Would 1/8 of an inch be too much play on a 307e2 cat?
@repairsecrets16 күн бұрын
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.

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.

Fault code 14 is disconnection in swing brake solenoid system. You can get this fault if the swing brake prolix switch is in the full time release position. Fault code 23 is front pump pressure sensor sensor system. It can be a bad sensor or a problem with the wiring. Fault code 26 is the engine speed sensor problem. You can check the sensor with an ohm meter. It should show around 3 to 8 ohms resistance between the wire leaks and no continuity between a lead and the body of the sensor. Good Luck on the repairs.

If it is a mechanical relay like the one in the video, you will usually feel it click when you energize the coil. You can check the coil resistance with an ohm meter. In general they will be around three to five ohms. Depending on the number of working contacts in the relay there will be two or three circuit paths for the relay to switch too. There will be a common contact which will be normally closed to one leg when the coil is not energized. The other contact will be closed only when the coil is energized. I've never checked for differences in voltage across a relay. The ohm meter tells a better story.

@@JoshuaRichards2010 Engineering design doesn't work that way anymore. The engineer has a couple of dozen catalogs in the book case behind him.

I wish I could help you with that info but it was never published that I know of and the local dealer who built a pump dyno didn't even tell us in the field about that stuff. We did use the travel functions or cycle times on boom up to see if it was working properly.
Damn Samsung potted their board so I can't even look at the back of the PCB without really being careful with a Dremel and razer blade.
What do you mean be potted?
@@repairsecrets My understanding is that potting is a form of resin that boards are dipped/sealed in to protect them from moisture/environmental exposure.
You know in vehicles these relays are swappable. If they made the board the same way this would be easy as pie. Guess we all know why they don't...
The relay apparently was a standard part. It is a lot smaller, runs at 120 volts AC and is soldered in place on a circuit board. I don't understand your point?
@@repairsecrets A relay is a moving part. Moving parts tend to break and need replacement. If they designed a socket for the relays to fit into, like they do for relays in automobile fuse boxes, then it would be a cinch to swap out a failed relay instead of having to solder it.
@@JoshuaRichards2010 Engineering design doesn't work that way anymore. The engineer has a couple of dozen catalogs in the book case behind him. He needs a component to do something and he doesn't have the manufacturing capability to make it so he picks up a catalog and looks for one supplied by someone else. It has to meet specifications and apparently for this use, this is what he finds. Automotive units aren't this small and solder is the accepted method of attaching to a circuit board. The big deal is that people shouldn't put huge loads like heavy coats and floor rugs in the dryer to pull so much current that it burns out the relay.
@@repairsecrets My dryer is 30 years old. It takes big loads like a champ. They don't build them like they used to.
@@pibblesnbits I can beat that. My WP dryer is 35 years old & still going strong. They didn't have circuit boards...control was all mechanical.
How do you reset it mine has ecm error stuck on it
If you can't clear the code, it means the reason for the code has not been repaired yet.
hello how are you my friend what does error code E03 mean
I am well and I hope you are also. The E03 is an operator code that informs the operator there is something wrong. You should check for fault codes in the diagnostics. Is the machine not operating correctly.
In box me via Gmail
I don't understand what you are asking?
What gauge wire you used?
As I recall I cut one strand out of a piece of 14 gauge stranded wire and then laid the solder over the top of that.
This is a good and useful topic - mister John! If you find more time and motivation, please share more of your knowledge and experience with heavy equipment wiring.
Was that relay still clicking? How did you know it was that particular relay? I'm trying to troubleshoot my Thermoking apu motherboard.
I didn't do the troubleshooting on the relay. My friend looked up common problems with his machine on the net and came up with this. The new relay did click when he reinstalled the board.
@@repairsecrets How are they held on? What did you use to pull it off? So the burned out relay didn't click anymore?
@@supertrucker1356 They are soldered onto the board. I have this tool called a solder sucker. You heat up the solder with and soldering pencil and then suck up the solder with the suction tool. Look up solder sucker on the web.
Very helpful
if I only have the ecm summary of diagnostics, how do I get the rest of the menu?
I don't understand your question. I don't remember there being a "summary of diagnostics." Going into the service menu is where all that information is at. If you can't get into the service menu as described in the video, you may have a problem.
kenmore electric dryer he5t -error F01 code bought a new relay switch and cleaned up the board and re-soldered the new relay switch and put all back together, but it did not work? Just wondering not the best a soldering could this be the problem
It's hard to say without looking at the soldering job. It also might have had something else wrong in the dryer.
F01 is the thermistor error.
Do you have many job opportunities in the area of heavy maintenance in your region? I'm Brazilian and always wanted to work abroad. here the pay is low
Plenty of openings here for good mechanics. Pay is pretty good as well.
I already got a pc 200-8 that this connector wouldn't let pass 5 volts to the pressure sensors.
