430 Loader STILL not right.

joeblack · Jun 9, 2003

When I took delivery of my 4310 with 420 FEL I was giving it the once over and noticed the sight glass seemed to read almost full, with just a slight bubble at the top. I asked the delivery mechanic and he said it was because it was assumed I would lose some fluid during initial parking/mounting of the loader and it would keep me from operating at a low fluid level while I was "playing" with things. He indicated they would receive service calls about jerky operation when new and it was normally associated with low fluid levels which might be considered "normal" in the sight glass or air in the lines on the loader. I'm not sure if this really helps but your consistent input on this site has been invaluable to me so I thought I'd pass on that info. if it might add to the solution equation.

I am curious, besides the 13 inch (and change) reach advantage and a 63 pound capacity advantage, I'm not sure why so many people choose the 430 loader over the 420? Is it merely the 4 in 1 option or to have the biggest/best one for the given tractor size? Is there another reason I'm missing? I know it's off topic but appreciate your input and hope your loader will start behaving!

Well, I was thought Overfilling was a bad idea, although that might not be too much...

As to why the 430... My main reason is mini round bales. Deere OK's them for the 430, not the 420. That is what got me on the Deere from looking at NewHolland, where there was no way, due to front axle problems.

It might not have been that big of a deal, but I didn't want to wait to find out, and wished that I had, I woyuld surely have taken a big hit.

My dealer is sending the 430 install/prep manual, and checking on things. I will try and see what would be consider overfilling...

Thanks!

Talked to the dealer, he thought that the valve was out of adjustment. I can take it by or could do it myself with the service manual. A trip over will cost about as much as the manual. Is that barking up the right tree?

With my luck, I would buy the manual and still have to take it into the shop /forums/images/graemlins/tongue.gif /forums/images/graemlins/tongue.gif. On the other hand, you would have the manual for future use and may learn something useful in the process. Good luck. Hope it solves your problem. /forums/images/graemlins/cool.gif

Funny that the valve would get out of adjustment just because you changed loaders - unless it has to be adjusted differently to handle the higher load capacity for the 430 loader. /forums/images/graemlins/confused.gif

Are you sure the hyd fluid level in the trans. is not low and when you extend the hydraulics it makes it even lower. Kind of a long shot but might be worth checking into.

The tech at the dealership hooked the lines up, I merely swapped units (sorry for the confusion) He DID warn me to verify the proper configuation, since he wouldn't be testing it on the tractor...

The movements folow the manual, except that the boom stops about hood level on raise-, and the bucket isn't quite right.

Tonight it seemed that after cycling it through at 8'oclock position it would then work at 6. I still couldn't reposition the bucket while raised.

I haven't noticed any issues with the linkage (but am not an expert...)

Actually, the Hydro level is full up on the glass, I didn't intend to do that...

I saw in another post you are getting close to the 50 hr. break-in service. The suction filter may be getting slow or stopped up. Kinda of a long shot but could be.

rockyridgefarm · Jun 11, 2003

I may do the 50 early, just for hopes. At least I am going to track down the stuff.

The problem isn't terrible, but I want it going correctly

Mike, I've been mulling your issue over in my head. It certainly is a puzzler. I don't know if I understand the problem, is it an incomplete ability for the loader and bucket cylinders to fully extend? Have you ever checked the hydraulic pressure during the lift and what happens upon approaching the problem? I would assume you could use a hydraulic gauge and male connector plugged into one of the 2 lift cylinder lines on the joystick or where ever JD disconnects its loader hoses. I hope the remedy is near, Rat...

( is it an incomplete ability for the loader and bucket cylinders to fully extend? )

No they go all the way up; if I have the stick at 8:00 After a few warm ups, it seems to work at 6:00. They actually hit the stop pretty hard...

Once they are up, I can't move the bucket, I have to lower the arms about halfway.

I din't have a hydraulic gauge, I will see if I can borrow one...

Thanks!
