Hello I am changing out the timing chain on my 2011 Mazda 6 2.2 diesel and have hit a brick wall. Tried to remove the oil pump chain but cant seem to get the sprocket bolt off. Took off the sump and used a wrench and breaker bar and it wont budge. Are they reverse threaded? Any help would be appreciated. Thanks

Hello, for everyone who been surfing internet like Bebop and I did, and did not found any information, i'm writing this comment for you. Yesterday I've managed to remove that bolt. Thread is regular, not reversed. I've used cheater pipe with 26mm wrench to counter hold against the floor and unbolted using another cheater pipe. Bolt was really tight, the moment when it loosened, it seemed like it snapped, but it did not. Moment was scary, but manageable. Good luck to you all. My vehicle is Mazda 6 2009 2.2 Diesel 136kw (185HP)

Edit: By the way, tightening torque is 123-140nm
