Intro
The following are the steps I developed when installing service kits for my two Whale Gusher Galley Mk 3 foot pumps. These pumps have been manufactured since 1984, so I suspect they will be found on most all of our boats. The service kit is part number AK0553. It is widely available. I bought my kits on eBay. They looked like old stock, but the parts were fine. I have serviced two pumps, so I have limited experience. The following procedures worked for me. But, they may not all be correct (please mention any needed corrections) and certainly are not the sole way to accomplish this task.
Naming Parts
I found a pump exploded view with names for most of the kit parts. I could not find a view which names each pump part. So, I made up some part names to help with my description. My inventions are listed below and shown in Figure 1:
