L3400 technical details, how do I get them?

[StrangeRanger]

I've searched Kubota's site and different discussion boards, but can't find the technical info I'm looking for. I'm a hydraulics noob considering a TNT, but I'm having trouble figuring out just what I'll need.

My main problem is figuring out what I need to install the rear remotes. My L3400 has an FEL and 3pt hitch. I don't know where to tap into the hydraulic system or how many spools/valves etc. I need. Anyone got any pointers or info for me?

Thanks,
j

You'll need:
1ea BL7303 Hydraulic Valve Kit,
1ea BL 7343 2nd position Stacking Kit,
1ea BL7373 Additional Valve Section,
1ea L7303 Hose Kit,
1ea 75541-68150 Port Plug,
1 ea 75541-68160 O-Ring.
And some patience.

Assembly instructions are included in the kits.

I didn't know that a factory valve was available for the L3400. Is it ?

StrangeRanger:

Check out this thread on adding remotes and TnT to an L3400. Pretty much all the remotes I've heard about here on the L2800/L3400 are aftermarket.

I have not yet gone and done it. I'm too chicken yet to muck with the hydraulics and I'm not sure if I won't trade the tractor in a couple of years for a GL so I don't want to sink too much money into it.

For what it's worth I have a single Kubota rear remote on my L3400HST. I have attached a picture of where the hydraulic lines connect to the tractor. The tank connection was routed to the rear where the filler is. There is a new plug with a fitting for the tank return.

Here is a page from the service manual. I hope this helps.

The numbers I gave you are from the sales manual specifically for the L2800/3400 tractors.
I have a commercial customer that uses these valves for custom-built collapsable deck trailers. They are in the process of converting their fleet to L3400HSTs and really like the set-up.
The valves actually mount to the fender at the ROPs and are fairly simple, but they get the job done.

Thanks a bunch Todd.

When I approached one of my local dealers I was told that you have to go aftermarket. Not that I mind it because the aftermarket valves seem good.

Has your commercial customer been running a bunch of L3400HSTs already? How happy have they been with them - reliability etc. wise?

Try Carter & Carter for the TNT system. Basically is hooked up to the power beyond front loader valve with a return line to valve block at the bottom of your tractor. Unit clamps on to ROPS on right side.

I have the "Original" TNT from un-named person, unit is great!!!

i had a rear hydraulic hookup installed whn i got my backhoe, does this mean i could use that and just hook in to the new spool for the TnT using quick connect valves? this would make the job so much easier.. i wouldn't be able to use both (backhoe and TnT) at the same time anyway.

It's nice K offers factory stuff, but it's $$$$. If anyone is interested I took the time to look these up. Not sure if the dealer would budge on the price.
BL7303 - $376. Rear remote valve, 1st postion. "Required to install BL7303 with LA463 loader"
BL7343 - $25 Rear remote valve, 2nd position stacking kit.
BL7373 - $223 2nd rear remote valve
L7314 = BL7303 Hose Kit - $201
75541-68150 Port Plug - $Not listed
75541-68160 O-Ring - $Not listed

I think going after market may be the way to go. Thank you for the info though!

VERY informative link, thank you! I was stoked to see pictures of your finished product than saw your line that you've been too chicken to do it. LOL C'mon man, get crackin!
My wife/budget is the only thing stopping me at this point. I'm sure I'll be asking a ton more questions, but I'll be sure to log everything to share.

That's on the right side, right under your foot right? Ahh... I just saw your avatar, you don't have a FEL on do you? That's where I think my FEL is all connected up to. Is that where I can tap into for a rear remote though?

[StrangeRanger]

That's the exact system I was thinking of, the CNC system, but I was unsure if that "valve block" on the right side, under your right foot is a power beyond or what? I love being a noob

If you have the FEL you should be able to tap into those lines. It is on the right under the floorboard.

The L7314 hose kit is for an FEL application.
Non-FEL would use an L7315 hose kit and the price would be $232.00.

I think going after market may be the way to go. Thank you for the info though!

Kinda like buying auto accessories at Wally World for your $35,000 truck, but hey,
each to his own.

 

[bigballer]

what does the kit offer that can't be attained aftermarket?

thanks!

I dont see the problem with "aftermarket" parts??? i used vickers valves and eaton fittings and cylinders and weatherhead hoses in my setups. those are all "aftermarket" in regards to Kubota but they are top of the line in quality. Just because it doesnt have the Kubota name on it or come from a Kubota dealer it doesnt mean it is junk.

it doesnt matter where you buy anything from. some brands are cheap junk and some are quality products

 

[canoetrpr]

At least on the L3400 the Kubota valves don't seem to offer anything that is specifically better than an aftermarket valve. I'd be tempted to go with the Kubota setup if it had a clean mount of some kind.

Either way you are going to be fabricating a mount off the ROPS.

The neat thing about TBN is that the folks here make everything seem doable! Main reasons why I haven't done it yet:

- I've considered a move to a Grand L from time to time for no really good reason (which is why I talk myself out of it). Would be kind of a waste to get the valve and TNT installed and then trade in / move to another tractor. Don't think I will recoup much money I spend on mods to this tractor.

- There seemsss to be no clean mount for the valve. I'm not a DIYer so fabricating / welding something to mount the valve onto off the ROPS is out of the question.

If I can convince myself that I'll keep this tractor for the next 5 years or so then as a winter project I might take this on along with getting a sunshade and work lights installed (another thread I've got going).

I didn't say that........ maybe I used the wrong analogy, but I've found through experience, that sometimes trying to save a buck on the front end will end up costing a lot more before you are done.
Kubota offers a KIT which means you get everything that you will need to do the job.
Personally, I would rather spend a few more dollars up front than have to run all over the county chasing parts or waiting several days for the parcel truck to bring the 50 cent part I need to finish the project, but that's just me.
Sorry if I upset you.
