021-119-249E VW Bus Plastic Timing Scale - 1972-1979 Type 4

Plastic Timing Scale – 021-119-249E

The 021-119-249E is a precision Plastic Timing Scale designed specifically for the Volkswagen Type 4 engine. Mounted to the fan shroud or engine case near the crankshaft pulley, this scale provides the numerical reference points needed to set your ignition timing accurately. On the late-model Bus motors, having a clear and intact scale is the only way to verify Top Dead Center (TDC) and set the proper degrees of advance or retard.

Because this part is made of plastic and lives in a high-heat environment, original scales frequently become brittle, crack, or melt over decades of service. If the markings become unreadable or the scale falls off entirely, tuning the engine becomes guesswork. Replacing it with a fresh 021-119-249E ensures you can maintain your engine’s performance, fuel economy, and cooling efficiency by keeping the timing exactly within factory specifications.

Product Highlights & Features

• Essential Tuning Tool: Features clearly molded degree markings to allow for precise ignition timing adjustments using a timing light.

• Heat-Resistant Polymer: Manufactured from a durable plastic compound designed to withstand the ambient heat of the engine compartment without warping.

• OEM Fitment: A direct replacement for the original Volkswagen part, ensuring the mounting holes align perfectly with the factory locations.

• High Visibility: Provides a clean, high-contrast surface for the timing marks, making them much easier to see in the tight confines of a Bus engine bay.

Technical Specifications

• Application: Engine Timing Reference Scale

• Engine Type: Type 4 (1.7L - 2.0L)

Installation & Maintenance Tips

• Clean the Pulley: For the most accurate results, clean the notch on your crankshaft pulley and highlight it with a dab of white paint or "liquid paper." This makes the mark "pop" when hit by the strobe of your timing light against the scale.

• Gentle Tightening: When screwing the scale into place, do not over-tighten the mounting hardware. The plastic can crack if too much pressure is applied, especially if the mounting surface isn't perfectly flat.

• Check for Rubbing: After installation, rotate the engine by hand to ensure the crankshaft pulley or any belts do not come into contact with the scale.

• Stay Clear of Degreasers: When cleaning your engine, try to avoid spraying harsh solvent-based degreasers directly onto the plastic scale, as these can eventually cause the plastic to become cloudy or brittle.
