How to Install Harmonic Balancer – Envoy/Trailblazer. I finally got the engine put back together and it’s running smooth. In this video I show how I installed the harmonic balancer on my 2004 GMC Envoy with a homemade installer tool.
After an initial diagnosis of low oil pressure with a manual pressure gauge in my 2004 GMC Envoy (~255,000 miles), I decided to investigate the oil pickup tube. Come to find out, it was about 90% clogged! This is how I fixed it.

I like that!
How did you hold crank in place while torc ?
How much tension should the chain have? How much play is the limit?
the engine sounds great.
Thanks for writing back. I went on graingers website and they dont list the thread of bolt.
Last question do you wanna sell one of those tools. Or can you tell me the part number for the kent moore tool. Thanks again
What's the size of the crankshaft bolt
Kevin nadeau Could you share the link of the harmonic balancer install tool please I've been looking for it and I don't know what it is, a lot of different measures come out
in the description it says that it is compatible with ls lsx ls1 ls2 ls3 ls4 ls5 and lq9 en gine i home you can help me.
how do I hold the flywheel with the torque converter still installed?
Kevin, have you noticed any leaks from the front crank seal? The reason I ask is the GM Service Manual says to install the Friction Washer between the front cover and the crank sprocket.
Are you suppose to line up the oil pump a certain way when you put the timing cover back on?
