Fans are always driven the same direction of “suck” spin direction…so they always tighten. So clockwise rotation from the pulley tightens your fan while sucking air through, therefore clockwise rotation on the clutch fan removes it. Basically rotate it with an impact hammer same direction it spins while running.
Great video, definitely something that all 6bt or 4bt Cummins owners should check for piece of mind! Did the new crank seal shrink and seal up properly?
Were you working on road trucks or fleet trucks? How many years? How often does this happen? I am about to fly out of state and drive a 100K truck about 1000 miles home. I’m actually wondering if I should make this repair out of state before I make the drive. What do you think??
Question, could you use a small inspection camera put down the oil filler port to check and see if the dowel pin has been fixed so you don't have to tear it all apart? Thanks
Probably. If you could angle it the right way you should be able to see the pin. The problem with that is that most of the tiny timing cover bolts are loose and require tightening while you’re in there. And you won’t be able to check that with a camera. But if you’re only worried about the kdp then o would say yes it’s likely you could see it with a bore scope.
EASY fan removal technique. just use a hammer and long punch. put the punch on the corner of the fan nut and smack it a few times. or use an air hammer. easy peezy... just remember it has reverse threads!
When the engine is off the oil drains into the oil pan. There should only be a residue on the gears when you open it up. Especially if it hasn’t been started in awhile. This engine hadn’t been run in months
Thank you for your reply regarding NOT putting gasket maker on the front main seal The reason I asked was that many mechanics on You Tube routinely do use gasket maker for the seal. If your seal does not leak after two years, I would agree that the gasket maker is not required. Thanks again for your rapid reply. I have subscribed to your site.
@@redeyecafegarage7484 I guess it follows the old adage that if it isn’t broken or needs to be touched, then don’t?🤷♂️However glad that you knew about it before and corrected it before you completed the install. Did the seal compress and hold? Or did you have to replace it as well? Or will you make me wait until you post the next video to find out. 😂😂
