When installing the bearing cap on the device shown in the illustration, which of the precautions listed must be observed? Illustration MO-0121
AI Explanation
The correct answer is D) Once the bearing cap is properly torqued, measure the end gap dimensions to ascertain even tightening of the cap.
This is the correct answer because it is important to verify that the bearing cap has been evenly tightened to the appropriate torque specification. Measuring the end gap dimensions allows you to confirm that the cap has been installed correctly and will properly support the bearings.
The other options are incorrect because: A) Positioning the thrust shoes is not directly related to installing the bearing cap; B) Reassembling a contaminated unit would not be a proper precaution; and C) Torquing one side at a time is not necessary, as the cap should be tightened evenly all the way around.
