Re: Dill caps
 

I don't have that latest issue or any issue for that matter, about the weights being installed ONLY on back of wheels.. can someone enlighten me as to WHY this would be the case... why would the factory care, assuming it was done for aesthetics reasons?

Mike

Re: Dill caps
 

Because they would intefere with Trim rings mounted on the outside of the rim,if so inclined.

Rick

Was this "procedure" for all Bow-ties? or just Vettes? apply to spares too?

Thanks

Mike

Re: Dill caps
 

I can't say for sure Mike.
I do know they didn't know what wheel was going to be a spare,so they would treat them all as if they were going onto the actual car itself.
I have a few books & a 1967 Uniroyal 16mm 60 minute movie,that shows the wheels & tires being assembled & static balanced.
I really don't know if different plants did different procedures.

Re: Dill caps
 

Here is a short rundown of how one of the GM divisions did it (Oldsmobile) from Dave H, who was with Olds for a gabillion years...his thoughts were that each GM factory/division pretty much followed this procedure...

Factory balancing
All GM plants at that time used one weight to balance the wheel and tire assembly. Single plane, static balance. Hot wax was deposited in a color code to denote how much to put, and the tire was rotated and another yellow wax dot showed where to put it. You either got a 1/2 oz, 1 oz, 1 1/2 or 2 oz. Any more than that and the tire/wheel assy was rejected and replaced by another assy. Rejected ones were torn down and reassembled on another wheel/tire. Our main wheel and tire room at Oldsmobile Lansing ran at 600/hour in that time period, so that doesn't leave time to do split weighting like this tire/wheel. Some units were rebalanced with split weights in the audit area, so I guess I should never say never.

I think all the automakers used similar single plane equipment at that time (Micropoise, I believe), so my best guess is that is al old wheel/tire from a tire dealer. Toronadoes used dual plane dynamic balancing due to the huge offset in the wheel. That was done on another line.

My 68 came from the factory with Goodyear steel radials (an option on Cutlass, but not 442's) but they were defective and unsafe. Goodyear recalled all of them and gave a new set of anything you want just to get them off the road.

Re: Dill caps
 

Does anyone know what the color codes were for the wax?

Re: Dill caps
 

Yellow?

Re: Dill caps
 

Regarding the valve stem length discussed earlier,the normal short valve stem most tire stores use is called a TR413 or just 413 and is listed as 1 1/4 inches long in the dill catalog. From your description it sounds like the repro tires are coming with 418 valve stems which are listed as 2 inches long. There is a stem length in between the two called a 414 which is listed as 1 1/2 inches long but not all tire stores carry them. From the responces it sounds like some of you are on good terms with local tire stores and should be able to get them free or cheap. I usually sell them for .22 each but don't always have them on hand. Also I had my supplier get me a box of Dill 627 caps but it sounds like no one is going to need them now.I would be interested in how well the valve caps in an envelope go through the mail sorting machines.

Re: Valve caps
 

Thanks, Rick, but I was talking about the extension - not the stem itself. Most trim ring cars used an extension rather than the Dill 627. The part number is in the assy manual (which I don't have handy at the moment.

Re: Dill caps
 

Dennis:
Here's a poor pic of a correct weight. It is a Bada MICRO. The weight marking will be on both sides of "MICRO" ie: 1.5. A larger number ie: 43 must NOT be present. This is the weight in grams and indicates a later (80's?) weight. The weight will also have raised "wings" at the outer, upper edges. These are right for probably all 60's and early 70's Chev according to Gary S. Beaupre that wrote the NCRS article. The article is over three pages in the NCRS Corvette Restorer V31, No. 3, Winter 2005 (not the Driveline as I erroneously stated in a previous post). It is excellent and you really need to get a copy if you are nutty about this level of detail. I'll bring you a weight (if I remember) when I bug you about selling the LS6 at LaHarpe like I do every year.

These weights are a lot tougher to find than Dill 627 caps but they're out there mixed in with the old weights. Tire stores everywhere will be looking for restraining orders soon.......

Installation on the backside of the rim, only, is specified in Assembly Manuals and, as Rick pointed out, was done to prevent the weights from interferring with the trim ring clips if so equipped. The weight limit, I believe, was 5 oz - then the tire rejected. Weights are always grouped ie. never one at 2 o'clock and one at 5 o'clock.

Now, I understand, the major shows will be checking lug nut torque. It must be within 2 ft/lbs or you're out! https://www.yenko.net/ubbthreads/imag...mlins/haha.gif

Re: Dill caps
 

Here's a much better photo of a correct Bada MICRO weight. Per the NCRS article, this version has a "B" instead of the weight on the left and is also considered correct.

There are several other weights considered correct, as well, includeing those marked "OEM". Remember, though, no metric weights (grams) and no increments other than 1/2 oz per the Assy Manuals. Max single weight was 2.5 oz and any combination up to 5 oz.

Correct on the yellow. They used a red and a green to denote the amount, or any combination (2 red, 2 green, 1 of each). Don't recall what meant what.

Olds put all weights on the outside of the wheel, dealers were instructed to shift weight slightly (or move to inside) if interference with trim ring/wheel cover clips. These were put in the trunk and installed at the dealer. 3 oz was the max weight allowed in repair area, 2 oz in the automatic balancer in line.

Not sure if this was same at Chev and other divs, but guess that it was or very close.

Valve Stem Extensions - GM 9417745
 

Hi First Gen Camaro Experts -

I'm looking for the correct valve stem extensions for a 1968 base model standard Camaro with 14x6 factory rims. According to FAIM, the GM part number is 9417745. Can anyone confirm that is the correct part number and any info where I can find them these days? I need them for judging competition at the concourse level. Many thanks. Tommy

DILL 627 valve stem caps.

As mentioned above these caps were used everywhere.
The Schwinn factory used the 627 caps on the Stingray.
I have these on all my Survivors as shown on my ‘64 Super Deluxe below.

Pontiac used various length valve stem “extensions” according to the wheel disc usage.
Below is Pontiac information and MPC application.

My ‘65 GTO Survivor with it’s tire valve extensions for the wire wheel disc.
