Need some help on removing clutch slave (please)

If it is to change the seal, not needed to remove the entire pump. If you need to remove the pump, like you mentioned, remove circlips above and it should come out to the top. But not easy !, Try to heat up the alu housing without burning the wires around. And with a piece of wood, beat on the outer ring of the lower side pump.

 

I do not recall ever removing a circlip with slave in place. Take out entire assembly.
It has been quite a while but I just do not recall it being very difficult.

It looks like the nuts were over tightened and completely closed the split in the clamp. That may be causing binding on the studs which might require some prying to get it off.

 

You have to remove the circlips (or stopring) to lift that pump out of the housing

why would you remove the circlip and pull it out of the aluminum housing rather than remove two M8 nuts and just pull it all off together (with the aluminum housing)?

 

The two M8 nuts are far easier to deal with rather than wrangling with the big circlip in the tight confines of where the clutch slave is located...

Also, upon re-installation, it should be much easier to get the aluminum housing back on the two studs as opposed to trying to get the circlip back on in that tight space....

 

Most of the time those studs are fused with the alu inside the housing holes so impossible to remove without braking something.

 

If that's the case, maybe some PB Blaster in the opening in the aluminum bracket followed by a large screwdriver from the top in that groove to gently open the bracket - mine came right off but I get what you are saying...

Never experienced that. On a Boxer either. They have always come off by hand.

 

You have the two nuts off. Provided the fluid line and linkage are disconnected, you should be able to just pull off the aluminum housing with the clutch slave - should slide right off those two studs

 

Yes it’s tight,, put car on Jack stands,
Disconnect and move wires out of the way.
Time to clean those connections,, tape and bag them. ,,
Then,
I use a standard pry bar-nail puller type.
next ,, I think I used a broom stick ,, like 18” long,,, pry it off.
note; When you re-install it,, drill out those two holes. There is No need, for them to be that precise,, other then to,, Stick like Glue.

 

I warned you something can brake ! It can be welded back and there is need to be perfect. Pump is secured with that span ring.

 

....."there is need to be perfect"...must be " there is NO need to be perfect" !!
You are lucky you did not brake the engine case bolt mountings. That would be a disaster. And those who mention "They have always come off by hand.",

 

When the slave seal leak it will flow under that pump, not going up to the bolts. That is why I mentioned not to try open that bracket but push pump up wards leaving that bracket untouched. This Alu material is very bridle. I try to leave pump and bracket untouched and only replace the seal in situ from the underside.

 

Wow, that is unexpected! I will definitely put some antisieze on that surface next time I do this job. I guess the brake fluid attracts moisture, and then seeps in and causes things to corrode/galvanic action.

 

i just replaced my slave cyl on my car ... i just purchased the car on 31 july 24 . i got it back to my home and found on inspection it leaking ... the repair went easy , what did shock me was my brake fluid was clean in the master cyl , but nasty in slave ... I am thinking that whomever had been flushing the brakes could not connect that the fluid in slave should be flushed at same time brake fluid is changed .... I am writing this as a warning ... next time you have your brake fluid serviced ... make certain your tech is doing the clutch bleeding too... I feel this whole experience was unnecessary if the tech had done a complete brake fluid replacement ... not just the 4 wheel calipers....
