    When I started to work on my mark 28 that was on my rack for about 15 years, I did the water pump and found the locating pin for the impeller cup was missing. The special tools I picked up at auction and at the time, I had no idea what they were for.  Read the service manual and take your time pay attention to the springs and  pawls . I had success and so will you.
