The WEVO XE-010 Crank Pulley is designed for back date 3.6 liter installations and other 3.6 liter motor upgrades where the dual O.E. Dual crank pulley is eliminated. It is intended for 993 3.6L motors only - with the parallel mount on the crank (not the taper mount as found on the 964 motors).
Unlike the many small diameter aftermarket pulleys available for the 3.6 motors, the WEVO XE-010 offers the O.E. diameter on a single pulley design and therefore maintains O.E. fan speed and a higher (than small aftermarket pulley's) alternator speed. In some applications this can be imperative to maintain adequate engine cooling and electrical system voltage in stop-start traffic conditions.
The WEVO XE-010 has been specifically designed to fit within the 3.2 Carrera Engine mount console XXX>XXX>XXX>XX. This allows easy mounting of the 3.6 into the 1965 - 1989 chassis using the early engine mount cross beam XXX>XXX>XXX>XX with the 3.2 Engine mount console and stock 911 engine mounts.
Manufactured from heat treated alloy steel, carefully lightened and finished with black zinc plating, the WEVO XE_010 Crank Pulley also has engraving for "Z" and the other marks on the 964 and 993 O.E. Pulley's.
This Pulley is ready to install as supplied and uses the O.E. pulley bolt you already have.
In conjunction with the single pulley kits for the 964 and 993 Alternator - available from several other vendors - the XE-010 uses the XXXmm V-Belt part # XXX>XXX>XXX>XX.
