How do I replace the engine shut off switch?
i have been looking all over the internet and can't find any videos or even an explanation on how to replace the engine shut off valve. i have a 1984 Mercedes 300D turbo diesel. i see where the valve is however there is only about 2 inches between the injection pump and the oil filter housing and the valve is right in between. - do i need to remove either to get the valve out? - do i need to drain the oil to change the valve? - is there a specific way the valve is set into the injection pump?
