LS 5.3 (LM7) Harmonic Balancer Install 

Been watching your build series for awhile brother Im only 17 and went through 5 trucks before i found my 81 blazer project. Your videos keep me motivated on the build thanks

Great video. Was looking everywhere for an answer on alignment.

So if the old TTY bolt can handle the 240 ft lbs without breaking, why not just re-use it if you're risking it anyway? Doesn't make sense.

Enjoyed the lack of options..just facts..thanks for that

my oil press needle went down to 0 twice on an 18 mi trip last week morn in the rain. Did a U turn back to home approx 5 mi out. heated balancer core on bottom with propane. Finally got long OEM bolt to loosen with a combination of electric impact and larger weight hammer on the breaker bar with 6 point socket. With Snap-On 2-jaw puller w/ long jaws attached, some more hammering required (lefty loosey on the OEM bolt and righty tighty on the puller. progress was incrementally GRADUAL. Any way I came here regarding the two sight holes in the balancer and was wondering what kind of timing lights you all use on these newer Chevy motors? I installed a new stock Melling pump. Same brand i used to get in the engine kits in the good old days. I guess I have to go buy that longer install-bolt from GM dealer. LS1 Balancer-Bolt. I'm never gonna get 240 ft lb , 37ft lbs and 140 degree-twist inside a chevy express engine compartment. Thanks 3rd Gen C10's for the crankshaft to pulley key-way orientation-information.

Can use the stop plate tool with the motor and trans mounted? Great video!!!

Have you got it running yet I'm about to do my harmonic balancer and debating if I want to put it in then out timing cover but I already have timing cover on did you have any leaks putting cover on first

How did you keep the engine from turning while tightening/loosening the bolt?

Instructions that came in a Dorman replacement says to mark the old one in reference to the holes along the outer ring. My problem is I don't have the original to go by. And no lube on seal or seal surface??

Why not just live the old one at 240? Why you have to take it out

This video helped a bunch

Thanks for video

Can you not reuse the original stud that was holding the balancer in place, or is it just good practice to reinstall an brand new stud, I have never done this before 1st atempt just trying to get some guidance. Thanks .

Good video helped me out

The harmonic need aline with something especially?

What lubricant did you use on the installer bolt? High temp grease?

How would you do this if you were using the oem torque to yield bolts? What do those torque down to?

Awesome video. When I was getting my 5.3 back together a couple of years back my nephew, Captain Caveman showed up about that time and before I could stop him the gorilla picked up my impact and bolted my balancer back in place with it in about 3 seconds. He's not one to be slowed down by unnecessary proper techniques. Bull in a china shop. No damage done to my knowledge but I sure was pissed. I'll know for sure when I take it back off soon to install my new high volume Melling oil pump. Where did you source the all thread you used and what was the length etc? If that's in the links provided my apologies. I will check them out too.

Nice instructions

Great video !!

Dang, I don’t currently have a torque wrench that goes up that high. Have you seen the sloppy uploads where he heats it up and just pushes it on?

Good video 👍

I installed mine and it it supposed to be in timing??

What size all thread did you use where did you find it

All instructions say do not lube seal, so why you lube it?

What is correct torque for 5,7 ram 1500 ? Thanks

How did stop crank pulley from spinning while torque bolt down?

What your intake manifold and carb setup?
