Default Cooper Bessemer

Need parts - cooper bessemer type GAO - 12.5X 16 i think - missing the cross head and connecting rod - there is a piston and rod in the engine - missing parts on the side shaft - any help will be great - engine is on a jerk line from 1935 and is still all together besides the missing engine parts - looking to restore the engine before it get scrapped

I got an email about this engine last week from Andy over at Dicks Engine. Was hoping I would see it on here
I wish I knew where some parts were for your engine but I don't
you may just have to get crafty and make them or modify some old Ajax parts

any help on finding parts or general information about the engine would be great i posted the name plate and some of the various flywheels in the shed that ran the elwell#1 "which is still pumping today" and the various other wells on the section

I agree on the crafty side - finding any information on the engine has been pretty much nonexistence - guess dicks engine will be doing a lot of machine work if i cant find parts

Since its a two cycle the sideshaft is just going to operate the gov. & mag right? Just for show running purposes you don't have to have the gov. & magneto. You could run it with a simple hot tube ignition for the time being. Have you looked and an old ajax/superior to see how different the crosshead & rod is?

soaking the extra head found in the weeds next to the shed with piston in it - was planning on looking at some Ajax engines and modifying a cross head - although i would much rather find another engine like this one and either copy the cross head or use it in the best shape engine -

I doubt firecrackers are gonna do anything, even if the piston isn't stuck.....
I've used the grease gun several times to unstick a piston.
If you have the cyl head on it, stand the cyl up on its end, fill it full of diesel or any other cheap oil and get all the air out of the cyl that you can.
then thread your grease gun into the spark plug hole, the end of a grease gun is usually 1/8"npt thread. then just start pumping! the average grease gun pumps up to some where around 16,000psi Believe it or Not.
It if doesn't move right away pump it up and just let it sit, as it didn't get stuck over night, so sometimes it takes a few day /months. But its cheap and easy! although its very messy when it does come loose LOL

Well the main purpose was to get the head off since the studs were grown into the head - and also it did move the piston about 1/2 inch without cracking anything and now the cylinder is taking oil - I am sure that it will not take long to get it out now - I have located another cooper bessemer and planning on taking a trip to look at it -

Dude- Thanks for what you're doing. Saving big old iron is a LOT of work, but what we end up with is something that can be enjoyed by many for a long time.

Aside from some appreciation, I'm afraid I am no help with finding parts. This is the only cooper oil field engine I can ever remember seeing.

I will try and get out to get some measurements on the engine - the crank is probably 5 inches and the piston rod is probably 1.2-2 inches - cross head diameter is unknown and i will try to get an idea on it soon - thanks for your interest and any help would be greatly appreciated!!!
