How do you remove this without breaking it? I hear the mag is pretty fragile. I tried tapping on the "hub" from the backside but it didn't budge.

I'm not nearly as well-versed in six cylinder parts-n-pieces, but can't you unbolt the alternator and pull the fan/alternator unit out together? Seems like it would make it a lot easier to hold the fan... (IMG:style_emoticons/default/confused24.gif)

(IMG:style_emoticons/default/confused24.gif) Yes and No.....The bolts that hold the alternator halves together go through the fan housing as well. On numerous occasions I have tried to unbolt them only to have the long bolts spin requiring to hold the bolt heads that are under the fan. Normally it only takes a "tap" with a brass hammer since it's not an interference fit and I have never damaged a thread doing so. They normally slide right apart. However, that is why I mentioned heat if a "tap" didn't work. A little heat (oxy-acetylene)around the hub and you can usually lift it right out without anything. Yes, a brass hammer can do damage if you don't use it right. In fact I can drive nails with one if I hit hard enough......However, a straight "tap" at a 90 deg angle should have done the trick with no damage at all...Done it many, many times. If it requires a "blow" than heat is a good method combined with a "tap" You can also use a piece of hardwood on top of the shaft for more protection but get lesser results. |

The long bolts were difficult to remove as well. They would not fall out after i removed the nuts and had to apply quite a bit of torque to thread them out after the fan was removed. No doubt this would have worked fine with a brass hammer and/or a block of wood, I just couldn't hold the fan and tap at the same time and needed help. My fault, I should have waited until I had another pair of hands to help out (besides the wife). Kev |
