I’m installing a new slave cylinder myself I did as you just did but I have a little bit of fluid coming out of it is that normal
If it is a Dmax slave cylinder and it is leaking, something is wrong.
How about bleeding process of the slave if already installed?
Best video on the Hydraulic slave cylinder without a bleed valve
Thanks!
Hello, thanks for the video. I have Fiat Bravo 2 1.6 multijet 105hp. From 1-2 weeks I have an issue with the clutch - when I am going on first and reverse gear the car is vibrating and annoying rasping sound is heard on the front of the car. Sometimes I am not even able to shift the gears and when I turn off the car and pump the clutch and then the car start shifting and driving off without vibrations. Could it be a problem with the clutch release bearing? Or because of old brake fluid and air in the system? Thanks in advance!
Have a 95 Chevy Cheyenne 2500 series truck with an Ev 4500 transmission how do I bleed that clutch it's a different set up then you're showing
I got a chevy cobalt just had whole entire clutch system done from flywheel all the way up to the brake master cylinder and after i was back bleeding it like this from the bleeder screw on the outside line i got pressure back on the pedal itself but a hour later clutch pedal goes dead again..iv vacuum blead it from bmc still happens. Its not leaking fluid and its not taking air in anywhere..I didnt install the clutch just how i received the car. I was told by owner oh it just needs to be back blead theres a air bubble in there..could this be why it keeps loosing pressure? Cause it probably wasnt bleed from the slave..? Thanks
Very helpful, thank you
Glad it was helpful!
I have a question,we already replaced new clutch component ,but there is a problem,Its hard to engage the gear to 1st ,but the rest are smooth.what should I do
Does this also work for the NV1500 on S10's?
okay update and added safety tip. I have a 92 f150 with 302 and M5OD it has a very similar setup with the slave it has a bleeder but some slave you buy aren't pre bled "dry". what I've done was install everything but before stabbing the transmission you can push the slave back pushing the cylinder all the way down pushing air up to the master. it called reverse bleed. But DO NOT start pushing the pedal down you will blow the slave cylinder apart and eat some brake fluid but you can atleast get the air out of the cylinder. The throw out bearing needs pressure on it from the fingers on the clutch to prevent it blowing apart. Hopefully this clears it up for them M5OD guys searching to help bleed the slave. Another comment I seen was can you do it with the transmission installed the answer is yes a pry bar on the bearing works but be careful understand with the pry bar you're apply a completely different force on one section of that bearing if you have a fork you can get away with this method. 😉
Thanks for the added info!
@furmom9390 I have a 1990 f250 with the 5.8 5speed and I did the internal slave cylinder, and I can't get it to bleed. I tried what you said with a pray bar pushing the slave cylinder back kind of pumping it. Whole doing that I took a video of the fluid reservoir up top and nothing was happening. Any thoughts?
Opel (waxhaul) has them internal also...
Glad I'm researching this, VW is like this too on MKVI now...what a pain.
There is no real way I can think of once the transmission is put back together. I'd imagine if it is you'd probably disconnect the hard line at bleeder valve for clutch and put a hose that fits around it connected to a bottle of hydraulic fluid then .... nope, you can't. Then you can't press it down without the clutch master connected. With the clutch master connected maybe you could from there , if not you'd just keep trying to compress air bubbles.
Thanks for this, doing it connected to a long hose full of fluid to make life easier since I don't have a lift and want to deal with the short length of mine
Any luck in finding a way to bleed the clutch with the slave already sealed in the transmission?
@@DavidMartinez-kp4wp I ended up bench bleeding it as best as I could. The thing is, once it's put on the cylinder compresses and pushes out whatever was in it already soooo, if you had the line connected right away with it primed it would pull it all from master and be fine. If it was a dry pull from master hose then.... Uhhh. I read lots of bleeding and then some after you think it's fine. Sorry :(
I added a hose to my master as I pushed it back on that I filled with the brake fluid and watched it push/pull it all back in
Mine has issues of getting stuck in first gear now and having to turn it off.... I blame Spec and the spacer being off by thousandths :(
@@Hedgehodge- thanks. I have a South Bend clutch on my MK7 with similar conditions. It locks up on first and reverse from a stand still. Shutting it off disengages it or by moving the car slightly. What's weird though it doesn't happen when the car is cold. Only when the engine is warm.
@@DavidMartinez-kp4wp did you install yours too? I'm OCD and wanted to make sure it was don't right and torqued etc. I tried the spaced on the outside transmission cap for input shaft, no play at all. Didn't want to drop tranny again and looked inside with boroscope and starter removed and I don't get it. I did a fluid swap of tranny fluid too and tried dieselgeek shifter too thinking linkage I give up and will drive it until it goes I guess... Let me know what tried and if figure out please !
@@Hedgehodge- I had the clutch bled about a month ago to see if it would help. I even upgraded the clutch line and bleeder block. Still didn't correct the issue.
Hi there, is this works for Fiat sedici 2006 model
Can you bleed a brand new slave after it’s installed on to the trans and the trans is in the car. If the slave is new and not a pre bleed one ?!!?
Thanks so much for sharing
You are so welcome!
I assume this will work for a Ford m5 trans?
Thank you I’m on number three lol I’m hoping this one is good to go
Im putting my 3rd one in to. The air isnt getting all the way out you gotta bleed the master at an upward angle. And biy the pre filled internal slave
What does the hydraulic fluid actually push forward on? I'm confused about the routing of the hydraulic fluid internally.
I pushed the rod that actuates the clutch fork.
Would old oil cause gears to be hard to select and occasionally crunch gears?
No. Sounds like slave cylinder or the clutch itself
Any reason this wouldn't work with the transmission installed and slowly pressing the clutch pedal?
For the Dmax trucks with the slave in the trans and really no real other way to bleed, this saves a TON of time and headache.
Question, so why do we need to bleed brakes, if we can just pump the brakes to get the air out why is there a bleed nipple ?
My bleeder valve is broken, do you need to remove the transmission to replace it?
If its the bleeder on a Dmax master cylinder, no. The slave can be separated from the master at the junction at the master cylinder.
Thank you!
Zf5 has the same set up with small block fords
I have an ls1 t56 and the slave cylinder cannot be compressed by hand unless I open the bleed screw. Even with a clamp it won't compress. Maybe the fingers won't be able to compress it either is my concern. Have you run into this?
I haven’t, but honestly I don’t try to hand compress them a lot, for fear of tearing the internal o ring.
@@thoroughbreddiesel Thanks for the response! I found the reason though I don't fully understand it. I had my tilton master cylinder partially compressed to limit throw by use of a threaded eye attachment. Once i adjusted it to allow it to fully reset, the slave was able to move by hand. The master must block backwards fluid when partially engaged.
@@jacobrudolph4097I am running into the same problem right now, do you remember exactly what you did to solve it? Thanks!
@@dylanglin4222 I believe I took the adjuster off the master and bled it that way. It works great now so no concerns for functionality for me
Does this apply to nv3500 transmissions?
Does this apply to nv3500 transmissions?
Hi an you bleed this kind of slave cylinder without separating the transition from the engine
With this method no
Does pumping the clutch with the lid off do the same thing?
On the Dmax hydraulic setup, we couldn’t get it to bleed like that. This was much faster and effective.
Is there a way to bleed after install of slave?
That is what this video is about...?
@@thoroughbreddiesel no, not with the transmission out but everything back together.
So is there a way to bleed it with the transmission together?
What if transmission is already back bolted in can it still be bled
Yes.
How can it be bled
@@thermalslimeade exactly my question aswell
En espani no entiendo
Mine made a pop when I pushed it all the way in on the 15th push and lost all pressure…
Check to see if it broke through the firewall.
Trust me Ford has the same exact one I don't know why they've done that
I got a 95 f150.. same stupid save cylinder
Half the video is talking and the actual help doesn't start until half way through this 3 minute video...
What’s up guys .
