How- To: Clutch Slave Cylinder bleeding
By OB



This is a very easy and fast procedure. It can be done without raising the front of the vehicle, but it is much easier when done from below. My steps and pictures are based on doing this procedure from underneath the transaxle. Expect to spend 10-30 mins on this procedure.


Note: This procedure is for all T-350 equipped manual tranaxle vehicles ONLY.

_____________________________________________________

Tools and Equipment:

Ratchet & short extension (3-4")
10mm socket
Brake fluid (DOT 3 or 4, whichever you use).

_____________________________________________________


STEP 1: Pump the clutch pedal 30-50 times, check for a spongy feel. If it feels good, your clutch fluid circuit probably does not need bleeding. Top off the fluid level in your clutch fluid reservoir if needed. If the pedal feels spongy or you're suspicious that air might have made its way into the system, proceed to STEP 2 below.

STEP 2: Raise the front of the vehicle enough for you to get under it and have some space to work. Be sure to secure it on jackstands for safety.


STEP 3: Locate the clutch slave cylinder. It is attached to the transaxle bellhousing via two 10mm screws (see pic below). Remove these and pull the cylinder away from the transaxle while sliding the flange (where the screws go through) towards the ground. The pushrod should come free from its seat and the whole cylinder will be free from the tranaxle. Be sure not to disconnect the fluid line going to the cylinder.

Note: DO NOT pump the clutch pedal after the slave cylinder has been disconnected from the transaxle. This could cause damage to the pushrod and cylinder internals.

STEP 4: Allow the slave cylinder to hang at the lowest possible position without putting stress on the fluid line (see pic below). Proceed to pump the pushrod all the way into the cylinder bore and back out 10 times. Be careful not to break the T-shaped tab at the end of the pushrod. Once the bleeding is complete, reinstall the pushrod into its seat and snap the slave cylinder body back into place. Be careful not to bend or damage the fluid line or pushrod during reinstallation. Reinstall and tighten down the fasteners.

Pic 2: Slave cylinder; pushrod.

STEP 5: Top off the fluid reservoir if needed. Proceed to re-pump the clutch pedal 30-50 more times, or until you feel that it is operating correctly. If it still feels spongy, you may have an internal issue with the master cylinder or the slave cylinder itself. The OEM recommends replacement of BOTH units to correct this issue. I would suggest trying to re-bleed the slave cylinder circuit once more before condemning any components.

That's it, you're done. Lower the vehicle and take it out for a test drive. All questions and comments are welcome, thanks for looking.

THANK you for posting this !! :thumbup:

There's been a need for this, I've seen people posting asking how to do this.... As far as I know, this is the first writeup I've seen on bleeding the slave cylinder.

I did this and the plastic thing broke off while trying to bleed it... so i had to replace it and then when we tried bleeding it second time the screw stripped


but we did not follow this meathod... we just bleed it a little pumped the clutch... bleed it some more pump the clutch to it seemed like all the air was out


so i'm hoping we can repair the screw and the clutch is good

Pump, remove slave, pump slave by hand, install slave, be done.

No problem homes. Yeah according to the FSM the system will purge air on its own without being cracked open. Strange, but that's what it says.

You'll have to crack the line or siphon the fluid out through the reservoir. Once it's full of new fluid, bleed it a few times and you should be good. The FSM doesn't show anything on swapping fluid, or I would post it up.

you COULD open the slave up, remove the rod, and let the old fluid flow out that way.............but do that at your own risk.....no guarentee itll work.

Sure dude, no prob. The stock clutches have a pretty crappy feel from a performance standpoint, so it's probably just normal :)

I don't see why it would be different.
I'm sure someone will confirm.

I believe that 'esteinmaier' has already posted a how-to, on using the slave cylinder from a Mistu Eclipse.
I thought he was also offering a kit at one time.
I would try contacting him for more details.

its going to be stiff to compress, thats normal, if you cant work around that bracket just remove it, it wont hurt anything to remove it temporarily while you bleed the line

That's what I would do..... Just remove it, and re-install it when you are done.

That is a support bracket for the IM. There is also another bracket on the other end. You may want to clean it up and put a fresh coat of paint on it at least, while it is out.

On the Magnum IM, it is a different bracket, and it is not recommended to leave it off. There have been a few cases of the aluminum cracking at the flange.

I don't have either bracket on mine, but then there are no longer any mounting points on my IM. :roll:

But then 1gn plastic runners are a little more flexible than 2gn plastic runners.

Oh, well I was able to push the pin the the max in and got it out and man my arm still sore from the work. Plus I follow this youtube video from perfection clutch where it show me how to bleed it and understanding the concept easier, and no clutch pumping require much, since it's an external slave that our neon uses.
