1992 Nissan Pathfinder SE: replace master/slave clutch cylinders

\015 After almost 180,000 miles, the clutch cylinders need to be replaced. Not having done such a repair before I'm looking for a good guide. Are the Chilton or Haynes books useful? Where else can I learn where these cylinders are located and what potential gotcha's there are in removing and replacing them?Thank you,Rich\015 Posted / edited by AnonymousUser on : 21-08-2017

Removing and replacing is straight forward mechanic work.Here is a gotcha that very few manuals will tell you,but years of experience will teach you.Go ahead and install the clutch slave cylinder on the bellhousing of the trans.The clutch master cylinder needs to be "bench bled" so that as much air as possible is gone from the master cylinder before installed on the vehicle.This requires a helper.Take master cyl. to a bench and set it down while holding the assembly in your hands.Fill the reeservoir with brake fluid.I wear latex or nitrile gloves while i work to keep my hands clean.This helps in sealing off the output fluid port during this procedure.Have your assistant take a phillips head screwdriver and push the piston in,on the master cyl and hold it in the depressed position.Some fluid and air will shoot out the output port.Now take your latex glove clad finger,and press it firmly over the fluid output hole.Now release the screwdriver.Remove finger from hole,and stroke the piston in with the screwdriver and hold it at it's depressed position.Place finger over the hole.Add fluid to the reservoir.Keep repeating until only solid fluid exits the output hole.This is bench bleeding.Now install into vehicle being careful to not get brake fluid on the paint.After installing,on the clutch master cylinder rod...there is a jam nut,either 12 mm or 14 mm.Loosen this nut and back it off.Now,the threaded rod can be spun in,or out,making the rod shorter or longer.this is how you adjust the clutch pedal engagement point,after installation.Back to the clutch master and slave,they obviously need to be bled after installation,with the bleeder valve down on the slave cylinder.Good luck.
