Pulley kit comprises of a precision machined stainless steel hub which is permanently attached to the alternator with the standard nut. 3 different sized pulley are supplied which give different drive ratios The smallest pulley gives the standard ratio for standard fan speed the larger pulleys reduce fan speed and allow you to fine tune fan speed for your application-Top pulleys are easily swapped by removing the five M6x12 cap screws.

Small diameter bottom pulley with separate steel hub ,sand seal, pulley bolt and washers
Available with plain hub or with teeth in the 36-1 pattern and crank sensor (vr) see options

VW Speed Shop belt tensioner
This new design of tensioner has larger bearings than most other tensioners and a larger diameter roller
to reduce bearing rpm.Slide mechanism has much longer travel which allows use of one belt size to fit
all top pulleys. As with all tensioners the alternator pedestal may need attention to produce a flat mounting
position for the base,the roller must sit perpendicular to the belt travel for correct operation

Crank Trigger

Due to the small diameter of the pulley and position of the sensor make sure there is sufficient
clearance between bracket and back of pulley some tweaking maybe required set sensor gap between
0.5mm and 1mm

Hubs

3 hubs are available. Plain steel hub for use without crank trigger, steel hub with 36-1 tooth pattern uses sand sealand
the stainless hub with reverse thread like stock pulley and 24-1 tooth pattern
