Piston Rod Bearings?

I have removed the oil pan and got to the piston rod bearings and seen that the one of the piston rod bearings was wearing down and it was the cause of the rod knock. I am now looking to put things back together but I need specs for the piston rod caps (torque and sequence).

Also, Need the specs for the baffle bolts (torque and sequence) if any sequence is needed.

As well as the oil pan mounting bolts specs (torque and sequence) if needed.

Here are the specs for the 3.7 liter v6 engine:

Rod cap bolts: 17 ft, then 32 ft then 90 degrees

They don't have any specs for the rest, All I can tell you is tighten in a spiral pattern and don't over tighten.

Let us know if you need anything else.

Question previously answered but got the answer for a 3.7L engine.

I have removed the oil pan on my 2011 Forde Edge SEL 3.5 L engine and got to the piston rod bearings and seen that the one of the piston rod bearings was wearing down and it was the cause of the rod knock. I am now looking to put things back together but I need specs for the piston rod caps (torque and sequence).

Also, Need the specs for the baffle bolts (torque and sequence) if any sequence is needed.

Okay, here you go: 3.7 liter.

Piston rod:

Torque Step 1: 15 ft-lb (20 Nm)
Step 2: Turn an additional 90 degrees
Type Torque-to-Yield (TTY) - replace rod bolts when removed
Sequence: Torque both bolts on each rod cap evenly and in two steps (alternate between bolts to maintain flat seating)

Oil baffle and pan

Torque 89 in-lb (10 Nm)
Sequence Start from the center of the tray and work outward in a criss-cross/star pattern.

Let us know if you need anything else.
