VIII MAINTENANCE - RECOMMENDED OIL TYPE - REFILLING The engine could be damaged if allowed to operate with insufficient oil. It is also dangerous to add too much oil as its combustion could sharply increase the rotation speed. Use a suitable oil in order to protect the engine. The lubrication oil influences the performances and life of the engine in an incredible way.
DISASSEMBLY AND REASSEMBLY Besides disassembly and reassembly operations this chapter also includes checking and setting specifications, dimensions, repair and operating instructions. Always use original RUGGERINI spare parts for repair operations. Flywheel extraction Use extractor cod. 00365R0020, as shown in figure 1.

Piston diameter check: The diameter of the piston must be measured at approximately 18 mm from the base (fig.19). Engine Diameter mm RD210 RD 211 89,919 ÷ 89,930 RD270 RD278 94,920 ÷ 94,935 Check the clearance between cylinder and piston, if it is greater than 0.120 mm both cylinder and piston must be replaced.

CHECKS AND OVERHAUL Crankshaft Whenever the engine is dismantled, particularly for the replacement of cylinders and pistons due to wear caused by the aspiration of dust, it is good practice to check the condition of the crankshaft. 1. Remove the plugs “A” from the oil passages (fig.23). 2.
CHECKS AND OVERHAUL Governor lever and spring Check that the shoes (S, fig. 30) are level and that the springs have not lost their elasticity. Renew any excessively worn parts after consulting the spare parts catalogue. Supplement and governor spring dimensions (fig. 30): Lenght Lenght under Load...

ENGINE ASSEMBLY Notice: These instructions are valid for engines up-dated prior to the publication of this manual. Any modifications must be checked on the technical circulars. Before assembling the engine carefully clean all parts and dry them with compressed air. Lubricate moving parts to prevent seizing when starting up.
ENGINE ASSEMBLY XIII Crankshaft preparation The insertion of the main distribution gear onto the crankshaft must be carried out while hot. Heat by means of dry heating or an oil bath at 70/80 °C (fig. 53). Upper crankcase preparation 1. Insert accelerator internal lever onto crankcase taking care not to damage the oil seal O-Ring.
8. Insert oil seal rings on the drive side of the crankshaft (fig. 58). A warped oil retainer may allow the introduction of air into the engine thus causing crankcase ventilation problems. Use genuine oil retainers with the RUGGERINI. 9. Mount lower crankcase complete with studs, centering pins and bearings.
A warped oil retainer may allow the introduction of air into the engine thus causing crankcase ventilation problems. Use genuine oil retainers with the RUGGERINI. The oil seal rings are to be fitted with the arrow pointing in the same direction of the crankshaft rotation.
After insertion of the bearings into the big end, attach connecting rods to crank pins, bearing in mind that an arrow, on the pistons for RD210-211 , indicates the rotation direction of the engine (fig. 66). The combustion chamber, which is eccentric with respect to the axis, should be turned to the nozzle side.
ENGINE ASSEMBLY XIII Piston ring fitting Fit rings onto pistons in the following order (fig. 68): RD210-211 1. Chromed compression seal ring. 2. Torsional compression seal ring (with internal notch turned upwards). 3. Expander oil scraper ring. RD270-278 1. Chromed compression seal ring.
Before mounting the heads on the cylinders, insert injectors in their housings and after having secured them temporarily, check protusion of nozzles from head surface (fig. 75). Protusion S should be: Engine RD210 RD 211 2,25 ÷ 2,75 RD270 RD278 3,75 ÷ 4,25 COMPILER TECO/ATI REG.
Adjustment is effected by inserting copper washers between the injector and injector supporting faces on the heads (fig. 76). Washer thickness 1 mm (RD210-211) and 0.5 mm (RD270-278). Fitting cylinder heads Insert oil seal O-rings on rocker arm housing and fit the cylinder head in place.
XIII ENGINE ASSEMBLY Injection pump fitting Fit injection pump into timing case inserting adjusting shim between supporting flange and crankcase (fig. 80). To facilitate the insertion of the pump, rotate the flywheel so as to bring the actuating cam to rest position and set the rack bar in a half way position.
Should the flywheel need to be replaced, the top dead center compression position of the pistons is to be determined as per page 40 and the start of injection according to the following table: Engine I.P. Ø flywheel RD210-211 26° 53,5 mm 236 mm RD270 27°...
ENGINE TESTING Speed adjustment 1. With engine hot set minimum speed at 1000 RPM (fig. 88) and maximum to idle (fig. 89) at: 2100 RPM for RD 278 engine 3150 RPM for RD 210 engines 3700 to 3750 RPM for RD 211 engines 2.
ENGINE TESTING Testing engine on brake After having placed the engine on the brake (fig. 92), proceed with the following operations: 1. Check oil level (fig. 93). 2. Start engine and run at minimum speed. 3. Check oil pressure on pressure gauge (fig. 90). 4.
STORAGE Storage Prepare engines as follows for storage over 30 days Temporary protection (1/6 months) • Let engine run at idling speed in no-load conditions for 15 minutes. • Fill crankcase with protection oil MIL-1-644-P9 and let engine run at 3/4 full speed for 5/10 minutes. •...
