Them frame rail bolts are special tapered bolts like the front wheel lug bolts. r47953 bolts are longer at 2'' for this purpose. also there are two more back behind the batterys too check also!!
We had same problem on 4430 blade tractor a few yrs ago, a retired JD parts man gave us the fix, drill out threads with a 21/32'' drill bit, rethread for 4640 bolts, use thread lock, forever fix
The bolts that wore out the threads can be heli-coiled, that will allow using the original size bolts to replace the broken ones. The other choice is to go to the next size larger and tap the casting accordingly.
My bad! Locktightened fastners, is to heat the fastner which softens the locktite....not crazy cherry red heat....just 500deg or so with small torch....and plenty of time to heat soak all the way down fastner to where locktite is
There's a lever on the left side that allows you to put the transmission in tow or neutral, you then hook up your pressure guages to it and it allows you to shift through all 8 gears without the tractor moving, you can then tell what the pressures are doing in each clutchpack, if it was slipping in 7 and 8 before that's probably still gonna be there, when the oil is cold it's thicker and the clutches won't slip as much, but I've seen a 4640 slip in 7 and 8 and ran for years the guys just new to idle it back and then increase throttle, now you may have had something in the shifting value that was sticking also, if a value wasn't opening or closing as it should it would cause that, but I'm gonna bet when you get back to using it the problem will return Good luck man hope it works out
We had 2 4020s with power shift always slipped between 7 and 8 the first one we traded with 2500 hours the second we still have has about 12000 hours still runs like a champ besides that rebuilt motor at about 9000 hours.
The hydraulic leak that you fixed up front may have also contributed to the transmission working better if it was feeding oil and pressure to the transmission.
Very good video thank you for sharing
It's great Dylan's & Bob could help out , it's great to have real friends , thank you , stay safe everyone !
It's good to have friends. 😊
Love that 4440 sound!
Always great when you get a task completed. Can’t wait to see this at work!
Enjoyed the video Matt! Dylan an Robert are good folks. God bless
Great video very informative, I love LED lighting
New videos!! Goodie, Goodie.
Surprised Dylan didn't talk you into a straight crome exhaust! Lol. Really enjoy when yall collab.
Love the power shifts.

Nice work guys!
A trick to removing fastners

What size are the newer bolts?
@@griggsfarmsllc I don't remember, just 4640 bolts, best I remember they were tapered 3/4''
Done had to call in the big guns....I've never ran a 8 speed power shift that didn't jerk like hell shifting into 7 and 8 gear
Ya'll will love the LED lights.

Hole was egged out. Couldn’t put Helicoil in
Clutch it between 7&8. It’ll help you with your bolts.

Great video and a fantastic mechanic you have here. Do you know what temperature the transmission should operate at ?
I wood also check bolts from engine to transmission never no good thing to check
Maybe you did this already, but take the batteries out and check the frame to block bolts at the rear of the side rails .??.
Yeah we checked them too

Sharpie marks on your bolts
the fork lift with no brakes
What do you use dozer blade for?
Dirt work and pushing trees
👍👍👍🙏

What gears is the tractor slipping in and does it only do it when pto engaged
All gears. No does it without PTO on also
I have that exact trump 2020 flag in my shop
I guess I though @DylanJoyceFarms was there to chop that breather down and run you a straight pipe......
😆
I tried on the straight pipe but he wasn’t having it.
@@DylanJoyceFarms just sneak down there some day and slip one on.
@@robratcliffe5635 I've got an old 5-inch laying around that will make her billow
If you know anyone who would like to have a nice 4440 I have one
Are u getting another New Holland tractor ?
Not buying any tractors anytime soon
@@griggsfarmsllc you wouldn't make a good "turn-row" farmer. They have to get a new tractor or pickup every year.......
@@todd1808 probably not. Not my style
I'll bet. Minneapolis Moline G 1355 had the first air conditioning. And highly superior pulling power. But you go with that.
Big time difference
First time watching your channel. Love the TRUMP Flag
