How Long Will An Oilite Bushing Last?

[Deleted Member 4613]

Here's the theoretical answer:
Total hours predicted is: 456,000K divided by 7000 rpm x 60 = 1,085.7 hours.
This looks good if it is accurate. This is until it runs out of oil.

It has been reported that a common variator can run 2000 miles or more, on
an Oilite bushing here:

Sounds like a techometer/hour counter is needed to keep up with the hours. Or at least keep an odometer record.
