Contents: Adjusting the timing phases ⬇ Installation ⬇
Caution! Risk of engine damage if the timing belt jumps. Rotate the crankshaft only in the direction of engine rotation.
Rotate the crankshaft by the toothed pulley 2 fastening bolt in the direction of engine rotation, install the crankshaft, slightly before reaching the "TDC" position. Insert the crankshaft lock "T10490" into the crankshaft toothed pulley again. Rotate the crankshaft in the working direction until the "arrow" pin of the crankshaft lock enters, during rotation, the hole in the crankshaft cover.
Attention! Inaccurate setting of the "TDC" position leads to an adjustment error. When turning further than "TDC": turn the crankshaft 2 more turns and stop it shortly before "TDC", then lock the crankshaft from turning with the crankshaft lock "T10490".
The camshaft hub must allow itself to be fixed using the injection pump pulley lock "3359".
Re-fixing the fuel injection pump hub is hardly possible. A slight misalignment of the "arrow" holes does not affect engine operation.
In this case, the tension roller indicator "2" should be located in the middle between the protrusions "1" and "3" of the base.
Note: A lateral shift of no more than 5 mm is permitted.
If the conditions are met, then you can continue with the valve timing adjusted correctly. If the conditions are not met, then the valve timing must be adjusted.
Adjusting the timing phases
If the camshaft hub does not allow itself to be fixed, pull out the crankshaft lock "T10490" so much that its pin is released from the hole. Turn the crankshaft against the working direction of rotation, so that the piston of the first cylinder is set in a position slightly before "TDC". Then slowly turn the crankshaft in the working direction until you manage to fix the camshaft hub. After fixing, loosen the screws securing the toothed pulley of the camshaft.
D - the crankshaft lock pin "T10490" is located to the left of the hole
Turn the crankshaft in the working direction until the pin "arrow" of the crankshaft lock enters, during rotation, the hole in the crankshaft cover. Tighten the screws of the toothed pulley of the camshaft with a torque of 20 Nm.
A - the crankshaft lock pin "T10490" is located to the right of the hole
First turn the crankshaft slightly against the working direction of rotation. Turn the crankshaft again in the working direction until the locking pin enters, during rotation, into the hole in the crankshaft cover. Tighten the camshaft toothed pulley screws with a torque of 20 Nm.
Continuation with correctly adjusted or corrected valve timing
Remove the lock for the diesel fuel injection pump "3359" and the crankshaft lock "T10490". Rotate the crankshaft by the toothed pulley mounting bolt 2 in the direction of engine rotation, install the crankshaft, slightly before reaching the "TDC" position. Checking the valve timing.
Warning! Risk of engine damage! When tightening the camshaft toothed pulley bolt, never use the diesel fuel injection pump locking device "3359" as a stop.
If the camshaft hub can now be fixed, tighten the bolts "1" of the camshaft toothed pulley "pos. 8" finally, using the stop "T10172" with the adapters "T10172/11" for this. Finally tighten the nut "2" of the fuel injection pump toothed pulley "pos. 4", using the stop "T10051" for this. Checking the valve timing.
Installation
Installation in reverse order.
Note: Replace the gasket. Use original spring clamps similar to those installed at the factory to secure all hose connections.
Tighten lock screw "1".
