Re: OMC vs HF flywheel puller

[wetwillie]

I have not considered the position of my mouth, but HAVE found myself muttering various words. The ones prior to tightening the center bolt to be far different than those expressed afterwards. I would not be surprised if my facial expressions change during each attempt as well.
As for using a ball of foil for a heat shield. I have not but I really like that idea and will most definitely try that the next time around. As for a heat source, I’ve been using a Bernzomatic propane torch. I have also been using the exact type of coolant as you described. I have had the flywheel hot to the touch and the nut/crank end, literally, frosty white.

For anyone interested in an update, I ordered a set of Grade 8 shouldered bolts from Fastenal this morning. I also ordered a set of Grade 9 bolts. They are due to arrive on Wed. At which time, I will do everything that has been suggested in the preceding posts including different facial expressions as I torque the sucker down.
Also, I have done a little research to satisfy my curiosity re: the difference in tensile strength between grade 8 and 9 bolts. I was disappointed to learn that although the grade 9 bolts have higher tensile strength, they are more brittle and do not handle shock loads very well. 🙁
To be contd.
