After the completion of a new 195 diesel engine, the crankshaft cranked, it seems there is the feeling of the piston top valve, causing the pushrod to bend.Started we think it is caused by timing gear installation disorders, re-check the gear installation mark and found no mistake , After installation, but also adjust the valve clearance.But the phenomenon remains the same.Further analysis and observation turned out to be the replacement of the valve guide, the intake valve guide tube above the cylinder head plane is too high, when the valve rocker to promote the valve, the valve Not to the prescribed opening, the valve spring seat and the catheter offset, then continue to crank shaft, it will make the fader change
