I've now got my 850 5-speed fully rebuilt, and I wanted to give a HUGE THANKS to you for the three videos. I watched each of them several times over, and it was truly invaluable information. Great job producing them, thank you !!!
Excellent info. I’m currently working on my 4000 with the 5-speed transmission. Is there a replacement for the clutch shaft spring? I’m having trouble finding one! Thank you!
Should the clutch pedal have a 1-1/2” play before hitting resistance? What should the distance be from the foot board to the top of the clutch pedal? Everything has been reassembled (thanks to your videos) and now I am looking for final measurements for my clutch pedal. Thank you!
I dont have my manual at the moment but from memory there should be 3/4" free play and pedal height is 9-5/8". Height was 9" something but I can't remember exactly. Thanks for the comments. Glad the video helped you.
Service book for my 861-D says 1-1/2" of free play and 9-3/8" pedal height for a 5 speed, live PTO transmission. That being said, it isn't possible to adjust my rod to get the pedal that high with that much free play.
Hello, I hope you’re doing well. I have a question if you don’t care to answer . I inherited a Ford 850 tractor with what I believe is the same transmission as what you are rebuilding. My problem is that it likes to pop out of gear. I can’t remember which gear my uncle said likes to pop out, but I know it’s either 2nd or 3rd. Some people say that it’s a detent ball that is worn, but watching your video I didn’t see any. If you get a chance respond. Thanks!
It's most likely 3rd gear that is popping out of gear. On the left side of the transmission you'll see 3 flat head plugs. Behind those are the detents. They aren't balls but more bullet shaped. The top one is the 3rd/reverse detent. The bullet tip may be worn or the spring may be broken.
@@chickenhousemechanic That’s a similar explanation that and old ford mechanic told me. I’ll have to open it up this winter and see what the problem is. Thanks for responding!
I change those in the subassemblies video. Here's a link to that video. I work on the seals around minute 20 in the video. m.ruclips.net/video/FsKIeKllge8/видео.html
I've seen the PTO input shafts available new but not the transmission input shafts. I've ran across a few on ebay that look nos but are for the non-live PTO 5-speeds.
Also what about the oil seal retainer/throwout bearing retainer? I have a new one but am having trouble figuring out does it need an oil seal and a needle bearing inside the retainer?
hello, I have a ford 5000 and I have a problem with the R gear. The transmission does not put R gear neither in operation nor stopped. and the gear lever does not move in R gear. What is the problem? 
I'm not familiar with the transmissions in the 5000 model tractors. However, on a recent Facebook group, someone had a similar issue, and others told him the shifter inside the transmission is most likely worn. As for general transmission knowledge, I'd say if you only have an issue with reverse, it would be something internal to the transmission. If it was every gear, I'd look at the clutch.
Deleted my first comment since I reread your question and I think I understand which one you're asking about. On the input shaft there are 2 seals. The small one that's inside of the PTO input shaft is a SKF #10515. The larger seal that's in the throwout bearing retainer at the rear of the PTO shaft is a SKF #19831.
First gear is the largest gear on the main shaft, the one on the bottom of transmission. It's actually the 2nd gear in line as the forward most gear is the PTO drive gear.
Yes. Just make sure you have the correct clutch and flywheel as the live pto requires a different setup compared to the non-live pto in an 850 tractor.
Jumping out of gear is usually a detent but not going into gear would mean something is bent or broken. The transmission on your 850 would be the same internally as this one with the exception of the input shaft. You'll have just a single shaft. Everything is set up the same with the exception of the bearing preloads I mention in the video.
I tried filming it but my hands were in the way so much you couldn't see anything. I used a prybar and screwdriver to roll the spring around the tab. Set other tang onto throwout bearing fork first.
I set the larger tang first then took a small box end wrench and pried the other tang on the fork. My problem is I still don’t enough spring tension to lift my clutch peddle up. Any ideas what could be wrong?
@fredschaefer9200 the spring could be weak. The clutch itself will push the pedal back when it's installed in the tractor. Also make sure nothing in the linkage/shafts are binding.

Thank you. If yours is anything like mine it's smooth as butter shifting. Glad they were able to help you rebuild it.
Excellent tutorial. Keep up the good work
Great work. Thanks.
Nice work!
Great informative video. Well done. I have an 861 and a 661. My favorite tranny on these model tractors.

That NDA7288A shifter seal crosses over to a SKF 6125.

I did not see any input shaft seals. What keeps the transmission oil from escaping and entering the bell housing area? Did I miss something?
I change those in the subassemblies video. Here's a link to that video. I work on the seals around minute 20 in the video.

Is the transmission input shaft able to be purchased anywhere? Having trouble locating one of those also

Also what about the oil seal retainer/throwout bearing retainer? I have a new one but am having trouble figuring out does it need an oil seal and a needle bearing inside the retainer?
Needs an oil seal. No bearing in it. PTO input shaft has a needle bearing in it. I cover changing those on the subassemblies video.

Would you have a part number for the front pto input shaft seal that goes inside bearing retainer

@@chickenhousemechanic thanks for the info, I really appreciate it. Your video is great
Can you tell me, which one is the 1st speed gear
First gear is the largest gear on the main shaft, the one on the bottom of transmission. It's actually the 2nd gear in line as the forward most gear is the PTO drive gear.
@@chickenhousemechanic thank you so much
What is the of the size Woodruff key I have a 860 and their a lot of play that shouldn't be there
Should be a 1/8" by 5/8" key for the shifter handle.
@Chicken House Mechanic okay thank
@@MattSouthers-iv9ds you're welcome.
@Chicken House Mechanic that's what I have but there still play
@@MattSouthers-iv9ds the shaft might be worn out. Make sure your nut is tightening down good. It'll snug down on the taper.
that got dam idler gear
would this transmission fit a 56 850 ?
Yes. Just make sure you have the correct clutch and flywheel as the live pto requires a different setup compared to the non-live pto in an 850 tractor.
Thanks and flywheel is different right ?
@@chevellejon8 Yes. Both the clutch and flywheel are different.
My transmission has started slipping out of third gear and will not go in fourth or fifth gear !!
Jumping out of gear is usually a detent but not going into gear would mean something is bent or broken.

It would be nice if he showed use how to put spring on. He skipped over the hard task.
