Re: OMC vs HF flywheel puller UPDATE

[wetwillie]

My puller arrived this afternoon. That’s one serious puller! However, as much as I hate to admit it, I used it wrong. I positioned it with the flat side down vs up. Man, was that ever a mistake! I wound up bending one of the shouldered bolts that came with it because the bolt head was resting against the domed side. When I realized what I’d done, I positioned the puller properly and tried it again. I used the same bolts over again (my 2nd major mistake) because the bend was so slight. As you can imagine, I’m glad I was looking away when the bolt snapped at the shoulder. It took awhile but I was able to get the threaded section out of the flywheel. Thank you God!
Next, I bought another set of bolts (Grade 8) and tried it again. I had a 2′ extension on both the breaker bar and the bar that goes into the side of the puller. All was going well until one of the new bolts snapped. I thanked God again that I was able to remove the piece that was still threaded into the flywheel.
Unless someone has a suggestion, I thought I’d try it again with another set of new bolts of a higher grade. To increase my chance of success, I thought I’d try cooling off the end of the crankshaft with a can of compressed gas turned upside down after heating the flywheel up with a Bernzomatic torch.
I look forward to any other ideas if someone has one.
