Like everyone else I am hoping to be out on the water soon so thought I would check my steam tug, fired up the boiler oiled every thing and ran the engines, and found one was making a knocking noise and was hissing and spitting steam!! The engines are Cheddar Puffins oscillating engines. Nothing else to be done other than take out the engines and steam plant to check out the issue. Long story cut short, one of the pivot pins ( second photo left hand cylinder) for the oscillating cylinders had come unscrewed leaving the pot to flap about, luckily it did not damage the port faces and I was able to screw the pin back in with a bit of lactate for good measure. Also took the opportunity to replace all the springs. Next came a rooky error, thought I may as well check and clean the pump valves at the same time, forgot to make sure to count the thread turns so as not to upset the lift heights for the pumps ball valves, so spent a happy hour adjusting the valves until the pump worked as it should so lesson learned. So thought I would share this and encourage others to check their wobblers!!! before use
