Ford F-650 Clutch Master and Slave Cylinder CC649051

This is a pre-filled, pre-bled clutch hydraulic assembly for Ford F-650 and F-750 medium-duty trucks with a manual transmission. It includes the clutch master cylinder, the hydraulic line and the slave cylinder with its pushrod, joined and filled at the factory. It replaces CC649051, 4C4Z-7C535-AA, AB, AC and AD, 2C4Z-7C522-A, AA, AB and C, 2C4Z-7C535-AA, YC3Z-7A543-AA, YC3Z-7C522-AB and D701050.

Listed fitment is the 2002-2008 F-650 and F-750, the 2009 and 2015 base trucks, and 2013 XL and XLT trucks, with the Caterpillar or Cummins diesel. Medium-duty trucks built these years can have different clutch setups, so check the part number on your old assembly or compare it side by side before you order.

Because the system comes sealed and full of fluid, you install it as one piece: mount the master at the pedal, route the line along the original path, and bolt the slave to its bracket with the pushrod on the release fork. Do not pull the line apart to route it, or you will have to bleed it. Once it is in, top off the reservoir and check the pedal feel.

Replace the whole assembly when the pedal sinks or goes soft, the reservoir keeps dropping, fluid is wet at the firewall or around the bellhousing, or the truck grinds into gear because the clutch will not release. On a truck this old the master and slave have worn together, so doing both at once saves a second repair.
