I had to make a special tool to remove the slotted nut inside the governor.The governor fits on the end of the FI pump camshaft and is on a taper.After removal i carried out some small repairs to the governor assembly including making 2 new pivot pins and some shim washers and bronze welding a small crack in the body (where that strange 3 piece spring is located).Also made a gasket for the governor end cover and whilst i was at it made one for the water pump too (which i have stripped and cleaned for a rebuild including 2 new bearings and seals and a new mechanical water seal and thrust ring).
Yesterday i removed the sump and oil pick up strainer and then all 3 con-rods and pistons.The big end bearing shells and journals all look in very good condition.And so today the time had come to remove the cylinder liners......the first one (nearest the fuel tank) was VERY tight and broke the bottom of my liner puller .Some welding repairs and modifications to the puller and some heat from my oxy/acetylene gas torch finally had the stubborn liner removed .The other 2 liners came out much easier .
I have cleaned the cylinder heads and recut the valve seats.The valves and guides and injector sleeves and a couple of core plugs will all be replaced.I will also fit 3 new injector nozzles and set the "crack of" pressures to my Zetor owners manual specification (2172 psi).Thats all for now

[QUOTE="stuzetor, post: 18462, member: 1615"] I had to make a special tool to remove the slotted nut inside the governor.The governor fits on the end of the FI pump camshaft and is on a taper.After removal i carried out some small repairs to the governor assembly including making 2 new pivot pins and some shim washers and bronze welding a small crack in the body (where that strange 3 piece spring is located).Also made a gasket for the governor end cover and whilst i was at it made one for the water pump too (which i have stripped and cleaned for a rebuild including 2 new bearings and seals and a new mechanical water seal and thrust ring). Yesterday i removed the sump and oil pick up strainer and then all 3 con-rods and pistons.The big end bearing shells and journals all look in very good condition.And so today the time had come to remove the cylinder liners......the first one (nearest the fuel tank) was VERY tight and broke the bottom of my liner puller :'(.Some welding repairs and modifications to the puller and some heat from my oxy/acetylene gas torch finally had the stubborn liner removed :).The other 2 liners came out much easier :). I have cleaned the cylinder heads and recut the valve seats.The valves and guides and injector sleeves and a couple of core plugs will all be replaced.I will also fit 3 new injector nozzles and set the "crack of" pressures to my Zetor owners manual specification (2172 psi).Thats all for now 8) [/QUOTE]
