trailer bearings / tires

[Sean]

Alright I have never replaced/repact the bearings in a triler, I dont even know exactly were they are located ::), I know in the hub but have never seen them.
The boat/trailer is up on stands and the lugs on the tires are off/loosen (WOW was that hard, rusted and stuck!) I did a search on the site but couldnt find to much on the , "how To" of the bearings process, so any help, pointers, directions will be apreciated!!
Also, can you test tire pressure with the tire off the trailer?? ???

[macojoe]

easy part first, yes you can test the tire perrsure with tire off. *also always test while tire is cold, when hot they read higer!

Tires off trailer you see the center of the hub, take the cap off,
you will see a cotter pin, remove it,
some have a little cage thing next some don't, remove if so.
then you unscrew the nut, there will be a washer then the bearing. just pull the hub off and it will come right out.

Not filp over there is a seal on there, take off, don't worry about breaking it cause you are going to replace any way!!
After thats out you will see rear bearing, it will drop right out.

Now clean all with some degreaser and inspect, are they still nice and sliver looking? Put on fingers and turn, do they make noise? *Are there any rust or pitting?

If all is good then its time to repack, I bought this and it saves time and does a great job!! You can get any auto store.

you will also have to go to boaters world or a trailer place near you to get a new seal for the rear, some auto stores carry them also Napa is good with boat parts.


So now you have all your stuff clean, you have all your new parts, and you have greased your bearings, start with the rear (bigger bearing) lay a nice bead of grease in on the race (wear the bearing rests) push bearing on, then set seal square and lay a 2 x 4 on it, hit with hammer till seated, Careful not to ruin it!!

Now grease the axle and put hub on,
add some more grease,
grease the race and set bearing,
put washer,
then nut,
get nut snug NOT TIGHT,
put tire on,
now wiggle the tire, do you feel wiggle?? if so, turn nut till tire is just tight and STOP!

If tire is tight then losen till its just loose, the idea is to get it tight with out any drag when you spin it, to tight you will drag and burn the bearings out, to lose you will wobble and ruin bearings and lose the tire.

After you get the nut were you need to, add that cage thing if you have and then the cotter pin.

At this point you can tap the old cover on, or put some bearing buddys on, they are caps with a grease fitting in the middle so you can add grease to them when needed. *I would go with the bearing buddys if it was me.


Now if you removed the bearings and found themm to be damaged then ther is a whole different instruction!!

But we will save that till you see what you got.

MJ U R good! Billy Mac ;D

I bought my bearing buddys from MJ a few years back. When you add grease to a bearing buddy, only grease till you see the plunger move. If you overgrease, you'll blow out the rear seal.

MJ, perfect directions, what could go wrong ;D

Well I have these things/caps called, Reliabe Sure Lube. I assume they are the same as bearing buddies, but I cant find much info about them. They have the grease fitting and there site (minimal info) basicly states that I can just purge the greese that in there?? But that goes against what most say regardingthe bearing buddie.
Ever herd of these??
Thanbks!

here is there stat sheet:

Sure Lube Protection
When it comes to protection, nothing beats the patented power of Sure Lube. There are no springs, rubber plugs, or o-rings. Sure Lube uses a revolutionary double lip spring-loaded seal that ensures outer/inner bearing protection from corrosion, wear, and water entry. It's a time saver, too. Sure Lube lets you grease or repack bearings with just a hand grease gun and without disassembly. When only the best will do, use Sure Lube from Reliable.


Sure Lube Data Sheet
To ensure proper lubrication for the Reliable Sure Lube System, each unit should be lubricated with a high quality wheel bearing grease. This should be applied with a hand operated grease gun every three months, 1000 miles, or as use requires. Using 1½ - 2 ounces will give proper lubrication, and 5 - 7 ounces will completely exchange the grease throughout the wheel hub.

The grease seals that are used in the hubs equipped with the Sure Lube System must be a "Transcom" Brand of grease seal. These seals can be purchased direct from the factory. These seals should not be cross-referenced over to another brand of seal if they are being used in the Sure Lube System.

Sh!T, I just pulled out the greese port from the hub/cap thing and it looks like I just runied it...

[Crusher]

Sean I just did a search on yahoo. repacking boat trailer wheel bearings. all kinds of articles came up showing you how to do it. Crusher

[Sean]

Not as bad as I thought, once I broke of the cap, it looked just like MJ said it would ::)
I removed the hubs and they are sitting in the basement until after my girls _2 daughters and a wife) go to bed.
Crusher, thanks for the tip.
Thanks to all!!!
