Porsche part number 911-628-013-02 is a specific component used in several classic Porsche models. Understanding its exact function, application, and how to correctly view it in a parts catalog is essential for owners, restorers, and mechanics. This guide provides a thorough breakdown of the part, its variations, and practical advice for locating and verifying it.
What Is Porsche Part 911-628-013-02?
Part number 911-628-013-02 corresponds to a rubber boot cover for the shift rod on Porsche 911 models from the 1970s and early 1980s. More precisely, it is the inner shift rod seal or shift rod boot that sits inside the transmission tunnel. This rubber component prevents dirt, moisture, and debris from entering the shift mechanism while allowing the shift rod to move freely.
This part is commonly associated with the 911 G-Series (1974–1989) and some late F-Series models. It is part of the shifter assembly and works alongside other bushings and seals in the shift linkage system. Over time, the rubber can harden, crack, or tear, leading to a sloppy shifter feel or increased noise and vibration.
Key Characteristics
- Material: Durable rubber compound
- Position: Transmission tunnel, around the shift rod
- Part number: 911-628-013-02 (supersedes earlier versions)
- OEM replacement: Directly replaces original part
How to View the Part in a Diagram
When dealing with a specific Porsche part, viewing it in an official parts diagram or exploded view helps confirm its location and relationship to adjacent components. The parts catalog for Porsche 911 models typically organizes the transmission and shifter system under a section called "Shifter Control" or "Shift Linkage."
Steps to View the Part
- Obtain a factory parts portal or printed catalog that covers your model year. Porsche’s own PET (Parts and Technical Information) system is the most reliable source.
- Navigate to the transmission group – look for “Shift Linkage” or “Shifter Assembly.”
- Locate the inner shift rod section. Part 911-628-013-02 is usually listed as a seal or boot that fits over the shift rod where it exits the transmission tunnel.
- Identify its orientation: The boot is installed with the larger side facing the engine side, and the smaller end facing the shifter.
Compatible Porsche Models
Although this part is most commonly associated with the 911, it also fits other models that use a similar shift linkage design. Always verify fitment by cross-referencing your vehicle’s VIN or build year.
| Model | Years | Notes | |-------|-------|-------| | 911 (F-Series) | 1965–1973 | May require adapter for early shift rods | | 911 (G-Series) | 1974–1989 | Direct fit for most variations | | 912 | 1965–1969 | Compatible with standard shift linkage | | 930 Turbo | 1975–1989 | Same shift tunnel design |
Common Failure Signs and Replacement
The shift rod boot (911-628-013-02) is a wear item. Typical signs it needs replacement include:
- Greasiness or oil seepage around the shift boot area in the cabin
- Snapping or popping noises when shifting gears
- Dust or debris entering the transmission tunnel through a cracked boot
- Stiff or notchy shift feel caused by dry, hardened rubber
Replacement Tips
- Lubricate the new boot with a silicone-based grease to ease installation and prolong life.
- Check the shift rod for rust; clean it before sliding the new boot into place.
- Inspect other bushings (like the coupling bushing) at the same time to ensure a tight shift feel.
Viewing the Part for Identification
To be certain that 911-628-013-02 is the correct component for your car, compare the part visually with your old boot. Look for:
- A specific ribbed pattern on the bellows
- A metal reinforcing ring at one end (though some versions have a plastic insert)
- The part number embossed on the rubber
If you do not have the old part, measure the inner diameter of the shift rod (typically ~10mm) and the outer diameter of the tunnel opening (~30–35mm). Genuine Porsche boots often have a slightly thicker lip than aftermarket alternatives.
OEM vs. Aftermarket Options
When viewing or purchasing part 911-628-013-02, you may encounter both OEM (Original Equipment Manufacturer) and aftermarket versions. The OEM part is manufactured by Porsche or its approved supplier and carries the exact same part number. Aftermarket boots sometimes have a different number (e.g., 911-628-013-00) but fit the same application.
| Aspect | OEM Part | Aftermarket Part | |--------|----------|------------------| | Price | Higher | Lower | | Material consistency | Exact rubber compound | May vary | | Longevity | Longest | Moderate | | Availability | Limited at dealers | Widely available |
For concours restoration, OEM is preferred. For everyday driving, a high-quality aftermarket boot often suffices.
How to View the Part Without a Catalog
If you do not have access to a digital parts catalog, you can view the part through:
- Porsche dealership parts department: Request a printout of the shifter diagram for your VIN.
- Independent Porsche parts suppliers: Many provide online diagrams with the part highlighted.
- DIY forums: Pelican Parts and Rennlist have detailed guides with photos of the shift boot installation.
Practical Considerations for Buyers
Before purchasing a replacement boot, confirm that your car uses the two-bolt transmission tunnel cover (common on G-Series) or the four-bolt version (early F-Series). The boot itself is the same, but the cover differs. Also, check if your shift rod has a pressed-on coupling – if so, you may need to remove that to slide the boot on.
Final Recommendation
For owners of a 911 G-Series or later F-Series, part 911-628-013-02 is a straightforward, low-cost fix that improves shifter feel and protects the transmission. When viewing the part in a catalog, pay attention to the diagram’s orientation and the number of mounting points. Whether you choose OEM or aftermarket, ensure the boot has the correct shape (bellows with a smooth inner bore) and no tears. If you can, inspect the part in hand before installation. Replacing this boot is a one-hour job that anyone with basic mechanical skills can complete, and it will keep your shift linkage clean and smooth for years.
