Repacking auto bearings on "boat trailer bearings" is actually a typical maintenance challenge. Overlook this process and also you will be stranded beside the street when your wheel falls off! It really is not tough to repack the auto bearings over a little trailer with no brakes, as you don’t need to spine away the footwear or bleed the caliper.

Get rid of internal bearing. Clean both equally auto bearings, which should be lined and impregnated with dirty grease. If you wipe off as very much from the grease off with report towels prior to you use solvent it usually requires incredibly tiny solvent to have them clear. Inspect the rollers for any pits or scars, in the event you see any at all go invest in new auto bearings, which include new outer races. Take on the clean outdated auto bearings and seals with you, so the elements area can match them. I actually don’t like to reuse the seals, as they support to maintain the water out after you launch your boat.

Clear all of the aged grease, dust and water through the inside with the hub. Occasionally there is really a lot of grease in there, so I spoon it out very first, then wipe the remainder out with rags or paper towels. Clean the axle away too, and don’t forget to thoroughly clean the surface in which the brand new grease seal will experience. Meticulously inspect the “races” within the hub for pits or scars, it should be silky smooth. If not, you will need new auto bearings and races

 

Repack the bearingswith new grease. Basically, you placed a bit grease in your palm and mash or roll the bearing into it until eventually it’s gone in the nsk bearing. Placed additional on your palm and repeat until you can no longer get the grease to go from your palm to the auto bearings.

It is unlikely that the mileage will have any effect on a boat trailer bearings. The bearings on my tow vehicle have done 110K miles. It is the type of use. Dunked in water sometimes salt water maybe sometiimes when hot.have just serviced the koyo  bearings on my 4 wheel trailer this afternoon.

They don't do badly, the trailer goes into fresh water mainly, its a yacht so usually at least an hour between arriving and dunking, usually 3 or more if mast going up.
