Adding your own Zerk fitting to avoid the previous steps above:
i.
You can add your own zerk fitting to the front of your hub by adding a Bearing Buddy
®
Protector.
ii.
Look for Model# 1980A and follow the manufactures instructions for use.
Type of grease to use:
Automotive bearing grease is OK in a pinch, marine wheel-bearing grease is better, and
synthetic marine-wheel bearing grease is best. Best advice: Use a high-quality synthetic marine
grease that’s water resistant, and do the best job possible cleaning out the old grease when
repacking. Don’t mix old and new greases if possible, and record what grease you’re using,
so you know what to apply when your bearings need a shot of the slippery stuff.

1.
Remove dust cap, cotter pin, crown nut, washer. Pull hub off spindle.
2.
Use a hammer and a mild steel bar to drive out old inner cups.
3.
Use a solvent such as kerosene to clean the hub, nut, washer and spindle. All dirt and
old grease must be removed.
4.
Inspect inside the hub where the cups seat and the spindle for scoring, pitting, bending,
dents, thread or other damage. Pay close attention to the raised rear surface of the
spindle where the grease seal grips. If it is scored or pitted the grease seal may leak.
5.
File off nicks or burrs using a fine file or emory cloth, then wipe away any filings, then
re-clean with solvent.
6.
Coat the spindle and the inside of the hub lightly with grease.
7.
Use the mild steel bar to drive the new cups in to the hub until they are solidly seated.
Do not damage the cup surfaces.
8.
Pack both bearings with grease forcing grease inside the cage in-between all the rollers
starting at the large end until grease shows at the small end.
9.
Install the packed rear bearing in the hub.
