Hi,

For some reason, the manual doesn't provide a sequence. It does indicate 71-inch pounds. (See pic below)

What I would recommend is to install all of the bolts hand tight first. Then, starting in the center and working in a crisscross pattern, tighten them to 35-inch pounds and then repeat the same thing to reach 71-inch pounds.

Note this is inch pounds and not foot pounds. Don't overtighten the cover. It can break.

Let me know if this helps.

Joe

Thanks for your quick response. I will definitely follow your recommendation in terms of sequence and torque specs when I do the job tomorrow and hopefully no more leaks. I will keep you posted.

Hi,

Thanks for the update. I'm glad you got it taken care of. Drive it for a few days and recheck the torque just to make sure nothing has changed.

Take care and feel free to come back anytime in the future.
