Engine Assembly at factory

[Thepen]

I know this isn't a Honda engine, but I'm assuming our engines got put together the same way. Its funny how we're all tip-toe'y about torque specs, and they just impact everything lol

The part where they pressurize the crank case and submerge the engine to check for leaks is quite surprising as well.

At 3:30 he set the valves in less than 10 seconds without a feeler gauge. Sometimes we Americans really over-think this stuff.

Honda's assembly looks much more efficient, precise, and safe in Japan, probably also in Thailand. This would be more due to the brand, Honda, rather than the region they're being produced in.

I like how they bought them all matching t-shirts for camera day.

yeah that's a knockoff motor, they don't care nearly as much. having been in a quite a few engine assembly plants over the years, there is definitely a difference from cheap throwaway items and companies that actually give a shit about quality. I worked for a company that actually sold, setup, installed and provided strategies for assembly lines, so I saw this at the ground level up. And no, it wasn't a US based company.
Its neat though. Thats for sure.

Based on the name of the video and some details, I'm pretty sure this is the engine for a Metro MR70. It has a reputation as being a very durable bike ("the most durable bike of Pakistan").

I manufactured knives for industrial applications for a couple decades and I just want to throw in something, please consider that the second sentence has no logical relation to the first.
Regarding country of origin: since we sold knives we had to purchase oddball or types that we didn't make. Huge differences in quality between 2 companies in the same nation. Country doesn't matter, company does.
And regarding over-thinking: After you've done something so long you KNOW certain things. I could consistently pick up 10 knives out of a group because I knew what 10 of this particular knife felt like. I'd done it so many times that a group of 9 or 11 was obvious.
These assemblers know how far from snug to turn a bolt to get a gap that's good enough and maybe dead on. If you know the thread pitch you can divide a full rotation into useful measurements so 1/4 turn equals .xxx" or whatever.
(edit: lol, I'm describing a micrometer. He's using the fasteners as a coarse-thread mic!)
For those of us who don't put together motors non-stop all day long, whether we're American, African, or Pakistani, a feeler gauge is the best bet.
I hope this doesn't sound di*kish, I'm just old.

It may be IP so we'll never get it, but I'd LOVE to watch a video from one of these assemblers talking about all their tricks!

Exactly! You only need a feeler gauge once to set the gap. Before you "snug it", turn the bolt in and count the rotations until it touches. Back it back out, double check if you like, and snug it. How many guys actually take the time to do that. If you do this once (and remember) you can set the valves every time without a feeler gauge. Should take you longer to get the covers off and find TDC than to set the valve clearance. I've never had to ride around with a valve clearance gauge before but I get the impression that certain things on this bike get loose/worn out on the road fairly often and you may need to pull over and address it. (Stock chain, valves, sparkplug.)

Oil change and chain clean/lube should take 5 minutes. Clean/lube the chain while the oil is draining, wipe off your gold plug, button it up and fill it with .7 qt of your favorite oil (if it's pre-measured, it will go even faster). I'll change the oil every 1000 miles just because it's so cheap and easy.

Adjust the clutch? 15 seconds, tops. Will take you longer to find the wrench and screwdriver.

Change out the clutch pack? Laughably easy after you've seen it once.

The more I fiddle with this thing the more I realize how unbelievably simple it is to work on. I refuse to over-think it like I have in the past.

being proficient means you don't skimp on measurements. it also means you can do it quickly, but correctly. usually there's a jig or tool to set stuff, not 'whatever' by hand. Like said, ive been in modern plants and have seen 1st world mfg on powertrains 1st hand. just 'winging it' is why I will pass on buying stuff like this.
