A Quick Look at Porsche

Porsche information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.

Choosing the Right Fit for Your Porsche

Where Porsche is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.

  • Typical reasons people replace these parts include maintaining originality, keeping factory specification, and choosing the latest genuine revisions for peace of mind.
  • Common real-world issues behind many Porsche repairs are age and mileage: oil leaks, cooling system fatigue, brake and suspension wear, corrosion and electrical faults from moisture or heat cycling.
  • Before ordering, confirm part numbers against VIN or option/PR codes, especially for safety‑critical or complex components.
  • When upgrading, decide whether you want pure originality or performance changes, as some aftermarket options may suit specific goals better than genuine.
  • For bigger jobs, replace related seals, hardware and consumables at the same time to avoid repeat labour and compatibility issues.
  • Where available, follow the manufacturer’s fitting and bedding‑in guidance to get the best performance and longevity.

Browse by Category

If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.

Brakes — Brake components are renewed to restore stopping performance, address wear or upgrade a Porsche for fast road or track use. Common symptoms include: Common symptoms include vibration under braking, increased stopping distances, squealing, pulling to one side, warning lights and visible wear to discs and pads.

  • Check whether the parts are OE-equivalent replacements or performance upgrades and match this to how the Porsche is used.
  • Follow any recommended bedding-in procedure and consider replacing discs, pads, sensors and fitting hardware together where advised.

Clothing & Gifts — Porsche-themed clothing and gifts let owners and enthusiasts show their passion off the road, or make ideal presents for fans of the marque. Common symptoms include: Items may become worn, faded, damaged or go out of style, prompting replacement with newer designs.

  • Review available size, colour and material details to help choose the right item and ensure it matches how it will be used.
  • Check any care or washing guidance so garments and accessories keep their appearance for longer.

Lifestyle — To explore different Porsche-inspired lifestyle products or gift ideas. Common symptoms include: General wear from handling or display.

  • Confirm whether items are official Porsche lifestyle products or from trusted partner brands where stated.
  • Consider who the item is for and how it will be used day to day to select the most suitable style or product type.

Keyring — To choose a different design, material or model theme. Common symptoms include: Scratches, worn finishes or loose fittings.

  • Keyrings make simple, practical Porsche-themed gifts and can be matched to specific models or heritage designs where available.
  • If a keyring shows damage or looseness, replace it to avoid losing keys or further wear to finishes.

Size chart — The size chart acts as a practical reference tool for all apparel purchases. Common symptoms include:

Product Information

Shim washer for alternator belt pulley 0.5mm for Porsche 911 models, used to fine-tune alternator belt alignment and tension across classic 911 applications from 1965–1989.

What This Product Does
This 0.5mm shim washer sits between the alternator belt pulley halves to adjust pulley spacing, helping to achieve correct belt tension and alignment. Using the appropriate number of shims supports smooth belt operation and reduces the risk of premature belt wear.

Functions

  • Spaces the alternator pulley halves to achieve correct belt tension
  • Helps align the alternator belt with adjacent pulleys
  • Allows fine tolerance adjustment in 0.5mm steps
  • Contributes to stable alternator and cooling fan drive

Symptoms of Fault

  • Squealing or chirping from the alternator belt area on start-up or under load
  • Visible belt slack or difficulty setting correct belt tension
  • Uneven belt wear or fraying at the pulley edges
  • Traces of belt dust around the alternator and pulley
  • Intermittent charging issues linked to belt slip
  • Overheating risk on engines where the belt also drives the cooling fan

Why Replacement Matters
Alternator and fan belt systems on classic Porsche 911 models rely on a stack of correctly sized shims to set belt tension within specified tolerances. Missing, damaged, or incorrect shims can make precise adjustment difficult, leading to belt slip, noise, and accelerated wear. Replacing worn or lost shim washers when servicing the belt or pulleys helps restore proper alignment and tension control, supporting reliable charging and cooling operation on older 911 engines.

Fits

  • Porsche 911 & 912 (1965–1989)
  • Porsche 911 1974–1977 2.7L / 1976–1977 3.0 Carrera
  • Porsche 911 1975–1977 3.0L Turbo (930)
  • Porsche 911 1978–1983 3.0L SC
  • Porsche 911 1984–1986 3.2L
  • Porsche 911 1987–1989 3.2L G50

FAQs

  • Q: How many shims should be used?
    A: Follow the Porsche workshop manual for your specific model. The total number of shims is usually fixed, with the split between in-use and parked shims determining belt tension.
  • Q: Where are the spare shims stored?
    A: Typically, unused shims are kept under the pulley nut or outer pulley half so they remain available for future adjustment.
  • Q: When should shims be renewed?
    A: Replace shims that are bent, corroded, damaged, or missing when changing the alternator belt or pulley components, to ensure accurate tolerance adjustment.

Support & Advice
Ensure you use the correct combination of shims to bring the belt tension within the recommended tolerances for your engine. Always confirm fitment against your vehicle details (model, year, engine) before installation.
