Hello Everyone,

Just replaced the rod and main bearings
in my Ford NAA due to oil pump going
bad. Put new oil pump in and everything
runs well. Oil pressure at 42 PSI.
I was wondering if I should run the tractor
easy to gently run in the new bearings?

Thanks,
Tim, Ohio

Do you know why the pump failed?

Yes, the pump failed due to old age. The gears that generate the pressure were rounded on the
ends. The shaft was very loose. The new pump
had gears with nice, square ends and meshed together nicely. The new shaft had a bit of play,
but not like the older one. The shaft is sectional and joined together in the middle to
give it a bit on freedom of movement.

Hi Tim,

Run it.

If the clearances are set right, there is absolutely no "metal to metal" contact at the bearings as the surfaces are separated by at least a .001" layer of oil; therefore, nothing is rubbing and there is nothing to "break in".

If the clearances are 'not' set right.....it ain't a gonna matter anyway 'cause they will hammer themselves right back out no matter what you do in the driver's seat.

It isn't like breaking in a set of rings which "scrape" against the wall.

Two trains of thought. Some say to run it like you intend to use it, right out of the box. I always favored breaking it in easy, including changing oil in half the time as a normal duration until the first normal interval. Best thought? The parts that you installed? Did the manufacturer include any directions, or do they have a web-site? They would know best about their product, and may be very specific about what voids any warranty - many often do, and are.

Sounds like you've done a nice job with the bearings. For the first few hours, don't lug the engine (don't make it "snort"). After that it's ready for anything.
