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?
Do you have to torque your rod bolts?
Torqueing your rod bolts without pre-determining the required torque to achieve the correct rod bolt stretch is not recommended. However if this is the only tightening method available to you, DO NOT EXCEED THE TORQUE AMOUNT INDICATED FOR YOUR BOLTS. NOTE: Your Crowerods are totally rebuildable.
How are torque and play Calculated for spherical bearings?
Not only for swaged types, but also for other spherical bearings, certain torque and play values are required: no-load breakaway torque for PTFE lined bearings, and both radial and axial play for metal/metal bearings. The no load breakaway is measured by fixing the ball aligned with the axis of a torque meter.
How much torque do you need for PTFE bearings?
Standard torque requirement of PTFE type bearings is 0.049~1.96N · m {0.5~20kgf · cm}, which is relatively high comparing with ball bearings. Although it is possible to manufacture PTFE type bearings with 0.02N · m {0.2kgf · cm} or less torque, it should allow approx. 0.05mm play as well.

What should the torque be on a 90° turn?
◦ 90° torque turn. The end play specification is 0.099 to 0.419 mm (0.0039 to 0.0165 in.). Insufficient end play can be the result of a misaligned No. 6 main bearing, a misaligned upper thrust washer or debris on the inner face of one or more of the thrust washers. Correct the end play, if necessary.
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 are torque to yield bolts supposed to be replaced?

What is con rod bearing?
Do you know the function of con rod bearing? (1) Poor lubrication or too small bearing clearance, causing the bearing alloy to burn out. (2) The quality of the con rod bearing itself is defective, and the alloy falls off. (3) The connecting rod journal is out of round, which reduces the contact surface between the journal and the con rod bearing, causing early loss.

What is bearing of bolts?
A cross-bolted bearing is a bearing, usually a crankshaft main bearing of a piston engine. Most bearing caps are retained by two bolts, one on each side of the bearing journal, and parallel to the cylinder axis (or, on vee engines, parallel to an axis bisecting the vee angle).
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.
