Torque Settings for 997.1 Drive Belt Idler Pulleys (Rollers)
Anyone know the correct torque settings for the two drive belt idler pulleys (rollers) on a 997.1 3.8? Pelican's DIY article on the subject doesn't mention them, only that the tensioner pulley should be torqued to 44 Ft-Lb. The Torque Settings thread in the DIY sticky here on rennlist doesn't address it either.
I found the following values listed in the 986/987 Boxster section on Pelican, but I am not sure if they would be the same for a 997. According to the author, the 986/987 bolts should be "tightened to 34 ft-lb (46 Nm) for the upper bolt if it's an M10x145 (8.8) bolt or 48 ft-lb (65 Nm) if it's an M10x145 (10.9). The lower pulley is tightened to 17 ft-lb (23 Nm)."
The tension roller for both the 997 and the Boxsters is torqued to 44 Ft-Lb, but I didn't want to assume the idler rollers were the same between the two models.
Thanks much.
