Harmonic Balancer Snapped

-Under the Oil Pump Cover…..

As I said, I’m no mechanic and am very unfamiliar with the woodruff key……..
so any geared-down guidance for a JV would be great. Ha!

 

need to make sure that key is good and tight...solid square in the slot

otherwise it'll just twist and destroy the new HB


cant tell from your pic.....but might be a little twisted

 

Gotcha, thanks! About to go dive back into that right now.

 

Didn’t mean to go silent for this long. Had a bunch of things unexpectedly come up this last month………….

Was just able to get the timing cover off……..I’m screwed, aren’t I?…………

 

Yep....I had similar 6 yrs ago

it was an easy fix......well except for the $5000 hole in my pocket it left...



If that key can lean....you will eventually spin the next HB...

on mine the A/C kicked on.....and put it over the edge



Its really import to seat the new HB carefully\\
with being such a tight fit....its a recipe for disaster

polish and lube the snout.....and file the edges of the new HB's keyway...
so it doesn't stick the landing

its moved so much on yours.....its busted that timing gear
its thinnest part is on that key slot

your picture is not very clear......need better one

 

Key has to fit snug.....

 

I figured………….was just hoping I was wrong…………Here’s some more pics of it.





Didn’t realize I took such poor pictures ha……….I’ll snap a better one when I get home.

 

The $5K question is......did that gear get broke from key kicked up and caught by the HB when it was mounted....

or did it break from key rocking


in earlier pic it looked twisted




IF you tap that key back in......does it fit snug/tight


Also you need to check the back of the timing cover and look for hairline cracks on the back side of the oil pump gear area..........a wobbling of HB is really bad inside that

 

This is where an overall truck evaluation is required. 2.4's are pretty rare to get used and having said that I bet 3 will pop up in google searches, anyway, if the truck is in good shape it might be worth the effort otherwise sell her and let someone else do the project. With the proper tools you could start this on a friday afternoon and be driving her sunday afternoon.
