Hatz diesel engines 4m40l

[swinny]

Has anyone ever had any dealings with the hatz diesel engines at all?

 

We have a piece of equiptment fitted with a hatz 4m40l engine.... When we bought it we didn't notice any smoke etc but it could have been there..... Machine wasn't maintained too good. Blocked air filters etc and needed a going through. 

 

Fully serviced now, new oil air and fuel filters job lot. Originally it didn't have an air filter pre cleaner fitted either..... So all the crap would suck straight in airbox and clog filters. Now I've fitted a airbox pre cleaner like off an old David brown etc ....

 

Noticed the engine smoking black smoke a bit when using it. Esp if you rev it up all at once. 

 

I possibly put it down to machine being  Stood for a good while also and need a good blowing out. Smoke seems to be better after running it for a few days but it's smelly ... Yuck

 

 

To me the machines is smelly and runs rich! Thought of some stanadyne fuel system cleaner but wondered if anyone has dealt with these engines in the past and knows if fuel governor can be altered at all?

 

Like I says it's smelly and not too nice. 

 

Thanks Chris

Sounds like it's over fuelling if black smoke, especially if the oil level isn't going down.

 

Is this the engine with a separate injector pump for each cylinder?  We had 3 of these powering Heizohack 6M30 chippers and the engines were the least impressive things about them.

Hi there,

 

Pretty sure it's just one injector pump, haven't had chance to properly look at it to be honest..... All there is is a lever that comes out of end of pump for revs that's all.... Strange setup, looks like it's got 8 injectors.... Don't know why

I must admit I think this engine is great.... Runs like a sowing machine and sounds sweet! Think it's 70 odd hours power. It's a 4 cylinder air cooled setup
