Ok, thanks - so did you drift the old viscous coupling off and refit the new using a B&D Workmate and hammer rather than a press ?
I think I will replace the v.c. instead of going down the electric fan route, partly for originality but also because it's about half the price of a Revtec kit and from reading some past posts, the electric fans don't seem to be any more reliable anyway. I'm sure there are many out there that have been trouble free but failures are not unheard of so....

When I rebuilt the motor of the 7, about 7 years ago I replaced the radiator with a new stock part, & fitted a complete new viscus fan assembly.
My 7 operates in our 35C+ summer days, running the air conditioning quite happily, without the temperature gauge going more than a needle width past the quarter mark.
I went the other way with the 8. Big 4 core alloy radiator, twin 16" fans, one in front & one behind the radiator, & it still struggled. I reckon the stock system is more likely to do the job than most modified systems.

That's correct, with socket on the pulley shaft. Most force is needed when removing the old coupling, but that needs replacing so support under the coupling. Any damage to it won't harm!
When refitting the coupling it can be supported under the rotating part of the pulley assembly. Gently tap in position using a correct (outer) diameter socket on the couplings inner ring.
