Where to get Flywheel for 6.2 Cucv

[biped]

My truck eats a starter about every 3 years. The mechanic who installed the last starter says the flywheel is part of the problem. I'm not seeing a replacement flywheel on-line so I thought I ask if someone on the forum can point me in the right direction. The truck has been bomb-proof in every other way. New glow plugs made a huge difference this winter.

It's the same as any 6.2 with a th400. If your store doesn't list a D30 Chevy order one for a civy model. Most napas have the d30 in the system

I would guess the pinion clearance is not being checked. I'm guilty just as anyone else for not measuring it. Stick whatever shim that was in there.

But if it's "eating" starters this would be the first thing I look at.

Thanks guys. I'll be checking pinion clearance. I'm on phone with Napa tomorrow.

I didn’t read all of the replies - but - my experience was that the starter must be properly shimmed. Also, we were getting poor quality flex plates through the Army supply system. Our solution was to local purchase heavy duty flex plates at our local GM dealer.

It will probably be a vicious cycle until you replace both the flexpalte and starter at the same time, making sure to get the starter shimmed correctly.

FWIW, Autozone shows the flex plate available in a couple of options for a 86 c30 with a 6.2 I'm guessing you need the fra-142 maybe. Next day delivery for me here.

I had a CUCV starter let me down years ago 3 hours from home in zero degree temps at sundown. I had to hitch a ride buy tools and pick up a starter. Changed it in my clients parking lot, only to find out the new starter was bad too. Another hitched ride to buy the last starter in town 2 minutes before the parts store closed at 10pm, and swapped in the second starter while wondering if I was going to freeze to death. Finally got it working around midnight. Good times.

So, I bought the flex plate and the starter. Do you know the torque spec's for the flex plate? The transfer case takes the same fluid as the transmission, right?

Sorry, I'm not much help there. I owned all of my CUCVs long before I owned a torque wrench. If it's not in the TM, I'd figure it the same as the civvy 6.2. Hopefully someone else will chime in for you.

14077157 is the GM part number per -34 TM. 65 ft-lbs is the torque specification.

Thanks. The flywheel is installed. Next we put transfer case back and oil pan, starter. Fixed the main seal leak too. So, now I've a 36 year old 6.2 that should last a while longer. Engine oil cooler lines remain a puzzle. Everybody says they leak and you can't find replacements that don't leak too.

Thanks for you help.

The oil cooler lines on my 1031 have leaked near the sampling port ( coolant overflow reservoir) since I've owned it. I have used every durometer Viton oring available, they last for a few months. Only real solution is to replace with AN fittings..I might do this after I swap head gaskets and install the altitude compensators. 8500 pounds needs more motivation than 155 ponies. I measured 0.005" additional stroke possible on the injection pump so 205 Hp is possible. Just need another 10 PSI of air in the intake manifold.
