Bought the Bently manual and there is NO bottom end data at all! What a rip off. Anyone know the correct torque for main bearing caps and rod bearing caps??
I have gotten a load of junk at Bimmerforum- so beware I actually have built many engines. Just never a BMW before.
this is straight from bmw.
Tightening specifications for main bearing:
1. Tighten all screws on main bearing cover with jointing torque. 20 nm
2. Unfasten screws on main bearing cover 6.
3. Strike back and front of crankshaft with plastic hammer to centre thrust bearing (do not damage crankshaft).
4. Tighten screws of main bearing cover 6 with jointing torque.
5. Tighten all screws of main bearing cover with special tool 11 2 110 or special tool 00 9 120 with torsion angle. 50 degrees the special tool is a angle gauge.
after jointing torque. then turn all screws 50 degrees.
