Disco 2 Three Amigos Issues - thoughts needed.

Normal breaker bar etc is a bit under tooled. I bought a 1000Nm torque wrench for the job. Needed to correctly torque the nut back up to 490Nm when new one goes on.
Can't beat a larger than needed tool for making hard jobs easy. (Cost £70 off eBay, but I've hanged 5 hubs now, so I've got my money worth from it)

Aye, tried it with a cheater bar too to give me about 6' but all I got was bent bars. Could have done with some scaf bar but didn't have any.

Bit the bullet - Gone to the garage this morning for them to get it going for me.

Ha ha - It would be nice not to need change five hubs.

For putting it back on I figure 100kg of me @ 500mm should give me 490 Nm.

One thing I've learnt, buy a hub with the wheel flange already mounted.

Taken me two days to pull apart the bearing and get into a position to reset the flange into the new bearing. Have about 20mm left to drive it in but think that's all I can be bothered with tonight.

Don't have a press so ended up knacking a couple of bearing pullers to do the job:


Annoyingly the inner race came off with the flange so needed to pull that separately. Lip on it is next to nothing but with some effort I could cut a pair of grooves into the side wall:

Need to the clamps to hold the puller arms together but even then it slipped off every couple of mm pulled. If I did it again would probably cut a groove all the way around so it didn't slip out in the same way from the torquing action.

Finally off & tidy:

Spot the snapped bearing-puller arms in the background. Bonus - managed to chew up the ends of a couple of the splines but otherwise they didn't look too worn so hopefully can just tidy them up with the fine file.

Without a press, definitely would think twice about doing this again.

The easiest way to get the bearing centre off the hub is run a 1mm cutting disc into it you will have to go in at an angle ,watch not go too deep and into hub,once you go as far as possible without cutting the hub,get a sharp chisel into the cut groove and a good smack with a big hammer splits the inner race and you can pull it off with your fingers takes only a couple of minutes.
