Your situation is precisely what I used to be making an attempt to cowl right here.

Lengthy submit…SORRY upfront…
This submit covers each R1200/R1250 in addition to K1600’s that I do know of…possibly others
Fundamental information for Fill and Drain Plugs
Sealing:
Only a copper 12x16mm crush washer for the fill plug (6mm Hex drive) and the 11.2×1.8mm O-ring on the Drain Plug (T-45 Torx). Each get torqued to 20Nm.
Crucial to not guess on this, because it typically damages the FD drain threads as proven within the footage.
Drain Plug Frequent ISSUE:
“Stiff to screw out, then had problem getting it again in”
Often, after breaking torque, the drain plug seems straightforward for a couple of flip to a flip and a half…then turns into very tough as a result of smashed threads within the FD housing.
It is because there’s a small hole space between the seating flange on the drain bolt and the primary withdrawing thread on that drain bolt. When the primary thread, closest to the T-45 finish of the drain plug, reaches the alloy thread of the FD that was deformed, it’s now “reducing” new threads to be eliminated.
Since these threads aren’t being correctly minimize/chased to OEM customary tolerances with the elimination of the drain plug, upon making an attempt to insert the drain plug later, it turns into very tough to get engaged correctly and there’s a nice probability to even cross thread it and harm the FD.
SOLUTION:
The answer is to “chase” the drain gap threads with an M12x1.0mm Bottoming Faucet to reestablish trade customary thread configuration that enables correct set up of the drain plug.
Utilizing a bottoming faucet is crucial right here due to the shallow drain gap, (variety of threads) and the shut proximity of the FD Ring Gear inside the housing limiting how deep you may run in a faucet.
The final picture exhibits how neither the TP-40 (TorxPlus) on the left, or a T-45, on the correct, is EXACTLY the right device for this drain plug…however the T-45 is your best option.
Listed here are some images that specify why that’s, and learn how to appropriate this.
