The hydraulic hose to the right drive motor blows and was replaced by Waukesha Pearce. They also replaced the HST filter and replaced 25 gals of hydraulic oil. Very limited function test.
I ran it briefly and stopped when I received a HST filter clogged alert. I stopped and removed the filter and it had a few small brass shavings and a small glint of silver metallic dust that would not stick to a magnet. Put it back on and it alert again and I limped to a more desirable location and parked it. Engine running perfectly and an easy starter.
Next morning returned and had forgotten to turn off the battery disconnect. I tried to start it and the batteries were low but it did start and run briefly but may have had a fuel starvation sound and died. Hasn't started since. Cranks but no start no smoke
Tech comes back out and it won’t start for him and he was not prepared to jump but did hook up his truck for 3-4 hours while he was there. He removed the filter/separator and said it was only half full of fuel. He blew the line back from the filter to the tank and initially had significant resistance. He then pressurized the tank and fuel flowed freely to the filter.
He returned today after I had drained and replaced all the fuel, changed all the fuel filters, bleed the system and replaced the batteries which the old batteries charged and tested fine. He spent all day today troubleshooting. Rail pressure is good. No codes whatsoever either in Komtrax or when he queried the ECM directly. Bleed the rail. Nothing. Won’t start. No smoke. The injectors are controlled by the ECM. Starting fluid does nothing. It does sound like it wants to start.
He wants to come back Monday, pull the hood and manually check the injectors which will take 2 days in certain. It costs me no less the $1000 every day he comes out. I’m thinking of replacing the ECU myself. It’s cheaper than having him come out for 2 days and I don’t think that all the injectors failed overnight! The ECU on the other hand might fail abruptly. It’s either that or something so simple it’s not obvious. I’m getting a bit desperate to find a solution.
Komatsu D61PXi-23. When I initially backed it off the trailer I was very pleased with my purchase until the line blew. I’m sorry for the essay but wanted to give you as much info as I can. If you have any advice please do share it! I’ll be forever indebted!
Thanks! Kevin
