The 1969 Porsche 912 is a classic that shares much of its DNA with the iconic 911 but with a lighter, more affordable punch. Restoring or maintaining one requires accurate parts sourcing, and the official Porsche Electronic Parts Catalog (PET) is an indispensable tool. This guide explains what the PET is, how to navigate it for your 1969 912, and how to use the information to find the right parts.
What Is the Porsche Electronic Parts Catalog (PET)?
The PET is Porsche’s official digital parts catalog, originally released on CD-ROM and now available online through various channels. It contains detailed exploded diagrams, part numbers, and descriptions for every Porsche model from the 356 through the 997 generation. For the 1969 912, the PET includes every nut, bolt, gasket, and panel, making it the definitive reference for restoration and repair.
Why Use the PET for a 1969 912?
Before the PET, mechanics relied on printed parts catalogs that were often outdated or incomplete. The PET provides:
- Exact Part Numbers: Avoid ordering the wrong component by matching the number from the diagram.
- Exploded Views: See how parts fit together, which is invaluable during disassembly and reassembly.
- Supersession Information: Porsche often updates part numbers; the PET shows current replacements.
- Model-Specific Variations: The 1969 912 had unique features compared to earlier years, such as revised engine mounts and electrical components.
How to Access the PET for the 1969 912
Originally, the PET was a dealer-only tool, but enthusiasts now have several ways to access it:
Online PET Versions
Several independent websites host scanned or emulated versions of the PET. Search for “Porsche PET online” and look for sites that offer model-specific navigation. Some require a small subscription, while others are free but slower. Always verify the accuracy of the data against official sources.
Porsche Classic Parts Catalog
Porsche Classic maintains an online database that integrates PET data for older models. You can access it through the Porsche Classic website (classic.porsche.com). Select “1969” and “912” to browse categories. This is the most reliable official source, though it may not include every aftermarket or NOS part.
Downloadable PET Files
For offline use, you can sometimes find ISO images of the original PET CD. These can be run on a virtual machine or older Windows system. The 1969 912 section is included in the discs covering 1965–1970 models. Be cautious with sources; ensure the file is virus-free.
Navigating the PET for Your 1969 912
Once you have the PET open, the interface is straightforward. Here’s how to find parts for your specific car.
Selecting the Model and Year
Most PET versions start with a model selection screen. Choose “912” and then “1969.” Some versions group models by chassis number—your 1969 912 will likely fall under the “912 LWB” (long wheelbase) category, as 1969 was the first year for the longer wheelbase in the 912/911 series.
Browsing by Main Groups
The PET organizes parts into numbered groups (Hauptgruppen). For a 1969 912, the most relevant groups are:
- 1 – Engine: Includes all engine components, but note the 912 used a 1.6L flat-four, not the 911’s six. Part numbers are unique.
- 2 – Transmission: The 902/01 four-speed manual is standard; the PET shows synchros, bearings, and shift linkage.
- 3 – Front Axle: Steering, suspension, and brake components. The 1969 912 had aluminum brake calipers shared with the 911.
- 4 – Rear Axle: Rear suspension, springs, and trailing arms.
- 5 – Body: Sheet metal, bumpers, lights, and interior trim. Early 1969 models had specific rear bumperette shapes.
- 6 – Electrical: Wiring harnesses, switches, gauges. The 1969 912 used a 12V system with a generator, not an alternator.
- 7 – Interior: Seats, door panels, carpets. The 1969 model year introduced new seat designs.
- 8 – Air Conditioning: If equipped, parts are listed here.
- 9 – Accessories: Jack, tool kit, owner’s manual.
Interpreting Part Numbers and Diagrams
Each diagram has numbered callouts that correspond to a list of part numbers on the same page. For example, the engine group 1 might show a fan housing with callout 10. The list will say “901.106.201.00 – Fan Housing” along with quantity, description, and sometimes a “Notes” field for supersession.
Pay attention to the “Model” column in some versions—it may list “912/69” or “911/69” to indicate shared parts. The PET also uses color codes: black numbers are current, red are discontinued, and blue are new additions.
Common Parts of the 1969 912 in the PET
Let’s focus on a few critical systems that often need attention.
Engine and Cooling System
The 912 engine is a type 616/36. The PET shows the fan, shroud, and oil cooler arrangement. Oil coolers are prone to leaks; the part number for the 1969 specific cooler is 901.107.021.00. The carburetors (Solex 40 PII-4) are listed under group 1, and rebuild kits are referenced by individual gaskets.
Body and Trim
1969 912s had a long wheelbase, so rear quarter panels and doors are different from 1968 models. The PET includes separate diagram sets for “1969 LWB.” The front hood latch mechanism (part 901.511.105.00) is a common failure point.
Electrical System
The generator (part 901.603.101.00) and voltage regulator (911.603.211.00) are shared with 911s but listed separately in the 912 section. The fuse box diagram in group 6 shows amp ratings for each circuit.
Using the PET to Source Parts
Once you have part numbers from the PET, the next step is finding the actual components. Here’s how to proceed without relying on generic marketplaces.
Porsche Classic Centers
Porsche Classic has centers worldwide that stock a vast range of parts for vintage models. You can contact them with your PET part number to check availability. They also offer remanufactured parts for items like headlight housings and suspension bushings.
Specialty Suppliers
Companies like Pelican Parts, Stoddard, and EBS Racing specialize in early Porsche parts. Their websites often have lookup tools tied to PET numbers. For example, search “901.106.201.00” on Pelican Parts and you’ll find the correct fan housing for your 1969 912.
Junkyards and Parts Interchanges
Because many 1969 912 parts are shared with 911s of the same era, you can use the PET to identify interchangeable components. The front brake calipers (part 901.351.022.00) are the same as on the 1969 911T. Junkyards and private sellers can be searched using these numbers.
Restoring with the PET: A Practical Example
Let’s say you’re replacing the rear main seal on your 1969 912 engine. In the PET, go to group 1, engine, and find the “Crankshaft and Bearings” diagram. The seal is callout 21, part number 901.111.225.00. The diagram also shows the oil slinger and flywheel. With that number, you can order the seal from a Porsche dealer or specialist. The PET also indicates the seal is shared with the 911 2.0L engine, so availability is good.
Final Recommendation
For any serious restoration or maintenance of a 1969 Porsche 912, downloading or accessing the PET is essential. It eliminates guesswork when ordering parts and ensures you get the correct components the first time. Pair the PET with a workshop manual (like the factory 912 handbook) for torque specs and procedures. Start your project by browsing groups 1, 5, and 6 to understand the common wear items specific to the 1969 model year.
If you’re new to the PET, spend an hour exploring the diagrams. You’ll quickly become familiar with the layout, and soon it will become your go-to resource for every bolt and bracket on your classic 912.
