I have a Bobcat T190 and have recently been having issues with the right track. The machine is about a 2004 (not positive but I can verify the year if needed) with foot controls and about 1,300 hours. Lately the right track does not seem to have as much power. Everything seems to work fine until it has a load applied to it. When going straight ahead and pushing, it will just not move with the lever pushed ahead. The first I noticed it was when I was loading it on a tilt-bed trailer and it was acting almost like it was slipping when I drove it on the trailer. The other day when I was moving bundles of wood, it would act up when I turned to the left using the right track. It would drive, then pause for a second, then drive, then pause and so on, kind of a in a jumpy motion.
All other functions are working fine. I have not used the auxiliary hydraulics recently to see how they are working. My dad was using it a few weeks ago with a brush mower and he didn't mention any problems. Is there any way that this could be related? Since we bought the machine new, it has always had a slight whine at full throttle that sounds like it may be from the hydraulic pump. My dad thinks this has gotten a little louder, but I haven't noticed any issues. Not sure if this could be related.
The hydraulic fluid, hydraulic filter, case drain filters, and oil in the final drives was changed about 300 hours ago. After researching the issue a little, I read about a charge pressure filter, which I have never seen. I've looked around the machine a fair amount, but I haven't seen anything. Can anyone let me know where this is located? Could this be the culprit?
So far I have checked the following:
-There are no error codes or warning lights.
-I checked the case drain filter for the right track and it was still a bright brass color. If I looked very closely, there were some extremely tiny particles on the filter, but I highly doubt it is any indication of a failed drive.
-While I had the case drain filter apart, I checked how much fluid was coming out of the case drain on the right track while the engine was running and it was a very small stream.
-I removed the sensor under the hydraulic filter on the back of the machine and hooked up a pressure gauge. The pressure was between 250-275 psi with the engine at mid-throttle.
-Should I check this pressure with a load on the hydraulic system? Is there any easy approach to do this?
-I removed the hydraulic filter on the back of the machine and there doesn't seem to be any indication of debris in the filter.
Thank you in advance,
