Dynamopoelie - Poly-V voor de 300 Tdi 2,5-liter turbodiesel, de meervoudige poelie die de dynamo aandrijft via de hulpriem.

Gemonteerd op de dynamische as, draagt de poelie de rotatie van de geribbelde hulpriem over om de dynamische rotor te laten draaien en lading te genereren. Het poly-V (meervoudig geribbelde) profiel komt overeen met de geribbelde riem voor een positieve, slipvrije aandrijving.

Frequently asked questions

What is the STC3691 alternator pulley used for?
The STC3691 alternator pulley is the multi-groove poly-V pulley that drives the alternator on the 300Tdi engine. It mounts on the alternator shaft and takes drive from the ribbed auxiliary belt, spinning the rotor to generate charge. The poly-V profile matches the ribbed belt for positive, slip-free drive.
Which engine and model does this pulley fit?
This alternator pulley fits the Land Rover Discovery 1 with the 2.5-litre 300Tdi diesel engine, from VIN VA onwards. The 300Tdi uses a ribbed poly-V auxiliary belt, so confirm your engine is the 300Tdi and not the earlier 200Tdi before ordering. Use your VIN to verify the build.
Where does the alternator pulley sit in the drive system?
The alternator pulley sits on the nose of the alternator shaft and is turned by the ribbed auxiliary belt running off the crankshaft. On the 300Tdi it forms part of the poly-V auxiliary drive that typically also turns the water pump and other ancillaries, so belt condition affects charging.
