We have a '47 Chief that we cant remove the oil drain plug. It's the very small brass plug. We tried refiling the square for a wrench and then vise grips, cut a straight at the head for a screwdriver and nothing worked.

We don't want to put flame on it because of possibility starting a fire. The only option we can come up with is pulling the pan and that requires pulling the motor out. Then we could drill it out and put a Helicoil in.

Does anyone else have ideas? The bike has been completely restored by pro's and we are very versed in motorcycle engine repair/ rebuild.

Just looking for any other original Indian owners that might have an idea.

Not an owner, but work a lot of old equipment. What diameter is the plug? If large enough for Blue Point splined extractor, then drill and install the spline for successful extraction. Look up at Snap-On tools.

Thanks for the quick reply. The diameter of the threads are about a quarter of an inch and the head itself is even smaller.

We also don't want to drill with the pan in place because we don't want any shaving pushed into the oil pan.
