DAF T244 front hub 'tracta' joints

Postby Tom_DAF » Wed Nov 14, 2018 10:11 am

Hello again resident experts. I had a day to do some truck inspections today and thought I would check the oil levels in the tracta joints as I read they are prone to leaking and need topping up.

I removed the square drive nut and the levels seem okay, but the oil is grey and sludgey. The manual says the oil never needs to be replaced, just topped up. There is a magnet on the nut which had attracted the sludge so it's ferrous sludge. My question is, is this typical or do I need to be concerned?

I cannot understand how you could never be required to change oil, it is just not right!

There must be metal on the magnet as everything wears, it has to, so why design something that cannot be drained....

I have not changed mine, and most of the time I do not have a leak, but I think I will look into a way of siphoning to old oil out, if at all possible, as it is quite a thick oil.... Maybe when it is hot after a long journey......

Sorry, not a lot of help....

Thanks Brian, good to know that the oil is thick on yours too. I'll get some SAE80W90 and keep an eye on them.

I've replaced one wiper seal on one of mine as it was weeping a bit too much for comfort. They nearly all weep and that's just how it is. Even though the loss might look quite worrying it usually only takes a tiddly bit to bring the level back up.

It wouldn't hurt to change the oil from time to time but a bit of sludge and magnetic detritus is nothing to worry about. If they start running hot or clonking they're unhappy.

Thanks Steve. I won't be too concerned then, I'll just keep an eye on them.

I understand that if I need do need to remove the hub I need a special tool and that a limited set was made recently on facebook. Are the drawings/CAD available for these? Perhaps I could have one made out here?

The tools were commissioned by two people who are currently heading for the far east in their trucks. I'm pretty sure the UK firm that made them has the design on file and will make more - though one-offs were quite expensive compared to the relatively large batch recently made.

Brian will probably be able to communicate with the two chaps that commissioned the tools to identify the company that has the design drawings / manufacturing experience - he's on a facebook group that they post to.

It is possible to butcher the hub nut off but the problem comes with how to fasten the hub back on having destroyed the correct castellated nut.

As Steve has just mentioned, I can see if there are going to be anymore made as I think there was someone not to long ago after one....

Another member I know actually made one himself by welding some tool steel onto another machined bit of steel, by he is clever like that!

In the mean time, I will see if anyone else is interested.... you could of course join the T244 FaceBook group, some good people on there, but some of the people do not know how to discuss things which spoils the group.... a shame.

LEYLAND DAF T244 GROUP....Aka The Duff Club is the group name.

As for the hub seal, I find it very weird how one minute my right side seal leaks and dribbles down the tyre, and other times, nothing..... weird..... and this is when it is parked in the barn in the same place...

Changes in temperature, Bri. It's a significant factor...

Are they the just escape guys Brian? The thing is the postage. I'm certain I could get one made here. I'm not into Facebook but could revive my account if that's what it takes.

I think it probably was Sir. Steve will remember as he has not yet got his.
