Marine diesel maintenance schedule



I'm looking for a very general marine diesel maintenance schedule, just to get an idea of time and $ involved. The engine is a Cummins 300 Hp turbo 5.9L.

X hours, clean this
X hours, change oil
Etc...

What are the items I should really pay attention to?

Figure every hour is 60-80 miles. Basically what I do with a tractor.

Not sure if this is the best way for marine engines.

I almost worked for a company in BR called Diesel Specialists on Choctaw. They rebuilt and did maintenance on just about every marine diesel motor. Try giving them a call

I just figure you drive 60 miles in an hour. Change oil every 3000-6000 in most diesels. Longer in some of the newer ones.

Marine motors not operating in the dust so oil should stay clean. I'm sure there are recommendations from cummins. Should be easy to email them.

It really depends on how you run it...at least that's how I treat my tractor. You run it harder you're gonna burn oil a lot faster. I guess changing it every 150 hrs would be a good place to start.

It's not going to be ragged out, but it's going to be run pretty much every day

re: Marine diesel maintenance schedule


For anybody interested, here's what I found:

Before every engine start:

Check Oil (level, color, smell)
Check belts (tightness, cracks, etc.)
Check hoses (cracks, leaks etc.)
Check coolant level
Check fuel filter bowl
Check Raw water strainer
Engine in nuetral?


After every start:

Check water discharge (is she spitting?)
Check for smoke (amount, color)
Check raw water weep holes (should be dry after running)
Listen for unusual noise/vibration
Visual Inspection (vibration, etc.)



50 hours or 6 months:

Change oil and oil filter (always together)
Check or replace primary fuel filter
Check transmission fluid levels
Check zincs (if provided)
Clean engine (touch-up paint if needed)
Complete Visual Inspection (including exhaust system & fuel tank)
Check O-ring on fuel deck fill (a major cause of water in fuel)
Check fuel vent is clear
Check packing gland

Check valve clearances


100 hours or 12 months:

50 hours/6 month checks
Check or replace secondary fuel filter
Do full engine survey going over all systems


200 hours or 24 months:

50 hours/6 month checks
Drain and flush coolant
Raw water impeller (inspect or replace)
Air filter (inspect or replace)
Engine alignment check
Transmission fluid
Exhaust elbow (inspect)


500 hours:

Replace hoses and belts
Rebuild/replace raw water pump
Check head torque
Check valve clearances
Injectors

Any disagreements?
