I am curious if I should do anything in particular when starting it for the first time this weekend? Do I need to lube or oil anything in particular?
I will be bleeding the diesel
lines so I don't expect it to fire right off the bat. Hopefully the oil pump engages before I get fuel to the cylinders.
It's hard to know what you have done and haven't done with this engine prior to putting it in the boat. also it is unclear if and or how it was "preserved" for storage.
Taking a stored engine back to service
would have led to a lot of things on the bench prior to installing -
- complete check of all the rubber components
- replace impeller
- remove injectors and eyeball the cylinders for corrosion
- remove the valve cover and do the same
- new thermostat
- heat exchanger inspection
- light oil in cylinders (not too much lest hydraulic lock)
- replace oil filter
- change fuel filter
- provide a clean fuel source to the pump
- Spin engine by hand/drill adapter on bench to pre-oil the system
- observe fuel from injector supply lines - fuel system ops check
- remove fuel supply
- reinstall injectors
- turn engine by hand - confirm compression exists
- everything ready to go except coolant
Install in boat -
- Service coolant
- be prepared to top off when engine fires and bubbles are consumed.
- Bleed fuel system
- Raw seacock closed - prepare to open upon start or shut down after first start and open if seacock is in a dangerous place to operate when engine running
- start engine
Whether or not the engine starts should not be in doubt unless injector timing
All the bench prep can technically be done on the boat but it would have been easier on the bench.
