2004 mazda 6 3.0L V6 main bearing caps(bootom end) has 16 bolts need torgue specs please!


Okay, the main bearing caps only have 10 bolts, i think your looking for the connecting rod caps, they have 16 bolts, i will list them both, theres a tightening sequnce for the main bearing caps, these are the caps that hold the crankshaft to the engine block, the connecting rod caps hold the pistons to the crank and they have 16 nuts,For a 2004 mazda 6 with the 3.0 engine the torque specs are as follows.
Connecting rod bolts step 1) 19.2 - 23.6 ft lbs.
step 2) tighten an additional 80 - 100 degrees

Main bearing caps step 1) 32.5 - 33.9 ft. lbs.
step 2) tighten an additional 175 -185 degrees.
heres a diagram for main caps to tighten in order.
hope this is helpful.fc3bff9.gif
