viscous fan bearing removal from shaft td5

[greatrob59]

I recently removed the viscous fan bearing and shaft out from timing case cover.(from my td5 2000 model)

I have been told that the bearing and shaft are two seperate parts.

I wish to remove the bearing from the shaft have given it a few light taps however no luck..is there a c clip holding it on..or is it just firmly pressed.

I have also been told that when replacing it to place the new one in boiling oil..this should make it fit easier???

Hi Rob.

The shaft is just pressed in (interferance fit).
I screwed the addapter back on and gave it a "love" tap with a wooden mallet while rest bearing on vice jaws.

I think the seals on the bearing would fail on that hot oil.
Refit is simple, close jaw to fit inner race and tap shaft back in.

Still like the idea of placing this assey. in a bag and frezing o'nite to refitt in timing case.


Cheers.

Thanks alien..kinda cheated on this one had to go into Newman (W.A)today 195 klm unsealed track to get a work car serviced..i took the bearing in with me..and asked the mech to seperate it...great service he did it..was on the front seat seperated when i went to collect the work car bearing shaft seperated.Just hope the new bearing goes on easily...are you aware if the bearing hub should have alittle lube on it..when it goes back in???

A rang good mechanic freind of mine back in Perth .and he has let me use his wholesaler supplier in Sydney for a new harmonic balancer....still 800 bucks though compared to a $1000 i was quoted by rova craft perth.New bearing should be arriving maybe Friday...Theres a 2 week wait for balancer

Mine looked like it was a sealed unit so no lube needed.
Can't look at the new one yet.

I am replacing the Td5 viscous pulley bearing. I read on a uk forum that the bearing is a commonly available one. Does anyone know the generic number for it?

I managed to get the bearing out of the front cover by placing a piece of wood against the front cover bearing flange and screwing the pulley hub back on and up against the wood, then turning the allen key up until the bearing withdrew from the front cover.

Thanks for the measurements.

I checked today at for a match but no luck - there was a bearing around the same size but the speed rating was not suitble. Given the harsh environment I think I will pay the price and get the OEM bearing.
