Hello everyone, I just bought two Cat 613Bs for building a road into a property I bought. The one machine is running like a top but I’m having issues with the other one.
When I’m dumping, the machine is really bogging down in the spilled topsoil to the point where it’s acting like it’s low on transmission fluid but the engine is making power. It seems to be ok while picking up loads (for about 30 min) at that point the engine bogs down to the point where it seems like the engine is over heating or something but the temps are good and there is lots of water and oil.
To start off, the previous owner replaced the shifter cable with something too long and it has too much play in it which makes it hard to get it into neutral. I thought at first maybe it was selecting a higher gear inadvertently so I spent a couple hours adjusting the cable to the point where that’s not the issue. I still need to replace the shifter cable with the correct one but it’s working for now.
When I check the transmission fluid after running a couple loads while the engine is running, it’s right at the full line. I’m not sure what oil viscosity is in there.
I’m able to get the loads out slowly but after running for about 20-30 min like I said above, all the sudden the engine bogs down to the point where it has no power and is losing RPM. This has happened twice and I’ve shut the machine down immediately when it’s happened and at this point I’m a little scared to do anything else until I’ve tracked down the cause. On shut down the temps are at 210. On the oil pressure gauge seems to be reading low. The previous owner said it’s always read low at 15 psi but on the other hand I’m scared I can’t trust it. It does drop way below zero when it’s shut down so I think maybe it’s just out of calibration. I think I will pull it and test it with an air compressor though and potentially replace it for piece of mind.
As a side note, I drove the machine 2 hours down backroads when I bought it not using the hydraulics except to turn and there were no issues.
I think my next steps are to pull the transmission filters and replace the fluid and see if that helps. I know sometimes water can swell the paper filters. Does anyone have any insight or things I should also check? Any help would be appreciated as in shooting blind and haven’t really owned anything like this before.
As a couple of extras things that might not be related but you never know: This machine belches black smoke under load. I think it’s very rich and maybe there is a fuel screw adjustment? It seems to have more power than the other machine that is running well so I think maybe it’s turned up a bit?
Also this machine turns left very slowly. I’m guessing the ram probably has a bad internal seal?
Thanks in advance to anyone who can provide some tips of where to start looking?
