Gee then it must be the government forcing manufacturers to make cars safer since the fatalities per passenger mile have dropped so precipitously.


You assume that the fall in fatalities per passenger mile are due solely
to the addition of various safety equipment. While it is a contributing
factor, there are other major factors. First, more passenger miles are
being driven on limited access freeways where fatality rates per mile
are far lower. Second, increased traffic congestion has reduced average
speeds.

But John's statement is also not quite accurate. While it's true that
the industry has worked to decontent vehicles to save money, at the same
time they've added various safety feature which don't cost much to add
since it's just some inexpensive sensors and software. Traction control
basically costs nothing once a vehicle has wheel speed sensor for ABS.
Collision avoidance, lane departure warning, back up cameras, and TPMS
have a very low added cost. Meanwhile, they've saved a lot by moving to
2.5MPH bumpers from 5MPH bumpers (Reagan's fault), eliminating high cost
items like vent windows, rain gutters, balance shafts, weatherproofing,
and one thing I just noticed, dual horns (high/low). Also really
annoying, on the last two vehicles we bought, was the absences of a way
to prevent the trunk from being opened from inside the vehicle.

The manufacturers have realized that safety sells, so they don't want to
eliminate parts that help them do better in the crash testing, and they
compete for the most airbags.

O
John, my wife's older Keo tells her if a tire is low. Is that by government edict?


Um... yes, it is.

My car warns me if my gas is getting low so that I won't run out on the freeway. Was that a government edict? We are getting small sedans not only swerving in front of tractor trailers but being struck so hard that they are doing multiple roll-overs with the cars totally unrecognizable afterwards and NO INJURIES to the passengers. What are the government edicts? You have to wear your seatbelts.


There's a lot of these rules that you don't seem to know about. Maybe
you should at least hit Wikipedia before posting.
https://en.wikipedia.org/wiki/Federa...fety_Standards

If you don't know the business don't make your comments as you usually do. It is almost entirely the automotive industry that is improving auto safety. This is especially important as vehicles become less and less metal. On my smashed up 1999 Ford it appears that the only steel on it is the frame which is bent so badly that one wheel is so high that it isn't touching the ground. There is no damage at all in the passenger compartment.


That's probably a result of the crash impact standards. You know, the
things they do with the crash test dummies inside the cars? Regulation
FMVSS No. 201

Doug - those were not plastic gears. It was a COATING that could peel off and cause problems. Mostly they plugged the oil system.

I'd be careful blaming jumped timing on the coating. Tearing through the gears drag racing would beat the timing gears to death and this normally caused the timing gear failures. I've seen a tooth broken off and the jackass still driving it with Lord only knows how the gears would work.


Tom shut yer mouth willya. I towed the old family car home myself from skool, and changed the timing chain and gears; the teeth were nylon and stripped off, and the chain had hopped and the timing marks on the gears were no longer aligned, but off by one tooth. Which is why all the backfiring and spasms when it wouldn't start.

... Given Vietnam's history
since, say the 1850's, the average Vietnamese is probably as happy
under the present government as they were under previous regimes.



Having met a lot of Vietnamese people, including people where not all
relatives made it out, I do not think this is true. I also had relatives
who had to live in a former communist country. They would have been shot
if they had tried to leave. Nobody will ever tell me there is nothing
wrong with communism.


As a general statement, those who escaped from Vietnam were people
with a certain amount of money. Call them the middle class.



Not the ones I met. They didn't have much more than the shirt on their
backs and most didn't own real estate over there or had much in terms of
other wealth. A simple bicycle was already considered a luxury.


... Certainly
Thai pirates were active in robbing them and in cases where the
Vietnamese were subsequently rescued they all complained of being
robbed of money, and from personal knowledge an escape boat that
approached a drilling platform in Malaysian waters offered to pay for
food and water and a later boat that landed on Karimun Island in the
Java Sea offered to pay for food and water using gold.

But the so called middle class is a minority in Vietnam, The Boston
Consulting Group estimates that the "middle class" may include as much
as 1/3rd of the Vietnamese people by 2020.

It was the remainder, the "peasants" that I was referring to when I
said "the average". Perhaps I should change that to "the majority".


I was referring to the same group. Simple workers. They fled because of
brutal oppression. Here in the US they realized how much of a
perspective they can have, learning new stuff such as electronics that
would have remained a complete illusion in Vietnam.


As for the blissful life under the U.S. supported "democratically
elected government, well religious freedom didn't really exist, to the
extent that Buddhist monks burned themselves in protest. Of course
that was right and proper for the Christians (some 6 million
Catholics) to persecute the heathen Buddhists ( some 12 million).


A lot of bad things happened half a century or more ago, sometimes in
the name of "Western values" or 100+ years ago even Christian missionary
"work" (and I am saying that as a practicing Lutheran). However, things
got better, much better. In communism they didn't.


By the way, the number of "boat people" who escaped Vietnam and
arrived in a foreign country amounted to about 800,000, call it a
million and an additional 1,000,000 escaped by other means for a total
of 2,000,000 during the 20 year period from 1975 - 95. Or roughly
100,000 annually.

From a nation with an average population of about 61.5 million during
the same period.


That qualifies as mass exodus, especially considering the untold
millions who did not succeed or didn't dare. Plus those snatched and
sent to "re-eduction camps" a.k.a gulag.

anvil as usual. To my utter amazement it doesn't show any measurable
stretch after over 2000mi and sometimes I really put the coals on
because of our hills. Even the old Wippermann chains could not rival
that. I am very religious about chain cleaning and lube though.

The old 5-6-7 speed Sachs chains wore out three days after the bike
was junked.


The Sedis (later Sachs-Sedis) material and Delta hardening process was
not only exceptional but unsurpassed down to today except for possibly
Record chains. That ended with SRAM.


Why is that? In the automotive world such an advance in technology is
kept and further developed, not rescinded and chucked back into the dust
bin. Well, usually.

For example, transmissions nowadays typically last the whole lifetime of
a car. 20+ years for us on two vehicles so far, for everything. Vehicle
owners would have a hissy fit if they had to swap out a chain every 5000
miles.

I think that you are confusing reality with your own fantasies. In
years past I have worked with two engineers who had worked in the
automobile industry. They both said the same thing, that the major
effort in the motor industry was to "make it cheaper". One of them
described a cash for suggestion program that Ford (I believe) had for
a time and commented that when you made a million cars the removal of
one sheet metal screw in the firewall was of interest.


You've got to do your research first and then buy the right brand and
type of car. Which I always did except for my first car after getting
the degree (learned that lessen very fast).


And what research is that?



Reliability statistics from large auto clubs (those guys truly know),
then in the 90's here in the US "Edmund's", and talk to car mechanics
(those also truly know what's good and what isn't). Then research how
it's built. H-frame truck chassis (good) or unibody (not so great), and
so on. Most of all, look. The sales agent's jaw dropped because I was
his first customer ever who wanted to crawl underneath the vehicle
before signing on the dotted line. Which made me wonder why none of the
other hundreds of customers did. I liked what I saw there as well as in
the engine compartment, and signed the deal. Never regretted it. Number
of defects in over 20 years and close to 80k miles: Zero. Not even a
light bulb filament has failed.


... I do not remember what make of automobile
you mentioned but I do remember thinking that it was a low end model,
whatever it was.



1997 model Mitsubishi Montero Sport, 2WD, 4-cylinder engine. Built on
the MightMax truck chassis which was important to me.


... Is that research?



What I did? Yes, it was.



... I just looked up "best SUV" and two
out of the three best SUV's (for 2017) were Honda so I'd guess that
you must be driving a Honda. The third choice was a Ford.


Mine is model year 1997.


As for a chain drive lasting 5,000 miles, it is perfectly feasible to
build a chain drive that will last more then 5,000 miles. Of course it
will cost more and be rather large and ugly and will, of course be
heavier then a current systems, but it can be built.... if anyone will
buy it.

What's his Face... the guy that lives in the low rent district of the
Irish Republic, did that a few years back and described how it was
done in loving detail.

I haven't bought a new chain in some time but I did see a 9 speed
chain with a price tag on it recently and it was 500 baht. In Usian
money that would be about US$15.07.

Are you telling me that people that sprint around on 1000+ dollar
bicycles worry about a bicycle chain that costs so little money? 1.5%
of the cost of the bike?



No, I am talking about people like me who also use bicycles for
transportation and not just for sports.


I'm not so sure. You talk a lot about how much you ride a bicycle and
complain loudly about chain wear while James documents his rides - I
believe that he is in the 10,000 Mile?Km? region per year, and doesn't
seem to mention chain wear hardly at all.


Probably depends on weight, hills, dust and so on. I am comparing apples
to apples because it roughly the same turf I used my SUV on. Past tense
because last tax year was the first where I dipped well below 1k miles
for my car.


It would seem logical to assume that you must be riding somewhere in
the neighborhood of what? 15,000 miles a year? If you never take a
holiday that is ~40 miles every day.



Only 4000mi, which will increase once I can fully retire. That hope was
kind of dashed in a phone discussion this morning, for now.

Simple - the motor runs quieter, and consumers buy it more readily.
Hence we saw plastic teeth on timing gears.


And they make that last 100,000mi before a PM swap. That's what it says

You really are the master of premature conclusion. If you had followed
carefully I own none of those vehicles and never will. There are reasons
why not.

Mine has toothed belts with fibers in them and metal gears. All of it
including the toothed belts looked like new when changed. The only
reason I changed them before 100k miles was reached was the vehicle age
of 15 years. Turned out I could have left them in way longer.

Same with the tires BTW. They had 60k miles, still half the tread but
were well past 10 years. Looked good buy common recommendations state
that means it's time to buy new tires. Try _that_ with a bicycle tire.

The smaller Ford V6 uses rubber timing belts and they insist that you
absolutely MUST replace them on 50,000 mile intervals or bye-bye
motor. GMC apparently has a V8 that way. My stepdaughter's SUV broke
a belt and exploded the motor - the mechanic told her not to replace
the motor because the new one would do exactly the same thing.

My Ford has the larger V6 with a steel timing belt and they go just
short of forever. These cars are advertised 5 years old and with
200,000 miles on them. People actually commute from Sacramento to San
Francisco!

Here's one with almost 250,000 miles on it:
https://sfbay.craigslist.org/eby/cto...266166468.html

In the '60's you'd be LUCKY to get a motor to last 100,000 miles.


Unless you bought the right car. My Citroen 2CV from 1969 rusted out
from underneath me around 1985 but the engine with 90k miles on it was
still purring and had no oil consumption to speak of. It was carefully
removed from the car at the junk yard and sold for a nice sum of money
to a Norwegian. Meaning I also got good money for a car that would
otherwise have incurred a waste disposal fee.

The only change versus stock was that I replaced many seals with
hand-sawn and polished copper versions. Afterwards it idled as smoothly
as a brand-new Harley, patoomph .. patoomph .. patoomph. The junk yard
owner couldn't believe it. "I only ever saw that stuff on a Bentley".

The recommended timing belt change interval is very conservative. I've
had it done on my SUV at 100K and while the belt did not look new when
it came out, it was clear that it would have gone far longer without
breaking. There are several advantages to timing belts versus timing
chains, especially on engines where a long chain or belt is needed. A
timing chain needs to have a system to keep it oiled. Chains stretch
more than a kevlar reinforced neoprene belt. Chains are noisier. Chains
are expensive to replace and contrary to what some people believe, they
do NOT last "forever" just because there is no scheduled replacement
interval.


The best was my Citroen 2CV, the 16-horse version. Two meshed metal
gears (no belt, no chain). It also had no distributor and no external
belts to drive anything. The generator sat directly on the shaft and the
propeller to cool the air-cooled engine sat in front of that on the same
shaft.

It is done for both. However, most of all for coming generations because

I found this an EXTREMELY odd answer from Doug. I actually think far more of my step-children than I do of myself. Making the world a better and safer place for them is the object of government.

What possibly could make ANYONE that is sane think any differently?

today except for possibly Record chains. That ended with
SRAM.


Why is that? In the automotive world such an advance in
technology is kept and further developed, not rescinded and
chucked back into the dust bin. Well, usually.

Simple - the motor runs quieter, and consumers buy it more
readily. Hence we saw plastic teeth on timing gears.

In this case, the non-hardened chains make less noise, 'cuz the
edges go 'ting' less, and consumers perceive this as better
shifting. ;-)

Doug, some woman came around the corner, dropped her water bottle
(so she says while clutching her smartphone to her breast) fished
around for it and ran into the back of my parked car turning it
into a pile of scrape metal and plastic. Looking for replacements
I find 5 year old cars with 200,000 miles on the original motors
and not only said to be running smoothly but still getting good
mileage. That isn't being done with plastic gears. I picked up a
2007 with 50,000 miles on it and expect it to last my lifetime
with only normal maintenance.


I'm talking about the automotive scene in the 1970s, Tom.


Doug, what cars used plastic gears in the '70's? Perhaps there were
but at that time I was buying pretty good cars like Mustangs and
Camaros with big engines in them. Not to drive fast so much as to get
on the freeway ahead of people purposely trying to cut you off.


Volvo, but with plastic gears there is usually no chain or belt involved:

They could go pretty fast, too, especially after being souped up:

A friend's parents had a Volvo with the plastic gear. He said when that
failed it was replaced with a metal one by the dealer repair shop and
afterwards the engine was noisier.

The chain slips seldom when speeding up; can this break the chain? or do I have to line up the back sprockets? Iván C. Filpo Techniques 4 July 20th 06 04:44 PM
