  • On pre-2003 Boxsters and Carrera 996s, the engines all had five chains: two linking each pair of camshafts to the intermediate shaft, one linking the intermediate shaft to the crankshaft, and two linking each camshaft together. I'm not sure why Porsche designed it this way: most modern cars don't have this many chains. The good news is that on these early 5-chain cars, the timing chains almost never skip a tooth when performing the intermediate shaft bearing replacement. The chains are very tightly wrapped around each gear and as a result, when you loosen the tension from them, they tend to stay in place.

Intermediate Steering Shaft Repair/Replacement

The Pelican Parts intermediate shaft bearing replacement kit is shown in and contains everything that you need to perform the replacement in either a single- or dual-row bearing engine. The Pelican kit uses the same bearing that Porsche used when originally building the engines, but the kit incorporates a stronger seal on the outside of the bearing. The kit is designed so that the bearing replacement can be performed during a routine clutch replacement (see ). Changing out the bearing during each clutch job will ensure that the bearing is fresh and not wearing prematurely. As stated in the previous section, the failure mode of this bearing is not well known--if it's swapped out and replaced every 30,000-45,000 miles when the clutch is renewed, it should protect your engine from problems.
