Engine/Drivetrain / Re: Missing Cover?

« Last post by KamperBob on June 02, 2024, 11:37:02 PM »

Thanks y'all. Looking again at pix for p/n 3843943 the bolt pattern looks wrong. Maybe this week I can try some junkyards. Meanwhile I'm underneath to replace motor mounts which is feeling like its own a slippery slope. Trying to find a jack point to lift the motor from below. That's harshed by the front axle and frame cross member in the way. While under there I can try whittling a cardboard template prototype cover with bolt holes marked and approximate shape. The idea being to either take with to junkyards looking for a match or transfer that shape to sheet metal to make a cover.

We ran a C30 for 10 years without one and it didn't hurt anything. But I'm like you at this point and would want it on there. Facebook Marketplace parts trucks and eBay are probably your best bet. I'm in Oklahoma and there aren't many k-30s around this state so I've never seen one in a salvage yard. But if you're in a state or area where they are more common you might look for it there as well.

A local salvage yard or internet search can easily find you the part. Bell Housing dust cover!

It is a dust cover and goes by other names as well. Every lazy mechanic rips them off and doesn't bother to put it back on, even though it's just a few more bolts. Can't help you sizing options on the internet though. Might try Ebay too.

Edit: Looking at your links above the Classic Industries one probably doesn't fit SM465. The Summit and Amazon links look possible.

Further exam made clear it wraps around the lower half of the bell housing behind the oil pan. I found some leads calling it a bell or clutch housing dust cover. This one indicates match for Saginaw and Muncie transmissions.

BUT others like this one say the 3843943 is for earlier model year applications and only 11" clutch.

According to the GM specs literature I found it's a 12" clutch. Maybe the same cover, maybe not.

This one says: Will NOT work with 11" GM Truck bellhousing.

Engine/Drivetrain / Missing Cover?

I'm restoring an 84 k30 with 6.2 diesel and SM465. Seems like a cover is missing just below the starter. As is road crud has an easy in. I might could fashion something but can anyone help me source the proper replacement part? TIA

That's what I meant, my distributor was mounted this way and I always struggled with the screw nearest the firewall but after fitting it as I said the 2 back screws are both easily accessible. Just saying.

Transfer Cases and Front Drivelines / Re: NP 203 rear yoke nut

😂 I tested my old one by hand threading it on and the "locking" portion of the threads showed no resistance. I was able to run the nut snug against the spacer by hand, that shows me it's no good.


I ordered the nut from the eBay ad linked, thanks for the help guys!

Yep, it is rotated a little further clockwise than because it is loose and the hold down is not on. I'm making sure the ignition wires have enough play when rotating the distributor back and forth for tuning. I will remove it prior to putting the engine in my truck to make it easier and prevent damage.

The distributor cap connector is on the drivers side and #1 is pointed toward that direction @ TDC. Same way it was mounted on my last engine without trouble.
