To save you time, Here is the solution I posted last year
"Went under the tractor with light this time to see if there was enough thread left in the hole to use an oversized plug, and yes, the old plug was catching but the plug would not tighten. Backed out the plug, looked in with the light and saw into the hole, it had some good looking thread at the top , got out the tape measure, original plug- 1/2" long, and depth of hole is close to 1" long and threaded all the way . let the search begin - looking for a 12 x 1.25 x 1/2 long" oversized plug, with or without piggyback, NO LUCK at three auto part stores, BUT, came home with a standard 12 x 1.25 x 1" inch long bolt. Back under the tractor, with a gob of grease on the bolt I gently tightened the bolt till it caught the good thread - snug to the pan and then backed it out - no thread or metal shavings on the grease, put original washer on bolt and tightened bolt to 15 ft. lbs. torque, enough torque for an aluminum pan? Yes? Completed oil change, after 2 hrs use no leaks and bolt is tight.
Since then I have found a Canadian supplier on the internet of the oversized plug with piggyback, FOR NEXT YEARS oil change, until then inspection of the pan and bolt is advisable before each use. Thanks to all for the advice"
P.S.
Just completed this years oil change 2010, reused the longer plug I used last year, have a oversized plug I ordered I will keep on hand just in case. Torque the plug this year to 17 lbs.
