my alternative was to get 2 steel plates about 1/8th inch thick (or thin enough to fit between the hub and the case) and kinda didn't matter the dimensions but there was stock about 1.5"wide and about 4-5" long. when you remove the fan there are 3 long, i think 8mm bolts. to remove the hub, take the 2 pieces of stock and one should fit under a screw hole in the hub and the other should fit under the other 2 screw holes in the hub. screw in the bolts into the holes in the hub until they touch the stock. the stock is under the hub, over the case: between the hub and the case. gently screw in the bolts to put force outward on the hub, probably alternating tightening each bolt a little at a time. the factory tool is a u-shaped metal piece that esentially does the same thing.

[/quote] Yes, exactly zactly breath... Rich [/quote] so providing i pull this off, literally, should i assume that after installing the washer and the new seal the hub will just slide baqck on? |

Yes, its a tapered fit that gets held in with the single bolt. You can heat it to expand it a bit, but I have never needed to do that. I cant remember the torque specs, but you really dont want to go over that spec...its a threaded hold in the end of the crankshaft.. not cool to futz up. There is also a key, dont loose it. Rich |
