Flavia Coupe 2000 (1970) - front hub bearings

[msh2908]

sadly i've worn bearings on my coupe 2000. Does anyone have a copy of the workshop manual section on how to remove and replace these please?

How do you know they are worn? If you undo the drive shaft nut they will go loose. Test when drive shaft nut is done up tight (200mkg). If they are worn you need to check the hub itself and the hub can wear then you will be looking for a new/second hand hub

Thanks for these thoughts, the wheel and hub assemble is still in place, so no nuts undone yet and I have movement in the hub when I grab the wheel and put it under vertical and lateral pressure - so the wheel hub has to come off.

My bearing told me with loud whine that it was knackered. Need correct tools and long length of pipe, is a very high torque. Best replace all retaining rings etc. 1970 Flavia can use S1 Fulvia bearings, I luckily had a spare lying around, they are now quite expensive

Is it not 200 Nm for the hub nut.

200Kgm is equivalent to ~2000Nm and that would be like 2 fat guys sat on the end of a metre length of scaffolding pole.

mistype I meant 200ft lbs which is a guide as really cannot measure accurately. A long pole (I use a 4ft length) of water pipe is essential though as is also a way of holding the nut tool tight to the hub to stop it spinning off and getting ruined.

I bought a hub nut tool from Omicron (~£70) that had a bolt which screws into the end of the driveshaft so you can secure the tool in place whilst applying load on it. You can also hire this tool out from them and the Flavia Consortium used to have a similar tool for members but I think someone forgot to return it.

I used a 1.5 metre legth of scaffold pole (bought from a local metal factor) I marked a band on it about 1 metre from hub centre and then used bathroom scales positioned at the 1 meter mark to measure the force that I was exerting on the bar with my body weight whilst my wife used the brake pedal to stop hub rotating.

The last time I had to do the job on my previous 2000 Sedan I chickened out (Correctly as it turned out), so took it to Omicron.
They said it would be a ‘While you wait’ job, so Elizabeth kindly made me a coffee and a sandwich from her lovely bread maker whilst I sat in the sun whilst the job was done.

At one point I walked into the workshop, and despite having all their experience and the correct tools, they still had two of their chaps hanging on the end of a scaffold pole with their feet off the ground attempting to undo the hub nut !
Eventually it came loose and the replacement was quite straightforward (For them, not me).

So I would never even attempt it, far better to get the professionals on the job.
