What is the torque on rod bearings?
Proper bolt torque: Torque rod bolts to 10 ft lbs on both sides, then torque to proper spec with one pull.
What are the torque specs for the connecting rods?
| Connecting Rod Bolt Specification | Steel Connecting Rods | |
|---|---|---|
| Part # | Dia. x U.H.Length | Torque |
| 90803 | 7/16″ x 1.940″ | 65 ft lbs |
| 90804 | 7/16″ x 2.320″ | 65 ft lbs |
| 90805 | 3/8″ x 1.920″ | 50 ft lbs |
What is the main bearing torque?
On the 3.0L engine, the main bearing cap bolts should be torqued in proper sequence to 14 ft. lbs. (20 Nm), then an additional 90 degrees and another 45 degrees after that. Also on the 3.0L engine, the connecting rod cap nuts should be torqued in proper sequence to 22 ft.
What is a torque rod?
Torque Rods – Longitudinal torque rods help maintain optimum driveline angles by absorbing axle braking and driving torque. This ultimately reduces vibration and helps prolong the life of driveline components.
What are connecting rod bolts?
Connecting rod bolts are the securing link between the piston assembly and the crankshaft. The rod bolts, because of the need for great strength, are generally made of heat-treated ahoy steel. Fine threads with close pitch are used to give maximum strength and to permit secure tighting.
What is a big end bearing?
Big End Bearing – Located at the ‘Big End’ of the Connecting Rod, where it connects to the Crankshaft. Flange Bearing/Thrust Washer – Located at the end or mid-way through the Crankshaft. Small End Bearing – Located at the ‘Small End’ of the Connecting Rod, where it connects to the Piston Gudgeon Pin.
Do you put Loctite on rod bolts?
It is the PRELOAD and only the preload that prevents fatigue cycles and fractures on something like a rod bolt. Loctite is good for non-rigid connections, like soft gasketed joints. I use it between the rod/main bearings and the rod/block to help avoid spun bearings–along with the bearing crush on the high side.
Is the connecting rod bearing torque to yield?
Haynes states that the connecting rod bolts are torque to yield for the main bearing bolts; however, it is not clear if the connecting rod bolts are torque to yield also. Does anyone know if the connecting rod bolts are reusable or do they have to be replaced?
What are the torque specifications for a Ford Mustang?

How big is the connecting rod bearing on a Ford?
One of the bearings was lose, just dropped out when he undid the bolts. The bearing itself was very slightly worn. No scratches, nicks…. just looked slightly worn. The crankshaft looks remarkably okay~ he cleaned the oil ports, bought an oversized bearing (I think 0.25MM) and it seemed really big.
How big are the bolts on a Ford Mustang?
Ford Engine Bolt Torque Chart Fastener Type Torque Spec Main cap bolts 95-105 ft-lbs Connecting rod bolts 40-45 ft-lbs. Cylinder head bolts 90-100 ft-lbs. Rocker arms 17-23 ft-lbs.
