This diesel engine, which is available in 55 kW (75 hp) and 66 kW (90 hp) versions, is based on the well-known swirl chamber diesel engine, but is complemented by the latest developments, including charge air cooling and direct fuel injection.
This engine therefore meets the EEC D3 emission standard and all other requirements for latest generation engines in terms of fuel consumption, smooth running, versatility, performance and power output.
Engine codes
Codes for Endura-DI engines:
- 55 kW/ 75 hp - BHDA
- 66 kW (90 hp) - C9DB
Location of engine code on Endura-DI engine block:
Crankshaft
The crankshaft, supported by five main bearings, has thrust half rings on the third main bearing, which determine the axial clearance of the crankshaft.
Timing sprocket located on the crankshaft
The sprocket located on the crankshaft drives the sprocket of the high-pressure fuel pump (injection pump) via a chain drive. The sprocket is fixed to the crankshaft by a central bolt, which creates a clamping force.
Belt drive of the gas distribution mechanism
| Pos. | Spare Part No | Name |
| 1 | - | Timing belt tensioner |
| 2 | - | Timing belt |
| 3 | - | Camshaft pulley |
| 4 | - | High pressure fuel pump pulley |
The timing belt is driven by the high pressure fuel pump pulley and transmits valve timing information to the camshaft located above.
CAUTION: Because a new timing belt will stretch considerably during initial installation, it is important to follow the adjustment instructions carefully.
The belt tension is provided by an automatic tensioner. The initial tension adjustment is performed using an adjustment cam.
The pulley is secured to the tapered shank of the camshaft. The required force for fixing the pulley to the camshaft is provided by the central bolt.
Valve lifter, adjusting shims
The "command" about the valve timing is transmitted to the valve springs via eight pushers.
CAUTION: When installing adjusting shims, the markings on them must face the tappets.
Adjusting shims are used to adjust valve clearances. The thickness of each shim is indicated on its reverse side.
Cylinder head
| Pos. | Spare Part No | Name |
| 1 | - | Hole for guide bushing |
| 2 | - | Identification of gasket thickness |
Cylinder head gaskets are available in various thicknesses. Depending on the piston protrusion on the engine, a gasket of a certain thickness must be used. The thickness can be determined by the teeth on the edge of the gasket.
CAUTION: Clean the gasket and mating surfaces thoroughly. Do not use sharp objects for cleaning.
The cylinder head gasket is an MLS (multi-layer steel) type gasket. The gasket consists of three steel layers. The steel layers have an outer rubber coating. Due to its design, the durability of the gasket is increased, and as a result of the gasket not being worn in during installation, the cylinder head mounting bolts can be inserted with a lower clamping force. However, due to the presence of a rubber surface, the gasket is also more susceptible to grooves, and therefore the surface should be pre-cleaned without the use of sharp objects.
Crankshaft oil seals
NOTE: The crankshaft rear oil seal is supplied with a locating sleeve. This aligns the oil seal with the crankshaft rear flange.
NOTE: The position of the crankshaft rear oil seal retainer must be verified using the special tool.
CAUTION: If the mounting sleeve is removed too soon, the oil seal will be compressed and become unusable.
Front and rear oil seals are made of PTFE and must be clean (non-greased) when installed.
Both oil seals are supplied with a mounting sleeve. The sleeve should not be removed until the assembly procedure is complete.
Crankcase ventilation
The PCV valve is located on the top surface of the cylinder head cover. To ensure optimum engine performance, this valve and all PCV hoses must be kept clean and free of any debris.
Oil pan
The oil pan is made of steel and is sealed with silicone-based sealant (WSE-M4G-323-A6).
CAUTION: When removing the front engine mount, do not place a jack under the oil pan to support the engine.
CAUTION: Support the engine and transaxle assembly with the oil pan flange on wooden blocks so as not to load the oil pan.
