CAUTION: do not use the washer that comes with the Moose magnetic Drain Plug. It is steel and does not allow you to properly torque the bolt. It prevents the plug from engaging the proper amount of threads in the case. When I attempted to torque the plug the steel washer did not compress and the first two rounds of threads pulled out. I removed the plug and replaced the washer with a brass washer. I installed the plug and firmly tightened it down (less than the recommended torque in the manual). It comes with a safety wire hole that I use to ensure it does not fall out. This has worked for a few months; however the plug has gotten looser. I am now looking for a heli coil to replace the threads. If anyone knows of a good heli coil kit please respond. I guess I should have gone with Scotts bulk buy!
