Bearing Replacement

Post by Tim Ander » Sun, 06 Jun 1999 04:00:00



I have an asp .40 that the bearings needed replacement on. I purchased
new bearings from Boca to install. The new bearings had shields on both
sides on both the front and back bearing. The factory bearings I removed
from the engine had no shields on the back bearing and only one shield
on the front which faced toward the prop. Should I remove the new
shields to match the old bearings or should I leave them on as from the
factory? I am a bit confused. I know I dont want air sucking in thru the
prop, but can the bearings get oil with all the shields in place? Any
help would be greatly appreciated. Thanks.

Do not remove any of the shields, they are much higher quality bearings
than the one's your ASP came with, they will work perfectly well as is.

When I got bearings from Boca, they told me to remove the sheilds to match
whatever I removed from the engine.

        Remove the shields on the rear and the inner one on the front.
This is a common practice.  Bearings run in oil mist (the rear) and
oil have a higher rpm rating than those run in factory grease.  The
shields will not help you any in this circumstance.  They are not
seals.  Some front bearing applications use no shield at all, even
next to the drive hub (Webra, for instance).  Oil from the case is
pushed to the front bearing and lubricates it.  The seal is a factor
of the fit of the crank in the case.  In cases where leakage out the
front is excessive a sealed bearing may be of help.  In general they
are not used.  Seals are different from shields and can create a
slight running drag.  Follow Boca's instructions for removing the
shields.

I also remember being instructed to remove shields to match the old ones.
