B crankshaft pulley removal

We have encountered that problem many times on the C-113/123's. I remember some that, even with thpuller installed, we still had to heat red hot with a rosebud to remove. You're best bet would be to see if you can borrow or rent a T-puller and a bearing seperator form a shop in your area.
The bearing seperator goes behind the flanges on the pulley and the T-puller bolts to the seperator. The T-puller shaft "should" fit through the hole in your pulley. There is another way to take these pulleys off without that setup. If you remove the crankshaft and unbolt the front cover from the engine, you can then put the offending pulley in a press to do a more accurate job. Many other like you have had this problem & failed and so you should be able to find a new(aftermarket) pulley somewhere close. I know we sell quite a few at the yard I work at. Good luck.

You said that you already had the front end off so you are ready to have a go at it. Since this is basically just a press fit it is going to be a tough pull. I have always had to use the act. torch to heat it up. Becarfull not to let it drop on a concrete floor. If it lands on the edge of the pully it is for sure to break it. Another sure way to break it is to try to pull it with out using the split bearing puller.

GOOD LUCK
