RK 24 out of fuel

[dmklein]

So I ran out of fuel in my RK24. Filled it up. Went to start it . . . Started right up, but died after less then 2 seconds.
Contacted my local dealer - he suggested I might have an air bubble in the line, & I should repeated start it until the bubble was 'drawn' out.
After who knows how many attempts, Still no dice. Starts nice & easy, but dies after 1 1/2 - 2 seconds.
No difference where the accelerator lever is.
Any one else have this issuse, surly I'm not the only RK24 owner to run out of fuel.
BTW - the dealer is suppose to email instructions on bleeding the fuel lines. (waiting), should that fail,he did offer to sent his mobile tech unit.

You'll probably have to crack the injector lines and get the air out.

 

[dmklein]

Neal from Messick's says that is not a good idea

 

[agjones]

If that is the yanmar engine just find instructions on bleeding fuel lines for a similar size /age unit.

Any chance there's a priming bulb in line?

If not... Usually involves a wrench often 17 or 19mm to open the hard line where it meets each cylinder. Do them in order from nearest the injection pump to further away.

Keep a rag handy.

I had a Mitsubishi tractor. There was a specific sequence for bleeding the air out of the lines. Fuel flow from the tank to the injector pump was strictly gravity fed. The injector pump did not suck fuel, it had to BE there. Sometimes bleeding once didn't get all the air out and I'd have to repeat. Just a thought.

I have the RK37 that I have ran out of fuel with. I had the similar issue after refilling the tank. Not sure if the same process works on the RK24 but the RK37 has a bleed port in the fuel line that you open to allow the air to escape. Just open the bleed screw then turn the key on to activate the fuel pump. Do it in short 10 second or soi intervals until fuel escapes fron the open bleed screw. Once there is fuel escaping the air has been forced out of the line and the tractor should start after a couple tries. There should be something in your manual about bleeding the system after replacing the fuel filter........Good luck.

... There should be something in your manual about bleeding the system after replacing the fuel filter....

looked in the manual, all it says is "Bleed the fuel system".
There is a diagram showing the 'Fuel Filler Cock', But No indication of where to bleed.

 

[DonRybak]

I looked at the manual for the RK24 and page 5-13 as you said just mentions the "fuel filler cock". Kind of sucky instructions to the say the least. I would think that maybe opening that might allow any trapped air to escape but I don't see any mention to close it after letting it run for a few minutes. Hopefully another RK24 owner will chime in...........

Did you get it to run yet?

 

[dmklein]

Did you get it to run yet?

No & getting frustrated.
As noted, the instructions in the owners manual is spotty at best.
Went out this morning , tried loosening the bowl around the fuel filter - all that accomplished was to spray diesel all over. Still dies after 1-2 seconds.
The owner manual refers to "fuel injection pump cock" not sure what this is, no pic's in the manual. Found a leaver on what I think is the pump, moved it to the opposite position, no difference. (Spring loaded so it returned to the original position - doing my best not to compound the problem)
Looked up the instructions for the JD 1012R (same engine) - they say it is "self priming", so I would assume the RK24 should be to?
I'm at a lost here.
Trying to get intouch with the RK salesman, but he must be off, as no luck there either.

I you have fuel to the injector pump you are going to have to crack those injector lines and spin it until you get the air out.

 

[thclimer]

You definitely need to open the fuel lines to each injector, one at a time and crank the engine over until you see fuel coming out.

Here is a short video that describes the process:

 

[DonRybak]

dmklein, the video thclimer posted pretty well sums it up. I looked up the specs on your tractor to get the model number of the engine which is 3TNV80F. If you Google bleeding fuel system on Yanmar 3TNV80F there are several articles and videos going through the steps but thclimer pretty well nailed it. I think that'll fix you up. Good luck.......Don

Well, Finally got it started.
Would seam that the problem had little to do with the fuel system, But a blown fuse.
After having a fellow tractor owner look at it, & having tried multiple times to bleed the system, we came to the conclusion that the engine was indeed getting gas.
Looked the fuses - there is a fuse labeled E/G STOP that was blown. After we changed that fuse, Started right up - and more importantly (because had no problem starting the thing) Kept on running (Which it failed to do before!)

Question is what caused the fuse to blow? Was it the running out of fuel?

Thanks for all of your suggestions.
Kind of disappointed in RK though - They ghosted me!

I have the same problem with my RK 25 (same engine) Thus far no resolution. It blows every 5 to 30 min.

I'm having exact same issue, 2020 RK24 with 18 hours. Only difference is I didn't run out of fuel, I was just smoothing field with boxblade and all of a sudden it died. It will easily crank right up and run about a second or two then dies. I looked online and only found one YouTube video of a Rk 25 owner that had same issue and after much troubleshooting and back n forth with service he finally said it was some wire that was getting pinched and causing it due to some fuel safety shut off or what not. I'll try and find the video again but it wasn't much help to me so didn't pay it mind.
I would like to get mine figured out though. Any help much appreciated it's a practically new machine only reason haven't taken it back is local RK dealer is about 2 hours from me and I've been swamped wirh work.

Thank you,

I'd like to thank you for this post! You saved my bacon. I would never looked at that fuse. You got me up and running after one google search. Only 2 hours of down time. if your ever near Frankfort Ky I'd like to buy you a beer or two. I joined the forum just to say thank you.
