Bleeding the clutch.
After fitting all the pipes fill the master pump with DOT 4 brake oil. Make sure it doesn't run out while bleeding.
Very Important on a Puma is that you must not pump the pedal more than 5 time. as the Slave cylinder is Plastic and it can popout then you need to remove the gearbox.
So for example A person pumps 5 times (from the top to the bottom of the pedal, not halfs) then holds the pedal down. then the other person releases the air from the slave cylinder and then locks it. like this you repeat till there is no air traped in the line.
TD5's 300tdi 200tdi and Older Defenders bleeding is the same press around 5 times and hold then another person releases the air from the Slave Cylinder, like that repeat till there is no air in the line.
