We remain on the same path.....my harmonic balancer has been ordered from Amazon but still not shipped two days later, not sure what's up with that........and then transmission and transfer case mounts will be addressed.......then I'll take to a shop for evaluation of my ATF leak, either from transmission and/or transfer case.......other than these "little" problems truck runs/drives fine.....I think!

One of the transmission mounts had been scavenged by the CUCV mechanics. They also took the other half mounting bolt. 1984 and older vehicles have the 2 piece Transmission mounts. I picked up a set from NAPA and sourced some new 1/2"x 3-1/2" Grade 8 bolts. I also picked up some grade 8 washers and locking washers. These are COURSE thread as the screw up into cast iron. Now my transmission is fastened properly in place. The old remaining mount was pretty dried up and thrown away. I still have a slight vibration at low idle. Going to install a new Harmonic balancer next.

You may want to consider a Fluidampr instead of the standard Harmonic balancer.
After I installed the fluidampr I seriously thought I had broke something. Everything was
so incredibly smooth. There is a world of difference in the felt vibration between the two devices.
Just my 2 cents. There is a reason why most race cars use the Fluidampr.

$100 ACDelco vs $400+ Fluid one.

Easy decision for me

I agree the fluid ones are very nice. I just couldn't justify the extra $300

Same for me

I had to cancel my Amazon order for the harmonic balancer - they couldn't ship what they didn't have......trying to source one through another supplier

richingalveston · Apr 13, 2017

I have one I pulled from my 6.5 gep to put a fluid dampner on. I believe they are the same. It is the same as the one that I have for my 6.2 or at least looks that way, side by side I cannot see any difference.

IF it works, $20 plus shipping but I won't be home until sunday night.

Most auto parts stores can get the balancer next day.

pm me if you want it.

Rich

I see you are in Houston. I will be in greenspoint area working a job on Monday if that is close to you maybe we can meet at lunch

Did they say they are out?
I just checked and it is still showing in stock.

If you choose the free shipping, it sometimes takes a bit to get to your door.
Local parts store should be able to get it for you.
They only stock the cheap ones.

Buying a used one isn't any better than leaving old one on.

If your going to the trouble to change it and the seal, install brand new.

richingalveston · Apr 13, 2017

the one I have is brand new, it came from my new gep 6.5. pulled if for fluid dampner.

was installed but never ran on engine.

BradL84D30M1008 · Apr 13, 2017

I should have a shipping notice shortly for my alternate source.......when I spoke with Amazon this morning they were indicating the part was on back-order.

If you are leaking atf, you must replace the seals in the transfer case and transmission.

BradL84D30M1008 · Apr 19, 2017

I'll be replacing motor mounts and transfer case mounts (ordered from ORD) along with the harmonic balancer to first make stationary my drive train, and then yes on to replacing seals for transmission and transfer case, which were no doubt negatively affected by drive train vibration.

ChevyNationParts was a quick shipper for my OEM harmonic balancer.

Post pics of your old balancer if you would.
Mine looked ok while it was on, but once it was removed, was way worse than expected.

BradL84D30M1008 · Apr 21, 2017

Will do.......thinking this will be a journey to correct/improve several things on my unit, so will take before/after pics to document.

Not sure what "worse than expected" looks like, but see below for pics of my old harmonic balancer.....doesn't look good to me.

It definitely needed replaced.
Looks way past due.

Hope you replaced the seal while it was off.

A suggestion, if I may, another GM "weakness" is the rear drive shaft. If you are going for a bulletproof expedition rig, change the transfer case output to the flange style and have a shaft made with the slip-joint in the shaft. Two purposes : 1- If the rear shaft or any part of it (u-joint) breaks, drop it out and go front wheel drive (yes it works, even better with a traction aid in the front pumpkin) when out in the weeds. 2 - makes the trans / t-case a sealed unit. If the factory shaft falls out, the juice is loose and you are stuck. Everything else that I read sounds right-on.

Another unrelated tip : If the glow plug system craps out the key to starting is to floor the throttle and crank away ( within the duty cycle of the starter motor ) If the engine is right ( no tight valves, excessive blow-by, etc. ) she'll fire ( the colder the outside air temp., the longer the crank time needed ). The glow plugs are there to "help" it start quickly by preheating the air going in. It WILL start and run without any of it. Just make sure that after it does start that you run it at "normal operating temp" for a while to evaporate any fuel that might have "polluted" the lube oil.

Offered tip because it can be difficult to find a GM dealer or NAPA store in the Amazon Basin. We, however, are only a post or PM away. :beer:

Had a local mechanic do this for me......also replaced oil pan gasket in the course of this work......I'll ask about seal for harmonic balancer.

Thanks for the tip......was thinking along the lines of evaluating a swap of the NP 208 for an NP205.....will think about this.

Any new updates WARWAG?

WARWAG · Aug 27, 2018

Sorry I have been gone for so long. My work has kept me out in the field way to much. The Campulance is just about done. The drive train is pretty much done. I installed Toyo Mts 255/85R16 tires. The Toyos are the nicest tires I have ever put on an off road vehicle. They totally change the ride, sound and feel of my truck. They are my new standard load out for any vehicle I own. They are that good. The rear cabin has been cleared out and is ready to receive its new interior. The cab is in need of a new dash and a few small things. Vintage Air will take over the A/C works sometime later. ORD Lift has arrived. Will work on that when I get home. Banks Turbo will round everything out.
