Central Kansas | 6 weeks ago I posted about the 1000rpm pto shaft for a 4010. On your advise, I just purchased a new 21 spline bolt on shaft. Just tried it and with the new shaft on or even no shaft installed at all, PTO will not turn with power. The 540 shaft pushes the spring loaded pin in and I do have 540 power. The new shaft has a hole in the center of the face where the 19 cent spring loaded pin goes into and contacts nothing, but nothing will turn, not even the front one. Soooooooo, now what is my problem?????????? |

SW Ohio | Hope this helps, this is a scan from a 1969 parts book. It looks like the 29cent pin pushes on the two gears #33 which would engage either the big 540 gear or the spring #30 should shift it back to engage small 1000 gear, at least that is what I get from a quick glance. I had a question back on your orignal post about whether some 4010's only had 540 with no guts inside for 1000, but a glance through the parts book shows a 540/1000 page and a 1000 only page and a none/ page

Martinsville, Ohio | I did that years ago. The small parts were the most worn. Really needed to replace the whole thing, it was my auger tractor. Karl Stroud has it somewhere now...

Central Kansas | This is getting frustrating as in my post 6 weeks ago,I thought that I understood that the 1000rpm is ALWAYS available and by pushing in the pin, that shifts something to create the 540 speed. As it is right now, I have 540 and absolutely nothing with the pin not compressed.
I pulled the pin all of the way out and rotated the contraption that the bolt on shaft attaches to, thinking I could get it to "fall into place" and thus have 1000rpm's but no luck. I am really at a lost on this one! Tomorrow, I will put the 540 shaft back on and observe whether it might be turning at a 1000rpms............even though the pin is compressed.
Any more help would be appreciated....Thanks

Brazilton KS | I will look at the service manual and see if it is more descriptive. I've never seen 1000 not work. My experience is not tremendous, but it's wide enough to have seen 540 that did not work at least three times. Does the pin come out all the way? I'm not sure what returns the pin. Presumably there is a spring somewhere that does that. You really need msb or ronm....they are the ones with lots of older Deere experience. |

Moran Tx | How long is the machined stem that is to the rear of the oring groove?
I install a 540 block in the 4010 and 3010 tractor pto to keep the owners from breaking the engagement pin, but they are the ones to give me the OK to do this, I do not know of anyone else that does this to the 4010.
Do you feel any spring pressure when you push on the center rod?
If you do then the shift collar should be engaging the 1000 gear.
With the pto shaft off push the rod in and as you let the rod out slowly have someone turn the front shaft and see if they feel the shift collar engage the gear.
Also when you have the 1000 pto shaft on and the pto lever in neutral can you turn the output shaft?
If you can not turn the shaft then the shift collar is not disengaging the 540 gear.
Refer the previous post that has the parts picture, you can pull every thing out of the center of the pto shaft except the piece between the shift pins, if either of these pins are bent they will eventually break and the tractor will have to be split to repair. Hope this helps |

Central Kansas | Bill...the pin pulls out to almost 1 inch in length and come to an abrute stop like it is contacting a flat surface on the other side of where the shaft bolts on to.. The drilled hole in the 1000rpm shaft is 1 1/8 inch deep.
Yes, I feel pressure on the pin when I compress it and if you turn the mounting contraption alittle, you can feel it engage.
If I understand you right, partial repair, if nessasary can be done out the back end BUT, if the pins are bent or broke, then the tractor needs to be split, is that right? Called my dealer and he told me that the only way to fix it if something needs repaired, is to split the tractor!....YUK! (another $1000 down the tube).......gonna be the most expensive 4010 around this area!...LOL
Yes, with the 1000 shaft on, I can turn the shaft by hand but have nothing with the pto lever engaged and the motor running. |

| It's a very easy split. When I was in good practice, I could have one split and back together pretty darn quick. The most disappointing thing is once you get to the pins, it only takes a couple minutes to correct the problem.
I remember pto pins breaking, but I can't remember whether 540 or 1000 didn't work. I seem to recall people using pennies to shim the pin.
I wish I could remember more about it.

Moran Tx | Good Morning, Trakman
OK first thing with the 1000 pto shaft off can you pull the center pin all the way out should be about 3ft long?
That long rod pushes on the rear pin to engage the 540 gear, when you install the 1000 shaft with hole in center that lets the long rod move rearward under spring pressure to engage the 1000 gear.
What breaks the 540 pin is whenever the 540 pto shaft is installed and the mounting bolts come loose and let the 540 shaft wobble then most people just tighten the bolts back up instead of rotating the pto shaft as they are tighting the bolts, that is what bends the (39cent) pin and eventually breaks.
The block I mentioned is put in when I split the tractor and remove the rear (39cent) pin and spring. This is something the man I worked for (when I started turning wrenches) did to do away the 1000 drive gear most farmers here do not use it anyway. but doing that solves a lot of problems later.
Through my shop it would run about 400 to 450.
There is no outside repair unless the front spring is broken, in the front shaft there is a slotted head bolt or hex head bolt take that out and there should be a pin with a spring attached could be that spring is broken and not pushing the 1000 gear to the rear and engaging.
In the parts picture thread #'s 27, 28, 29, 30 are the pin and spring you should take out.
