Bob, The PTO clutch on the 2840 is a wet hydraulic engaged unit located on the PTO shaft drive line in the transmission, between the clutch housing and the transmission split. To service the PTO clutch you will have to split the tractor between the clutch housing and the transmission at the back edge of the two lever shift cover. To do so remove battery boxes and covers, floor plate around shift levers, disconnect light wiring from switch, disconnect neutral start switch harness from switch, drain transmission/ hydraulic oil, remove shift cover with levers, remove short spring on reverse shift rail under the cover, remove two 1/2" bolts and washers under shift cover, disconnect high pressure hydraulic line supplying back of tractor (right hand side), disconnect brake lines from brake valve, remove hydraulic filter cover and remove hidden 1/2" bolt, support front half of tractor, use floor jack under back half, remove the remaining 1/2" bolts at this splitting point and roll tractor apart. the PTO clutch is the first thing that you will see. It mat stay with the front or rear half of the tractor when it is rolled apart, Be sure it is in the back half when assembling and that the two metal piston sealing rings are all the way inside the manifold so they are not damaged when rolling the tractor back together. The clutch unit can be removed and disassembled on the bench at this point one large snap ring will give you access to all the plates and disk. You may also want to look at the PTO brake while you have the tractor split, it is locate in the front half of the tractor on the PTO drive shaft and is a disk type brake that has a lining on a brake pad that can wear out and fail. This is not that bad of a job if you have done a few before and I am sure there may be some small details I have left out but if you are handy you will get it done. If I was doing this job I would turn it out in about eight hours. If the tractor has a loader and frame in the way it will take a little longer to work around it. System pressure should be checked before and after the work is done to make sure there was or is not a leak in the system that caused problem. This is something that is not hard to do as the test port is in the top cover. If you do not have a test gauge have the dealer check it before you buy it to check for any leaks that could affect the system pressure and cause clutch to slip. Pressure will be checked with the high side of high/ low engaged as well as the low and PTO ON and OFF to check those circuits for leaks as well. Good Luck! Dave W.
