Motorcycle Repair: 1982 Honda CM450E Oil Change disaster!, 1982 honda cm450e, replacement bolt


Question
Help!  It's the end of the riding season here and I'm preparing to winterize the bike. After 3500 miles this summer commuting, I'm trying to change the oil. The drain plug came out fine, and after positioning the oil pan, I caught most of the old oil.
Now the problem: I fit my 15/32 socket wrench onto the oil filter panel bolt, and attempted to turn it lefty loosey. The socket broke in two places, ruining it.  I ran to the neighbor, and borrowed his 12 mm socket, and with him watching, I again tried to turn the bolt. AGAIN, the socket sheared and was ruined. The bolt is still in place, intact, holding the lid on.
I gave up, re-installed the drain plug, and refilled the bike with 2.5 US quarts of Motorcycle oil 10W-40.  I would have liked to have replaced the oil filter before putting the bike away.

Do you have any suggestions. I'm worried about shearing the bolt or rounding the head now. How important is it to change that oil filter.(I can aford another $8.00 of oil to be changed out, if the oil filter can be changed. ) Or do I even need to worry about this?  HELP!

Answer
Kirk, the bolt is metric, of course, and when overtightened can really get stuck in place.

I would suggest that you find a 6-point impact socket of the correct size to loosen the oil filter cover bolt. Using a 1/2" drive breaker bar and a matching 1/2" drive impact socket should get it loosened up.

to check the part numbers for a replacement bolt, if necessary. Do change the O-rings for the shaft and cover, along with the filter.
