G'day Folks,

I'm trying to re-seal my power steering pump. It is a Vickers type 24, 65 bar, model that seems to be fitted to most W123s I've seen.

I'm a bit stuck trying to get the pulley off (everything has been pretty much stuck fast on this car so far). There is an arrangement with woodruff key on the shaft that helps to hold the pulley in place but perhaps is also making it harder to take off!

Question 1

How have people before me removed their pulley's - pullers, bashing and heat?

Question 2

Is there a special tool - a partially circular socket (like two half moons facing each other) - available for undoing the nut inside on the other end of the pulley shaft to release the inner bits?

Any help will be greatly appreciated (before I just install the secondhand replacement I got and hope for the best!)
