C2 zerk fittings

[Richard S.]

I would appreciate information on the correct grease fittings for the front upper and lower ball joints and any others on the C2 (63 early vett) where the information might be available.

Richard, the 63/64 JM has a picture of the correct fitting and the position ot fitting. early cars have a 90 degree adapters with the fitting facing forward on both upper and lowers.

Thank you for that information. Do you know if clutch shaft and universals had grease fittings or plugs? I just don't remember. I have had this car since early 65. But, over time and parts replacements I have forgotten what was original.
Thanks

Re: C2 zert fittings

There is a zert on the 'Z" bar for the clutch.
None of the u-joints had grease fittings (drive line or 1/2 shafts).

I used an outdated manual for my rebuild. Bad idea, be sure to purchase the latest manual from NCRS for $50 + shipping.
If you plan on showing your car get the window sticker at the same time.

The sticker is difficult to find, look under;

I failed to find it as i was searching for window sticker. Silly me.

Re: C2 zert fittings

I prefer these for the half shafts as they are the closest joints, I could find, to the originals.

Genuine GM OEM Rear Axle *(Half Shaft) Universal Joint 12522048, 12471503, 1247230, 88964507.



The SKF joints are stronger but they also have blue boots and a zert fitting.

I don't know of a modern car that has a zerts on the drive line, although I am sure their are exceptions.
The seals have been improved and so has the grease. Just not necessary anymore.
That said, I believe, back in the 60's leaving zerts off was a cost savings measure.
I have seen modern Jeeps without the ability to change the joint. You have to purchase the complete drive line.
Just what one would expect on a jeep of all vehicles! A cost step too far in my book as the drive line was $800.

Re: C2 zert fittings

Hello Rick
Thanks for those part numbers. I believe I purchased my universal joints from either Chicago or LIC a few years ago. They are fine I happened to be under my car checking things over and noticed I had grease fittings in the joints so I greased them. But then I was not sure what the originals had looked like, so my original questions. I like having spare parts. So the part details are greatly appreciated. For the few miles I put on my car I guess it would not matter. Nice there are NCRS members like yourself that maintain a trove of vett car details.
Thanks again
Rich

I thought the cars were delivered with a red plug in the 'Z' bar and the Zerk was added during its first service.

Re: C2 zert fittings

Jim;
Good point.
As the question pertained to a early 63 it would be correct to have the zert installed.
In 64 plastic plug was used instead.
I suspect this, plastic plug, setup continued through to the end of C2 production but haven't confirmed this.

When ever my car is jacked up I check the half shafts retaining bolt torque.
They are critical for the wheels to stay put! And on 63's no locking tabs were used.
Just a good safety check.
Whenever I am under a vehicle I look at the suspension to see how it's designed.
I have never seen another design that retains the wheel with the axle.
If their is one it would likely be an old design as the lawyers would have a heyday.

Thank you, I didn't know about 63's not having the plastic plug.

Arland,

Good point. The Zerk fitting is named after Oscar Zerk, from a patent in the 1920s. For future searches of the DB archives, it would be good to use the correct Zerk spelling.
