Title: How to remove a viscous fan bearing on a TD5
Post by: Smokydiesel on January 17, 2009, 18:34:48

Hi,

I have a bit of a problem here.
After half a day I finally got the Viscous fan bearing out..........pfffff

The bearing came out together with the axle stump (the bit where the pulley-flange is screwed on).

But how on earth do I seperate the bearing from the axle stump ?????   :x
I grinded off the outer bearing ring, so now I am stuck with the axle inside the inner ring of the bearing.......and 15 bearing-balls all over my workshop....

Any idea's ?

Thanks !
Edwin

Dremel grinds......

Seriously, be dead careful and grind the race away, the heat and progressive weakening mean it will relax and start top spin before you cut through, otherwise try shattering it before you cut right through.

I was once told that electric arc welding would crystalise bearing race metal making it brittle so put a blob of wleding on the race then chisel it, but I suspect again the heat had more to do with that trick working.
