(1/3) > >>

frosty:

   Hi all,

    Ive diaganosed my over heating problem as a failed viscous unit but now i need to take it off, ive got a 32 mm spanner for the nut on the end but i was wondering how to stop the unit turning..

 any ideas?

Axetamer:
stick a big allen key, drill,  screwdriver, bit of bar or whatever in one of the holes in the pulley to stop the whole lot turning when undoing the coupling

Yes, left hand thread

richo:
No they are not as iv'e just had mine off [td5].My mate told me to give the spanner a light tap first with a hammer.
They do seize up sometimes.
I jammed a big screw driver between the nut and levered it down againsted the screws on the pully wheel.
