Crankshaft Pulley, Part Number: 996 102 115 63, also referenced as 996-102-115-63. Fits Porsche models equipped with M96 and M97 engines, including Boxster, Cayman, and 911 variants from approximately 1997 to 2008. It transmits rotational force to drive accessories via the belts (e.g., alternator, power steering, A/C) and helps absorb crankshaft vibrations, protecting engine components and maintaining smooth operation.

Fit:
Porsche 986 Boxster 1997-04
Porsche 987 Boxster 2005-08
Porsche 987C Cayman 2005-08
Porsche 996 C2/C4/C4S 1998-04
Porsche 997 3.6L 2005-08

Crankshaft pulleys like this one are designed to last the engine's lifetime, but here are the common failure modes to watch for: 

• Rubber deterioration or separation causing excessive vibrations 
• When the vibration damper fails, crankshaft vibrations aren’t absorbed, leading to noticeable engine shake—especially at certain RPMs—which can damage internal components and accessories. 
• Noisy operation or belt misalignment. A failing pulley may cause the belt to slap or misalign, resulting in rubbing noises or excessive wear. 
• Battery warning light or charging glitch. If the pulley fails and stops turning the alternator belt, the battery light may illuminate due to loss of charging.

Exhaust bolt repair kit for Porsche DFI Engines on 911/997/991/ Boxster & Cayman (9A1) 2009-Onwards



Holy broken bolts Batman! Even the latest generation of DFI (9A1) heads on the water-cooled engines are reporting broken exhaust bolts. Tasks ranging from a simple exhaust system update through an engine removal, are consistently plagued by snapped, rusted, and broken exhaust manifold bolts. Rarely can an accurate removal of the broken bolt be performed with the engine in the car, and even after removal, the task is time consuming and if not done carefully can lead to a damaged head or faulty repair. STOMSKI RACING's answer to these problems is the SR069, a kit that easily, accurately, and flexibly allows you to drill out the broken bolts - with the engine still in the car- saving time and headaches. A CNC milled plate indexes precisely off the broken bolts and/or bolt holes. Using our uniquely designed Thumb Screws, the SR069 plate is locked in place (by threading a Thumb Screw over a broken bolt or by using a supplied bolt threaded through the SR069 Thumb Screw). With the included pilot drills and drill guides, the faulty bolt can be drilled out, producing a perfectly perpendicular and centered hole that if necessary can be chased with an included M8x1.25 tap.

Kit includes anodized aluminum fixture, drill bits, tap with extension, drill jigs/guides, Thumb Screws, and hardware in a sturdy storage case. Also includes our SR065D drill guide.
