Hello guys. I have a 1999 Samsung MX225 I bought from United Rental in 2005 in Houston , Tx. supposedly, United Rental bought several of these units off the Houston port from china. It is a grey market machine. Romco Inc. is the dealer I buy parts from. They say most parts are interchangeable with a Volvo EC210B and other Samsung machines made for sale in America. The machine is great shape, and has never given me any trouble other normal things over the years.
NOW TO BAD PART
I was using it one day , shut it down because I broke a cylinder hose on the boom. Came back a few days later to repair the hose . When I cranked up the machine, Nothing worked but the engine. No turntable, no track motors, no boom..............NOTHING. The day I broke the hose it spewed hydraulic fluid everywhere. When I came back a few days later and cranked the machine, I noticed there is not much IF ANY pressure where the leak was the day I broke it. In other words, seems the pump is not pumping.
SIDE NOTE :Now the machine has been sitting for a year and half and I see a lot of water mixture in the hydraulic system. I do not believe it is from condensation.
I called my friend at the dealership and he said
1. check the safety switch at the drivers seat to be sure it is working. ( I think I did it correctly and it seems to be functioning correctly).
2. He said it could be a pilot valve. (well, I'm not real sure what a pilot valve is or where its located) secondly, it looks like there are a zillion valves on that machine !
Any ideas where to start to diagnose the problem ?
Thanks for any help you may be able to provide.
