YM2210 injectors, fuel pump, problem??

[Fire260]

I can't answer that. Doesn't sound likely to me but maybe the pumpguy will come on board here.

Thanks winston1.

The only thing u can do is, put a clear piece of fuel line from the inj. pump inlet to whatever is in line next..
& SEE if your getting any air at the inlet.. if not.. what about a stuck OPEN injector?? forcing compression back into the injector??
I've seen that happen, but it usually prevents the engine from starting..
To check, pull the stop.. & spin the engine w/ your finger over the injector where the steel line hooks to it.. u should be able to feel "air" if its allowing compression back up thru the injector.
How about fuel flow TO the inj. pump?? unrestricted..??

So i tested things out, No air leak at the injectors, Put clear hose from filter to pump,got all air out. Start up and in about 15 to 20sec small air bubbles start to form at the inlet on the pump, give it throttle and the bubbles will go away, back to low throttle,the bubbles will come back and start working up the hose to the filter. :confused2:

Bypass the Filter with the clear line from the Tank to the pump and see if it still happens. Could be the Filter Assembly could have a leak. Doesn't do it then you know you can pretty much rule the pump out. Put the filter back inline and it does it not much doubt Fitler problem.... Still does it period Inj. pump. See my point.

That was the plan for tonight.
Thanks for your time and help!

If you do that it might be a good idea to stop by the hardware store and pick up a B&S lawnmower fuel filter to temporarily bypass the suspected filter but still assure that only clean fuel reaches the pump.

That's what I found on my YM240 when I bought it. The previous owner had discarded the entire fuel filter assembly. (I soon replace this with what belonged on there).

For anybody that cares - this photo also illustrates how the US Yanmars' throttle lever is opposite the Japan version. Its push to accelerate.

I already have a filter to run on it for testing, i dont want to create more problems for myself.
Thanks for your time and help!

Any update?

At least that filter looks clean and like it was recently changed...or did you put that new one on there before you got the correct assembly?

Good eye. That's the fresh filter I put on immediately after I bought the YM240. This replaced a similar generic one that had a blob of water in it.

Then I went to the local VN import wholesaler and bought the genuine filter assembly complete, off a salvage Yanmar. But its filter bowl turned out to be a size Yanmar never used! So I had to get the bowl and element from Hoye before I was back to stock. Here's an old post where I described dealing with the VN wholesaler. They were good folks but they had to take back so many warranty claims that they had a row of pretty, but useless salvage tractors out back to keep them stocked with parts. Poor quality shipped to them from their factory in VN finally drove them out of business.

And incidentally that linked thread has some of the all-stars of back then. Inspector 507 and Soundguy, this group's founders. and Wayne of LMTC, a small dealer who was always helpful with advice but eventually was driven off by ignorant and insistent arguments from a wise-a*s.

Wow I remember all those members. Everything shutting down for Wayne sure seems there was a lot more than one guy going on with a Smart Butt!! I'm still thinking about that one. I thought of him when soundguy just came up.

Yes,I got frustrated with this tractor and needed to work on something else so I didn’t ghost ride it off a cliff. So what I found was, my filter housing was leaking,I ordered all new seals for it when I did the motor rebuild,but the O ring that was sent to me don’t work with my housing and leak air like a sieve.So put a different filter on and I still get air in the fuel ,so must be the pump.

So what’s so hard with rebuilding this pump, do you need special testing equipment? I was thinking I would take a look at it and see what’s wrong with it. Worst thing is I will need to get a new one.

You really need to know what your doing. I have been around here 10 years or more. Only heard of one guy on here that successfully rebuilt his. Now they can be done. Thepumpguy has rebuilt several here in the last few years when they have been needed for folks on here. He offers a mail in type service on your pump.

After following along on the guy who did his, it's no wonder most people send it in. All kinds of small parts and intricate assembly of parts. If you have done one before or been into that type of thing, then you probably can do yours as well.

This is uncommon. I've been around on here a few more Yrs. than Clemsonfor and I think there has been but a few Inj. Pump problems. At least you found the problem or Pump problems. With that being said it almost sounds as if someone may have been in that one!! Don't get frustrated you got it!! It just boils down to Repair the Pump or Replace it. If it is Repairable? Personally I'd be hot under the collar also and it would be my luck that it even being so rare it would be mine that done it. I seriously would check into replacing it. Something Stinks!!!!! I would almost bet money someone was in that pump. JMO......

I am saying that I only remember one pump that an owner disassembled and fixed. I remember a few more pumps that had issues. Usually the rack stuck or something. But as far as ones that needed to be fixed, yes that number is probably in the single digits that I can remember.

I'm shaking my head now. Hands down if it was mine Replace it!!!! And really had to stop from adding a couple choice words for the pump... May have Pumpguy check into a replacement and then go through it and then you would have done all you can do. That would take care of it I would almost Guarantee it...

THAT pump is NOT a good one to cut ur teeth on.!!
Your best bet is to send it off.. & DONT open it up..
Hoye "might" have 1.?? but you'll pay more for it, than getting yours remaned.. {depending on WHERE/WHO u send it to.}
My "guesstimates" are for a pump that hasn't been touched by the customer..
If I get 1 in "bags".. the price changes..{lost, broken parts}
& if it was EASY, everybody would/could do it..

 

[careyo63]

The 2210 Fredricks Refurbishes. My parts only show the bleeder Screw Assembly which that's not good. Only a hand full of models is on top of that which they do Refurbish also. They maybe who you need to talk to for Parts or Pump Availability. My guess they have the pump...

Seeing bubbles in the line doesn't mean much, most diesels will have a small amount of bubbles in the line, you will beat yourself to death chasing them.. Vapor bubbles are normal to see in a diesel fuel line..

But he is having runnability issues. We have confirmed it's not the first/filter assembly or the injectors (new ones). The only thing left in this system is the pump. If the thing is not running right, pump is off.. timeing or it's ability to make pressure.
