Product Information
Product Information
CAM BOLT TOOL for 911 3.2 CARRERA / 964

stomski

STOMSKI RACING's version of the P9191 tool combines the basics of the factory tool and improves on it by adding an integral 19mm bushed socket that prevents slippage and rounding off of the cam bolt on the end of the 3.2 cam shafts.
The cam bolt on the 3.2 Carrera requires a torque of 88 foot pounds. Tightening the bolt to this spec, or loosening it using a breaker bar and the factory long-armed cam tool, requires dexterity, leverage, and serious luck that the deep socket does not slip off the head of the bolt, rounding it over, or busting knuckles in the process.
STOMSKI RACING's SR9191 securely holds an impact-quality socket in the center of a precision machined hardened steel socket, ensuring ease and accuracy in loosening the bolt, or setting the required torque. The bushing prevents the socket from being leveraged off the bolt head, keeping it squarely in place for the most accurate torque and security during installation and removal.

The SR9191 replaces both the factory P9191 tool and our SR078.

Cam drive gear/inner sprocket puller for Porsche 911

stomski

More than occasionally the inner sprocket on the end of the 911 camshaft is jammed or fused in place and refuses to budge. The confined space of the chain box makes it impossible to leverage the gear off, and even if you can get an edge, chances are you will only cock the gear, jamming it further, or possibly breaking a tooth on the gear (or even mar the cam itself).

STOMSKI RACING's SR079 centers over the end of the camshaft and slips behind the sprocket flange, allowing you to smoothly and effortlessly slide the gear off– protecting both the camshaft and the gear itself (and the curse jar!). Black oxide hardened steel with stainless steel drive bolt.

Designed to pull the seized inner sprockets from the ends of the camshafts on and early air cooled 911 likes SC's etc, probably up to mid-993 as we think by then they stopped using the pin you slide in from outer sprocket into available slot in the inner sprocket which the tool is for, it's held in place with woodruff key to end of camshaft.

Crankcase head stud driver for Porsche All 911 964 993 996 / 997 GT3 & Turbo Models 1965-On

stomski

Double-nutting a head stud to install it into the engine case not only takes time, but can be stressful for the threads, and can lead to variations in stud depth (unless you are extra careful when removing the double nuts). Protect your hardware investment and speed installation by using STOMSKI RACING's Head Stud Driver.

Made from black oxide finished hardened steel, this uniquely designed tool threads onto the head stud but will not clamp on to the threads, making installation faster, gentler, and more accurate.

About Specialist Tools

Specialist Tools for Accurate, Efficient & High-Quality Porsche Engine Rebuilds

Engine rebuilds require precise measurements, correct assembly procedures and the right equipment to ensure every component fits and functions exactly as intended. Specialist tools are essential when working on Porsche engines due to their unique engineering, tight tolerances and model-specific service procedures. These tools enable technicians and enthusiasts to dismantle, inspect, rebuild and calibrate engines with professional accuracy—reducing the risk of damage, misalignment or incorrect installation.

Whether performing a full engine restoration, carrying out timing work, inspecting internal components or installing performance parts, using the correct specialist tools guarantees a reliable, long-lasting and high-quality rebuild.

What Specialist Engine Rebuild Tools Do

High-quality specialist tools ensure precision and safety throughout the rebuild process. They are designed to:

  • Accurately measure critical tolerances, including bore, deck height, ring gap and valve clearances
  • Correctly install and remove components such as crankshafts, pistons, liners and bearings
  • Support timing procedures, including camshaft alignment and intermediate shaft setup
  • Prevent damage to delicate components during disassembly and assembly
  • Improve rebuild efficiency with purpose-built fixtures and holding tools
  • Ensure even torque application, promoting proper sealing and component longevity
  • Assist in diagnostic tasks such as leak-down testing or compression verification

Specialist tools are essential for achieving a professional-grade engine build with reliable and repeatable results.

Why Workshop Tools Wear or Fail

Even well-engineered tools degrade over time due to heavy use, improper handling or exposure to harsh environments. Common causes of failure include:

  • Metal fatigue from repeated loading
  • Worn or stripped threads on pullers, press tools or torque tools
  • Corrosion from moisture or chemical exposure
  • Heat damage from working near exhaust or cylinder heads
  • Loss of calibration, particularly with measuring or torque-sensitive tools
  • Damaged contact points from misuse or excessive force
  • Contamination from debris or workshop dirt

A failing tool can cause inaccurate measurements, unsafe working conditions or even costly engine damage.

Why Specialist Tools Should Be Replaced or Upgraded

Replacing worn tools or upgrading to precision-engineered alternatives provides clear benefits:

  • Improved measurement accuracy for critical engine dimensions
  • More reliable component installation, reducing the risk of misalignment
  • Safer workshop practices, preventing injury or engine damage
  • Consistent torque and calibration, essential for sealing and bearing load
  • Enhanced efficiency, saving time during complex rebuild procedures
  • Better compatibility with modern engines and performance upgrades
  • Higher quality rebuild outcomes, improving engine reliability and longevity

Using proper tools is an investment in the quality of the rebuild and the health of the engine.
