Retro fitting bearing savers

I am considering fitting bearing savers to my twin axle it's an Admiral trailer with peak axles, what I want to know is when you take the drum off are the B savers easy to get off.

See my post here bearings. They are tricky if you don't use the right technique.

You take them off before pulling the drum, as they block access to the castellated nut.

Usually I use a mallet or hammer, and whack the bearing saver from 4 points around the diameter, which walks them out of the bore. Some are more stubborn than others (which is a good thing, as they are less likely to go solo rolling down the road.)

Only other advice I've got is to not get too crazy pumping grease into them. It's fairly easy to blow out the rear seal if you are overzealous about greasing. Pumping it in until the spring loaded cap moves a bit is about right.

The bearings savers you see fitted to Indespension's trailers (the sprung loaded type) generally (only generally - before anyone shouts! ) fit only their own drums. The bearing saver size is 50.25mm.

Most Peak drums, for twin axle trailers, have a 51mm dust cap size (200mm and 203mm). The larger drums (250mm and 300mm) have a 70mm dust cap size. It'd be worth whipping a dust cap out and accurately measuring the internal boss diameter. Don't be tempted to measure the dust cap as they often distort and will give you a false measurement! Obviously, that 0.75mm means that the bearing savers will just drop out though if you have the 70mm size boss then you could get a packer / shim to make up the difference.

Beware false imitations too! You can buy 'bearing savers' and 'bearing buddies', but they're not sprung loaded. Ergo, you've just paid for a glorified dust cap with a grease nipple in it....

Sorry, all sounds a bit gloomy, which wasn't my intention - just want you to make sure you get the right thing!

I emailed peak the other day to see if they can tell me the size where is the best place to get them.

No might ring them next week we have a indespension centre near by will go there and ask I have all the serial no, the trailer needs new brakes bearings etc towing a 6.5 m rib with no brakes is not much fun.

I've got Bearing Buddies fitted to mine and I've just seen off the third year without bearing replacement.

Am I lucky? What's your experience of these?

Hi Hightower, I think you're one of the sensible ones who keeps them topped up with grease ...

A lot of people assume they work the same as a 'bearing saver' i.e. continuous pressure pushing grease in, where as they just act as a reservoir. So if you don't keep them full of grease they won't do much.
