190XT torque tube issues

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Last spring I had my 190xt on a small harrow in the hay field and it started making a thumping noise I unhooked and proceeded to drive it to the edge of the field when the tractor suddenly stopped moving. I shut the tractor off and did a walk around and checked all the fluids and they were full. I pushed the foot clutch in and started the tractor and the tractor runs flawless no vibration until I let the clutch out then it thumps and shakes like a sob doesn't matter what gear or what pd position. Push the clutch in and all vibration and noise stops. The vibration is coming from behind the foot clutch and ahead of the transmission. Once towed to the yard I removed the hydraulic sump and found what appeared to be gear pieces. My question is what in the torque tube is possible to fail and where are the gear teeth likely from? Thanks

	Probably from the intermediate gear/PTO gear area. Drain the hyd oil and drop the oil sump where the suction tube/return filter connects and you'll probably find your issue.

	The very top gear on the clutch shaft is splined to the clutch shaft and held in place with a variable width snap ring and thrust washer. The splines between the gear and shaft like to wear out over time. You can barely see that gear when the sump is removed, but that may be your problem.

	Any damage to the intermediate gears is going to require a split at the rear end. Roll the rear end away and then you have access to the gears. You will likely have to remove every gear and shaft out of the torque tube. I have replaced a few main clutch shafts from the rear on those tractors. It's kind of a big job.
