A tilted or improperly sized oil standpipe can allow oil to migrate upward along the pipe’s wall when the motor is in operation, leading to leakage, loss of lubrication and potential bearing damage. This issue can be overlooked during assembly or inspection, but a few simple checks can prevent costly problems.
