Any ideas?

Anyone care to hazard a guess at the manufacturer of these hubs? I'm thinking maybe Alko but could easily be wrong. They're on an R.S.A Satellite 2500kg twin axle roller coaster trailer.

Thoughts appreciated.

Thanks.

Reckon you're right with Alko. The fins on the drums and the dust cap fitting inside the boss make it look like it. IIRC Satellite were/are a French manufacturer - dabbled with selling their car transporters about a decade ago - so that would probably fit with the Alko running gear.

Have a look on the inside rim of the backplate - it should have a four digit number stamped on it, something like '2031' or '2360' plus 'ALKO' if your lucky

Best guess without having a look myself, but I think you're right.

Couldn't find anything on the inside rim of the backplate but here are some more photos of the hub and a collection of numbers and letters I found on the outboard side of the drop arms.

Any clearer now?

Oooh, the plot thickens!

Reckon they're either:

GKN-FAD drums. Probably 200x50 brake shoes. Or...

Alko drums with Alko internals. Probably 2051.

Does the dust cap have anything on it? Looks like it might, but I can't tell from the piccys!

Or are there any plates riveted to the centre of the axle?

Ah that's interesting, the hub caps have what I believe is "GSA" written on them, but will check for sure tomorrow.

The only thing on the axle is this sticker.

Thanks for your ongoing help Trailer Guy, it's much appreciated!

Having done some more research it turns out that R.S.A (manufacturer of the trailer in question) are in partnership with GKN-FAD. There's some info about the partnership on R.S.A's website and some stuff about how GKN provide all the running gear for R.S.A's trailers. So it would make complete sense for the hubs in question to be manufactured by GKN-FAD.

Only problem now is finding some info on GKN, which is easier said than done!

Hi Jonny

Have you got a chassis plate on the front of the trailer? If you've got a trailer type I reckon I'll be able to narrow it down for you.

Reckon if it's GKN they'll be Knott 200x50 brakes. Especially as it's 1500kg.

Hi mate,

Have attached a photo of the plate that's on the front of the trailer.

Took a hub apart this evening. These photos were taken of the hub on the axle that performed OK on the drive home last week. The other axle got very warm and I expect is in a worse condition. In essence, I think those brakes look completely shot. There was very little movement when I tried to "wiggle" them and it's almost as if they're rusted to the backplate. But I can see that we're looking at some roller taper bearings. How do you grease these, there are no grease nipples?

I'm confused, GKN make running gear but use Knott equipment?? What does the 200x50 relate to? Hub face measurement?

Thanks a lot for your help mate.
Jonny.

Hi Jonny

Welcome to my world! Rusty bits if metal and seized components

Right, going by your pics of the chassis plate and brakes, I reckon you've got a Satellite model 252S. Have a shoofty at this and see if it looks familiar:

RSA Trailers spare parts : Launching types 212 342/S

And here's a break-down of the braking components:

RSA Trailers spare parts : SAV moyeux et freins GKN-FAD

Trust this is the sort of info you are after?

Agreed, your brakes are buggered, but the bearings don't look too bad. To clean them and grease them isn't too difficult. Pull them out (to get that back one out you'll need to prise that seal off). Clean the old grease out of the hub, degrease the bearings, then re-pack with grease and re-install.

Have a look at this previous link - scroll down to the 'how to change a set of taper roller bearings' post and that'll have pics on how to pack a set of bearings with grease.

Trailer info

Hope this is the sort of info you're after. All the best.
