Thread: Trailer hub automatic bearing greaser

I see plenty over the years and now the boat trailer coming in have plastic shrunk stuff to hold these on and water proof.

I recently tried to use one to grease a troublesome slasher guide wheel -its a trailer bearing hub last 6 months,normally rust.

all that happend was it needed the inside seal to be removed to get the gease to the inner bearing.the grease pumped in came out through the bearing budy as it rotated.
my project was to be to drill the hub and fit a grease nipple to allow grease pumped in to the center-but im thinking now this will only pop out the lid and seal.

we are using a thick grease caltex liplex II[?].the type of plant we use requires lubrication in extream conditions.it doesnt wash out in water.

previously work use lubrication engineers products--these take too long to clean up prior to repairs,and a not next service person freindly--so i found out..

my dealership service work i prefer to use the old runny grease and do it often--im inclined to recomend the oil conversion-and check bearng tension a few times after service.if its good enough for trucks.

A long time ago when someone was paid to teach me to grease bearings(amoungst other things) the golden rule was two thirds grease, one third air.

and after lots and lots of trailer miles I havent seen anything to change that.
