Our Sea Scouts have been busy refurbing our "new to us" RIB. We now need to change the bearings on the trailer (ominous grumbling sounds) and have a chap that can do it - but he can't get to the boat to identify what bearings we need! Is there any way to do this from photos?
try trailer man on here for advise, try to find out make & model of trailer. when i did mine i stripped one down and measured up spoke to mersea trailers job done.
good luck
Have a look and see if there is a makers name on the axle such as Meredith and Eyre etc. You might also be able to identify the hubs from the style of the back plate and narrow down what bearings it uses. One or two of the bearings websites have some guides that help. This kind of thing may help.
There will be a number etched on the bearing. You need to pop the black plastic cap off, remove split pin, undo castle nut remove washer. You now see the front face of bearing. Clean it off and look for a code.
That said ... Replace the hub. I'd buy three. Keep one as a spare for the roadside..
if you strip the bearings from the hub and clean them of, you will find a makers name and a number on the outer race, and usualy just a number on the inner race. Thats what you require for replacement.
Try to make up one good spare unit out of what you strip off and keep it in the spares box, or......make up a mount that carries the spare hub bolted to the trailer, this in turn holds the spare wheel.
