Detailed Description

This Gates DriveAlign Premium OE Pulley 38771 is a steel accessory drive belt idler pulley with a 75 mm outside diameter, 26 mm width, and 17 mm bearing bore inside diameter. The smooth backside contact surface is suited to belt paths that ride on the back of the belt rather than in a grooved channel, helping maintain proper accessory drive routing in the water pump position. This part cross-references Genuine 11287598833 for the same application.

Compatible With 2009-2016 Mini Cooper, water pump; 2011-2017 Mini Cooper Countryman, water pump; and 2013-2016 Mini Cooper Paceman, water pump. If you are replacing a worn Mini Cooper water pump idler pulley or servicing the accessory drive belt system on a Mini Cooper Countryman or Mini Cooper Paceman, Gates 38771 provides an OE-style replacement option.

What It Helps Address

Installation Notes and Tips

Verify pulley dimensions, belt routing, and the water pump position before installation. Inspect the accessory drive belt, tensioner, and adjacent pulleys for wear at the same time, since related components can affect belt noise and alignment. Confirm the OE comparison rating and part number 38771 against the original pulley before ordering.
