Manual Transmission Clutch Kit for Subaru Outback 2.5L

Complete clutch kit for the Subaru manual transaxle behind the 2.5L and 2.0L boxer four. Six pieces: pressure plate, clutch disc, release bearing, pilot bearing, alignment tool and a grease packet. That covers everything that should be replaced while the transaxle is out, which is the whole point — the labor is in pulling the unit, not in the parts.

Fitment covers Outback 2000-2009 2.5L, Legacy 2000-2009 2.5L, Forester 1999-2013 2.5L, Impreza 1999-2011 2.5L and 2012-2016 2.0L, Impreza 2001 2.2L, Impreza 2004 2.5L turbocharged, Baja 2003-2006 2.5L, Crosstrek 2016-2017 2.0L and XV Crosstrek 2013-2015 2.0L. Reference part numbers are 15-021, 15-004 and 623346600; manufacturer part number A4477. Confirm your part number against what is in the car before ordering, since Subaru ran more than one disc spline and diameter across this span.

Pressure plate is stamped from high-hardness steel to factory spec. Use the supplied alignment tool to center the disc in the flywheel before you torque the cover down, or the input shaft will not start and you will be fighting the transaxle on a jack for an hour. Grease the input shaft splines lightly with the packet supplied and nothing more — excess grease flings onto the friction face the first time you let the clutch out and puts you right back under the car. Resurface or replace the flywheel while it is off.

The symptoms that bring a Subaru in for this are a clutch that slips under load in the upper gears, a pedal that engages right at the top of its travel, chatter on takeoff, or a release bearing that howls with the pedal down. A howling bearing alone is still a full job on this platform, because getting to it means dropping the transaxle anyway. Kit weighs 15.43 lb and ships in a 13.39 x 13.39 x 3.94 in box.
