Pulmore /truck noise

NycfanOGR Forum Member

I have a F3 powered B unit with pulmor motors of which one squeals while running.Unit does not buck but just squeals despite proper lubrication of worm gear ,truck gears and axles.Could this be from motor or the truck gears?

Usually it’s the lower motor bearing that gets to squealing like a pig, ….the only fix is to pull the motor out of the truck, and properly lubricate that lower bearing. There’s not a whole lot of moving parts in that truck & motor, so it’s pretty simple to do, ….clean & lube everything in sight while you’ve got it knocked apart,….
