So, its 8:00pm, and I am needing to take my alternator rotor off. The shop manual says to use a Metric 20 bolt, and thread it through the center of the rotor, and it will go through and push on what is behind the rotor. The problem is, I do not have a Metric 20 bolt, and none of the big box stores that are open have anything metric that large. I could probably go to fastenal in the morning and get one, but I was really wanting to get the motor taken apart tonight. I tried a claw puller that I have, but it does not fit well. Are there any other ways of taking this off that I could do tonight?

Tip:Once you have the Starter Flywheel off polish the crankshaft tapered end with some 500 wet and dry and clean off and lube with some clean engine oil when re-fitting.The securing bolt needs to be set to a Max of 72 Ftlbs.I use around 68/70 Ftlbs.

Although the oil filter bolt can be used in an emergency it's not recommended as they are brittle and hollow and have been known to snap into the threads causing more problems.Better if possible to get the correct tool or bolt.



My 2 cents.

Fastenall doesn't carry a metric bolt that large. Turn it in, tap with hammer, turn tap turn tap turn pull tap pull turn...... Do not use a puller as you can bend the starter gear behind the flywheel.

If all else fails, the "tool" (a hollow bolt) goes for $10 on FleaBay and any of the other sources that will likely come up in a google search.
