My buddy Dave Schumacher, Had to love his tests.
Didn't he quit yamaha in 2010?

[rodbolt17]

Dave has been gone a while.
I think he had some health issues a bit back.

but man I look a lot younger then.

passed that test back in march of 06.

passed the 4 stroke systems test about 10 am,by 10:15 we were seated for the master tech exam.
the only question the instructors would answer or help with was to spell your name.

100 questions 2 hrs 5 sections of 20 questions.
you could miss 6 total or 4 in any section.
miss 5 in any section and you failed.
that was the third test cycle of the MT program.
when the 2 min warning was sounded I closed my book,handed my test to Dave and said yall aint gonna let me work on Yamaha anymore.

I am not so sure I could have spelled my name at that point.

I think the first MT test I took was with Dave in 2008.
Tuff test, I took it 3 times. The last one I took PC was the
teacher. PC told me I missed it by 1, he wouldn't tell me
what question. I think it was about precision blend.
Long flight home.

Most of the test is hands on now, what I heard.

[rodbolt17]

PC is cool.
first time I met him he was teaching his first course ,drive train systems.

kid he partnered me with had never seen a trim unit.
the pair on the other table did something really really stupid.
they used compressed air to remove the memory piston from a v tilt cyl.
luckily I looked over about the time he was placing the blowgun nozzle into the cyl fitting.
I grabbed the kid and went mostly to the floor as the pistion and remaining fluid went by.
the stain is still on the classroom ceiling.

compressed air and hydraulics usually are a bad thing.

one of the auto shops I worked in some years back I saw a really bad hand injury.
guy was going to blow out the piston on a brake caliper.

good plan.
maybe not so good a plan to do it while holding it.
they took him to the ER with the piston mashing his hand and it had ****ed enough they could not push it back in at the shop.

he did not lose anything and I left about a month later. he still was not back.

I never understood why folks have so much trouble with precision blend.
it is a dirt simple system that will mostly trouble shoot itself . 4 switch's and a motor.

but PC says it still accounts for the most missed.

[boscoe99]

Dave retired. I seem to recall it was about the time when motor sales went into the toilet and they were looking for staff reductions.

His wonderful wife Marcie (worked at Bay Marine in Kennesaw) died at about that time I think. I felt terrible for Dave. Planning to go and do things with the wife in retirement and all of a sudden it ain't gonna happen.

[walleye1]

PC is a good guy, he was on the phones for a
while. Ya I have seen stupid crap in the class room.

When I was still working at a dealer ship our service rep
had not passed the big test, That was three years ago.
I had taken classes in WI and both PC and Dave would
be there the same time, Dave's boy was running a dealer
ship up there.

[boscoe99]

Yep, PBS is the major reason why the MT test is not passed. I advocated for Yamaha to build a simulator for folks to use but nothing ever came of it. Using a simulator right in front of you with all of the parts laid out made for a better understanding of the system. What did what, and when. And what did what when other stuff did what it did.

Scariest shop event I saw was when I worked in an airplane shop. Airplane wheels are bolted together. Tubes and tires are not slipped over a rim. An apprentice from Egypt of all places was unbolting the two wheel halves so the tube and tire could be replaced. Only problem was he forget to let the air out before hand. I don't know what bolts he had removed but when he had removed some or most of them, the load was too great for the rest. A big bang ensued and wheel parts rained down within the shop. He face was lily white instead of its normal brown hue. I think his pants were full of brown as well. Doing that has been known to kill people.

What always got me with pbs was the year and systm change
on how it operated. Back then we didn't see alot
of it to work on.

[rodbolt17]

all works mostly the same.
were some minor changes but not much.
Kennesaw has had a decent PBS simulator for some years now.

I must ask , seeing how I started this union meeting, what is this PBS business?

[rodbolt17]

it is Yamaha's acronym for Precision Blend .
a dirt simple oiling and oil transfer system that has been kicking technician butt in the US since 1984.

[99yam40]

acronyms are used to help our old brains keep sharp trying to figure out what they stand for
