Was looking for a shop in or near Milwaukee to work on M1008; then did it all myself!

I was going to tell you that but glad you figured it out for yourself. I know the horrors of finding the correct little fasteners when you get a CUCV that someone else tried changing that switch and had no clue. Not even a hint. I bought steering columns from any GM car of the era just for the correct fasteners. I lie. I removed the columns from vehicles that were at the crusher pile. Many times with a big yank of the loader fork thru the steering wheel. BAM. The column was out and all the little screws were still in place on the column housing. The wiring and steering column. Well they didn't make out so good. Many CUCV switches I removed were made by Singer sewing machine company. Does yours say Singer on it?

Yes the original switch was a singer. I tried messing with it to try and get it to start clicking again but it was toast.

The new balancer showed up today. Definitely looks way better than what was on there but it has a few marks/scratches on it and the rubber is a little wavy and wrinkly looking. How does it look to you guys? The guy I got it from said he purchased it from HPG. Is it maybe just old surplus and been sitting around for a while? Am I just tripping out? Should I put it on?

For what it is worth, the rubber looks uniform. Nothing "pooched" out between the two pieces of metal. I can't really tell if that is a crack in the rubber all the way around - or if it is just a compression mark where the rubber is doing its job. Had it been molded differently - with a round outside edge, it wouldn't have even been visible...

You are on the hunt for the "dry rot" look. That is something to be avoided at all costs!

Im about to install the new seal. Do I press it in dry? I know that I want to lube the rubber inner part but what about the outer ring of the seal where it meets the motor?

Sometimes it helps to have a thin film of RTV on it, but it will be slippery and IMO harder to install.
The red coating on the seal should "seal" it to the cover.

Most seals have coating on the outside diameter, so no lubricant required.

I always put just a little bit of oil on the end of the balancer part that touches the seal, during installation, just so it won't possibly tear the seal. Only one I didn't do that on was my 12v Cummins, since it had a special tool and specifically said not to, as it had some coating on it already.

Balancer looks fine.

 

[retro_life]

I took a page outta @chevymike ’s book and drilled a hole through my contraption and used the balancer installer through it. Pressed the seal right in! I guess the red coating around the seal is a Teflon and that acts as the lubricant/sealer when installing it. I just pushed it in dry and it seemed like it worked just fine.
now for the balancer should I rub some assembly lube on the crank shaft before I slip it on? Also should I use motor oil on the seal or is assembly lube ok for that also?
thanks guys!

Well boys, looks like we got a shiny new harmonic balancer installed! I ended up just using assembly lube in the inside of the balancer and on the crank shaft, and also on the rubber seal. Got it pressed on then installed the bolt and torqued it to 200ftLbs.
Also added just a hint of blue loctite.

 

[retro_life]

Just checked the cucv torque spec cheat sheet and didn’t see anything about the crank pulley bolts. How tight do you guys torque those?
Thanks, and sorry for being annoying just wanna do everything right.

just an excellent job, I can't say anything more

For bolts on anything that don't have a specific torque listed in a manual, you can use the standard for that size/grade bolt.

Do an image search for "bolt torque chart" and print one out for your size and grade bolts.

 

[Rutjes]

On a 6.5 with serpentine belt the crank pulley bolts are 30 ft lbs.

 

[chevymike]

I think I did 30-35 ft lbs with some locktite.

Nice job on seal and balancer install.

I just received my power steering bracket from @cucvrus and I am completely blown away by the quality of his repair. It looks like nothing ever happened to it! Wow man!
Here’s pics of it before

And here it is after his masterful repair job!


Thank you so much man! Also thanks for the proper hardware and other goodies. You are a real asset to this community and I can’t thank you enough.

Your a perfectionist. I like, good job. Those shocks look like original factory and the Steering damper also? Also while your at it replace the sway bar bushing, not looking so good.

I have a new kyb damper and also poly sway bar bushings, but no shocks yet. I’ll put them on after I get it running again.

Darn. Why did I think you were one step ahead of me!! Oh well, I'll try and find something else. You have gone viral on here. Not only have you acquired so much experience, but because of all your great pictures and information you are providing, you'll be helping other members for years to come . Thanks Man!!

I got everything reassembled and was fitting the belts when I realized that the Gates 7450 was way too tight for my power steering. (EDIT: read ahead, I was wrong. The 7450 fits fine.) There was a thread on here where someone went to Fort Brag and said he saw the proper belts for the M1008s there and listed 7450 for the power steering. It’s way too tight to fit at least on my truck. I’m going to take it back to the store and get the next size or two up. The Gates 7485 and 7575 fit just fine for the alternators.

Here’s the truck running. I currently don’t have the power steering belt on it but I figure it should be ok temporarily since the pump still gets spun from the generator belt. The motor seems to be much quieter but I still notice a little bit of a wobble down at the balancer/crank pulley. Or am I just tripping out? Like you said, I’m sort of a perfectionist snd things can drive me crazy.

My power steering pulley seems to be a little warped for sure, could that be what’s causing the wobbles? Or could it be my belt tension? Do my belts seem to be too loose?
