These are very solid reliable transmissions. There is a 3020 power shift on the dairy I help out on with well over 20,000 hours on it and the transmission has never been apart. It was bought new in 1967 and for years it ran the feed cart until the feed cart out grew the tractor.
Nice! You know member when a tractor got two five or six thousand hours and a guy had thought well it's getting up there in age. 30 years later these tractors have that 20-plus thousand hours and they're still going
Pretty cool to see how those power shifts work inside. I like the looks of that red one you've got sitting outside 👍👍 they're more my kinda tractor lol
Good afternoon, I purchased a 4640 this winter planted soybeans and started to do some cultivation with a 8row buffalo. I had problems with the pto lifting and so I changed the filters and it was full of glitter. It seems to shift fine but I pulled them out and replaced them. I did not change oil yet but I thought I could finish the field. I am changing oil. And second set of filters. Do you have any suggestions of where to test the oil and make to catch something before it goes south? Thanks
Your local Caterpillar dealer can do an oil scan, they sometimes can tell the type of metal and tell you it's a gear or bearing Could be bad brakes and the brake disk grinding, could be bearings on the axle or trans.
It's not bad. Off camera I told the wife I am saving what look like good disks because I honestly didn't think there was enough damage to cause the level of problem. After driving it I am tossing all of it!
@@dustinadams9136 almost. Got the hood wax.! I still wonder if I'm doing the right thing. And then I'm reminded that I was supposed to sell it a couple years ago
Hi Jon! Amazing work! Thanks alot for the tip,i added regular talc powder to my corn seed(1 pound per bag🙂),problem solved! I want to buy a JD tractor in the 135-150 HP range, full mechanical shifting,only with hydraulic HI-LO. The 3650 is 120 HP max from what i know,so it s a no deal.. Thanks for any advice!
Glad the talc helped!. Not familiar with the 3650, but if it's a similar platform as like a 2955 they can be a nice tractor, but that hp gets you a little out of range, can you find a 4250 kind of tractor?!
@@jonstevensmaplegrovefarms3754 Yes,i can,but it s a powershift tractor from wgat i found with a quick search on the internet. I want a very basic tractor,i have enough problems with a Case Maxxum 5140 tractor with powershift. Thank you very much for everything!
I have several 15 speed power shifts around here from cattle operations that are at 25,000 hours and the Transmissions have not been opened up With anything used you never know how it's going to turn out The 15 speed is very reliable and no electrical control. It is also a tractor that with a John Deere tech manual you could rebuild yourself. It's not the greatest loader transmission simply because you're always sliding that handle for shifting there's not a shuttle shift
@@andreipetrescu603 the quad range makes a better loader transmission because you can just shuttle from reverse to forward and it's still a good Transmission in the field. Pulsar rock-solid Transmissions that if they're in good shape you should get a lot of hours out of them
Funny how those are a hell of a lot heavier than they look. I had mine out about ten years ago to get the top transmission housing bolts out. I need to take it apart again to work on the hydraulic pump.
@@jonstevensmaplegrovefarms3754 nothing until you speed it up, won't even move.. ive forgotten and started dumping the silage wagon at an idle and it'll quit, then you've got to put some oil in it and wind it up to get it to go.
Luck had nothing to do with it. It was all Jon Stevens and the knowledge taught to him from his Dad. You make it look easy and especially with the new shop that has a smooth floor to move the jacks and gantry around with a load on them.
Thanks. That new floor, Oh man that is so nice! All that oil mess underneath the tractor of 5 minute mop and squeegee session and that floor is perfectly clean and you and yesAll the stuff Rolls so nice
So I got a 4640 powershift and the clutch pedal even if you hold it in all the way and you put it into to a direction it’ll creep forward any idea what that’s about?
@@jonstevensmaplegrovefarms3754 I was told one time that a 15 speed actually as 16 speeds but 2 of the gears are the same ratio so John deere made it so you cant use it.
My son has a 1961 4010 and the hydraulics seems slow and while lifting the implements chatter. Is there a way to test the main pump and transmission pump to figure out which one is the problem. Aloso this tractor is strange in that it does not have a priority valve. Where most tractors have a priority valve, there is just a casting to connect the lines. There is nothing inside but a drilled hole.
I have a 1980 540b skidder it has I believe the same transmission. Supposedly it has a new clutch when I push the pedal in all the way it doesn't fully disengage . I've adjusted the linkage to the pedal as much as I could to no prevail. any ideas?
I would put a pressure gauge on the clutch port, see where pressure goes when you push the pedal down. If that is going to zero psi with pedal down, could be damaged disks in c1c2?
This is probably trivial to your skill level. I have the 4440 leaking on the scv and it needs to get upgraded to the new style as well. If you happen to have a 40 series in the shop, it would be great to know where to start. thanks. I also think I need a 3rd scv with the planter.
We quit doing the pioneer (iso) conversion a long time ago. They always seemed to leak. Where is yours leaking? Around the barrel or out the hole where the hydraulic hose plugs in? Is it very easy to push coupler back and forth?
On these power shifts usually you get lucky and you have symptoms that send it to the shop before complete catastrophe. In M case is a couple Grand can actually go a long ways The first thousand dollars will just go to gaskets, seals oil filters basically just the parts to do the job.
hello, friend, I'm from Slovakia, I have a JD 640D, I have the same transmission, 7 and 8 gears, it works very poorly, and 1-6 only on the level of the charge pump, I have new ones.
Check transmission pressure, if 7 and 8 slip its likely in the C1/C2 area, If lower gears slip it's very tired transmission or more likely transmission pressure.
Honestly I would quote 8 to 10 hours to split the tractor and put the tractor back together and then I would have probably 4 hours quoted to disassemble and rebuild that clutch pack On a good tractor I can blow them numbers out of the water and maybe save the customer a little money and give myself a little bonus but if you run into trouble at least you've estimated a little bit of forgiveness in there
@@jonstevensmaplegrovefarms3754 any way you would have a parts list and possible estimate cost of parts. Just wanting to give a guy reasonable price on some side work.
Lol, yeah dad and I were talking this summer we need to make 3 sets of stands. The hoist works and that's what dad did for the last 30 years. I like the stands.
@ndrancher4041 1-4 in reverse are the same clutch packs other than the forward/reverse pack. So if you stand on the brakes in reverse and can't get it to slip, that tells us the gears clutch packs are good must be forward pack. But you say 5-8 work good. That is backwards, normally 7 and 8 start slipping first. That is a tricky one. I would start with a pressure test. Then watch pressure and go through 1-4 forward and backward and see if anything shows up. Keep going from there
@@jonstevensmaplegrovefarms3754 I figured it out! I made a mistake when I overhauled the transmission. There is a bearing in the rear end just above the pinion that I had the cup and cone reversed. The bearing loosened up and let the shaft wear out the little housing that has 3 bolts holding it into position. The little piston ring then leaked pressure off. Oops.

I wish I had the mechanical knowledge that you have. Those sound guard Deere’s are good old tractors though. Best in their day.

@@jonstevensmaplegrovefarms3754 4840. When you first start it you gotta run it wide open before it will pump any oil.
@@joemorse257 what would happen if you just started it and then walked away for a couple minutes oh, would you have steering and brakes?

Thanks for sharing that John!!
4320 is moving up the line very fast. I'll try and make that one fun and do a shout out
Nice 👍
John cool video question was the 15 speed PowerShift based on the 8 speed or was it a total new design?
The transmission pack is very similar but the sea 1 and 2 clutch pack and transmission pump we're a big change and for the better
