Engine lubrication oil
The Craftsman Marine diesel engines are supplied
without lubrication oil.
Before commissioning the engine for the first time, it
must be filled with 5 liters of lubrication oil for diesel
engines, with following specifications:
Type: 15W40
API: CD, CE or CF4
CCMC: D4 or D5
The engine can be filled with oil through the filler cap
on the rocker cover or through the filler pipe at the
front of the engine.
When the filling of oil is completed, check
with the dipstick whether the level of
lubricating oil is correct.
A second filler cap is located at the starboard side,
next to the engine identification tag.

Gearbox
Gearbox
The gearbox is located at the rear of the engine and it
must also be filled with the correct type and quantity
of lubricant.
Craftsman Marine diesel engines are supplied with
gearboxes of several brands and t ypes.
For the ZF-Hurth and Technodrive brands the types
and quantities are specified here below:
Please consult the appropriate instruction manuals in
the case of other gearbox makes and models.
Here it is shown how the gearbox can be filled up with
its lubricant. When the filling is completed, verify with
the dipstick whether the correct level of fluid is
obtained.
ZF Hurth
Type ZF 10: 0,35 liter ATF
Type ZF 12: 1,1 liter ATF

Cooling liquid
Prior to commissioning the engine for the first time,
the inner cooling circuit must be filled with cooling
liquid.
In order to do so, the filler cap on top of the heat
exchanger housing must be removed.
Alternatively: if and when an expansion tank is fitted,
remove the cap on top.
The cooling system must be filled with 6,5 liters of
cooling liquid. You can fill the system with a ready-touse product, or prepare a mixture of 40% anti-freeze
(on the basis of ethylene-glycol) and 60% of clean tap
water.
Never fill the cooling system with sea
water! Never fill the cooling system
with sea water!
Fill the system to about 1 cm below the bot tom of the
filler pipe. The system will breathe automatically. Do
not forget to put the filler cap in place again and
tighten the breather bolt.
Once the engine being commissioned and having run
for the first time, verify again the level of the cooling
liquid and top up, if necessary.
