Slow day here. Terrific video. He made it look easy assembling that engine.
I was wondering about his level of skill.
Is he just an assembler?
Most likely
How long would it take to become proficient at that job?
about a week. There are probably cheater cards, or more likely, the
parts are laid out in the sequence of assembly. This method of
assembly is known as modular production. In many cases it is lower
cost than assembly line production. sauer Sundstrand dumped a very
elaborate robotic parts storage and retrieval system, and lines, to
go to a modular high velocity system. The results were amazing.
Much faster turn around of orders. It allows building a production
run of one unit, rather than waiting until there were enough orders
to justify a line change. Assembly costs went way down. errors went
down quality went up.
They use a parts picker to assemble the parts needed for each
transmission, then the parts are staged for the assembly cell. A
cell might make the same thing all day for an OE order, or might make
a series of different transmissions for replacement orders. THey
also use a modification of this system to repair/rebuild
transmissions.
At AMG, they may specify the exact sizes from the parts suppliers,
(.001mm) or they have the parts picker matching pistons to bore
ahead of time. Modern machining allows all cyl to be the same within
.001mm and the same for pistons. Process control (SPC) and better
machines make this possible. It is the main reason why american
engines routinely go 300k miles , not 40k to 120k as in the 60s.
Does he need to be an auto mechanic to perform that job?
no
For example, would he need to have the knowledge and/or skill to
"mic up" a worn engine, determine how much to shave off the
crankshaft journals, determine what size bearing inserts would be
needed, etc.
no
Would he be able to perform this job using ordinary hand tools
(wrenches, sockets, etc.)?
Maybe. That would depend on the mechanical skills acquired off the job.
Just wondering.
