190 xt surging/sliping

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

   Hi I am having some sliping problems with my Allis, I pulled the tractor out of the barn for the first time since August of last year. I took it for a ride around the field to warm it up so I could change the oil and filters. When I was driving it in 3rd gear, it topped in its tracts, and then about 30 seconds  went by and it took off again. It did this on several occasions. When I put it in 7/8 gear it did not want to move, but eventually did when I increased the throttle. Also when it was moving in 3rd gear, it didnt seem to be moving as fast as it did the last time I used it. If any one has expierinced this before, and has any info onthis problem, I would greatly appreciate it. I did check the hydraulic oil uder the floor board, and it at its correct level.
Thanks Adriano Stockbridge MI

	Check your suction line from the sump to the hydraulic pump for an leaks/cracks. If it's sucking air anywhere you could be intermittently losing prime at the pump. Mike

	Sounds like a Power Director issue , does the steering and 3 pt work ok? The POWERDIRECTOR clutches are held together by hyd. oil pressure , if that pressure isnt enough they slip, DONT LET IT SLIP LONG ; the clutch plates will break , warp , and then its rebuild time ; need to check ,like Skyhigh said ,the hyd. tube ,hoses, connections from the sump, theres a screen in the sump , may clean that ,change the hyd. filter, work the steering, 3 pt . ,with the tractor setting still ;PD in neutral ; make sure the likage coming from the PD lever is loose and moving without binding , a -fixit- manual will help you to check that the POWERDIRECTORS valve is letting the correct pressure of oil to the PD clutch ; HTH

	Doug's right, I'd bet on it. Power Director is slipping or not fully engaging.

	Charlie: How can you figured out if the Power Director is fully engaging? By push the shifter in or low? Edited by Dutchboy Johan - 25 May 2010 at 7:16am

	I'm afraid you'll have to reach out to others for that. My knowledge of the power director is in D series tractors only. I'm not sure how the 190xt is engaged. The D series tractors were mechanical, just throw the lever. Inside the power director is fairly simple. It's just two wet clutches back to back with a lever assembly that pushes them forward or rearward, engaging one and disengaging the other. Most of the time one of two things keep them from working. Either some shims need to be moved around between the clutch packs or there is wear in the mechanism that engages/disengages the clutches. With the later tractors with more or less push button actuator controls on the PD the problem could also be in the "push button" mechanism. I better stop because I've already gone off into areas where I'm repeating hearsay and not actual knowledge. Hopefully someone else will pick up where I left off and correct my errors.

	The power director valve is plumbed downstream of the pto valve, unless you have a manual pto (in this case I am not sure of the plumbing routing as I have never worked on one of the manual pto tractors). There are two ports (1/8 pipe thread) on the power director valve. One is for testing high pressure and one for low. Run tractor at pto speed and check the pressure at each port with a gage. I think pressure should Be 190 psi, need to check the manual for sure though. Move the lever in and out of high/low a few times as you do it. My guess would be your linkage may have seized sitting for so long but you could have a problem in the valve to. I have fixed a 200 that ran with both clutches screwed and you don't want the parts repair bill for that. Best to fix them as soon as they start to slip.
