Broken valves and broken dreams
It should be noted that BlueBird recommended and I quote; Keep it around 2000
rpm. The recommendation is for the 3208. Cat calls 2400 rpm in marine
applications, "continuous cruise speed".
Some people think it's wise to check valve adjustment every 50k miles, some
think that's too much. I check it more often as I fear broken parts and I DO
NOT EVER take short cuts with my vehicles of any kind.
However, ignorance is bliss for most folks and occasionally the bite in the butt
from reality hurts.
Weak valve springs is the most common cause of valve failure, springs can lose
tension in storage. At rest, some valves are open at max lift and some are
closed. Those that are open can take a set and lose closing strength, this
allows the valve to bounce in operation, compound the problem by running
2700/2800 rpm and some times stuff breaks.
Watch that valve lash and check the valve spring tension regularly, other wise,
keep your fingers crossed. Ain't diesels fun?

Just one nagging question and that concerns the chart on the Vintage
Bird site! it states that at 2000 RPM' at 3208 n/a engine in a F/C
unit speed will be 48 MPH. Now lets get real about keeping it at 2000
RPM's and going down a freeway. Do you think when these coaches came
out that the Bluebird Corporation stated in there factory manuals
that there motor coaches would last allot longer if they were only
driven under 50 MPH? I might be different than most drivers but I try
to keep my speed at 55 but not 48 mph on the freeway. Does anyone
have a drivers manual for one of these old units? it would be
interesting to check it out and see what corp. said in those days.

Hmm, 2200 is 55 in your "vehicle", sounds like "around" 2 grand to me. Mebbe

Broken valves and broken dreams
The CAT operators manual for my coach says nothing about optimal rpm.
It says do not run it above the rated rpm on the engine plate
(2800rpm for a 210hp na). It says it can be run at full load between
the rated rpm and 1900rpm (for NA) It does say DO NOT run it at full
load under 1900rpm (for short periods, down to 1400 rpm's) for an NA
or not below 1400rpm for a turbo. If they thought there was an
optimal rpm, why not include it within all those limits?

Broken valves and broken dreams
Yo, Kerry, you have a rig that's 24 freekin' years old, you want to run that
tired old tank at 100%, be my guest.
You and Jon should talk to Ralph F about the way things are. He could bring
some interesting tidbits to your attention. I have turned wrenches
professionally for 30 years and I can deal with Cat mechanics as equals. Most
of the people in vehicle service in the Milwaukee metro area know who I am.
That said, I have NEVER talked to a competent Cat man who thinks it's OK to run
a 'throwaway' against the governor. You guys who know better have at it. Hope
it don't blow up when you loan it out to some "tourist".

I asked a simple question. I said nothing about how I would run my
vehicle. Do you know why CAT did not put optimal rpm's in their manual?
I don't see what any of this has to do with who drives my vehicles.

Broken valves and broken dreams
Caterpillar had weak valve springs in the early 80'S, we replaced thousands in
truck engines, there were other applications that used the same spring and they
gave no trouble if the engine was not in a truck.
as far as rpms we had 3208's in several applications, med duty trucks, scrapers,
and irragation engines, and excavators. the irragation engines ran at full load
for weeks on end sometimes when their was a drought, in an excavator you fire it
up ,warm it up, move to full throttle and dig holes and ditchs all day. the
medium duty trucksi think in those days the speed limit was 55MPH but not sure.
strrong engine but keep your valves adjusted.

just to see what kind of comments I would get about that chart. I
wish I had enough money to put in a new set of gears for the rear end
so I could keep up with today's traffic but cost wise its just not
worth it. And like I said before when I'm out on the road its not
how fast I get there but just the enjoyment of the rig and its being
built like a tank. Wanderlodges forever!!!!!!!!!!!!!!!!!!!!!!
