Clutch Pedal Master Cylinder on 7211

[irish7211]

The clutch pedal master cylinder on my 7211 seems to be worn as it is leaking quite a bit. Does anyone know what is involved in fitting a new one. Is it a complicated task?

A step by step approach would be appreciated.

open up 4 bolts M8 to take the entire pedal into the cab. Use the space you've got to release the oil lines and bolt the cylinder off the back of the pedal baseplate.

remount in reversed order.

Some folks found it handier to open the hood, remove the front panel of the cab, between hood and cab, and enter from there.

It was a couple of years ago that i did all 3 masters of the 5245, but i do remember taking off and remounting the oil lines had to be done one by one while shoving the assembly into the hole in 2 steps, mounting 1 brake line at a time. it was a 1.5 hour job, including an hour of figuring out how to tackle the job

Many thanks for your reply. This is certainly very helpful. I think its easier to get in from the front of the cab - there seems to be more room to work.

I presume when you mention oil lines these are carrying brake fluid. Also am I right in saying that when the master cylinder has ben replaced the clutch must be bled via the bleed screw on the slave cylinder?

Thanks again

I dont remember bleeding it back then, however the air was on top of the circuit anyways...

Hi

Yes it will need bleeding.

I just replaced the master clutch cylinder yesterday on 8540 following Renzes directions. Straight forward from within the cab, except the feed -in union which you do from in front of cab. Had to bleed afterwards.... now I have to do the slave which is not so cheaply priced-20 master 45 for slave.
Anything I need to know about replacinging the clutch slave; other than it was more likely to be the problem than the master!!
