Is there any need for Grease inside the bearing housing where the bearings sit?? I guess grease might make it easier to tap the bearings into place, but could make them less secure in the housing??
Also, should I put grease on the sides of the bearings themselves? I have heard most bearing housings have a small hole to let out water that gets in, but this Zanussi doesn’t seem to have them.
Also, when I replace the pulley bolt is it necessary to use loctite thread sealant or some other glue, or does it matter at all??
