Since there isn't a tech page on the new site, I'll post it here. I found that both injection pumps on my 6bta-330M3 engines leaked a little bit of oil from the small freeze plugs so I decided to have them rebuilt as a winter project.
I used Advanced Marine Diesel for the job. It took a few weeks to have an injection shop to do the job. The pumps were reinstalled in early December. Then came the rain, Then, I found I had a 6 x 6 blue tarp wrapped around my prop. Then, I found the shifter mechanism on the starboard Zf220A transmission was locked up and need it's own maintenance.
I lost several weeks with these unexpected problems but everything is back together now. Bob and I took it out for a test run on the 13th. The engines sound much quieted and are smoother at all rpms. Fully loaded the engines made 2920 rpm and 30.6 kts. 20 psi of boost. Now, I can hope for better fuel economy.
If you have ZF200A transmissions, the shift mechanism is a maintenance item. If shifting isn't smooth, you might need to take it apart and grease the parts. I used water proof trailer bearing grease. Removing the drift pins and the circlip for is a challenge. You'll need a good set of tools to do the job
Good info Bill. It is maintenance season 🙂 Glad you are back up and running.
Nice project Bill. Those C330 were humming.
Bill's next project was to replace injectors on both engines.
They really sound nice
Good job Bill! I can finally get in this site... Update on my freshwater flush, still working and getting used to the 3 minutes of fresh water per engine when I return. Can't say I see a difference until I open them up and inspect the Aftercooler and Heat exchanger, but the peace of mind is nice.
The new Raymarine CP 570 Sounder booster is working well and although it doesn't replace the beam width of my B265LH ducer, it adds better definition and added 1 KW so now it's 2kw. Pretty cool and I can see DSL now.
