CB Performance Serpentine Belt and Pulley Kit, 7", Black OEM Style Pulley provides almost no belt drag like V-belt systems.  This spins the fan quicker (no slipping!),  and is easily adjustable.  This kit uses a FULL SIZE pulley for maximum cooling!This kit stops the problems of broken alt/gen pulleys and thrown belts while keeping the "stock" look.  This kit is manufactured from a solid billet of T-6 Aluminum, anodized black, with the original style of the stamped steel OEM top and bottom pulleys.  It includes timing marks at BDC (for easier valve adjusting), 0 (TDC), and 5, 10, 20, and 30 degrees BTDC. 

CNC precision machined to spin true for that stealth high performance engine.  Measures 7" in diameter. 

The flat multi-grooved belt and idler pulley help reduce drag and lost power while increasing cooling efficiency and reliability.  The all NEW Billet O.E. Serpentine Belt System is easy to install.  The belt tensioner bracket is held in position by the alt./gen.  stand base bolts, just bolt it on.  Serpentine Belts run silent, true, and outlast V belts many times over. 

Fits all upright, air-cooled, VW Engines, but does NOT fit the FI engines, nor the Mexican Alternator stands! 

SCAT's kit comes with the Crank and Alternator/Generator Pulleys, Idler Bracket, High Quality Idler Bearing and Idler Adjuster, and all hardware.  When you choose your color, it will affect the crank pulley and alternator/generator pulley. 

Serpentive belts do not slip nor flip, they are more efficient than V-belts.  However, because they do not slip we do NOT recommend that you use a Serpentine belt if your engine's RPMs exceed 6000, it over-speeds the fan, since it doesn't slip like a V-belt does.  This exposes the fan to more RPMs and they often blow-up.  So a Serpentine belt system is GREAT for Cruisers (especially busses) that tend to run hot, you get maximum cooling airflow with a Serpentine Belt System. 

Stock Size Pulley, 5 Hole Sand Seal (Includes Sand Seal), 1.770" Pulley and 2.260" Case, BLACK, Laser Etched, 33-1065 is stock sized to maintain cooling air volume and charging, and dress up an engine's looks!

CB Performance Billet Aluminum Alternator and Generator Pulley, Chrome, CB 1912 is made from 6061 T6 aluminum, and includes 8 Shims for belt adjustment.  This is a really nice pulley, and dresses up your engine nicely!  These run very straight and true for vibration free performance, and a long belt life. 

This billet-aluminum pulley is an OVERSIZED crankshaft pulley that will turn the fan faster, for maximum cooling.  Good for busses and convertible beetles, in the heat of summertime!  Pulley INCLUDES the belt!  Pulley can NOT be used on full flow engines (the pulley hits the return fitting) or engines with filter-pumps. 

This pulley uses a 9.5 x 940mm belt. 

WARNING: We do NOT recommend the use of this pulley on anything more then "mild" performance use, because performance engines can over-accelerate the fan, which can result in fan failure ($$$).  Also do not exceed 5500 RPM with this pulley on the engine or the fan will over speed.  Lastly; This is a nice pulley, but the degree #s are on 180 degrees out!  It's indexed perfect, but TDC is for #2 and #4 because of this, don't let that throw you off (that's why we are telling you). 

This OEM VW Alternator Fan-Pulley is factory equipment on VW Upright engines using Bosch AL82 Alternators, now you can use it too!  The fan blades help pull additional cooling air through the alternator to keep it cool for a longer alternator life, especially if you have a high output 70 or 90A alternator.  These are NOT used with generators, ONLY ALTERNATORS! 

To PROPERLY adjust the belt, you absolutely must start with the belt too loose, and remove 1-2 shims at a time until the correct tension is achieved.  If you remove too many, you'll wind up tightening the nut until the belt is "tight enough", but the 2 pulley halfs are not squeezed together, and as the engine rotates the pulleys wear one another out.  Every rotation the outer pulley moves out at the top, then in at the bottom, out at the top, until they are ruined.  By doing it the 1-2 shim way, when you get the right tension the pulley halfs are tight against the shims and one another, and this movement and wear do not occur. 

SCAT Sand Sealed Santana Pulleys, 6 3/4", Screened Numbers, 80228 maintain cooling and charging, and have the benefit of the finest sand seal available!  A pressed on Steel Collar on the pulley snout prevents the snout from being grooved by the sand seal!  We feel these pulleys are the best pulley value in a high-quality pulley available.

SCAT 5 3/4" Sand Sealed Power Pulley and Seal Kit, Billet and Santana Style, No Machining Required, 80091 and 80092 seals your engine from pesky oil leaks around the pulley, while preventing dirt and sand from being sucked and flung into the crankcase on deceleration.  Sand seal and Collar are included, but the fan belt must be purchased separately!  Sand seal pulleys keep sand and dirt out of the engine, the "normal" pulleys are actually open, with no seal there!  Choose from 5 round holes, which is known as the "Santana Style" of pulley, or "Billet" (no holes) style.  SCAT Sand Seal Pulleys have a steel snout on the OD of the hub, which prevents the seal lip from wearing a groove into the soft aluminum hub, which is a problem with other pulley brands!

Gene Berg Sand Seal Case Cutter Tool RENTAL, GBE707 is designed to cut the engine case for a sand seal while the engine is still assembled!  This cuts the case for the VW Industry Standard of 2.250".  You must remove the crankshaft pulley and the pulley woodruff key, then you slip the tool onto the end of the crank.  Comes with a large spanner wrench to turn the cutter without skinning your knuckles and drawing blood!  It is 100% YOUR RESPONSIBILITY to check the location of the cutter bit to ensure it's cutting the case at the proper size.  We recommend starting the cut, then MEASURE, and adjust the cutter if needed, before you cut too deeply.  We do NOT have the seals, we are just offering the tool to our customers so they can use this instead of spending ~$150 for the tool that they may only use one time.

SCAT 5 3/4" Threaded Power Pulley, Billet and Santana Style, 80005 and 80006 have threads cut into the pulley snout, just like the stock pulley.  This "slings" the oil back into the case to prevent oil leaks.  These are NOT Sand Seal style pulleys.  You get to choose from the 5 round holes, which is known as the "Santana Style" of pulley, or the "Billet" (no holes) style.  Power Pulleys slow down the cooling fan, which increases available power but makes the engine run hotter!  These are NOT recommended for street cars, mostly "Play Toys". 

This is a very popular part for dune buggy and trike owners.  Custom chrome plated cover to prevent hair, clothing, and fingers from contacting the moving belt or pulleys.  Louvers in face too.  Crappy chrome finish that requires waxing to prevent rust.
