A quality flat belt pulley measuring 10" diameter by 5" wide (approx), with the centre machined to suit a 1.5" shaft diameter as found on many Lister and petter stationary engines.

The pulleys come complete with a either a parallel key or a key locking bolt incorporated into the centre boss which is off centre to allow room for your starting handle to still fit onto the crankshaft. Very nicely made original looking, heavy duty pulley.
