fuel pump problem?

[TYMinColton]

Hi, all,

I've posted some related electrical issues on another thread, but this specifically refers to the fuel pump (DAE WHA 1699-2052-300). The question is simple. If I disconnect the pump from it's connector and place 12V (from a battery) across the appropriate terminals, should it turn on? Does it make a noise when it's running? Currently, if I do this I hear nothing. If I place a light bulb tester in the circuit it lights, but still nothing from the pump.

I was quoted $135.91 for a replacement. Not sure if this is a reasonable price or not, but I want to be absolutely sure the beast is dead.

Thanks for reading.
Pete

I got my pump at a local auto parts store for around 50 bucks

ALKY - Care to share a store name and part number? Is the pump a direct replacement part for the TYM part from Dae Wha (i.e. cross-listed)? I'm about to pop the cover on the pump electronics to see if it can be fixed, but I'm guessing it's a solid state pump. I'll post pics if anyone's interested

Egads! Not exactly what I expected. The good news is (was) it's not solid state. The bad news is it's encased in epoxy. It's like looking at a prehistoric mosquito trapped in a chunk of amber. Without a dremel tool, some patience, and luck, this is probably all she wrote. RIP little fuel pump. . .

Gonna miss you :drool

I took my old pump n showed the guy @ the parts counter & he found a close match. not identical but it works!:thumbsup:

After replacing my pump a couple of years ago I found a "MR. Gasket" brand small electric universal fuel pump made for diesel at my local farm store. It was less than $80 and I'm sure it is less on line some where. The diesel one is green as opposed to yellow the gasoline rated ones. That and a couple of hose barb fitting and you would be good to go.
If mine ever goes again this will be my fix.

It should turn on and pump fuel back to the tank. I think any small 12V pump with the same size lines will work. I is not a high pressure pump. All it dose it prime fuel to the injector pump. If the tank was full gravity would probably carry fuel to the injector pump.

 

[TYMinColton]

Cool. I was coming to the same conclusion about the use of alternative 12V pumps. You are also correct about priming without a pump. Gravity, particularly when the tank is full can get er done. It just seems to take a whole lot of cranking to get her to fully fire.
Thanks Bud!

Check it out. Look familiar? $24.99 with free shipping. I've even some other alternative pumps for even less ($18.99), but I think I'm going to pick this one up, since it appears to be an identical part with different connectors. I'll let you know how it turns out. Certainly cheaper than the $140+ I was quoted for OEM.

Success!!

After replacing the fuel pump, and basically the entire glow plug system, she's cranked right up without a fuss. I will tell you that the pump is not an exact fit, and the mounting holes do not line up with bracket on the tractor. In my case the bracket is broken anyway, so I'm holding things together with tie wraps, but otherwise the pump seems fine. If you do go this route you will need to swap connectors. I just cut the wires and soldered the correct set of leads. Quick and easy.

That's great that you have it running again. Especially for a fraction of the cost for OEM parts. Nothing better than being able to diagnose the problem and fix it yourself.

 

[TYMinColton]

You said it. The unfortunately thing is I'm almost forced to become a bit of a shadetree mechanic. I'm hopeful that TYM corporate will start adding dealers and service in my area, but for the moment I'm a bit stranded. I got a great deal on my 273 and she's nothing but work hard, but sometimes I regret not paying an extra 4k and buying a Kubota (or Deere) with better access to parts and service. As long as the problems are electrical I think I'll be okay - anything more major and I may be you know where without a paddle. . .

Thanks for posting on this one. I went ahead and bought one of those fuel pumps you posted as a precaution.

 

[TYMinColton]

myyaz - FYI, the mounting holes are slightly different on the pump and the bracket that mounts the pump to the tractor. My bracket (3rd one) had been broken for years (vibration I'm told), but I just received a new one and it's not quite a fit to the pump. I'll solve it easily enough with 1 bolt and tie wraps, but I recall seeing a slightly different model that may have had the correct connectors as well. I just soldered my old connectors onto to the new pump and away she went.

Hope you never need a pump, but at least if you, you won't have a break the bank to get back to gettin er dun!

I saw your post earlier about the mount not fitting perfect and that is fine. It broke within the first year or two and I had to weld it. Been good since but If I need to drill some holes or weld on it again, I will.
