Any JD 4700 HST mechanics in here ?

[Hoss710]

it's a 2001 4700 with HST. they ordered a transmission pump for it. but still haven't split it. I told them to order a swash plate bearing as well. my 4320 with e hydro has given me little to no problems. I had 1 proximity switch go bad. a quick replacement. and no other issues.

Ok it's been 7 weeks since I dropped it off at the dealership. went there today and was told the transmission mechanic from another of there locations, will start the teardown at there location on Monday. Really hope he doesn't get sick or catch covid between now and then !

they started splitting the tractor this afternoon. they should have it separated by mid day tomorrow. talked to the 1st tech. he stated that both forward and reverse max pressure was 1000 lbs . but he also said that he believes he heard either the relief valves or possibly the pump squealing with the brakes held and pedal depressed forward or reverse. the have a new pump and swash plate assembly on hand for the repair.

OK another update. young man split the tractor on the rear side. not engine side. so it will have to be split there as well. he normally works on the 1000 and 2000 series which has the transmission in the rear. everything looked good. nothing worn or damaged in the rear section. hopefully by Monday he will have the transmission out. screen did have a small amount of fine metal in it. but nothing crazy or excessive.

a few more pictures

Went by today. they had the transmission out. lots of metal inside. needs both pressure pump. and hydraulic motor. a few bearings and some seals. some of the parts are no longer available from deere. so this could get interesting. if all parts were available that would be around $6600.00 just for parts . they also found the rocker shaft wasn't assembled correctly and was rubbing the housing causing metal shavings. I have tried to find a used transmission for possible spare parts, but no luck. and John deere doesn't have replacement transmissions for it anymore. they were discontinued a bit more then a year ago. they had cleaned most of it up by the time I got there . but had shown me a few pictures of all the metal they found. but I did take a few pictures.

So my dealership was able to locate all but 2 wear plates to rebuild the transmission. the wear plates had minor wear. so I was able with minimal work lapped them in and they look good as new. all parts should be there by Monday if not sooner.

Sounds like you are doing this at a non-JD dealer. By the looks of the "shop" and your recent post. That right?

nope it's a John deere dealership. Atlantic tractor in Mechanicsville MD. very small shop. there use to be a bigger John deere dealership nearby. but Atlantic bought them out. there service area was about 4 times larger.

have another update. it's back together. but not 100% yet. but should be Monday sometime. then they will test it. and if all goes well the new 440R loader will go on .

forgot to mention when we got it all apart. the wiring harnesses were all eaten up by mice. luckily JD still had them in stock. those buggers get into everything. I'm hearing dryer sheets are the trick.

One hears that dryer sheets work, but have yet to hear that there is any proof. Am thinking it is just a tale.

But mouse poison and traps do work.

Also, I've found that spraying the nesting area down with a bleach solution covers the urine smell that lures the mice back to the nesting location in the tractor. Have yet to find a repeat nesting or wire chewing since doing that to my JD 212 in '75

Note that in the last pics there was some corrosion of the oil cooler, and was a known problem with the early 4xxx's due to the battery sitting so close and off-gassing battery gas.
Fix was vented battery caps and a hose to let those gasses release further below. Maybe a cleaning with baking soda and some primer/paint to stop the damage.

So stopped by yesterday. wiring is repaired. and covers going on.They changed the engine and front axle oils as I had asked. loader brackets mounted. so they are hoping to get it fired up Monday. and make adjustments. they did find a damaged injection line . apparently it was a issue with the 4500, 4600, and 4700s . JD had a upgraded line. so they replaced it. it was rubbing on a lift bracket at the top of the engine.

What do you figure the cost will be “all in”?

 

[Hoss710]

No idea. had them do other work while they had it split. found the 4 wd engagement paw had wear and needed replaced. they had to fix the rocker shaft assembly since it was rubbing on the housing. wiring work from the mice . as well as rebuild the transmission. Change the front differential oil , and engine oil. had them replace all rubber fuel lines as they were showing cracks , replace the steering cylinder as it was bent in several places . Replaced some cracked and damaged plastic body parts . I'm guessing I will see that bill soon enough. I believe the parts bill and labor will be fairly close. if all goes as planned, it should last me another 20 years lol . After I recover from the heart attack from seeing the bill. I'll share what the damages are. in for a penny in for a pound .

Another update. Tech was our Monday and Tuesday , went by there today and tractor is running. they are waiting for a tool to adjust the servo motor for the HST. IF all goes well I'll be picking it up next week towards the end of the week ( My work schedule has gotten very complicated recently) . On another note I had made a mistake when I ordered new side panels ( with new black grills) and hood for a John deere JD 4200 - 4400 ( instead of a 4700). if anyone needs a new set of aftermarket hood ( with gas door) and both side panels ( with new black metal grills for the side panels installed) . And you happen to be in the Southern Md, king George VA, and DC ( I work in DC area) and are interested let me know. I have a bit more than $325.00 into them. I'm looking for $250.00. Let me know. perhaps I may be able to meet up with you??

So is all running ok now? (Or did you tip over after you got the invoice from them?)

[Hoss710]

Nope they are still working on it lol. there is a long story about the bill. when I have time I'll add more details.

 

[rmonio]

Ok. Good luck with the situation! I hope it continues to move in the right direction for you.

 

[Hoss710]

Thank you! as long as it gets fixed, I'll be elated !!!
