4110 Final Drive

[FreshRouteFarm]

What a project! It is looking great after all your work. I did a similar job on a 4110 but no where near as in depth or detailed as yours. Will be better than new when your done.

So more or less I'm finished with the restoration now. Only speedbump was the hazard light switch that was corroded beyond repair. Found it out when troubleshooting the turn lights that wasn't working and it seems the flasher relay was powered through that switch. Jumped it for now but I'm awaiting a new switch and everything will be in function.

It worked out great and I am beyond happy with my new tractor. Already received a lot of compliments on it from neighbors.

Here's some pics of it and also undertaking some first tasks for it.

After a couple of years of wonderful use of the tractor, it was time for a new axle related brakedown. I've put a few hundred hours on it, and only done regular maintenance and one welding of a broken parallell shaft for the steering, so the initial restoration really paid off.

Today however it was a bit less easy to do a quick-fix. Guess I'ts on me for using the FEL a bit to hard without proper rear ballast, so need to learn from that mistake. Half of the broken cross section area shows heavy rust, so it has probably had initial cracks prior to this.

I figure its the part LVU800249 I need to get. It looks somewhat different on the exploded view than the actual part, but can't be any other than that. So only need to find a US-supplier that ships overseas. It's insanely more expensive here.

OK, so allready I found some trouble.

It seems the part I thought would fit is actually not the same.

From the HAKO catalog (remember this was initially a Hakotrac (Yanmar) and not a JD (Yanmar) there is two different main versions to chose from. If i chose the first one, catalog is just like on John Deere. But if I chose the second one, I find exactly what my parts looks like. My power-steering cylinder is in front of the axle, not on the back at seems to be the case on JD.

Is there in fact two different versions on the JD version of this tractor as well?

Here how it looks on my tractor. Part #8 is what i need. Have any of you guys seen this version before?

Ok. Trouble again.

I bought locally the part mentioned above. Equivalent to $550 instead of $166 but what could I do. That problem solved and the tractor is running again.

However yesterday I ran with a cart full of boulders, approx 3500lbs in the hitch, and since I was running hard dirt road for a few km, I ran on high gear even if it was quite a load. I think this busted my hydro.

As of today, in high gear, it is very slow to gain rpm/speed and the pedal feels very hard to press down, and resists my pressing it rather than gradually following down.

Also even when I'm running flat hard road without load, I notice I can't get it to run maximum speed. If I push the pedal the final bit to the floor, it rather slows a bit and the engine looses rpm even with full throttle, so I assume it is building pressure in the hydro without managing to distribute it to the wheels/hydraulic motors properly.

My first quick-fix would be an oil change, but what is your opinion/thoughts on this?

Reading this thread from the beginning you will remember that this was a restore of a busted rear tranny to begin with, and there might have been already damage to the hydro which I've now worsened.

Have anyone restores the hydro on one of the these tractors with the Tuff-Torque tranny?
