BX1850 Cold Blooded Beast..

[oldnslo]

As a fairly new owner of a Kubota I am not sure how well these little devils start but.... to me mine is a cold blooded beast.

Yesterday temperatures in the middle 50's had been working it pretty steady for about 45 minutes digging a hole with the FEL and moving dirt in general. Shut the machine down for about 10 minutes to do some hand digging and then went to restart. I had to use glow plugs for about 5 seconds to get it to start. It has Bio-Diesel in it which I know is a mistake but would that make this start that hard. Runs fine once started. New fuel filters & air filter less that 3 hrs run time on them.

On a different note: First time using the FEL with tooth bar for serious digging dirt moving and rather impressed with what it will do. I need to check system pressure since it seemed a little weak on lift capacity. When I get batteries for my camera will take a couple of pictures of the hole I dug that is about five and half feet deep to access my well connection.

Might have to call it my Kubagder:thumbsup: being Close to Wisconsin and all

When mine is cold, less than 30 degrees, it will start hard, but once it has been started, it will start easily up to two to 3 hours latter. Yours doesn't sound right to me. Check your air cleaner? Make sure you advance your throttle a little, don't start it at idle.

I'm running bio-diesel and it doesn't start harder, just maybe plugs up the fuel filter a little sooner. I think bio-diesel is O.K., it adds back in lubricity that high sulfur fuel had, but I don't like it in the winter.

Mine lives in an unheated garage, and about the only time it starts hard is when it's sitting for a few days with below zero temps. Dodge Man is right though, make sure you bump the throttle up a bit.

As far as the FEL lift seeming weak, what RPM were you running?

 

[bp fick]

Hmmmm... interesting. I have the same engine and it never acted the least bit ornery last winter. I do glow the plugs in a series of 10 second bursts. I don't know if what I do is right, but it always fires right up in the first few seconds.

What I DON'T care for is the cold hammering of the engine. Don't think one can do much about that though.

 

[oldnslo]

As far as the FEL lift seeming weak, what RPM were you running?

2,600 RPM. I could hear the relief valve squealing so I am either trying to lift to much or it is set to low. Rear wheels weren't lifting off the ground so I am leaning towards to low of a setting.

Agree on this completely. First diesel I have ever had do that when temperatures above freezing.

Will try to advance the throttle a little first to see if it starts any better. I know first start is always a glow plug and crank procedure. Never had a diesel that I had to advance the thrttle to make it start better before but I guess if it works.. don't fix it.

thanks all

Ive started my 2660 is 6 degree temps (F). Started fine and ran fine. Im sure the windchill was below 0. Just pre-glow long enough and your good.

 

[radioman]

I agree - bump up the throttle in colder temps. I rarely have to do it in summer. biodiesel is NOT a mistake so relax, I just wouldnt have it in tank in dead of winter when temps will fall below 0. Reason is, there are still issues with bio in winter gelling even with treated feul. I wouldnt hesistate to use it in spring,summer, fall.

 

[fish6942]

The only reason I'd bump the throttle on start up is to avoid the horrendous rattling sound I get from the hood and the front mower bracket (cold starts only).

I never put my throttle in the lowest setting due to the rattle - not when starting or even when idling after warm-up. It will always shake the plastic parts to death when at its lowest RPMs. I suppose I should tweak it to raise the base RPMs.

You say the lift is weak??? Are you at near full throttle??? Is it able to lift a full bucket of dirt???

RPM's around 2600, I have only ran it wide open briefly once.

Full bucket of wet dirt was a struggle, I could here the relief squealing like a pig and the loader moved slow. I was digging a hole to access the pipe at the well outlet so was digging down hill and still would not raise the back of the tractor. Usually this is worst case scenario to be using a loader other than side hill with it raised Will hopefully get time this week end to put a gauge on and check pressure.

The 1850 has some type of demand priority pump. Bring the rpm up to at least 2900 and see what happens.

When you say the rear does not lift, what type of ballast do you have???

Woods BB5 box blade 272 lbs plus my lard ***.....

Even with out the box blade on level ground it would not lighten the rear when lifting.

Priority flow if for steering and charge flow. Once this flow is met the rest goes to implements. Unless the relief valve has a tremendous pressure rise Vs flow I would not expect much change with lifting force but will try tonight and see what happens.

I had to run way more rpm on the 1850 than my other Kubotas. Hydraulics were useless at an idle which is quite high already on these engines. Mine performed best on the loader near full throttle. It seems that the demand did not kick to the loader unless the RPM was way up. Also keep in mind that the front tires are small and will only take so much loading.

About your loader;

you are encountering the "In Situ" resistance

referred to as suction resistance effect in wet clay and

muddy ground, or compacted soils of any type

exposed to freeze thaw cycles, snow and rainfall


(I have witnessed lattice cable cranes

being pulled over to ground as a result of sedimentation

and its resistance from the attempt to break the suction

of freshly excavated sediment dumped in a barge used to

transport it to a very close dump site by a clam shell

bucket system).



-of the ground and clay in your trench due to

the compaction and percolation of sand, fine dirt

and clay creating one cohesive mass and as a result a dense

material with few if any voids and the resulting suction resistance .

The loader bucket without teeth also adds to the resistance.


The squeling is normal when itis used in an application as yours making a

trench of that width and depth with out any bucket teeth.


If your raising the rear end of your tractor you are asking for trouble as a

hose or cylinder could fail and impact will occur and the resulting bounce.




I use a kerosene fired salamaned to warm all my internal combustion

engines and especially my commercial log splitter and block

heaters even during the summer months prior to start up.


It also helps the battery by warming it and improving its ability to deliver the

CCA the battery is rated for


my two cents

 

[rdsaustintx]

I never put my throttle in the lowest setting due to the rattle

Ditto.

I't should not lift if properly ballested.

 

[drag_slick]

I usually use my tiller for ballast and have never lifted the back end. Most of my loader work is done at about 2500-2700 rpm never had any complaints except slow loader operation below those rpms

More info on my BX
Loader lift capacity
Installed a gauge on the lift port for the FEL today and took some pressure readings VS RPM's. Transmission was cool today probably less than 70 degrees when I ran these tests.

At 1500 RPM could build 800 PSI Bucket would slowly curl
At 1750 RPM could build 1700 PSI Bucket curled faster
At 2000 RPM and above pressure was 1750 - 1800 PSI

I believe factory spec is around 1775 PSI if I remember correctly.

Other things I will also have to admit to. I wasn't allowing for the tooth-bar which sticks out an extra 4". Took the tooth-bar off to back fill the hole and it will curl and lift much better. Heaping full bucket was no longer a problem. Sorry for causing this debate.

Bio diesel: Problem here in Northern Illinois is that we don't know what the blend is. Pump states between 5 & 20% Bio. I know lots of people that run trucks that have never in their lives had as much trouble with filters etc as they did this winter. Several of them are trying to get some sort of monetary help for all of their repairs etc.

And now for the last dumb mistake, When back filling a hole with mud, don't drive on it with a full bucket:ashamed: I know better, just had another senior moment
