question End of life Zetor 6718

[djsumcp20oldleawharfcouk]

Started topping field there was a knocking noise then smoke pouring out. Found hole in side of crankcase, by number 4, conrod broken and bottom part of piston and also weight ballancer.



I assume this is the end of my Zetor 6718.

Is that hole in the sump? or higher up. It looks curtains otherwise.

Hole is in the side, edge of sump just at bottom pf picture.

You may go buy an engine block, there is no way of repairing that hole.

Found these in grass today.



Where would I get a engine block and other parts in the UK?

If you lived in Ireland, I could get you numbers for places you could buy no problem. But you could buy one easier in Poland maybe and get it delivered. Like this one. https://www.machinio.com/?location=&page=2&search=zetor+engine#quickview/30573384

How was this counter balance fixed to the crank shaft, there are two threaded studs with like nuts but there is no access from other side of counter balance or crank shaft?
