I have 1998 excavator 345bl engine 3176C AND IT GET OVER HEAT after 30 minute of work what can I do to stop the over heat


Not fully conversant with this engine but generally causes of overheating are the following;
not enough coolant in radiator
sticking thermostatic valve
blockage in cooling system

Make sure radiator and reservoir have enough coolant, if reservoir / radiator don't get hot when engine is running then there is a blockage or the thermostatic valve is faulty.

Flush the coolant system with appropriate additive, refill and try again (you can for this use plain water without antifreeze But if it works you MUST ADD anti freeze afterwards.

If flushing system does not work you will have to replace the valve. Unfortunately I have no idea where that will be on this engine , apart from it being near the top of the water cooling systemand directly before any hose going to radiator.

Hope this helps

I have 345BL excavator and it start working after 30 m get inute itover heat


There are multiple reasons why an engine will overheat. Lets start with the basics:
1: check that the coolant level is full if it is low top it off with new antifreeze and check for leaks
2: Check to see if your fan belt is there and not slipping. A broke or slipping fan belt renders the fan weak or inoperative.
3: Check to make sure that the radiator is not plugged. Internally by looking into it and seeing if the coolant has turned to muck and also externally. If it is plugged with dirt and dust, it cant shed heat. If this is the case wash it out with a hose or blow it out with shop air. Just be gentle the core is easily damaged. A quick test for an externally plugged radiator is to run the engine and see if the fan will suck a rag to the opposite side of the radiator. if it wont its not flowing air and needs cleaned.
4: Your thermostats are stuck closed and need replaced
5: Your water pump isn't circulating the antifreeze through the system. Look in the radiator and see if you can see the coolant flowing or is it just sitting there.

Please can you tell me the year of a Kubota KX121-3SS excavator Serial number 30896 ?? Brian


here is a link for Kubota that may help you. It uses the engine serial # to tell you when the engine was built. It doesn't tell you when the engine was installed, though, but it should be very close to the same. http://www.kubotaengine.com/products/engines/engine-serial-number-identification>

How do I remove the engine on a IHI 35nx mini excavator to rebuild it


Undertaking that major a project, even on a "small" machine like a mini-excavator, should be done using an authorized service manual. I suspect with all of the hydraulics and other mechanicals you really want to be sure of what you're doing. If you're looking for a free service manual, I can't help except to say to consult your local dealer. An online source I found for a manual, albeit for a fee, is found here:
