Marine wheel bearings?
Submitted by Adam Gallash on Mon, 2011-02-21 12:35
Hi Gang,
I'm in the last process of buying the boat and its in for inspection at a trailer joint. The guy has given me the option to check the current bearings (changed a year ago) and just re-grease them or if I want the owner will pay for new marine wheel bearings (apparently greaseless?) which I have no idea about and will cost about $370 (his expense). Can anyone enlighten me regarding these marine bearings and if they would be good for long distances, hot conditions etc?
Cheers,
Adam

The only greaseless system
The only greaseless system I`ve heard about is the durahub one. Like bearing buddies sortoff but you run gear oil in them instead of grease. Good idea but if a rear seal goes or you lose a cap( happened to me twice ) then you lose all the oil and the bearing fries pretty quickly. Ive still got the durahub caps but grease the bearings as normal.

5.65
The 5.65 Haines Center Console with the 115hp 4stroke, will put up some pics once I get them. Bit of a risk buying it sight unseen, but you only live once.
So it might be just better sticking with the normal wheel bearings then.. Still waiting for the trailer guy to call me back to get the exact story.

Good chance of it. :) First one wasn't luck though, it was obvious even from the photos that it was a quality boat that had been looked after.

stick with bearings
and a protective cap IMO. Much easier to replace a bearing on the side of the road than a durahub if the worst happens......

Yep normal bearings
And normal caps bugger the bearing buddies too expensive if you lose one, not worth the money imo just check and grease your bearings yearly and you wont have any dramas

Dust caps
Instead of bearing buddies just tap a thread in to the dust cap and screw a grease nipple in. Does exactly the same job as the buddy. Give it a squirt or two every couple of months to keep the pressure on.

standard
Adam , keep it as simple and easy as possible , standard bearing , with or with out bearing buddies , you only need to have a minor problem when travelling on the open road and how many road houses or country towns keep Durahub parts , where as most travellers carry a spare standard bearing or something that will get you by IMO. Good luck with the new rig

Whatever the bearings it can
Whatever the bearings it can also pay when you arrive at the ramp to let the bearings cool for 5 min (take the time to check/set up the boat for launching) particularly if you've had a reasonable drive to get there and heated things up. If you back the bearings (with hot grease) into the water the grease suddenly cools/shrinks and can suck water into them which leads to problems down the track.
Ps I have bearing buddies and have had not any trouble - I check them before my 2,000km round trip - but agreed on the side of the road normal bearings are easier to work with or replace/get parts.
Cheers

Bearing Buddies
I prefer bearing buddies as I can visually check the grease level by looking at the bearing buddy.Also you cannot overload the grease as you can watch the plate inside the bearing buddy move to show full, so you don't blow the seal at the back of the hub. Also was advised you not fill with grease and allow some movement. Bearing buddy allows this with when trailer reversed into the water if they a bit warm still. On long trips you can check the bearings visually each time you stop. Also easy to maintain yourself.
