Trailer wheel hub lubrication - Another way

Post by MoodyBlue »

I now own a Bayliner 2252 cruiser. Still have my Sonata 26.

But, this topic is about trailer hubs and bearings.

As part of checking, because I purchased the boat through Grays Online Auctions, I have no history of maintenance on the boat or trailer, so am fitting new bearings and seals so I have a benchmark.

The trailer for this Bayliner is an American built "Loadmaster" aluminium framed tandem trailer.

Of interest is the hub lubrication method which is grease, but applied to the inner bearing via a drilling in the axle, so new grease gets to push out old grease. I think it is a very good way of lubricatiing the bearings while ensuring new grease gets corrrectly circulated. I found a short video that better explains the system.

Looks a good system. I wonder how easy it is to get in Oz?

It would not be that hard to modify a typical axle.
Just need a lathe with a large bore through the head to accommodate the axle of one with a long bed.

Similar idea, but the grease travels in from the outer end displacing old grease out the drain port at the rear. This obviously requires a drop axle so you can drill in from behind.

We drilled 5mm holes concentric on the axle to behind the oil seal on both ends of my axle with an electric hand drill...
...and a guide tool machined on a more modest lathe which would not take 2.5m of axle!
