Its a OEM Eagle trailer with zircs on the hub covers. Not Bearing Buddies, and has no spring plate or movable blue indicators.

How do you know when to stop pumping grease?

Re: Eagle Trailer w/Grease fittings on Hub Covers

I have an eagle trailer that had those things on OEM too. I didn't really like the fact that there was no spring to positively lube the bearings so when I had problems with a Zerk fitting on one, I just replaced both of them with Bearing Buddies a few months ago.

Before they were replaced though, I would put a couple of squirts (3-4) with a full sized grease gun in. I guess it worked OK because I never had a problem and the bearings and races looked in excellent shape when I got the trailer ready this spring. But I would usually take the caps off first to check the grease.

My Eagle has that configuration also.

I believe it is trade named "Speedy lube" or something similar to that and can be found on various trailers.

The zirk fitting you see is threaded into a hole drilled in the spindle that extends to behind the rear bearing, where it is cross drilled. This allows you to pump grease behind the back bearing, force it through the back bearing, through the front bearing, and out the front of the spindle (around the zirk fitting). This is the only way I know of to "repack" your bearings without removing them.

It is much better than bearing buddies IMHO. Bearing buddies keep positive pressure while underwater - IF you have them pumped up at the exact moment you drop the trailer in the water. BB's don't provide any way to change the grease that is in the spindle. If you aren't careful you can blow out the rear seal with BB's

As far as the positive pressure thing goes, in reality, the only thing that causes a vacuum is the contraction of hot air when the lake water cools the hot spindle. With the speedy lube system there is no air because you pump it all out and fill the spindle with grease. Grease is too heavy and dense to expand or contract enough to make a difference in this application.

My trailer is 12 years old and I've never had a bearing failure and only changed bearings once out of guilt.

There's a big difference between a zerk on the bearing cover and a zerk on the spindle .....

The "Spindle Lube" also known as "EZ Lube" and "Sure Lube" as well as a couple of other names typically has a bearing cover with a rubber plug in the center you remove to reach the grease zerk.

The OEM Eagle axles with zerks in the bearing caps are designed to be lubed as part of your preventive maintenance whenever you change your bellows, in other words every 33 or 34 years .... :D

This was an honest question. If you read the thread you would see that a subsequent poster added another twist...that being regarding a spindle not a cover. Maybe he was just trying to be helpful.

Your posts show you are never helpful. You seem to know a lot, but every once in awhile you show your lack of experience.

If you want to take things personal there is a procedure to do so. I have never made snide remarks about anything you posted. If you don't agree with me on one of my posts, just say so in that post. Posting crap when I ask a question shows you don't belong here.

*******s like you should be censored. I hope the moderator can see your hidden agenda.

You don't, so get rid of 'em. Replace those covers with Bearing Buddies ... ;)

Re: Eagle Trailer w/Grease fittings on Hub Covers

If it is in fact a Sure Lube hub, then relpacing the zerk/hub covers with bearing buddies will not do anything for you other than waste your money. It is not a pressurized system, thus spring loaded bearing buddies will not do you any good.

The Sure Lube hub has a hole on the back side of the torsion axle where the old grease is expelled as you pump new grease in.

I've had Sure Lube hubs on 2 trailers for 12 years, towed thousands of miles and have NEVER repacked or replaced a bearing, lost a seal or even pulled a hub for a bearing issue. Trailers have been dipped in fresh water as well as salt. Zero hub or bearing problems, period. The ONLY time I have pulled a hub in 12 years was for a brake caliper issue. Otherwise the hubs have NOT been touched other than giving them a couple of shots of grease a few times each year.

The minimal maintenance requirement means more time can be spent out on the water.

Wow, go out on your boat and take it easy for a while!

Sorry about the preventive maintenance humor - I doubt if anyone else even understood it! I just found it funny that in your previous posts you claimed to be anal about preventive maintenence but also seem to be proud that you haven't replaced your bellows in 26 years. No big deal, whatever makes you happy, it's your boat.

Please send me a copy of my agenda, or at least tell the moderators what it is so they can let me know. I didn't even know I had one! :confused:

Sorry, I interpreted "On" the hub cover as "In" the hub cover. Never heard of a zirk "on" the hub cover.. Sheeeeshh.... what a big deal over nothing....

The question was about a trailer. Nowhere was a bellows mentioned. Yours was merely a smart*** remark. Since you obviously didn't know the answer you should have kept your mouth shut.

Heck, its not even my trailer!

That's what I figured, MercGuy. Seemed pretty obvious to me that there was a communications breakdown. That's why I tried to clarify it in my original post #4.

Unfortunately, I apparently struck a nerve with my last sentence in that original post .....
