Degree Crank Pulley, Sand Sealed, Bolt In, Standard Diameter

OVERVIEW

Precision timing and engine longevity are the cornerstones of any high-performance air-cooled Volkswagen build, and the EMPI Sand Sealed Degree Crank Pulley is engineered to deliver both. Designed specifically for enthusiasts who demand more than just a stock replacement, this standard diameter pulley features a sophisticated sand-seal design that creates a physical barrier against the elements. Whether you are tearing up the dunes in a sand rail or navigating dusty backroads in a Baja Bug, the included seal and collar system prevents abrasive grit from entering your engine case through the crank snout. This significantly reduces wear on your main bearings and keeps your oil cleaner for longer periods, ensuring that your investment stays protected even in the harshest off-road environments. The five-hole design offers a classic, performance-oriented look while maintaining the structural integrity needed for high-RPM applications.

Beyond its protective capabilities, this pulley is an essential tool for any mechanic or DIY builder looking to fine-tune their engine''s performance. The pulley face is meticulously engraved with high-contrast black degree markings and numbers, allowing for pinpoint accuracy when setting ignition timing, checking total advance, or performing valve adjustments. Because it maintains the standard stock diameter, you won''t have to worry about overheating issues often associated with smaller "power" pulleys that slow down your cooling fan. This kit comes complete with the necessary seals, collars, and spacers to facilitate a professional-grade installation. Please note that because of the additional thickness provided by the sand-seal collar, this unit requires the use of an extra-long pulley bolt (EMPI P/N: 00-9118-0) to ensure proper thread engagement into the crankshaft.

PRO TIPS

1. Verify Top Dead Center (TDC) Accuracy

While EMPI degree pulleys are manufactured to high standards, you should never assume the "0" mark perfectly aligns with your specific crankshaft''s TDC without verification. During engine assembly or before final installation, use a piston stop tool to find the exact Top Dead Center of the number one cylinder. If the mark is slightly off due to crankshaft keyway variances or case machining, use a small file or paint pen to create a corrected reference point. Accurate timing is the difference between a crisp-running engine and one that suffers from pre-detonation or sluggish performance.

2. Proper Seal Lubrication and Installation

The sand seal system relies on a tight tolerance between the collar and the rubber seal. Before sliding the pulley onto the crankshaft, apply a generous amount of high-quality engine assembly lube or clean engine oil to the inner lip of the seal and the outer surface of the collar. This prevents "dry start" friction which can burn the seal lip and cause an oil leak immediately upon startup. Ensure the seal is seated perfectly square in the adapter to prevent uneven wear and ensure a vacuum-tight environment for your crankcase.

3. Don''t Forget the Extra-Long Bolt

One of the most common mistakes builders make when upgrading to a sand-sealed pulley is attempting to reuse the stock crankshaft pulley bolt. The sand-seal collar adds roughly 1/4 to 3/8 of an inch of thickness to the pulley hub. A stock bolt will not have enough thread engagement to safely hold the pulley at high RPMs, which can lead to the pulley backing off and destroying your crankshaft snout. Always pair this pulley with the EMPI 00-9118-0 Extra Long Bolt and torque it to the factory specification of 33-43 ft-lbs to ensure a secure, fail-safe fitment.
