another solution is to take the pan off, and drill out the bolt holes. The ones in my 1650 are now 7/16 fine thread, tightened almost to the point of stripping. I used brand new bolts and washers. That tractor shakes like a (bad shaking tractor) at all speeds accept WOT.
good luck

alright. ill look around and see if i cant find one. for now i put some locktite on them to hold them in place, its a low strength so it wont take much to break them apart again.

I've done quite a bit of helicoiling in my day-

I will say they are used on all aerospace applications for a long time. Good product and you can get an automotive kit for the bolts from amazon for $18 or so. I would do both LHS bolts. If the pan has severe wear on the bottom- you might consider replacing it.
Helicoil is stronger as it provides better load distribution to the first few threads which take most of the load and it effectively is a bolt size bigger.

I just did a bolt on my 1650 as it was stripped.

I tried finding a decent pan on ebay- BECAREFUL. Most of those used lawnmower guys say in their write-up- no warrantee.
I got a cast iron pan and it had a HUGE crack. Twice the guy insisted it was free upgrade and he would give me the "superior" aluminum pan. Dispute and he *had* to get his pan back with the huge crack... Ordered up an aluminum one from Patton's and it was useable but had a stripped thread.
