Mike-
I haven't removed/reinstalled my fuel injection pump but have researched what needs to be done. The timing alignment is very straight forward. There is a hairline scribe mark on the pump's mounting flange. That scribe mark needs to be aligned with a matching mark on the engine's mounting flange. I'm considering a rebuild on my pump, so I checked it out this last weekend. To get to it, you need to remove the alternator. Once you do that you'll see the pump is attached to the engine via three studs/nuts. The bottom one will be hard to get to. At the top most stud/nut connection, there should be a hairline scribe mark on the pump's flange. The matching scribe mark on the engine flange should be directly across from it. My engine had both scribe marks, but the pump was offset clockwise about 3/16" which concerned me a little. I've got an email into Westerbeke to gage their reaction to the slight advance - haven't received a reply yet. However, I'm having my injectors rebuilt at Boston Fuel Injection, who I've worked with many times in the past. They indicated that it has been a relatively common practice to advance the timing slightly on older engines to reduce smoking, and I should probably leave it where it is. BTW, my pump seems to be working OK, but I also have slight leakage at the o -rings described by others. Looking forward to their experience at replacing the o-rings.
As I wrote earlier, I've had great experiences with Boston Fuel Injection (with my W50 and other diesel engines over the past 25 years). They have been very honest with me, been quite responsive, have given me great advice when trouble shooting problems. Their phone number is 617-884-5151. They quoted me $600 to rebuild my fuel injection pump about 2 years ago, but advised me to hold off rebuilding it based on the very minimal leakage I was getting. I like that honest advice. They were right. They engine continued running very well, and I lived with the small amount of fuel leakage.
