PDF copies of manuals but I haven't been on that site in a couple of years. Best I can tell you is that Google might be your best bet. Good Luck!

Try Digikey. www.digikey.com. They carry just about everything electronic.

The owner of the machine told me his wife and mother in law were loading rugs and blankets into the machine all the time. Since making the video I've also found out the machine was likely packed with lint inside around the drum and motor. I'm thinking the machine needs to be taken apart once in awhile and cleaned out good.

Вы используете переключатели режимов на левой стороне панели. Вы используете кнопки A или E для переключения режимов. Машина должна иметь соответствующие трубопроводы и компоненты, чтобы использовать прерыватель. Обычно она не поставляется с завода с уже установленными трубопроводами и компонентами. Выходы насоса также должны быть установлены перед использованием прерывателя.

I'm not sure I understand your question. First thing is I've never worked on a PC2100. That's a little big for the area of the world that I live in. Are you saying that your machine doesn't have any electrical signal or power on the travel solenoid and the hydraulic lock out?

Are you talking about the dial indicator?

What is the smallest gage wire you would recommend? This is a power relay

@paulrite5358 18, 20 or 22 gauge Should also work fine. The amps rating gets pretty small at that size. And I'm not sure how it correlates to a circuit board.But you're going to need some wire mass that sodder can connect to. Good luck.

As I recall I had to use a small cutter wheel on a Dremel tool to cut the bottom of the cover. The points in this thing were melted together. There wasn't any way to save the component and for twelve dollars it was worth the effort to try.

@@repairsecrets oh ok. I just fixed my washing machine's drain pump. It wasn't turning on. I used a razor blade to slice off the top of the relay. Inside there is a solenoid that pushes two copper plates into contact. That's how the pump turns on. There was carbon or some other buildup. I simply cleaned off the area where they would make contact and glued the lid back on.

@@smkie-hf9pz That's good work and thanks for the heads up on what can be done.

I replaced the relay and reinforced the solder trace on the board with a short piece of copper wire and solder.

This was just a project where the client had nothing to lose so the possibility of repair was worth the risk of a failure.

Thank you for the comment. It is appreciated.

Can you give me the time stamp of where you see it at?

That would be a considerable amount of play. One eighth inch would be 0 .125 inch in decimal measure and a 307E2 Caterpillar is a small excavator. There was a problem in the small Cat excavators around that time where the inside mounting bolts for the bearing were breaking. You might check with your Cat Dealer to see if it might be affecting your machine.

@@repairsecrets@repairsecrets Thanks, I'll check it out. yeah, cat quoted 16 grand to replace it.

I don't have anything on those earlier dozers. They weren't very complicated though. There were no processors in them, only starting, charging, sensors and lights.

Thanks for the question. I don't have a video showing testing those components. They are easily checked using an ohm meter. Most are three wire variable resistors. Unhook them at the harness connectors and then check each wire to the body of the component. There should be no continuity. Next check each wire to the other wires. There should be some resistance that can change when the linkage for the component is moved. As I recall the center wire in the connector is a power wire from the computer and the other two are the sensor wires. There was a lot of problems with those machines and Komatsu did not make any information available in this country.

Unfortunately, I have never found anyway that could be done other than purchasing a new monitor panel. If you find out how, let me know and I'll do a video on it. Thanks for the comment.

I'm happy to hear of your good work. It's amazing how far this reaches. Thanks for posting the comment.

That is the indicator for how much soot your DPT has in it.

You can only delete mechanical codes. While in the code menu, push the up arrow and then 1 and 2 and then 3. When you let go the next screen that comes up will ask you if you want to erase just the one code or all of them. Good Luck!

@@repairsecrets thank you sir ,more bless to come

My experience is on older machines but a black screen usually meant a power problem to the screen. The bad screens usually turned kind of a purple color when they went bad. I would just try the buttons to see if they work. Check all the fuses first.

I'm sorry I don't have either. Thanks for asking the question.

Thank you for the comment.

@@repairsecrets ı need maintenance information for pc300-5. İ need also some oring seat kit.

That is a very good question and I don't know. That's part of the reason I put that copper jumper wire in. I think the load is variable depending on how heavy the material that is being dried is. The owner of the dryer said his wife was washing heavy throw rugs and then putting them in the dryer and he thinks that was the cause.

I have a book now, looking for a machine.

I has been my experience that monitors that have turned a dark magenta color are not salvageable. I has also been my experience that the monitor panels are specific to models by part numbers. There are some after market units made in China that may or may not work. In my experience that part number on the back of your panel is the best way to get one that works.

@@repairsecrets much obliged, i appreciate your advice. My local dealer quoted around 3k for a reman... I will look into the associated pn# and if the China land doesn't offer one we will take my grandfather's advice; ; "check the oil, the fuel will check itself". 😆
