This document provides instructions for restoring a machine after service work. It includes steps to reinstall underbody skid plates, clean work surfaces, start the engine and bleed air from the fuel system if needed, check filter and drain plug seals, test run the machine, check and top up fluid levels, operate the hydraulic suspension if oil was changed, and use a computer to read and erase error codes and reset service messages. The restoration process ensures the machine is ready for operation after maintenance or repairs.

8. Check that the valve clearance between the yoke and rocker arm's thrust sleeve is according to
. If needed, adjust as follows:
214 Valve system, specification
Adjust correct valve clearance for the inlet valves. Place a tool in adjusting screw B as counterhold and tighten lock
nut A with a box-end wrench. See .
214 Valve system, specification
Recheck the valve clearance.
NOTE!
Using a marking pen, mark when adjusting is done to keep track of which valves, unit injectors, and brake rocker
arms have been adjusted.

be according to .
214 Valve system, specification
Tighten adjusting screw B to contact and then half a turn so that the valve yoke is pressed downward and the
exhaust valves open slightly. Then the engine brake mechanism is heavily loaded and all parts are in correct
position.
Loosen adjusting screw B until the shim or feeler gauge can be slid in and out with some effort.
Lock adjusting screw B in this position with lock nut A, with torque, see .

NOTE!
The error check may never be used for adjusting work.
14. Adjust the rest of the valves, brake rocker arms, and unit injectors in the same way.
15. Check that the guide pin is located directly opposite the bowl in the spring plate. Tighten the bolts for the brake
rocker arms' leaf springs.

254 Exhaust aftertreatment system, tightening torques
the clamp closest to the burner part. Check that the outlet end has not been displaced so that the exhaust pipe is
leaning, then tighten the clamp. Tap on the clamps, start farthest from the bolt and tap both ways all the way
around. Remove the lifting devices.
15. Restore the machine from service position.
16. Run VCADS operation: 25456–3 (Reset ash load).
17. Start the engine and check that there are no leaks. Repeat tightening when needed.
