Infidel I was just looking at your kdp jig in your gallery. I changed mine the hard way. But that jig is just a good looking unit. Wished I had of seen that before I repaired mine. But to make one I guess one would need the cover off to get the right measuerments. By the look of the jig I don't think you would even get your hands dirty and probably under an hour to complete. Nice piece of work.

 

It's not my work, and you are about right, 45 minutes to assure the dowel pin stays were it's supposed to.
The jigs are available from Harold for less than the cost of the crank seal.
