Hi everyone just got a question for anyone who knows about pajero 4d55 diesel engines.
I just rebuilt mine, i've only done about 1500 km so far but i'm not running the balance shafts.
there in there i just havn't put the balance shaft belt on, i don't think i need to run them.
Just wondering if anyone knows if it is fine not to run them.

thanks much appreciated.

All good, just makes the motor vibrate more. The belt snapped on my 4d56t and I didn't even notice it.

Ha... Don't have to run them!
Not trying to be a smart ass but Mr Mitsubishi wouldn't go to the expense of putting them there if they weren't needed.
People go to a lot of effort balancing motors to make them more reliable and rev more freely. You may not notice it to much but I bet your engine will be.

150,000km without them and no major issues, think that says something. All they do is stop vibrations. Nothing major really.

Thanks guys for the feedback, recken i might just leave it as is, everything is running good so why disturb it, i've done 1,500km not 150,000km.
