M 14 Injection system General instructions: All work on the injection system may only be done in the voltage and pressure-free state (disconnect battery). During all work on the injection system, cleanliness must be heeded in order to avoid the entry of particles into the injection system or the engine. After every loosening of a pressure tube, it must be replaced! Mounting of injectors on the engine Remove the protective caps only right before mounting.
Page 73
M 14 Injection system Fuel return line: max. number of plug assembly/removal (plugging in; locking; unlocking; removing the plug from the counter piece): 10x If during the removal of the plug connectors the O-ring on them is damaged, then the entire return line must be replaced. Before re-mounting of the plug connectors, it must be ensured that the counter pieces are not soiled or corroded.

Montageanleitung DPF chassisfest 05674600 CAUTION Danger of cutting! Sharp edges on the diesel particulate filter. • Wear personal protective equipment (cut-resistant gloves). DANGER Danger of fire from hot exhaust gas system. The exhaust gas system and, in particular, the diesel particulate filter can become very hot.

Montageanleitung DPF chassisfest 05674600 Installation of the pressure pipes/pressure sensor Step Description Attach the pressure sensor to the bracket using the cyl. screw M6x20. The temperature sensor plugs can be mounted on the bracket. Two threaded mounting positions are found on both the exhaust gas inlet and exhaust gas outlet.
Page 90
Montageanleitung DPF chassisfest 05674600 Coat the thread of the pressure pipes with Castrol Optimol TA and screw into the two threads facing up. Tightening torque: 45 ±5Nm. If you use your own pressure pipes, they must be at least 200mm long. To assemble the pressure pipe a clamping screw (056475XX) can be used, this can be obtained from Hatz.
Page 91
Montageanleitung DPF chassisfest 05674600 Connect the pressure sensor and the two pressure pipes to the 1000 mm hose and the 4 hose clamps. The hose must be divided to the desired lengths. Total length (pressure tube + hose): • Minimal 300mm (200mm pressure tube + 100mm hose) •...

Page 93
Montageanleitung DPF chassisfest 05674600 Pre-catalytic converter To prevent the diesel oxidation catalyst (DOC) from clogging, a pre-catalytic converter is used for low load/weak load applications. For chassis mounted DPFs, the pre-catalytic converter is available as an option from Hatz and must be mounted as close as possible to the DOC/DPF in the exhaust gas pipe.
Page 94
Montageanleitung DPF chassisfest 05674600 • Prevent water from entering into the exhaust gas pipe (e.g. flaps or suitable pipe elbows at the end). • When installing an exhaust gas pipe, an elastic intermediate part must be installed along the exhaust gas pipe to absorb the engine movement. The compensator must be attached close to the pivot point of the elastic bearing.
