4110 pto speed selector

[mboulais]

My PTO on my 4110 will not run in 540. it will run in the 1000rpm setting.
When I start the pto in 540, the selector lever jumps a couple times and drops out to neutral. Holding it engaged gives me the distinct impression that the gears have been damaged. I suspect someone stepped on the lever and forced it out of 540 while it was parked in the barn. Given that it runs smoothly in 1000rpm, I suspect that either i am dealing with two completely seperate pairs of gears or that the common gear is undamaged.

Has anyone had the tranny apart for anything?

Can I get into what I need to see by pulling the seat and body panels, then a top cover?

Removed the seat, the various levers and a little sheet metal. Getting close to finding out how bad it is.

I am having this same problem with my 4110. My pto will run for about a minute and then start to chatter like its only half engaged then just fall out of speed. Hope you are able to figure your tractor out. Keep us posted on what you find.

I was camera deficient tonight but pushed ahead anyway. I would suggest you wait and see if I pull this off before disassembling yours.

tonight I took all the bolts out of the transmission top section and peaked in... I quickly decided I need to remove the diesel tank to get enough clearnce to get it apart. The good news is everything is coming apart relatively easy and it seems to be built for maintenance.

If I did it again I would start by running the tractor almost out of diesel then begin dismantling.

Step 1: Remove rollbar (8 bolts with lock nuts) Cresent wrench and ratchet with I think a 7/8" socket are required. Note to self - Get help next time.

Step 2: Remove Seat (pull clip on pivot pin and slide out pin)

Step 3: Remove Seat slide from rubber mounts. Mine were double nutted and I needed two small metric wrenches, 12 or 13 mm.

Step 4: Remove hyd remote lever top half ( 1 bolt 12mm or 13mm head)

Step 5: Remove draft and 3-point levers top halfs (12mm or 13mm wrench, 1 bolt each)

Step 6: Remove shifting knob, by loosening lock nut underneath then turning off. Cresent wrench.

Step 7: Remove covers around shifter and 3-point levers, 2 bolts each and cliped into fenders. 13mm wrench.

Step 8: Remove sheet metal plate behind seat. A row of bolts across top and about 4 on bottom, also 13mm wrench.

Step 9: Remove floor plate, 2 or 3 bolts left on each side at this point and 4 or 5 on front. 13mm wrench. Guide the rubber sheet over the levers before lifting the floor plate all the way up. (Note for reassembly: the two really long ones are in the back corners )

Step 10: Remove back end of remote hyd linkage from valve ( leave attached to lever). 13mm wrench

Step 11: Remove linkage bars from 3-point depth and draft control levers by removing snap rings at each end, you'll probably loose most of those. I did. They are actually E-clips and I popped them off with a small flat screwdriver. catch the washers and slide off the bars.

Step 12: Remove the mounting bracket with the levers still attached ( I screwed up and took levers off first). 3 bolts , 13mm wrench

Step 13: Remove the cross brace above Diesel tank. the rubber grommet around the fill cap comes off easy with the cap off the tank. Tilt the bar forwar and disconect work light (1 wire, plug-n-play). Found a huge mouse nest under mine.

Step 14: Remove pins from top end of 3pt lift linkages

Step 15: Remove pins from top link mount and remove top half of top link mount.

 

[mboulais]

Step 16: Seperate linkage from draft sensing mechanism ( under remote hyd valve, right of top link) 13 mm wrench?

Step 17: Remove all bolts from upper section of transmission, roughly 15 of them, 14 mmm socket and combination wrench. ( Long ones at back around Rockshaft )

Step 18: disconnect diesel line from filter at front of tractor and drain remaining deisel into a fuel can.

(This is as far as I got so far... I pulled some other stuff off in hopes of sliding it out under the diesel tank, but that dream was crushed tonight. )

 

[windyacres77]

Thanks for the step by step. Hopefully things are moving along smoothly.

 

[mboulais]

@windyacres - No problem. This might help me put it back together too.

Step 19: remove hoses from diesel tank

Step 20: disconnect wiring on right hand side (facing forward)above tank . cut all cable ties to release wiring harnes from tank across top and down left side. Slip harness out of permanent sheet metal holder, low on left side.

Step 21: remove all fasteners from tank (2 near top on each side and 4 across bottom. The ones near top on sides have metal bushing and rubber washer under them. The rubber stays with tank ok, but the bushings need to be captured. 13mm socket and ratchet

Step 21: slide tank down and slightly forward until top corners clear brackets then lift out.

Step 22: remove 2x2 angle that supported bottom of tank. 13mm socket and ratchet

Rockshaft assembly looks good. Both the gear on the upper shaft and the one on the PTO shaft below it are shot. I found plenty of metal filings in the bottom. Looks like some linkage components inside the transmision slipped out of adjustment where only a setscrew holds it. The shifting fork doesn't seem to move the gear all the way into the detent in the guide shaft. The operator lever hits the sheet metal before it can pull into position all they way.

 

[windyacres77]

Well only being held by a set screw doesnt exactly sound like a very good setup. Wonder how many other tractors have had this problem, kinda sounds like if that set screw is not very well tighten at the factory this would happen? Well how big of a pain is it going to be for you to get the two gears out? Can you pull both out from the top like that. I am thinking you have to split it at this point, could be wrong I have never had a mahindra apart?

 

[mboulais]

Step 23: cover with rockshaft assembly off.

Step 24. loosen bolt (setscew) on PTO shifting linkage and pull that linkage off the shaft

Step 25: loosen bolt on shift fork guid bar and drive the bar backward out of transmission housing

Step 26: remove bolts from retaining plate around pto shaft at rear of tractor. pull the plate off. pull out the seall under it.

Step 27: remove snap ring that is exposed now that you have removed the seal. pull / drive shaft rearward out of tractor. rear bearing comes out easily. Front bearing can be tapped forward off shaft after it is dislodged from its socket .

Step 28: Remove fixed drawbar . this exposes the rear end of the drive shaft.
Tap the drive shaft out of the back of the tractor.

Dissasembly is complete!!!!!

I could not have done this without the parts diagrams on this site:

Marcel,
What you have done here to help others, with this problem is unmeasureable. I as a dealer, have not even had to deal with this problem before, and what you have posted is a great help to me and I know this is also very helpful to Windyacres as I am his dealer and I didn't have the hands on experience which you have supplied. Hats off to you!

Thanks.... Want to sell me some parts?

Thanks.... Want to sell me some parts?

I would be glad to.

 

[mboulais]

Parts came in! Still waiting on filters, but I can move forward with this

drive shaft assembly went pretty well. Big bearing went on easy, but I needed to get to a press to install the small one. The assembly slid in prtty easy, I supported the mating shaft with a nylon sling while lining them up. after the shaft was in place, I tapped the seal /cover in and bolted on the drawbar.
