What is the best way to replace the slave cylinder on an 1989 Ford F-150 4X4?

Answer 1

Slave cylinder/clutch 1992 F150

I just replaced the slave cylinder and clutch on a F150 1992 straight 6 (4.9L) 5spd. If it is the internal concentric slave cylinder, you will need to split the transmission from the engine. Take both driveshafts loose, the speedometer cable, mounting bolts to the transmission bracket, and both gear shifters, and support with floor jacks. The engine should be supported as well. There are 6 bolts around the bell housing to remove. Mine took a 5/8" wrench. You might need to remove the front fuel tank, depending on clearance. I would suggest making a couple of bolts that are the correct diameter to use as lineup pins when you put the whole system back together. When you have it split, there are two bolts w/ 10mm heads to remove and the whole thing comes out. A quick attach hydraulic coupler attaches the hydraulic line to the slave cylinder, you need a little plastic tools to push down on it, and it comes apart. Simply put it back together in reverse order.

If its an external slave cylinder, like my Dad's 1993 F250 7.3L turbo diesel, its. easy. Snap the slave cylinder off the bell housing, use a punch to drive the roll pin through, and its apart. There is a small rubber o-ring in there that will come with the new kit, do not forget to install it. The rest of the directions are with the new slave cylinder, and its a gravy job. If you've done it before, 15min will do it with a friend to help bleed the system. If its internal, sorry but it will take some time. If you're in there that far, at least replace the throwout bearing. I'd inspect the clutch as well. Mine was $150.00 at Advance Auto for the whole thing, pilot bearing, clutch, pressure plate, and throwout bearing. Getting the pilot bearing out of the crankshaft was the worst part. I ended up using a die grinder and a chisel.
