Harmonic Balancer Bolt Removal



246 -rear head
135 -front head

(looking at the engine, from the front, like if you opened the hood)

i got that **** memorized from doing spark plugs all the fuggin time lol
 
Final thought, when putting all this back together I didnt think about putting on any lock tite or anything on the balancer bolt. I just impacted it back on. Should I pull it again and put some sort of lock tite on it?
 


GM ACDelco - Crankshaft Bolt #GM-24504736

If you used a new TTY bolt
: 111 ft/lbs + 76 degrees angle torque up to 10/98
111 ft/lbs +114 degrees angle torque 10/98 and up

If you reused the old bolt just torque it to 111 ft/lbs because it has already been stretched. Put some moly grease on the friction surfaces. That's what I did on my last rebuild and no problems yet.
 
I've never put locktite on the HB bolt, and I reuse the stock bolt all the time.

After putting the balancer on by hand and getting it to engage the key in the keyway, I zip that bolt on with my impact. Never an issue..never a worry.
 
Hi Guys, I'm getting ready to do a crank position sensor job on a 3.8.

Could someone describe to me how to lock the flexplate to hold the crank still while loosening/tightening the harmonic balancer bolt? Thanks!

(side note, I too have used the "redneck method" for loosening the bolt on a hyundai, but I don't have a good method for tightening the bolt, which is why I'd like to know more about this flexplate method...thanks!)
 


Thanks Matt! I got it, that's an awesome tip, makes life so much easier! (to clarify the inspection cover is a plastic over just rearward of the starter).
