Decoding/Numbers / Re: Eight track tape player

« on: July 23, 2009, 06:57:21 PM »

Its a later model, post 1969.  The highest delco number for any unit, radio, or 8 track player, starts with a 73xxxxx in 1969.  There were different units for multiplex or non multiplex systems.  There were 2 knob non multiplex units that mounted under the glove box, and 4 knob units, both multiplex and non multiplex that mouned on the top of the center console, and a non multiplex 4 knob unit that mounted on the floor in 67 if you didn't have a console.

That book would contain the engineering part numbers just like the AIMs have.  That is the only place you will find those numbers.  Service part numbers in the parts manual may or may not represent the same part that was put on by the factory.  It could be an identical part, or it could be a functional equivalent part.

None of them do that.

You need to understand the GM part numbering systems to see whats going on.  The part numbers in the Assembly manuals are engineering part numbers, and these may represent a single component, or an assembly of components.  The center link assembly in UPC 4 (I think) is a good example.  It is a single part number for an assembly of the center link, inner and outer tie rod ends, the tie rod, and the idler arm.  These numbers are not the same as used in all the Service part catalogs.  When a new component or vehicle is added to the GM "system"  The Parts department decides if they are going to carry that exact part, or if an existing part number will "serve the purpose".  If they need to carry a new part a service part number is assigned and that part get added to the parts manual.  Initially GM added alot of new parts to the parts catalogs when new vehicles were introduced into the system, but over time these parts get reduced down by functionally similar parts and number change, get supperceded or just plain deleted.

Springs are another example of parts getting consolidated.  In early 69 there were probably 20 different front springs you could get on a Camaro from the factory, plus those used on the earlier 67 and 68 cars.  The parts catalog from Sept of 69 carried about half that many and consolidated many applications that were close into single part numbers. By 1972 there was only about 5 springs that were listed in the parts manuals.

Part numbers on service parts for the most part have no bearing on the part numbers the original engineered item may have cast or stamped into them.  If you buy an "NOS" 69 trim ring for an SS based on a part number on a 1980 GM box, you may be buying a consolidated part that originally was made for a 1975 Nova.  It will fit on the wheel, but the profile, or the shape of the valve stem hole probably won't be the same as what was on the car the day it rolled off the assembly line.

Get the date off your rear axle.  The rectangular radius arm did not come into being until Late march or early April of 67, and was used on the higher HP cars.  Doubt that that is the original axle for the car.  There was a retro fit kit available to address wheep hop problems but it is different than a factory installed unit.  If the front support plate is bolted into the car, instead of welded you may have one of those units.

« on: July 18, 2009, 01:20:24 PM »

If both of your guages are not working its most likely that you don't have the console cluster grounded.  Make sure there is a black wire running from one of the metal back panels to a ground point on the floor under the console and another connecting both metal back panels together.

Been about a year since Musclecar Review printed the 53 03C cars were painted in enamel.  Testing was supposed to have been setup with PPG on some original panels, yet nothing new has come up.  Anyone know how the tseting is going, or went?

Did you swap the pivot point for the brake pedal?  There are two holes in the arm for the brake pedal, drum brakes use one, discs use the other?

Probably bent the float arm that the sensor works off of either taking it out and putting it back into the tank so now its off by a little bit.

« on: June 16, 2009, 04:12:04 PM »

Rear panel blackout, stripes and rocker trim black out on style trim cars was done in the in line repair booth after the car had been painted and firewall had been blacked out in the blackout booth at the end of the paint shop.  How many colors of black did they have in the repair booth, a gloss for the stripes and rocker panel blackout (never heard anyone question the gloss level here) and a semigloss for the tail panel?

The May built ones were probably pilot cars, built off line at Norwood, remember they were still building chevy IIs (Novas) at Norwood in May of 66, and it probably didn't have a VIN assigned to it at the time of its actual build.  Obviously there are at least 13 of these pilot cars out there with way early assembly dates, some of them may have been held around and released for sale when actual production started in late August of 66 and the VIN was assigned at the point the decision was made to make it available to the puiblic.

Body numbers are not in numeric order on a day to day basis, they do generally increase with the VINs.  GM sent Fisher orders for cars based on availbility of partsand orderes on hand.  These orders were assigned the Fisher body number at that point, but Fisher was free to produce them in any order that made sence to them, like grouping of one color car together therefore the body numbers get shuffled around within each days production.  The 860 body number car might have been pulled forward by the Fisher scheduler (GM scheduled 912 cars a day thru Norwood) because there was a batch of gold cars (860 is a gold car) being painted first that day, and it just happened to be the first body that made it to GM that day and it got the VIN 100001 assigned when it got there.

Originality / Re: Original Paint used for Undercarriage

« on: June 09, 2009, 04:02:34 PM »

Its primer only, could be red, black, or grey depending on where and when the car was built.  Any body color on the undercarriage is overspray from painting the rocker area.

Been repainted.  Wipers were not installed when the cowl was striped.  GM  (or at least other GMAD workers further down the same line at LA) installed those about a day after the cowl was painted.

Wow, the factory did a highly accurate job of taping off that bottom line, must be off by an inch over the wdth of the car.

Maintenance / Re: Console Temp guage

« on: May 31, 2009, 03:25:13 AM »

All 4 terminals will have 12V on them when the guage has power.  Resistor goes verticle (horizontal on fuel gauge).  Pink wire connects to two coils inside the guage, one coil connects between pink and green wires and is grounded thru the temperature sender.  That coil moves the guage upscale towards hot.  Second coil connects between the pink wire and the top terminal, then it runs thru the 86 ohm resistor to ground at the bottom terminal.  This coil moves the gauge downscale towards cold.  Gauge that goes hot and does not return to cold indicates a bad ground on the back of the gauge, a guage that never moves off cold indicates an open in the temperature sender circuit.  could be anywhere from the pink wire terminal to the sender itself.  Measure the coil resistance from the power terminal to the green terminal and from the power terminal to the top terminal  make sure neither is open circuited, also make sure neither is shorted to the case (although if they were you should blow your instrument panel fuse).
