Case-IH DX33 PTO not staying in gear.

[grpuetz]

Good day all!
Has anyone on here had a DX33 PTO not wanting to stay engaged? Drops out immediately. Runs fine without mower attached. Had this issue a couple years and finally its bad enough the father in law cant keep it in with a bungy cord anymore....ya Would it be a linkage adjustment issue or will i be diving deeper? Thank you.

Welcome to TBN!

Could be the rollpun through the bellcrank is worn, not allowing the PTO to engage fully.
Also could be the detent spring/ball is worn or broken.

The hand lever turns a small shift lever shaft that goes through the transmission case. It is common that the shift lever shaft going through the case has been rusting for some time limiting how far it moves. Then, being that the gears are not fully engaged, they want to pop out hence the need for the bungy cord. You can spray penetrating spray where those shift shafts enter the case and work them back and forth. You need that gear to fully engage.

If that simple fix doesn't work, then there are many parts inside that could be the cause like shift forks, roll pins, shift lever, gears, etc.

Yes, it could be any/all of the above. Experience tells me if the shift lever "feels" right, and one can feel the detents for both neutral and "engaged" then it's not roll pin or shift linkage related. Much more likely it's some chewed up gears on the inside. I've seen and repaired far more of that problem than any roll pins or shift forks.

It's not all that difficult to repair once the lift housing has been removed. The shafts involved will come out the back, and the gears will come out through the top. It was much easier on the older tractors when tinware was tinware. You could remove the seat and the lift housing was right there looking at you. Then they "improved" thing adding all the plastic fenders, panels, and all that. Not so simple any more.

Thank you all for your comments.

I will remove the seat tonight after work and look for the lift housing plus look to see if everything is free and clear on the linkage.

I will reply soon.

TC34DA Rear PTO keeps disengaging

My TC34DA has 900 hrs on it. This year noticed the rear PTO disengages. RPM stays steady and the PTO handle kicks out of detent and moves forward about an inch. Reengages just fine amd does it again about 20 minutes later while mowing with landpride 72 inch finish mower. Anyone ever...

My pto lever dosnt want to stay forward when under load. With nothing attached to the tractor it works as it should. I removed seat and fender and looks like the lever works as it should there too

I think you're missing the point. Your problem Isn't with the shift linkage. It's in here.

Thank you. I do agree that it seems inside the transmission.

I am looking to converse on how to fix it. Should i assume that i need to remove both fenders and work toward draining the oil from the transmission and get the top cover off? or is the problem area accessible somehow else?

 

[Halftrack]

Please confirm by disconnecting the linkage and checking that both detents are being met before digging into the tranny.

Unfortunately yes, the fenders will need to come off to allow removal the lift housing. When I get into one for this reason I also remove item #3 on this diagram. It provides another access to reach in and wipe out more of the scrap metal fragments.

Thank you.

I will get the other fender off and see where that takes me. Thank you for now. I'll be back with more pictures and questions.

 

[grpuetz]

Yes the feel like they are operating as they should. I’ll take off other fender and foot platform if necessary next. I do see the lift housing casting on top of transmission. Also I’ll drain the oil too and resave it as it only has 67 hours of use to it

Well we found the problem.

Pto gears are torn up

Took off seat and both fenders then took off the top of rear end where the 3 points attached. The 2 meshing gears need replacing. Now need to find some part numbers and a place to get them

Is your tractor a hydro or gear?

 

[dieselscout80]

Can those gears be replaced without splitting the tractor?

 

[ruffdog]

Does this look familiar?

Viewing a thread - Dx33 pto not staying engaged

Notice the parts list pdf file. Strange, the parts are identical to my NH TC33D parts book but some numbers have been changed.

Someone has being forcing that PTO lever and grinding gears, instead of using the clutch to engage the PTO. Over time, it leads to this situation.

Messicks seems to be a good source for parts.

123 range hydro

Yes I believe so. There just inside the external pro shaft
