Engine, description
Machines of SN 1911001- / -1911499 and 1921001- / -1921499 are equipped with the DEUTZ-BF4M 1013 E engine.
Machines of SN 1911500- / -1913000 and 1921500- / -1923000 are equipped with the VOLVO-D5D engine.
Both engines are four cylinder, four stroke, in-line direct-injected diesel engines, with exhaust turbo and liquid cooling.
Machines fromSN 1913001- and 1923001- are equipped with the VOLVO-D5D engine.
he engine is a four-cylinder, four-stroke, in-line diesel engine with direct injection, exhaust turbocharger, liquid cooling and
internal, unregulated exhaust gas recirculation (EGR).
To comply with exhaust gas limit values, the turbocharger is equipped with unregulated, internal exhaust gas
recirculation (IEGR), which returns the exhaust gas within the cylinder head to the combustion air. The oxygen content of
this exhaust is low. A lower oxygen content reduces the temperature spike during combustion and thereby reduces nitrogen
oxide (NO ).
The camshaft has an extra cam - the trailing cam. This causes the inlet valve to briefly open during the exhaust stroke so that
exhaust gas also enters the engine intake system. In the subsequent induction stroke, this exhaust is sucked back in. There is
no regulation of exhaust gas quantity.
The engine data plate specifies model, engine number and power data. The engine number is also stamped into the
crankcase. Model and engine number must be specified when ordering spare parts. The direction of rotation is found on the
flywheel, anticlockwise. Firing order: 1-3-4-2 (cylinder no. 1 on the flywheel side).
IMPORTANT! Adjustments to the regulator may only be performed by trained staff in an authorized central repair
workshop.

If necessary, screw on adapter 9998007 for the connector.
4. Connect compression tester 9988539. Crank engine with the starter.
5. Carry out compression test on each cylinder.
Compression: 3 +0.8 MPa (30 +8 bar) (435 +116 psi)
NOTE!
The compression measured depends on the starter rpm during the measurement and the engine's altitude.
Therefore, exact limit valuescannot be set. Compression measurement is recommended only for comparison of all
engine cylinders. If a deviation of more than 15% is found, the cylinder in question should be dismantled to
determine the cause.
6. Install compression tester and connector.
7. Install injection valves.

Cylinder head, description 211 Service Information 2014/3/10
Profile:
CWL, L40B [GB]
Cylinder head, description
The cylinder head is made of cast iron. The inlet air enters vertically (A) and the exhaust gases exit horizontally (B). Inlet and
exhaust are on the same side of the cylinder head.
Figure 1
Cylinder head
The cylinder head gasket is a multi-layer gasket with 1, 2 or 3 identification holes to indicate the three different thicknesses.
The choice of gasket thickness is determined by the piston protrusion over the cylinder head sealing surface. If new pistons
or a new cylinder block are fitted, the gasket thickness must be evaluated and changed if necessary.

Valves, description 214 Service Information 2014/3/10
Profile:
CWL, L40B [GB]
Valves, description
The engines are equipped with one inlet and one exhaust valve per cylinder.
The upper area of the valve guide (on the valve stem) houses an O-ring (A). This O-ring seal should prevent a large level of
oil consumption and reduce the amount of hydrocarbons in the exhaust.
Valve rotation is achieved through the eccentric position of the rocker arm.
The valve springs have a prescribed direction of installation. The closely wound end of the valve spring must point toward
the cylinder head.
Rocker arm lubrication is a component of the centralized lubricating system. The oil is supplied via the tappets and push
rods.
Figure 1
Due to a new valve spring guide design, it is no longer possible to use a feeler gauge to adjust the valves of L40B machines
from SN 1913001 – / 1923001 – and L45B machines from SN 1943001 – / 1953001 –. For this reason, valve clearance
must be adjusted using the rotation angle disc.

Engine Service Guide

  • 1. Service Information Document Title: Function Group: Information Type: Date: Engine, description 200 Service Information 2014/3/10 Profile: CWL, L40B [GB] Engine, description Machines of SN 1911001- / -1911499 and 1921001- / -1921499 are equipped with the DEUTZ-BF4M 1013 E engine. Machines of SN 1911500- / -1913000 and 1921500- / -1923000 are equipped with the VOLVO-D5D engine. Both engines are four cylinder, four stroke, in-line direct-injected diesel engines, with exhaust turbo and liquid cooling. Machines fromSN 1913001- and 1923001- are equipped with the VOLVO-D5D engine. he engine is a four-cylinder, four-stroke, in-line diesel engine with direct injection, exhaust turbocharger, liquid cooling and internal, unregulated exhaust gas recirculation (EGR). To comply with exhaust gas limit values, the turbocharger is equipped with unregulated, internal exhaust gas recirculation (IEGR), which returns the exhaust gas within the cylinder head to the combustion air. The oxygen content of this exhaust is low. A lower oxygen content reduces the temperature spike during combustion and thereby reduces nitrogen oxide (NO ). The camshaft has an extra cam - the trailing cam. This causes the inlet valve to briefly open during the exhaust stroke so that exhaust gas also enters the engine intake system. In the subsequent induction stroke, this exhaust is sucked back in. There is no regulation of exhaust gas quantity. The engine data plate specifies model, engine number and power data. The engine number is also stamped into the crankcase. Model and engine number must be specified when ordering spare parts. The direction of rotation is found on the flywheel, anticlockwise. Firing order: 1-3-4-2 (cylinder no. 1 on the flywheel side). IMPORTANT! Adjustments to the regulator may only be performed by trained staff in an authorized central repair workshop.

Remove injection valves, see 237 Injectors all, testing and adjusting incl removing and fitting 1. Figure 1 Insert adapter (9998694) in injection valve bore with new seal ring. 2. Figure 2 Place clamping claw on adapter. Tighten screw.
  • 5. 3. Figure 3 If necessary, screw on adapter 9998007 for the connector. 4. Connect compression tester 9988539. Crank engine with the starter. 5. Carry out compression test on each cylinder. Compression: 3 +0.8 MPa (30 +8 bar) (435 +116 psi) NOTE! The compression measured depends on the starter rpm during the measurement and the engine's altitude. Therefore, exact limit valuescannot be set. Compression measurement is recommended only for comparison of all engine cylinders. If a deviation of more than 15% is found, the cylinder in question should be dismantled to determine the cause. 6. Install compression tester and connector. 7. Install injection valves.
  • 6. Service Information Document Title: Function Group: Information Type: Date: Cylinder head, description 211 Service Information 2014/3/10 Profile: CWL, L40B [GB] Cylinder head, description The cylinder head is made of cast iron. The inlet air enters vertically (A) and the exhaust gases exit horizontally (B). Inlet and exhaust are on the same side of the cylinder head. Figure 1 Cylinder head The cylinder head gasket is a multi-layer gasket with 1, 2 or 3 identification holes to indicate the three different thicknesses. The choice of gasket thickness is determined by the piston protrusion over the cylinder head sealing surface. If new pistons or a new cylinder block are fitted, the gasket thickness must be evaluated and changed if necessary. Figure 2 Cylinder head gasket, marking
  • 7. Service Information Document Title: Function Group: Information Type: Date: Valves, description 214 Service Information 2014/3/10 Profile: CWL, L40B [GB] Valves, description The engines are equipped with one inlet and one exhaust valve per cylinder. The upper area of the valve guide (on the valve stem) houses an O-ring (A). This O-ring seal should prevent a large level of oil consumption and reduce the amount of hydrocarbons in the exhaust. Valve rotation is achieved through the eccentric position of the rocker arm. The valve springs have a prescribed direction of installation. The closely wound end of the valve spring must point toward the cylinder head. Rocker arm lubrication is a component of the centralized lubricating system. The oil is supplied via the tappets and push rods. Figure 1 Due to a new valve spring guide design, it is no longer possible to use a feeler gauge to adjust the valves of L40B machines from SN 1913001 – / 1923001 – and L45B machines from SN 1943001 – / 1953001 –. For this reason, valve clearance must be adjusted using the rotation angle disc. Figure 2 Valve system
