4640 steering pump repair.

[@kevinferguson4163]

Glad to hear you can spend more time farming and get stuff done. Like your videos. Hope you get time to do more videos

[@WarrMatster]

Doing one of these on a 4630 right now, definitely a lot easier to get out than the 40 series tractors.

[@mikeosterloh8439]

Impressive and can sing to. No bitching or cussing that must be the fresh air.

[@brettrace]

Good video. Im working on a 4255 and got to a point where i can't get the components inside the column back together, while in the tractor. It looks like you really have to take the whole assembly out.

[@jonstevensmaplegrovefarms3754]

That's the easiest.. To take the metering pump off is easy. To put it back together and keep the seal,washers in place and get the shaft into the pump is a challenge.

[@brettrace]

@jonstevensmaplegrovefarms3754 seeing that you replied after 4 years after making this video, i thought id let you know that i actually did figure out how to replace the column, while in the tractor. A 3" bushing under the big nut on top keeps the top part from falling down too far. Rebar wire wrapped around the bottom of the shaft (the part that goes into the steering valve/pump and through one of the 4 bolt holes of the steering column keeps the shaft, that slides into the valve, up and in the column. This keeps the internal parts of the column somewhat in place while you wrestle with bolting the hinge and spring in place. With the valve located right under the column, there's enough room to replace that seal on the valve. remove the wire that is holding up the shaft that slides into the valve body, slide that shaft back into the valve and bolt the 4 bolts back together. Then bolt the steering wheel on, drive it around the yard, feel proud about yourself, realize that oil is now pushing up the entire steering column. Stop, drink, and contemplate life. Apparently the valve body itself can have internal worn washers that cause pressurized oil to push out the seals in the first place. Still, once again, thanks for the video. At least i can tell myself i tried more than most people.

@brettrace love it!

[@PAFarms]

Nice. It may be green, but nice fix.

Nothing like the sound of a old John Deere running. 👍

[@busyonthefarm]

Really appreciate your videos involving this era of John Deere! Helps a lot! I've got the metering pump out of a 4440, on the bench already. Leaking all over cab floor and top of trans case. Point(s) of leak not obvious. I've read over the test procedure in TM1182 but, I do not have the gear to test properly. Is there a quick and easy way to test this assembly for leaks? Shop air in inlet fitting perhaps... I know that the low pressure line was leaking due to age and degradation. I've got all the o'rings and seals on order but if it's only this shaft seal that would save me a lot of trouble as I don't have alignment dowels for proper reassembly.

[@leeroyexcavator9149]

I am attempting this today to get it out. Mine is a open station 4030 so the steering wheel has been a bear! Had to get the fire wrench out and heat it so the the little plastic slip tube is now very much toast! But I got the wheel off now on to the rest of it see how it goes. 🥴

[@jonstevensmaplegrovefarms3754]

Ha! Good luck

[@leeroyexcavator9149]

@@jonstevensmaplegrovefarms3754 I got it all out and apart so now just clean up and putting it back together . I had to remove the clutch pedal on mine to get the column tilt bolt out. It was hitting the pto lever.

[@leeroyexcavator9149]

@@jonstevensmaplegrovefarms3754 You did say the side of the seal with the cuts in it or lips you called goes down right?

[@jonstevensmaplegrovefarms3754]

The Spring or lipside always goes to the side of oil

[@joemorse257]

I replaced that seal in a 4440 last summer. It fixed the oil leak, but I must have snagged a wire because 3 days later it went up in flames

mr Bill anyone with half a brain in their head would be glad to have me work on their equipment

[@nickwalston6531]

We have a 4630 that has had the metering pump rebuilt at the local JD shop. Once returned home the steering is extremely hard to the right and perfectly fine to the left. What do I need to inspect?

[@jonstevensmaplegrovefarms3754]

Early 4630 with the 20 series steering? They will have to do it again and adjust the valve clearance most likely

[@HaroldMoreland]

What is the torque on the 4 bolts and nuts that mounts on the box?

[@jonstevensmaplegrovefarms3754]

If you're using a 9/16 wrench it would be 35 lb

[@hectormillar9035]

hi jon i need to know the hydraulic oil level of a john deere 4020 i'm from chile

[@jonstevensmaplegrovefarms3754]

Welcome glad you made the trip from Chile! If I do a service here where you drop the oil and it changed the filters it would be about 11 gallons. It might change a little bit whether it's power shift or Synchro

[@leeroyexcavator9149]

My 4030 is leaking up by the steering wheel. I wonder if this is the problem with mine? My fix for the last year has been plastic folgers can wired to the column!! Lol. Cause they wanted 1000.00 for a steering valve!! 🥴

[@jonstevensmaplegrovefarms3754]

Good chance just that rubber seal.

@zinhlechonco3132 them are not repairable, the aftermarket ones that are claiming to be rebuilt have been very hit and miss you're taking your chances with a used one they're not cheap but in the long run you just get a new one from Deer if you do determine that that is your problem If that block gets hot quickly if it's not your problem now it will be very soon

@zinhlechonco3132 time to replace it. Might have other issues but that needs to be relaced

[@4065winchester]

Could this have been done without removing from the tractor? Remove the 4 bolts and lift the steering column up enough to change the seal?

[@jonstevensmaplegrovefarms3754]

I thought about trying it that way just to see.

[@4065winchester]

I have a leaky 4230 and wondered if it was doable that way.

[@brettrace]

​@jonstevensmaplegrovefarms3754, don't. I've come here to find out a better way to do this and now i think its just better to take the whole assembly out. Its seemingly impossible to line up the telescoping pieces in the colum while it's verticle

[@morleyperry7434]

how did you remove the steering wheel?

[@jonstevensmaplegrovefarms3754]

Put the nut on the end of the threads flush. Put your knees or lift with a hand on the steering wheel. The hit the end of the shadt with an air hammer. Pops them right off!

[@ryanreeder5897]

I googled for the power steering pump.. I don't need to hear all the shit you're doing to the tractor. Fuck me, everyone likes to talk too much.
