How do you get the hydraulic fan pump pulley off...tried a rattlle gun etc etc do you have to get the 5 bolts off under the pulley?? Or does the whole pump assembly come off to do that?
And also what size belt are you using (ie a 5PK1250 ) ???

Turn clockwise on the holding bolt or you will strip it like Supra said.... Grab a Puller tool and turn the tool until the pulley pops out.. Make sure the radiator is protected or out of the car.. Mine popped and thrust back with some force.....
That was my experience with removing that pulley... Also this is a pic of my funky home made special belt setup minus the hydro fan pulley.... I decided to use one of the hydro pumps holding bolts as a idler mount... Drilled the hole a little larger and re-threaded it and slapped a universal idler on... Grabbed a measuring rope and matched that at the auto parts store to get the proper sized serp belt fit... Whalla good to go.....
Craig I happened to be doing this job tonight. Started at 7 oclock and think it's home time now. Cambelt, seals , bearings, waterpump, rotors and tensioner are now all done and there are photos of the hydralic pump stripped. We will weld up the extra water fitting on the thermostat housing and I will find a alternator to fit. PS will go back on with a new idle up. The motor must have been burning oil as idle up valve was leaking oil. Hope this helps. I will show the belt fitted up tomorrow.
The last photo shows three other engines which need preparing for fitting. One is all wired and has been running on the stand. Most will receive sump swaps , filter housing changes and header changes as they are all bound for different vehicles. This one is going into a 1995 KZN130 surf. Cheers
Hello Guys
You fellows are referring to the auto tensioner bolt which is a left hand thread. The hydralic pump front nut has a standard right hand thread. Craig doesn't need the a/c pump so no need for the hydralic pump.
