Hello, im new to this forum. I have a problem with my 2007 cat 301.8, On the display panel i have blinking 5 number after i start the machine. And it doesnt go off. mini ex runs well, those 2 buttons on the panel they dont work. I dont know if i have to replace panel or what. any help would be great. Thanks
Welcome Matt. 2 questions - What's the Serial Number and do you have an Operation Manual for it.?
I bought online manual, but there was nothing about that. And why you need s/n ?
In the Caterpillar world, all research starts with a serial number. In this case, there are 3 possibilities, and the 3rd is absolutely different internally than the others. And, it's quite possible that the 1st 2 vary quite a bit, too.
Looking further, it would have to be a 301.8C, with a JSB prefix.
Ok Cat3018cajsb02558 there are no lights on the display. But they are all working when i turn the key before start. And wrench is blinking Thanks for help.
That would've all been good info to put in your OP. When was the last time it was serviced, just out of curiosity.? Try resetting the Service Indicator first and see where that gets you. If you have a manual the info in HMC's last post should be in it. Did you miss that.?
One of our customers has one of these and I've done some work on it. The technical info in SIS is pretty scant and in my considered opinion it's made by another manufacturer with Cat livery stuck on it. There are some telltale signs such as automotive style captive nuts and DIN spec metric fasteners which I've never seen on any other Cat offering. Does anyone recognise a similar display from another breed of machine?
Actually, this fits your symptoms, although if your serial number is correct you should already have the latest and greatest instrument panel fitted from the factory.
Yes when i got this mini ex i changed all oils, and filters, and glowplugs. Those little buttons on the display they dont work, thats why i couldnt reset it. So it looks like i have to change the whole panel?? But the hours will start from 0 again?
I'd suggest that you follow the instructions on the Service Magazine posted above by Cmark and check the electrical connections on the back of the panel as a first step. A long shot, I know, but if that doesn't fix it then it appears that you're in for a new panel. Price looks to be somewhere around the US$250 mark.
Cables are good, checked that. Panel in canada cost 500$, so maybe i will buy it next time im in us. thanks for your help
