Hi Basher (i am not sure if this is correct), I am repairing a 1908 Pilkington power hammer that looks identicle to yours.
mine has a broken big end so I need to dismantle the entire crankshaft arrangement.
I have tried to remove the crank shaft but it only moves about 1/2 to3/4 inch either way then comes up solid against something.
I am noy sure if it is just the flywheels that are stuck or something else.
Do you perhaps have any advise.
Thank you.
