FAQ
Everything you need to know
Which product groups does Vahdet Tiryakioğlu Otomotiv supply?
Timing kits, timing belts, poly-V and V-belts, tensioner and idler bearings, wheel hubs, wheel bearings, water pumps and fan clutches – power transmission and bearing parts for passenger cars and light commercial vehicles.
Which brands do you offer?
DAYCO, GMB, ALT, VOE and ALLES. DAYCO for timing and poly-V belts, GMB for water pumps and bearings, ALT for tensioner bearings, VOE for bearings, wheel hubs and belts, and ALLES for complete timing kits.
What is a wheel hub (porya) and what does a tensioner bearing do?
The wheel hub carries the wheel and its bearing, keeping the vehicle rolling safely and quietly. The tensioner bearing keeps the timing or poly-V belt at the correct tension on the engine; a worn tensioner can cause belt slip and serious engine damage on timing drives, so it is usually replaced together with the belt.
