Should I remove the shields or seals from my engine bearings?
If your Front 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, see the next section)
Rear 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 foriegn 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.
