Replacement engines for mini diggers.

[Le Sanglier]

Ok, so I think I cooked the engine on my Takeuchi TB016 today, which is a shame because I was loving the hydraulic thumb attachment.

Can anyone recommend any companies that supply replacement engines, recon or new. It's got a 3 cylinder Yanmar lump.

Thank in advance,

Mick

Sure you cooked it? Is it not rebuildable? What happened if you don't mind me asking?

 

Would have thought it would be no trouble to get hold of another though.

[Le Sanglier]

No prob, I was using the machine with the thumb and it slowed down and stopped with a lot of black smoke, (I hadn't noticed the temperature gauge) there was a hose leaking so I managed to replace it, let it cool down, filled up the expansion chamber and restarted. On tickover it's fine but once you start working it within a minute the engine warning light flashes, lots of heat, breather pumping out smoke, gets sluggish, was lucky to be able to nurse it back onto the trailer.

My best guess is that I've done the gasket and probably the head.

Got nothing to lose by stripping it down and having a look.

 

Do you have a comp tester for Diesel engines?

 

Would be an easy fix if the gaskets gone. Could be just that. Or the head has warped with the heat.

[Le Sanglier]

Yes I'll get the bloke to check it out, was preparing for the worst and trying to get an idea of price.

[Rich2484]

Well worst is the rings have seized. But as it was turning over they havnt. Maybe.

 

So my guess would be the gaskets gone and releasing water into the cylinders.

 

The black smoke could be oil from where the gasket has gone. Has it lost any oil? This could be the killer.

 

As he engine was turning over my guess is gasket. A quick comp test will verify it. And difference between two cylinders means its gone.

 

Once you have found the low comp cylinder repeat the test but with a table spoon of oil down it. Will create a seal around the rings. If the comp goes up drastically means the rings are worn. If no increase the problem is with the head. This could be gasket or valves. But with the overheating I would go with gasket.

 

But the most important thing is to fond out what caused the problem in the first place. Wy did it get that hot? Was there a failure elsewhere. Like the rad or fan?

[Le Sanglier]

Thanks Rich, plenty of oil in it still but leaking engine oil from soimewhere underneath, never done that before, all speculation I guess till someone has a look, I am not without knowledge on motors but these engines are tucked in so tight that it's a real pita.

[Rich2484]

No problem. Keep us posted. I'm intrigued now.

[Matthew Storrs]

Yes, I too would be keen to hear the outcome of this as I have a taktb016 and wondered what I would do in your situation. I agree, the engine bay is a swine to get to.

There's a firm by me that sell on ebay or off! They have lots of used yanmar and kubota engines. Google weldhall, they are near melton mowbray
