Hi all,

New user here, but looking for some info I am otherwise struggling to find. I have a 2015 Craftsman T1600 with a 19 HP B&S engine, model number 33R877-0007-G1. I need to run a tap into the crankshaft snout to clean up the threads so I can bolt the fan and cover back on the flywheel, but I cannot seem to find anything definitive telling me what the thread pitch is. The bolt backed out after a fan replacement and it sat there long enough that it boogered up the threads and I can't get a new bolt to thread into the snout. The bolt part number is BS-698139. Any help would be appreciated! Thanks.
