3400

[jimmyb1]

Just bought a 3400 ford (gas) with a pump on the front crank for the hydraulics got over a week ago and ran it for a little bit. Now, it sat for a week, when i started it ran fine, then tryed to use the hydraulics. Tractor makes an awful sound from the pump and the loader won't move at all. When I try to move the loader it makes a worse sound. Am I low on fluid, or is my pump junk?
Thank Jim

Check the fluid level. Was there any fluid leaking on the ground? Is your 1/4 inching valve open?

check oil level.

if it has oil, check pump outlet into a bucket.. next check out from valve.

Well it looks like my splines are tore out of my coupler, or my splines are worn down will have to tear it apart to find out just what is going on. Dang the bad luck, do you guys know what books do I need to repair an maintain my 3400 with a front end loader.
Thanks Jim

ford service manual would be where I'd put my money.

[jimmyb1]

Soundguy i looked the manuals up an it cost 609 bucks, is there a diff. manual to look for?
Jim

 

[Soundguy]

the i&t simply aren't as good.

perhaps try a reprinnt like jensales.. or one on cd.

if u can find one on a 3000 ford that will be just as good the only difference between the two is the front axles the 3400 is a straight i beam and the 3000 is swept back. u might be able to find a used one on ebay or amazon

 

[Soundguy]

yeah.. but that front end difference on that utility makes other differences.. like radius rods.. plus that front pump setup.. those are likely items he needs to see in detail... especially since he will be working up front to repair it.

I agree with used on amazon / ebay.. good deals sometimes.

the front bolsters or not no different other than the 3400 has two other bolts that goes into the oil pan and a service manual on a 3400 will not cover the front pump loader and backhoe they was not installed at the factory u had to buy the tractor the loader and the backhoe all seperate and the loader and front pump of a 3400 is the same loader that goes on a 3000.

 

[Soundguy]

the front bolster on a 3400 is D5NN3A042B

the front bolster on a 65-70 3000 is C5NN3A042G

and 70.5+ 3000 is D3NN3A042D or optionally 81845556

i know they are different part numbers thats why is said the only difference between the bolsters or the one for a 3400 as two more bolt holes casted in them that u bolt to the oil pan below where u bolt it to the motor

 

[Soundguy]

i think there is also a change for a mid mount mower.. etc.

i have never seen one with a mmm but it could be but i dont think they would have one on a tlb this size

 

[jimmyb1]

Was tinkering today an i found out that if i pull the splined shaft toward the pump it engages the splines, started tractor an ran just fill no noise an loader worked just fine. I could see the splines are worn down, I pushed shaft back toward engine an pump does not work an a ton of noise.
I had my wife do some looking for the manual an she found one for $155 will be here in a couple of weeks.

[whodat526]

sounds like u need to change the collar on the pump and change the shaft

 

[Soundguy]

the bolster that is.. the optional number i posted is for a bolster with provisions for front hookup of a MMM.. at least for the brackets anyway.

the bolster itself is basically the same.

I agree...yep.. or rig something with a pin or key if you can't find or afford the correct parts.

coupler shouldn't be too bad.. and shaft.. depending on style shouldn't either .

yea they aint to bad i just put a front pump loader on a 3000 which is the same pump and it cost about 80 bucks for the coupler shaft and the star coupler that bolts on the flywheel (they where all aftermarket parts)
