Proper G900 torque values.

Joe Pro · Feb 4, 2015

Hey guys, I'm looking for the proper torque values for the main bearing caps on my D-451 engine.

The IT book says
M670 Super 280 & 170
G1000 240 & 140.

My G1000 shop manual from MM says
280-285 but it is crossed off and 240 is wrote in, and it says 170-175 for the 5/8" bolts.

What the heck are the correct torque values?

The 670 values will work. Same size bolts.
Those it manuals are too broad for me too. I
like factory books. I don't know why the values
change when the size of the fastener doesn't
and that's what matters.

front (3/4-inch cap screws) 240. Intermediates and rear (5/8-inch cap screws) 140.

Proper G900 torque values.
