d200 :) 1 #1 Posted April 28, 2020 Hi. Im new to transmissions. I bougth a wh d200, got it to run and everything worked. Then i noticed a leak from hydro engine at the back. I replaced the seal and emptyied the oil in it. Put it back together and now nothing works. Do i have to purge it or is it somthing else that could be wrong. Sorry for my bad english. 1 Share this post Link to post Share on other sites
pfrederi 18,000 #2 Posted April 28, 2020 Welcome Where is skein?? What seal did you replace. There are no seals on the hydro motor part. This is the manual for the hydro. Look at the parts diagrams, can you tell us where the leak was. Share this post Link to post Share on other sites

pfrederi 18,000 #5 Posted April 28, 2020 At the blue arrow? That we would call a gasket. Share this post Link to post Share on other sites

pfrederi 18,000 #7 Posted April 28, 2020 Just making sure I understand what you have. Do the two hoses in the picture run to box like this mounted on the frame?? Share this post Link to post Share on other sites
pfrederi 18,000 #9 Posted April 28, 2020 You have a dampener that was only used a couple years I am not familiar with them. Does the lift operate??? Share this post Link to post Share on other sites
pfrederi 18,000 #10 Posted April 28, 2020 Look at page 45. any steps you may have missed ? Did the cover come off easily or did it require effort. The retaining spring clip may have broken... Share this post Link to post Share on other sites
d200 :) 1 #11 Posted April 28, 2020 Ok no they do not work now but worked befor. Share this post Link to post Share on other sites

d200 :) 1 #13 Posted April 28, 2020 It did come of quite easy. retaining spring clip is that what hold the bearing in place Share this post Link to post Share on other sites
pfrederi 18,000 #15 Posted April 28, 2020 (edited) This is second failure reported here this week. I have to think on this some.The other was after just a fluid change. Spring clip I menat was in Fig 84 Edited April 28, 2020 by pfrederi Share this post Link to post Share on other sites

Cavitation, vapor lock or whatever it's called, could the pump be a little weaker from long use and now it can't pull up the fluid on it's own after being completely drained? Is there a way to prime it, like using air pressure in the dipstick tube maybe? Just kind of thinking out loud here since I'm unfamiliar with that transmission Share this post Link to post Share on other sites
daveoman1966 3,762 #18 Posted April 28, 2020 (edited) This is the SPRING CLIP that pfrederi refers to. It MAY have broken which is not all the uncommon. I ahve a new one if wanted. It is very likely that when you replaced the cover, you got it on upside-down. The HYD MOTOR COVER has a 'web' on one side and that 'web' MUST be on top... look at last pic.

pfrederi 18,000 #19 Posted April 29, 2020 Not coming up with any concrete answer...sorry. Can you push the tractor around with the tow valve closed? I have never had a problem with mine not repriming itself even after a complete tear down but i do not have the dampener valve. It may make self priming harder..(just a guess) You might open this port on the top of the pump and see if there is fluid.... This is also where you would run the pressure test shown in the manual..

d200 :) 1 #20 Posted April 29, 2020 (edited) Yes i can push the tractor with the tow vale closed. I opened the port and its ful of oil. Rhank you for cheking whats wrong since i can push the tractor with valve closed ? Edited April 29, 2020 by d200 :) Share this post Link to post Share on other sites

Thank you for the info. webing is upp. But could i damage the retaining clip just by oppening the cover ? I dident empy the hole system just the hydro pump. Was wondering if the release valve could be the problem could i try witout it. Edited April 29, 2020 by d200 :) Share this post Link to post Share on other sites
pfrederi 18,000 #22 Posted April 29, 2020 The tow valve when open allows the hydro fluid to bypass. Closing it forces the hydro fluid through the system. if it doesn't close tightly it could be your problem. I would start her up then open the valve at least a full turn it may flush out something that is keeping it from sealing. Then close it and see if function returns.

d200 :) 1 #23 Posted April 29, 2020 (edited) Ok i tried yesterday open it and started. then closed it did not help Edited April 29, 2020 by d200 :) Share this post Link to post Share on other sites
pfrederi 18,000 #24 Posted April 29, 2020 (edited) what kind brand and number filter is on it. also make sure the coupling between the engine and pump is OK and that the splined input shaft is not slipping. Did you use any sealant on the gasket? The diagnostic chart would have yu look in the transaxle but I don't think that is your problem, something wrong in there the lift would still function. i am afraid a pressure test as shown in the manual is the next step.

d200 :) 1 #25 Posted April 29, 2020 Ok copling engine and pump is ok. I used thin layer of paste behind the gasket dont remeber the number on oil filter but bougth it from toro. I wil try pressure test thank you for info Share this post Link to post Share on other sites
