Idler Pulley Squeal
Posted: April 12, 2018, 4:33 pm
Not necessarily a 61-66 truck problem, but people here seem pretty knowledgeable and may be it will help someone with a transplant...
My 87 F150 w/300 (EFI, Serpentine belt, A/C, smog pump, power steering) is having a bad belt squeal issue. I recently did some power steering work, bled the system, and put a new Motorcraft idler pulley and Motorcraft belt on. By process of elimination (the 'ol WD-40 spray and see what stops squealing) I've determined the new idler pulley is the culprit. I spray it and the engine runs nice and quiet.
Is the pulley something I can grease? Maybe I got a defective one or maybe the "new" ones aren't quite right? Anyone out there run into this issue and have some guidance?
