![]() ![]() ![]() I checked all scv outlets and get a pressure reading of 2800 when used. When i used the loader the tractor wants to stall out, steering and brakes both work fine, but definitely changes the sound of the pump when used. I had a leaky hose that ran from the pump to the priority valve and another one from the reservoir on top of the pump, both hoses were replaced. Checked the priority valve spool and it's moving freely, also checked the compensation valve. Checked that and found it was broken completely, replace it and still have the issue. I reviewed several posts online, it appears a check valve on the braking system typically has an o-ring failure. The pump whines as soon as it's started, still have a shudder when moving. Still having issues with overheating after about 45 mins of use, which isn't going to work for us. Once the reverser controller doesn't see speed it defaults back to neutral and flashes the warning lamp to indicate that it. What the tractor will do is start to move then realize that it doesn't see speed from the sensor. may not even be related, but thought I'd throw in in there too.ĭecided to revisit this issue, as we now need to use the tractor for hay. The issue that you are experiencing is most often caused by the transmission counter shaft speed sensor. I only noticed this because an area where there was no green paint caught my eye. One other note.the hose that is clamped off the bottom of the reservoir in the rear behind the SCV's appears to have moved a bit, maybe 1/2"? As if the pressure was increased to the point where it was being pushed off the nipple. I replaced the temp sensor already, thinking it may be a culprit and both boom cylinders are currently getting rebuilt because I did have some seal leaking issues, they always leaked just a tiny bit, but I think the hotter fluid caused them to fail all together (just the seals on the shaft end, the piston end worked fine to raise and lower). Did I miss a step during reassembly where I should've bled or primed the system somehow? Everything works as it should, steering, breaking, loader and all gears and ranges of the transmission however, I do feel a little shutter when I'm in a higher range gear. I topped off the system to make sure I was good, and everything repeated.30mins of use, light comes on.shut down. After about 30 mins of loader use my hydraulic temp light comes on, and I'm not sure if its psychological or not, but it seems like the pump in the rear is making a bit more noise than usual from the start I shut the machine down to let things cool (the filter on the right rear side does feel hotter than normal), I check the fluid and find small bubbles in it. I think the prior owner had a joint fail, and when the shaft was spinning wildly perhaps it chipped the shaft end? Everything came apart and went together easily as it should, I refilled the system, changed all filters and fired it up. I noticed the shaft was cracked (on the outside, no damage inside) while changing out the u-joints on the short driveshaft from the engine. I recently had to change the pump located inside the front of the transmission. I'm having an issue with my 6410 that perhaps someone could help with?
