Brian Whatcott Altus OK

1900 hours time for a overhaul? I am not a mechanic, but I thought one
of the reasons one would go with a diesel is for its reliability. If I
had a piece of equipment that operated 8 hrs a day, 1900 hours would
be about 237 days of
operation . Most of the machinery ( diesel powered ) at my work
operates 24 hrs a day. The equipment does get a service ( oil and
filter change) every 250 hrs of operation. What a huge liability if
they had to overhaul every 1900 hours.


It's pleasing to hear about long-life engines.
Used to be, recips used on light aircraft had a mandated overhaul time
- for most of them it was 2000 hours. Now its "on condition" like
jets....

Comparing auto engine lives:

You would like to make 150 thousand miles plus before tearing an auto
down (certainly we are making those numbers on a pair of econoboxes
we own.) If you averaged 40 mph long term - that would be 3750
hours.

Yes, but if the auto engine spent a very high percentage of it's life
at, say, 80% max hp, you wouldn't be getting anywhere near those hours.
Cruising along at 55 mph, the average auto engine is probably only
operating at around 10% load.
