1. Insert the locating pin T400 1 1 into the hole of the locking piece of the chain tensioner, gently pry open the locking piece of the sprocket tensioner, and at the same time press down the camshaft chain guide splint.

Secondly, use the disassembly tool CT 10352/ 1 to disassemble the control valve, which is left-handed thread.

Thirdly, align the colored links on the camshaft timing chain with the marks on the exhaust camshaft sprocket.

4. Align the colored links on the timing chain of the balance shaft with the marks on the crankshaft sprocket and the marks on the balance shaft sprocket of the intake/exhaust camshaft respectively. (Operation completed)

The extended data ignition timing instrument consists of sensor, signal conditioning module and flash device. The sensor includes a current clamp and a shielded junction box. The signal conditioning module consists of attenuator, comparator, trigger and other circuits. The flash device consists of transformer, trigger coil, thyristor and flash tube.

The ignition signal is obtained from the high-pressure cylinder bit line through the magnetic induction coil sensor. The sensor signal is gained or attenuated, filtered and shaped by the signal conditioning module, and then sent to the flash device for detection. Then the flashing device takes flashing as an indication, so that the tester can observe the position of the engine ignition timing rotation mark relative to the fixed mark.
