[SPAM] Re: A Bearing Tip - Boca Bearing Newsletter

[Bob Pastorello]

According to Boca, anyway, Yes, as it permits more fuel/oil in the lower 
crankshaft area, the conrod, etc.  I can't really say one is right or not, 
but I've removed the seals on my OS 1.60 because I didn't like the "dry" 
look of the counterweight when removing the backplate.  Now, having the 
seals gone, there is quite a bit more oil back in there, and I reason that 
that means there is better lubrication on the stuff.

But - no evidence, just observation.

Bob, So using an OS 140 EFI bearing, is it advisable to remove the seals?

Since I use theirs, I get this e-newsletter.  This month's tip;
<<If your Front engine bearing has two rubber seals you should not remove 
them. These bearings have their own grease and can help stop oil leaks. If 
your bearing has two shields, we recommend you remove one of them. For 
instructions on removing your shields take a look at this Help Section.

Your Rear engine bearing should be open on both sides to allow as much fuel 
as possible to pass through and act as a lubricant. You may however want 
leave one shield on in the rear which would help to protect the rest of the 
engine from any foreign matter getting through. This should not be done with 
one seal. If you find your engine is stingy in getting fuel to the rear, you 
should definitely leave the bearing open.
In our next issue of the Boca Bearings Tips & Advice Newsletter we will show 
you how to remove your bearing shields. >>
Note - if you open your crankcase, using sealed bearings, and the crankshaft 
counterweight it dry-looking, or the lower part of the bearing isn't pooling 
oil, you may think about removing the seals.  I do, for this reason.
