The right hand timing chain cassette come out of the engine..shaft

Customer Question

How does the right hand timing chain cassette come out of the engine? Our Mitchel system does not explain RH side, only the left and the jack shaft. Does the engine have to be removed? Do you have to use the listed specialty tools or is there a work around? (like the GM 3.4dohc)
