Thread closed over a install of a Turbo?

 

[orangeandgreen]

I have a L3240 and can definitely relate to the low power on hills. This spring, I was spraying my CRP and the trips to the field packing 150 gallons of water seemed to be a bit aggrevating for the cars behind me on the big hill I had to climb. Climbed the same hill with bare tractor or small implement and went 15mph all the way.

On the subject of hydraulic use killing engine RPM, This summer I needed to lift a shooting house into position with my pallet forks and I was hitting the relief valve with the house a little over waist high, just wouldn't go any higher. I "adjusted" the pressure to 2900 and set the house up on the base, about 7' high. The next day I "re-adjusted" the pressure back to the published 2600 (2560, but I rounded off). With the pressure at 2900, I noticed more of a drop in RPM when using the hydraulics.
In my opinion, the raised pressure of OP's hydraulic system is adding to his situation.

couple things,

Fred: love your posting style and obvious skill level. THis thread was awesome, and entertaining. I hope you didn't leave for good I'd like to pick your brain on a few things. Also if you're ever up my way you're always welcome in my shop for a beer, we'd get along great.

1) Fred's 100% right on the ULSD to regular fuel deal. If anything regular fuel is 100% better for your machine. That whole only run on ULSD is load of horse **** brought to you by the EPA and it's minions.

2) I wouldn't be surprised if something is amiss somewhere, the RPM drop doesn't sound right to me. Anyway, if the tractors smoking heavy you're right on the money and you're going to pick up a ton of power with a turbo. Smoke is wasted power. I'm still shocked at how much mine smokes even with a turbo, I think it's do to the engine's indirect injection characteristics. Either way I want to play with mine also but don't have the time right now, I'm in the middle of an in-frame on my pickup.

How do you adjust hydro pressure? I need to do that.

Like many people I have watched this post with lots of interest but never commented.My opinion of Fred has changed from thinking he was just trying to cause controversy to understanding his point of view.I previously owned an L3240 with loader and backhoe and found it underpowered for the weight.It is one of the main reasons I no longer own it.I would very much appreciate Fred sharing his turbo install with TBN members if he would.I am quite interested in how it turns out.Good luck Fred :thumbsup:

needs a fuel filter

needs a fuel filter

This is one of the reasons we have 29 pages on a turbo install. The fuel filter is new.
Any other ideas?

Fred, How's the weather where you are? Cold here.

How it came about can be debated, but if your engine has an emissions system on the exhaust (EGR, DPF, Catalytic Converter, DEF, etc) running anything but ULSD can be a very expensive mistake...

And what is Fred's mistake?

 

[The Fred]

I think part of MY problem concerning power loss when I use hydraulics is the shimming of the valve to 3000 psi.
Removing the shim will be one of my tests once I get it running again.

So another question, IF I ruin the engine/trans/whatever and the warranty is void will my insurance cover the damage? They DO insure stupidity right? Would be no different if I ran the tractor into a lake or lit it one fire or????????????

Right?

Kubota sells a shim kit for the relief valve or you can use #8 or #10 flat washers from the hardware store. Need a 3000 PSI gauge so you know where you set it, don't just add a shim to increase it.

I was under the impression this was an interim tier IV machine without any of that garbage.

10-4 thanks man, I'll snag a guage. Is there a how-to anywhere? I have no idea where the relief valve would be located. A picture would be worth a billion words.

I am not sure what is on that particular engine, but as a blanket statement "If anything regular fuel is 100% better for your machine" could cause someone who buys a newer version of that tractor significant grief. Hence my statement that "if your engine has an emissions system on the exhaust (EGR, DPF, Catalytic Converter, DEF, etc) running anything but ULSD can be a very expensive mistake"

And what is Fred's mistake?

I am not sure, I do know that going from 2500 PSI to 3000 PSI at 10GPM raises the HP needed for the hydraulics from 17HP to 21HP (to push 10GPM at those pressures per the Surplus Center calculator) and if you are already using 20HP to move the tractor, adding another 20HP from deadheading the hydraulics will be problematic on a 40HP engine.

I think part of MY problem concerning power loss when I use hydraulics is the shimming of the valve to 3000 psi.
Removing the shim will be one of my tests once I get it running again.

Should be an interesting comparison.
Before you pull the shim, I might try deadheading the rear remote to see how much of a change it makes compared to deadheading the loader valve while watching system pressures with a gauge (IIRC, they have different relief valves)...

So another question, IF I ruin the engine/trans/whatever and the warranty is void will my insurance cover the damage? They DO insure stupidity right? Would be no different if I ran the tractor into a lake or lit it one fire or????????????
Right?
Fred

Maybe... I would read what your insurance contract says about intentional acts damaging the tractor and coverage for modifications breaking things. If you want an authoritative answer, send a PM to the user KTAC, that is someone from Kubota Corporate who deals with KTAC insurance.

Here is a thread with lots of good info.

Search for terms like "relief valve" "pressure increase" "hydraulic pressure" there are several threads

Sorry about the hijack...back to turbos

Insurance might cover operator error like running into a lake and such, modding with a turbo might get kicked due to the intent of changing the engine from stock; the insurance covers what you bought, not so much what you want to turn it into. There are all kinds of ways for them to kick a claim to the curb.

Thought the question would breed more hatred toward the Fredster. Always thinking out of the box.

The Insurance co. would probably look at modifications the same as they look at arson by the owner - denied.

Fred, glad to see you still posting on this topic. I am not able to help you as your well beyond my level of tinkering currently but I'm reading and learning and hope you get your machine to where you are happy with it. It is very frustrating buying a tractor and not being satisfied. Not everyone understands that there may not be a better alternative other than trying to make it work.

Kubota makes some great tractors but their not all perfect. My girlfriends bx is a great machine and I enjoy using it but I dislike my m series and have very few options to replace it currently. I'm working with it to make it better suited for my use but Kubota has a lot of fans that take any negative comment personally which leads to hostilities. I wish you the best and hopefully you are able to get your tractor to perform to your expectations.
