Posted: Sun Oct 27, 2013 12:54 am Post subject: Should we lubricate our balls ? |
|
|
Since the 1950's, in England, my parents, family and friends have owned a variety of trailers and caravans.
One thing that was always considered important was to have a clean, (free from grit and dirt) but lubricated (grease) ball and socket coupling.
In engineering terms it makes sense, as dry metal to metal is to be avoided as much as possible.
After moving to Canada, I have been consistently surprised to find that trailer couplings remain dry and a quick look around any car park will reveal a majority of rusting balls.
Is lubrication a British thing ? I would love to hear the opinions from forum members around the world. |

The modern ALKO hitches must not be greased as it contaminates the "plastic" pads that are inside the hitch head. Their advice is to thoroughly clean your tow ball with white spirit or similar to get rid of all dirt, grease,
etc. before hitching up.
What damage is done by a rusty ball inside one of these "advanced" hitches?
Like you Peter, I prefer you have my balls well greased to avoid chafing and to stop them rusting. _________________ Brian

I do, it just seems a natural thing too do, and as it can be weeks or longer between towing it stops things rusting, something that also seems sensible

| BrianM is right,. Modern caravan hitches must have dry balls ( Ooh, that sounds painful!) Grease will ruin the friction pads. Those of us with older vans and trailers don't have a problem, but trouble can arise if you have mixed old and modern hitches! |

If you have the older type of bolted hitch, have 2 and keep one dry and the other greased, likewise if you have modern swan neck removeable hitches; what you do if your hitch isn't removable I don't know--- is it reasonable to use a tradtional hitch dry? _________________ Bristols should always come in pairs.

I suppose that would depend on the length of the tow. BrianM and I sometimes tow for long distances in Europe. Dapping around locally wouldn't hurt, but the 4,000 miles I towed back in the summer (?) would not have done much for either ball or hitch. |

All our towballs and our caravan hitch are greased , we have no intention of changing our classic caravan and so the need for a dry towball will not arise . _________________ 1968 Volvo Amazon estate (Gracie)

I had to ask the wife and she said old greased balls is the way to go....
However, I have heard that the new fangle anti-sway hitches should be as dry as dry can be. _________________

So how do we determine if we have a "Modern hitch"?

It'll be one of them with a built in anti-sway locking thingy... An Alco one I believe? _________________

That's right, and you can identify it by the big red handle, which must be physically pressed down hard to engage. Take a look at any new caravan and you'll see the difference. |

Ahh ok, so it's not modern hitches on trailers but only those with stabilises, ref an earlier post...
Still unsure how grease attacks plastic?

Dave | If there is grease on the modern Alko type the plastic locking anti-sway won't work.
I can't see that the grease will do any harm to the plastic itself though.

If you have old or vintage balls they have to be greased to stop friction wearing them away.  _________________ I can resist anything except temptation ! ( Oscar Wilde)

As usual I was talking a load of balls. (No need to censor as that was the topic!!)
I spoke to an owner of a new caravan who put me straight - Grease doesn't contaminate the plastic pads, it just stops them working. They are designed to grip the ball to prevent sway, so a greased ball defeats the object.
So my next question is how do they know when it is a sway and not the outfit turning a corner?
I never will understand this new technology  _________________ Brian
