The presence of a gap in the grooved section of the power steering pump pulley (see Illustration), may be misdiagnosed as a crack.
The pulley is designed and manufactured with a provision for the gap to be present and has no negative effects on the accessory drive system.
A gap width of up to 1 mm should be considered normal.
A power steering pump pulley should not be replaced due to the presence of the gap.
