Wobble rollers

Bucksribster · 20 April 2018, 14:15

I have an SBS trailer with lots of wobble rollers on swing arms. The rollers are held on by star washers. I have lost count of the number of these rollers I have lost over the years as the washers rust, and the rollers fall off into the water. On the first trip of the year yesterday, I lost five!

Has anyone come up with a better way of holding the rollers on?

Put the washer on then a big tie wrap?

mine have split pins.
Still fall off when really rusty, I've decided to replace the washer before they get too far gone.

I've never had much luck with star washers. One good knock and off they come. If there is space, drill and pin. If not, large washers spot welded on.

Depending on the available space drill the arms and fit tractor style stainless lynch pins behind a solid flat washer

I have split pins on my Bramber, which seem to work pretty well.

I did replace a load over winter though, as they can rust and/or eventually get bent a bit out of shape due to load, and I had a couple of washers manage to slip over a couple of very badly rusted and bent ones, which maybe weren't particular well fitted in the first place.

Thanks for the advice guys. I have replaced many of the washers, and put two washers on them all, but they still come off.

If I drill the stub, will this start corrosion as the hole will not be galvanised?

Thought about some stainless jubilee clips, but would there be a reaction between the metals?

If you drill the stubs you do risk corrosion in the hole but if you drill big enough for the pin to be a loose fit with plenty of grease and stainless pins then that is about the best you can do
Corrosion caused by dissimilar metals is far worse in water than out so stainless fittings should be fine

I drilled & used stainless washers with stainless spit pins.
Think we're about 10 years on & no issues.

Looking at the stubs, they are recessed into the rollers, so getting a split pin in and out is going to be tricky. I have ordered a few jubilee clips off ebay and will experiment.

Yep I had same experience. lost 3 on the A31 a couple of years ago. If you think about it they could do a lot of damage if they come off when driving at any speed.

Since I lost those 3 I bought a large bag of new washers and replaced all the original washers with two new washers on each roller, then a simple inspection before I use the trailer and replace any that look very rusty, haven't lost any since.

I did find a blue wobble roller on the A31 a few weeks ago and picked it up for a spare. I bet there are dozens of em in the verges between Ringwood and Poole.

Drill and tap the end of the shaft put a ss bolt and washer to stop the roller coming off. Silicon grease the bolt well.
