Steve Suttle Posted October 13, 2011 Share Posted October 13, 2011 According to the shop manual, one must remove the radiator to replace the fan pulley (the earlier one without the nut). It says that driving the pin might 'spring the shaft'Anyone out there had any luck replacing the pulley without removing the radiator? Link to comment Share on other sites More sharing options...
platt-deutsch Posted October 13, 2011 Share Posted October 13, 2011 Are you talking about the pulley that drives the fan belt down on the engine or the pulley just behind the fan? Link to comment Share on other sites More sharing options...
dwollam Posted October 13, 2011 Share Posted October 13, 2011 I don't think there is room enough to get it off the shaft. I tried that the other day on the '24 coupe. Assuming you are talking about the one down below. Link to comment Share on other sites More sharing options...
Steve Suttle Posted October 13, 2011 Author Share Posted October 13, 2011 Yes, I mean the pulley on the end of the fan belt. Link to comment Share on other sites More sharing options...

DoubleG Posted October 13, 2011 Share Posted October 13, 2011 You can remove the pulley without removing the radiator. If the pin holding the pulley to the shaft can be knocked out easily then you can simply tap the pulley towards the radiator and off the shaft. There is enough room to do this. The problem with it is that after so many years the pin and pulley will have almost welded itself to the shaft due to gunk and rust buildup and would require some heavy pounding to drive the pin out and to knock the pulley off the shaft.This action could cause you to spring the shaft or in other words damage it! When I first removed the pulley from my car I had to take the radiator out and remove the the pulley with the shaft still attached. You need the room to do this. Now, after the restoration of these parts, I can remove just the pulley as needed. You could try soaking the area with a penetrating oil over night to loosen things up. Then give it a go but proceed with caution. I would recommend going the safer route and remove the radiator first. It is not that difficult. Good Luck!

dwollam Posted October 14, 2011 Share Posted October 14, 2011 Interesting. I was unable to slide the pulley off on my 24 coupe. It hit the radiator. I have also never had one that needed replaced ever be tight on the shaft. They all have been flopping on the shaft, and if they weren't they didn't need removed. Now that I think about it, I wonder if how the radiator was adjusted fore and aft had something to do with that. Link to comment Share on other sites More sharing options...
Steve Suttle Posted October 15, 2011 Author Share Posted October 15, 2011 Thanks for the replies.The moron who installed this particular fan pulley did not use a pin.No, he opted for the ever-popular 10d nail, peened over.Needless to say, it came right out with a pair of pliers.So, what I have now is the remnant of the pulley (it shattered in 3 pieces)which is just the hub on the end of the shaft.Can I knock that forward without "springing" the shaft?I don't really know what "springing" means.

R.White Posted October 15, 2011 Share Posted October 15, 2011 Sounds like it's been off before so will probably come off easily but if it sticks, try applying a little heat to the pully hub. I personally would remove the rad and use an extractor; but it's your choice. Link to comment Share on other sites More sharing options...
Guest 1930 Posted October 15, 2011 Share Posted October 15, 2011 Springing means to bend, rad are not cheap so I would also play it safe and get it out of the way Link to comment Share on other sites More sharing options...

Steve Suttle Posted October 19, 2011 Author Share Posted October 19, 2011 Mission accomplished.The old pulley slid off the shaft after a light tap with a screwdriver and a small hammer. The new one slipped on after a minor filing of the woodruff key (it was just a bit too tall to accommodate the slot in the new pulley) and a gentle tap from the front with a small, soft mallet.I got lucky because of the improper use of a nail instead of a spring pin by the previous "mechanic." I would imagine a properly installed pin would be hard to remove.Works fine. And I didn't have to pull the radiator which is as said here not that difficult, but it is a rather messy job.

Steve Suttle Posted October 19, 2011 Author Share Posted October 19, 2011 Thanks to Bill and Ray for following The Saga of the Fan Pulley-2011.My wife says I employed a mechanic's skill I don't often use - PATIENCE.As for the nail, it and the shattered fan pulley are in my box of mechanical-failure treasurers along with a broken intake valve from a Land Rover, a Model T piston that blew apart on a tour, and various other breakdown souvenirs.I used a spring pin off the shelf from Auto Zone instead of a new nail. It easily tapped in with repeated gentle nudges from a punch and small hammer. Everything is tight and secure.This DB adventure has been something, but you DB club guys are a great resource. I'm glad I joined. Link to comment Share on other sites More sharing options...
