fuelpump for KM385 TE

I have a JM284, with the Laidong KM385 engine.  On mine, I have to fill the oil for the injector pump, thru the dipstick opening.  It's a long annoying process, but I know of no other way.  There should be a dipstick for that hole, only a couple of inches long.

Never tried that, and it's too durned cold to go out now and see if that is possible, lol

On mine the breather just unscrews with fingers and I add oil there.

janb,

Is this what you are talking about?

Mine has a vent cap, and the plastic cover will revolve around endlessly, but never un-screws.  Looks similar to the one posted but slightly different.

I am not saying your is like mine but my foton ft504a has a dipstick on the injector pump and its lubed off the engine oil pressure.There is a oil feed that comes off behind the oil filter and runs to the pump,then it dumps into the block at the front of the engine.

The Jinma's don't run off oil from the engine, just the Futons. A friend who helped with the crate assembly on my 284 thought the pump looked like a copy of a Bosch used by Mercedes in the Sixties.

Janb,

Can you post a picture?

If not, perhaps we can figure out your injector from the picture that I posted above.

1. Do you have the hole on top? (On mine it has a vent cap. On some it has a dipstick or cap.)

2. Do you have the 2 drain plugs at the bottom?

I don't have a dipstick and have never missed it.

The refill process is to open the 2 bottom drain holes so the oil is drained from the internal forward and rear chambers.

Put the drain plugs back in and SLOWLY fill with oil. It will only go in slowly without overflowing.

When the oil begins to drip out of the fitting in the left of the picture, it is full. (On mine you can see a small tube just under the bolt. On some I believe that that the bolt needs to be removed to allow the oil dripping to indicate a full condition.)

Since the oil moves so slowly through the system, I then let mine sit for several hours until that dripping oil stops completely (since you do not want the system too full of oil).

Well if nothing else Circle G should be able to give you specs on that dipstick to make your own.

If I can find my Micrometer and the batteries are still good I check mine and give you the specs.

janb,

I think that you are trying to fill it too fast.  The oil has to go in very slowly or it just comes right back out.  I have to use a large syringe type of device so I don't try to get too much in at one time.

I must be losing my mind Jan. I thought it had a dipstick, it does not. I personally did not fill it, a friend did that part, and he remembers removing a bolt (like Ron's picture) and filling it like that.

janb.

One more thought – when it is that cold, I suggest that you get the oil up to room temperature before trying to put it in that injector pump.  I can't stress enough the need to fill it slowly.
