Hinomoto E324 Injector Pump / Priming

[iloveketchup]

After a long battle with a clutch, i can't get this thing started.

I cracked a single line, no fuel when cranking.

I cracked all lines, no fuel when cranking... nothing

There has got to be air in the injector, fuel runs out of the hose if i disconnect it (the gas tank is higher).

I hear there is a plug on the injector pump that can open to prime? Is it the screw or hex head on this photo?



This is the position the fuel cut off is in:




If i unscrew the fuel filter, it starts leaking fuel immediately so I would expect it's full. The photo is before unscrewing

Thoughts people? I know squat about diesels.

If i use a whiff of ether, it'll knock (early detonation as would expect) and then move a little faster but still not start up.

It's a pretty simple process to bleed most systems. start at the tank and work your way to the injectors. This video describes the basics for most compacts. Just crack every juncture along the way and make sure any air is bled and move to the next. Restarting a Diesel Tractor After It Has Run Out of Fuel | eHow.com Small diesels ~can~ crack pistons etc with ether, I'd stay away from the temptation.

I was told there should be a bleed screw on the fuel filter assembly but i'm not seeing it...

There is an in, out and a vent that goes back to the gas tank. No screws like the video or how one would do brakes.

I'm still not sure which screw on the injector pump is the bleed either. The large one (photo above) with the regular (-) on it doesn't want to budge. I hit it with an impact screwdriver and it's not budging.

There is the hex head.. not sure...

there is another screw on the side that may be it (photos below):



the other side is the same (clamps)

I never ran out of gas, so my suspect would be air got up into the injector when i disconnected it. I have fuel flow when the fuel line is removed from the injector.

I don't know which is the bleed screw. If you can't get any loose to see....You can try to bleed the pump by cracking the injector fuel lines loose from the top of the pump and crank, crank, crank the engine until you get a steady fuel supply coming out of the pump, tighten the lines, then crack them loose at the injector end and bleed by cranking the engine until a steady fuel supply comes out and at this point the tractor should start.

i think it was the slotted nut near the injectors (a little discolored and low).

I cracked it and quite a bit of bubbling happens, but yet to cease getting air. I wasn't able to work on it much today due to another project but will try again tomorrow. Maybe if i bleed it long enough it'll stop bubbling.

While looking online at various forums trying to figure out which one was the bleed screw on your pump, I read of some instances of it taking several minutes of cranking to clear the air out of an injector pump so it's not always a super quick process.

I JUUUUSTTTT got it started.... it's the screw that doesn't have black paint on it.

Yes... it took a while to get the air out. I think what helped was i had it really really cracked and when i kind of snugged it up a little may have bled better.

The tractor is out of the garage and so far so good. One thing to keep in mind that scared me shitless was make sure the clutch pedal pin is hooked up and the clutch lever is pulled all the way out (not in). There is enough play in there to let the fork slip from the slide and then you have to work it for a while trying to pull it back into the right position... takes finaggling.

Thanks for all the help!

Sounds good. There are two things I have found that you may notice. After putting a new clutch in one time it was extremely grabby for the first 1/2 hr. or so of operation then was fine...I've only had that happen once but just thought I'd mention it. I've also ran out of fuel several times and after bleeding the system and got it restarted, it ran fine for a little while and then stuttered a little bit or even died occasionally for a little while afterwards. You may still have a little air that's trapped somewhere, so if the tractor runs a little irregular or even dies but restarts easily for the first little bit of run time don't sweat it, I think it's pretty normal.

Now I think the next project ought to be to move those rear tires to a wider stance and think about some ROPS.

The tires do need to be moved out... I think if i pulled them both off at the same time and reversed them it'd be quite a bit wider. When the tractor did run for about the first hour of ownership, i hit a few bumps and it was quite scary.

where could i find an inexpensive ROPS that would fit this?

"Inexpensive" is a subjective term. You can google "Hinomoto ROPS" and come up with several makes and sellers here in the U.S. and it looks like around $650 is the cheapest I saw on a quick search.

Ebay almost always has several ROPS for various makes/models at any given time for good prices and patient watching may produce a unit that could be easily adapted.

I built my own....a very controversial subject here on TBN. There is a ton of information concerning ROPS on the Internet to help a person decide if this is something they should consider or not.
