1992 4x4 4.3 motor 5 speed. What tool do i need... to remove lines from clutch master cyl.

a plastic master cyl !

master cyl is bypassing internally

slave cylinder is inside the gearbox bell housing
if its leaking .....gearbox out

disconnect fluid line to slave cyl. disconnect cyl rod from pedal, unbolt cyl and remove install in reverse order, fill master and bleed at slave cyl

could be a broken engine / trans mount unfortunately a common finding nowadays
if your familiar with tools use a large wrench on a large bolt located someplace on front of SHUT off engine gently but with force attempt to move engine North/east/south/west if it moves any direction more than 1/4 inch in respect to car body (not ground) yep you got a broken one

ooh also ck clutch master cyl fluid level (not brake master cyl) for correct level if low u got a leaky slave cyl

No it won't Gary.

If your clutch is hydraulic uses a master cyl. and a slave cyl. It sounds like the slave cyl. but could be both.

look for leak....under the dash on the floor if its wet there its the master. Just follow rod from clutch peddle to master. Check the line and not sure if your slave is on the outside of the trans look there or if its in the trans see if its wet coming out of the bell housing (where trans meets engine) and replace that part and bleed system

it is the same deal as brakes it is easy to do and the same things you need to cange master cylinder for the brakes is the same for this little project tools and all the master cylinder for the clutch is smaller then brakes master cylinder and only has one line going out so its a small task

If you've not done anything to your truck, check the Clutch master cylinder under the hood, there is a resivoir that should have brake fluid in it. It usually sits next to the Brake master cylinder & is a smaller unit. If nothing has been done to the system recently, and your fluid is full, either the Clutch Master Cyl. or the Clutch Slave Cy. mounted on the bellhousing of the trans. is defective, or has a leaking connection.

If leaking connection, tighten & bleed the system. Check under the clutch pedal on the floorboard for brake fluid, if you find it, the Clutch Master Cyl is the problem & will need ot be replaced. Otherwise, the Clutch Slave Cyl. will need to be replaced. System has to be bled after replacing either & the Clutch Master Cyl. must be bled before hooking up the lines to the Clutch Slave Cyl.

Good Luck

good luck.

the master cyl is at the pedal and the slave cyl is the one at the clutch operating end this can be either internal or external of the clutch casing so if you have a problem with clutch operation ?and not sure which/or what is fault ? why not give symptoms ? so we can advise you b4 you spend ?

have some push all the way down on the clutch than squeeze the plastic tabs on bushing to release u also need a special tool to remove disconnect the hydraulic line from clutch release cylinder most auto stores carry it or let u use /loan for free
