non mechanic looking for guidance with clutch repair! (bleeding)

Hi, im not a mechanic and the most i know about cards is how to perform and oil change and air filter, spark plug changes etc.

does anyone know where i can look for help on how to bleed the clutch. I have a problem where the car was in storage for some time and when i took it out the clutch fluid cylander (little plastic container with the fluid in it) was empty. So i think theres now an air bubble or something because every now and then the clutch plays up and causes gears to be stuck in gear. The main time this happens is reversing and taking off in 1st gear or doing hill starts. If you ride the clutch even slightly you get it stuck in gear and the clutch becomes all loose and only by stopping the car and pumping the clutch can u get it out of gear.

i've been advised by a couple of people and websites that i need to bleed the clutch and i have a car ramp to put the car up on but the whole problem i have is i dont know where to look to BLEED to clutch from. I know how the bleeding process works but where is the part you unplug to bleed it? a full set of guildlines with pics would be great but otherwise what should i do? i can't afford a mechanic i'm only a poor student and just spent all my money getting my RX7 back on the road and just need to get this clutch problem sorted out.

I have a 12A series 2. if that helps, and very little has been done to the car. Ok... thanks hopefully someone can help. You may email me directly if that seems like a good idea.

cheers,

Matt.

Simple. Ad fluid, loosen the air bleed nut on the slave cylinder (follow the line from the master cylinder-on tranny) use a 10mm open wrench. Then have someone step on the clutch pedal a few times or until the fluid comes out of the bleed valve. Then tighten the valve while holding the clutch pedal down, refill and that should do it. My guess is your Master or slave cyliders need replacement.

Or your master and slave could be rebuilt. Rebuilding is fairly easy, but for a non-mechanic replacement is easier.

Incorrect.


I think it is an 8 mm and use a box wrech or risk messing up the bleader.

To bleed it.

Add Fluid.
Open the bleeder, put a rag over it, have someone push down the peddle, close the bleeder.
Do it again.
Do it again.
Now have that someone press the peddle, open the bleeder so the slave cylinder moves. close the bleeder.
Do it again.
Do it again.

You should now be good to go.

You need 8mm wrench, a beer bottle (halfway filled with water- drink the beer first) and a piece of hose (one end on the bleeder and the other submerge on the beer bottle). You can actually see the bubbles or air coming out.

I use a plastic peanut butter jar. Drill a hole in the lid so the rubber hose fits snug, add a little brake fluid to it. No mess, no fuss, no spills, no peeling paint from the brake fluid. Small jar works better than the larger ones.

I wasn't able to get it bled well until I took the slave off the tranny housing and raised it up above the level of the master cylinder. YMMV.

You guys are awesome! Thanks heaps, i'll print it all out and take it with me today when i attempt to bleed the clutch to hopefully find out whether its just a bit dirty and has air in it or what.

Thanks heaps guys i'll put some pics of my RX7 up after i've fixed it all up and its looking better. no point yet until its all ready.

It can be difficult to bleed the clutch. Start by replacing the flexihose that goes from the MC to the SC. It only costs about $15. You may need to bleed several times. See if you can get a "Speed Bleeder" to replace the ordinary bleed tit on the SC: sometimes available at the autostore, but get the right thread size.

Some guys use a Power Bleeder.
