Danger! | Risk of explosion as fuel vapors can ignite. Risk of poisoning from inhaling fuel vapors and exposed handling of fuel. Risk of injury if fuel splashes hit the eyes. | No fire, naked flames or smoking. Avoid formation of sparks. Wear protective gloves and, if appropriate, safety goggles when handling fuel. | |
6 | Remove injection pump | ||
7 | Swivel engine in repair stand 180° | When this is done, the tappets drop in their guides toward the cylinder head. | |
8 | Spin the crankshaft in the direction of rotation till the scribe marks (4) on the crankshaft gear (2) and the camshaft sprocket (3) match | ||
9 | Pull out camshaft | ||
| Inspect | ||
10 | Inspect camshaft | Check the hardness, concentric running, cam elevations, dimensional accuracy, cracks, score marks and center holes. | |
Hardness of cams and journals | |||
Camshaft variation in concentricity | |||
Camshaft bearing journal diameter at all bearing points | |||
Peak-to-valley height of journals | |||
Centering hole of input side and output side | |||
| |||

| |||
| |||
If the camshaft has - a radial runout or - scores in the bearing journals: | |||
Repair camshaft | |||
Check the camshaft once again after repair. Ensure that the camshaft journals and the camshaft bearings match; change the camshaft bearings if required: | |||
Remove/install camshaft bearings | |||
| Install | ||
11 | Push camshaft into crankcase (1) | The marked tooth (4) of the crankshaft sprocket (2) must be positioned between the marked teeth (4) of the camshaft sprocket (3). | |
12 | Install timing case | ||
13 | Measure axial play of camshaft | ||
| |||
| |||
Axial play of camshaft | |||
If the reading is more than the prescribed value, check the thrust plate and replace if required. For this step: | |||
Remove timing case | |||
14 | Install injection pump | ||
15 | Fit on rocker arm bearing brackets | ||
16 | Install transmission | Model 613.355 with transmission 714.668 TRANSMISSION 613.355 in MODELS 455, 485, 714.690 with CODE 691cylinder cut-out system | |
