Q

Which of the following would cause the dowel or locking lip of a split-type, precision insert, main bearing to shear and allow the bearing to rotate with the journal?

🔍 Key Concepts

• Bearing crush and how it keeps a split bearing from spinning • The function of the dowel / locking lip in a precision insert bearing • Effect of bolt torque (too little vs too much) on bearing cap clamping force

💭 Think About

• Which condition would most directly REDUCE the clamping force that holds the bearing shell tightly in the housing? • What has to happen physically for the bearing shell to be able to rotate with the journal instead of staying locked in place? • Among the choices, which is most likely to overload the small dowel or lip by making it carry loads it was NOT designed to carry?

✅ Before You Answer

• Verify which factor controls how tightly the bearing shell is squeezed between the cap and the housing (primary retention method). • Check which choice causes the greatest risk of the shell becoming loose in the bore, even before the dowel/lip is stressed. • Eliminate any options that mainly relate to temporary operating conditions (like brief speed changes) rather than the basic mechanical fit of the bearing.
