Title: Chevrolet Dealer Technical Service Bulletins for 1969
Post by: rich69rs on August 11, 2007, 07:20:05 PM
While at the swap meet this week at Hot August Nights in Reno, NV I scored some Chevrolet Service News and Chevrolet Dealer Product Campaign Bulletins for model year 1969.  The Service News documents completes my set for 1969 and goes most of the way through 1970.  The Dealer Campaign Bulletins instruct dealers as to how to address known quality issues with customers via various "campaigns".  Each of these bulletins also include the form letter that the dealer was to use when notifying a customer of an "issue".  Those two finds were good enough in and of themselves. . . .

However, what was really a find was what appears to be a complete set of the Chevrolet Dealer Techinal Service Bulletins for 1969 which give instructions to the dealers as to how to fix problems reported back to Chevy by customers after purchasing cars.  Some of the items of interest include:

- Low Fuel Economy
- If requested by the customer, procedure for removal of head restraints prior to midnight 1/1/1969
- Wind Noise issues with ventless window glass
- A/C Hose Rupture - 1968 Camaro (includes instructions for core support seal strips)
- Changeover from Chambered Exhaust to Dual (interim) to Dual with Resonators (final solution) for Z/28
- Possible incorrect wiring of low fuel warning light / cars with gages prior to VIN #'s N517033 and L504760
- Hard Hot Cranking / 350 cid 300 HP engines
- Spedometer Errors
- Door Lock Binding / 2 Door Coupes
- Battery Trickle Drain especially on Stored Vehicles
- Fuel Line "Ticking" Type Noise on cars with 2 fuel lines
- Hesitation on Accleration / 327 and 396 engines w/2Bbl Carbs
- Crankshaft Pulley Cracking 307/ 327/ 350 engines with A/C
- Brake Moan with car moving in reverse, Camaro and Nova with Drum Brakes
- A/C Hose Damage 69 Camaro with V8 engines
- Spedometer cable oil leakage at the transmission

These are the topics out of the total that seem to have the most relevance to 69 Camaros.  I have scanned all of these document and will post them if I can get the file sizes small enough.  Currently they are all in PDF format and at least 1 MB in size.  Hopefully a conversion to JPEG will allow for file size reduction with still adequate resolution.

Tech Service Bulletin for 1969 Potential Overheating in 396 and 427 Engines - Page 1 of 2.

In previous threads and discussions, others (in particular JohnZ) have pointed out the benefit of using intake manifold vacuum instead of ported carburetor vacuum as the source for the distributor vacuum advance.  One issue with lack of proper vacuum advance, is the potential for the engine to run hot at idle or in city traffic.  Refer to the following for JohnZ's disccussion:  http://www.camaros.org/forum/index.php?topic=64.0

In this Tech Service Bulletin, you will note that the bulletin states that:  "Full vacuum advance at idle must be provided".  On the second page, the drawing shows one of many possible ways to do this.  The service bulletin is telling us the same thing that JohnZ has pointed out.  Full manifold vacuum as the source for the distributor vacuum advance is a desirable thing.

Wow that's a very cool find Richard, thank you very much for the information. I read the hot starter SB with quite some interest as my 69 350 does this. Mine is a late 69 production so I would assume that it was built with the 1108420 starter as the SB is dated late 68. Makes me wonder if there wasn't another SB to come out at a later date replacing this one.
