drain plug

Recommended Posts

Take you drain bolt to a hardware store and buy a larger tap and matching bolt with crush washer. I found my oil drain bolt to be one size larger than stock. Make sure to buy the same type of thread for the new tap and bolt.

My dealer told me this was very common because the cases were really thin.

Good luck.

I understand what you are saying & the dealer is correct...But...where the drain bolt is fitted, is usually thicker than the case. Drilling & tapping will only get you closer to the even thinner case area. :thumbsup:

time-sert is the way to go...i did mine to my cracked case. I only had about the thickness of the case and maybe 1/2 of the thread bosses....it's not 100% leak free just quite yet, but I didn't have much material to go with.

m10-1.5 is what you need.

time-serts cost a lot more.
