If the intermediate wheel has been dismantled a nominal adjustment of the camshaft compared to the crankshaft (timing) must be made as follows:
1) The crankshaft is turned to TDC (top dead centre) for cylinder no 1.
Cylinder numbering, see page 500.11.
2) Roller guide for fuel oil pump cylinder no. 1 is mounted and the camshaft is turned in a position where the roller guide rests on the cicular part af the cam, see fig 1.

exhaust valve
Cam for fuel oil pump
Seen from front edge
Fig 1.
3) The "nominal size" is measured with a depth gauge, i.e. the distance from the upper edge of the roller guide house to the thrust gauge pressed into the roller guide, see fig 2.
"Nominal size"
Fig 2.
4) The camshaft is turned - in the engines direction of rotation (see page 500.12) - until the "nominal size" (as described in item 3) is reduced with the lead, mentioned in "Lead of Fuel Pump".
Note: "Lead of fuel pump" is shown in the table "Adjusment after the trail" in the Shop Test Protocol.
5) When items 1 - 4 are completed and correct the intermediate wheel can be mounted and tightened up again (torque moment, see page 500.40).
For adjustment of the single fuel oil pumps (separately and assembled), see working card 514-05.01.

Roller Guides
The fuel injection pumps and the rocker arms for inlet and exhaust valves are operated by the cams, on the camshaft through roller guides. The roller guides for fuel pump, inlet and exhaust valves are located in bores in a common housing for each cylinder, this housing is bolted to the engine frame.
The roller runs on a bush fitted on a pin that is pressed into the roller guide and secured by means of a lock screw.
Operating Gear for Fuel Injection Pumps
The injection pumps which are mounted directly on the roller guide housing are activated via thrust pieces from the roller guide.
The roller is pressed down on to the cam by a spring, which is fixed between the roller guide and the foot plate of the fuel injection pump.
Operating Gear for Inlet and Exhaust Valves
The movment from the roller guides for inlet and exhaust is transmitted via the push rods the rocker arms and spring-loaded valve bridges to each of the two valve seats. The bridge is placed between the valve spindles and in the one end it is provided with a pressed-on thrust shoe and in the other end it is fitted with a thrust screw for adjustment of the valve clearance.
On its top the bridge is controlled by a spherical thrust shoe on the rocker arm and at the bottom by a guide which rests in a spherical socket in the cylinder head.
