Looking at a 04 wa200 loader. Oil report shows 99 iron and 31 silicon. How bad is this?
well your silicon is almost x4, maybe they have a bad air filter letting dirt in, scuffing the pistons and rings grinding against the cylinder walls.
Can't see for sure what compartment this test was for, maybe the second column is for the transmission??? First column the engine??? As discussed in another thread today oil sample report of just one test does not tell much. How many hours on the oil, on the machine, what was it showing 100, 200, 500 hours ago?? Here is a section out of a report for a Komatsu WA600 transmission a 1996 machine with 25,000 hours on it. Forgot to mention the dates for these samples started in 2010 at the top of chart and 2016 for the last sample. Last I knew as of April 2015 it had not been opened up since it left the factory, other than fixing some external leaks and replacing some hoses.
Anything with silicon above 10 has got major issues with dirt entry. We work in a dust bowl here and most if not all of our engines are around the 5-8ppm mark for silicon, transmissions are broadly similar and often less. Oil analysis specifications are generally silicon below 9 with hours on oil at the recommended change period (250, 500, whatever depending on which compartment it is). A transmission with 31ppm of silicon in it hasn't got long to live unless it's fixed PDQ.....the 99 iron is a direct result of the 31 silicon IMHO.
Engine is on left, Trans on right.
Looks like engine oil was changed 222hrs ago. Not sure on Trans.
Can you pull the transmission filter and rinse it with solvent to check for visible metal flakes?
Do you have any previous oil samples ? Is fill cap missing or new for transmission I'd drain trans inspect really well. Then sample after one shift. How was sample taken could this be from bottom of sump was machine up to temp before sample was taken ?
Those sample reports are typical for high hours between changes. The lead and aluminum in the engine indicates bearing wear. Not sure about the silver and nickel. The high readings on the transmission is typical of gear or seal ring wear on old oil. I believe a WA200 has a countershaft transmission that uses steel hook ring seals on the ends of the gear shafts and clutch packs for sealing the packs. When the tranny starts getting loose you see that kind of iron reading and aluminum reading. That's usually not enough aluminum to indicate the torque converter is going bad. Were it my machine I'd do stall checks on the drive train and check main and pack pressures for any signs of slippage. The drop dead symptom of a bad hook ring is the transmission slipping in one or more ranges. At least the good thing is the auction company shared the results. A lot of curb stoners would have changed the oil before taking a sample.
I just sent out two oil samples myself, hyd fluid after a change and a trans fluid before change
