Hi Everyone!
In this series I'll be tearing down my 1957 Harley Davidson Flathead Engine with the hopes that everything will be usable enough to rebuild, clean, and reassembly into a working engine. In this episode I'll be showing ya'll how the to remove the cylinders off the engine.
This series is part of a larger series where I'm restoring my 1957 Harley Davidson Servicar. Check out those videos and follow along for more monkey wrenching fun!

You seem to know what you're doing as far as flathead disassembly goes, and the video is well done -but as a former helicopter mechanic watching you fumble with channelocks and a pipe wrench on an engine is soul crushing.

@@KevinWintersVA Can absolutely agree! Though I do have a very soft spot in my heart for vice grips (been with me since the beginning when I didn't even have a socket set). I hate not having the right sized box end to use (I've actually since made a wrench for those ginormous intake nuts). It isn't visible in the video but the only reason I own that specific pipe wrench is because its actually smooth jaws, so I basically use it like a giant crescent wrench.

Great restoration, it reminds me of my engine. Looked like it too. A lot of work, a lot of swearing and disappointment. And at the end the great joy when everything works. God bless the fladheads. Have fun restoring.👍✌

So my boy charlie. We where neighbors while he was filming many of these: unheated garage, Minneapolis, Minnesota winter. The motor slap is what we do in minnesota, make sure we can feel our extremities. The plumbing wrench is inexcusable though 😂

PS: The "Tatro Machine" channel does a lot with 45's if you want to see some interesting deviations from the norm. (Strokers, fancy head mods and whatnot.) But most of his stuff is already torn down and blasted, and it skips around a little.. So it was nice to see the level of detail and the nature of what you started with before anything was done to clean it up.

I like to spray the fasteners with penetrant a day before I dissassemble.
@theshop2064
@theshop2064 3 роки тому
This is always a hot topic, but I don't use penetrant on rusted fasteners. My go to is heat (unless the hardware is heat treated and that needs to be preserved), to expand the outer threads to de-bond it, or to expand the internal threads to crush the rust layer between the threads to make room. But I know everyone has their own special trick to remove fasteners so I don't judge.

Cringing in my seat. NEVER pry between the cylinders and the block. Invest in a dead blow composite hammer. NEVER yank up on the cylinders as was done. Use a piece of wood to gently tap down on the piston as you hold pressure up on the cylinder. I realize you were alone. I love that you were not afraid to tackle the job. Anyone that works in 10 degrees temp. has the gusto for the job!

Great video, bro. It is nice to see people into the older stuff. It has character a lot of contemporary motorcycles lack. I'm doing a chopper with a 45 G motor, myself. Detail on the pistons and cylinder bore would be interesting. I notice the pistons have that skirt oiling slot and the baffles are still installed. You don't see things like that anymore. It is an obsolete design now. Wonder how well it worked in application? Regards. Good luck.
@theshop2064
@theshop2064 3 роки тому
Interesting stuff indeed! The baffles in the crankcase (which I believe you’re referring to) are to aid in front cylinder lubrication (which is why you only see the machined into the front cylinder mating hole. The baffles cause a restriction and thus a low pressure as the piston goes up. This causes the oil misted air in the crankcase to travel up into the front cylinder and lubricant the cylinder wall. The rear cylinder gets all the “splash” lubrication so the baffles isn’t needed there. Now modern engines have oil squirters, etc. so you don’t see this kind of innovative thinking in design any more. Though it is more efficient to not have the baffles for pumping losses.... oh well
