Undertaking a major overhaul of various systems

Undertaking a major overhaul of various systems on the boat.

First on the list was to fix a small, but persistent fuel leak (3/4 cup per hour) coming off of the main fuel injection pump assembly where the throttle linkage attaches.

This component took a professional mechanic almost two hours just to get off the engine (a Perkins 4-108).

I took the pump into Everglades Diesel in Fort Lauderdale and they broke it down for a look.

The pump has a surprising number of parts - at least 30, possibly more, and is complicated almost to the level of a transmission. Its insides were somewhat filled with oil, which it should not have had, and there were obvious signs of bad seals and scratches to the inside of the main cylinder where a thing like an impeller pumps the fuel at high pressure.

Anyway, due to the level of effort to get the device on and off the motor and the number of possible fault points on it, I elected to have a major overhaul done - at a cost of $768.

The pump came back looking so good I was ready to cuddle up with eat - like it was a brand new $3000 pump.


Here is the result of their work:
