Check, correct position of bracket of TDC sensor - AR03.00-P-1101-03HA
Bracket of TDC sensor
| Number | Designation | Engine 604 | Engine 605, 606 | |
|---|---|---|---|---|
| BE03.00-P-1001-01A | Piston stroke at 20° ATDC (setting position of bracket of TDC sensor) | mm | 3.35 | 3.23 |
- Screw dial gauge holder (2) into the prechamber bore of cylinder 1.
- Set piston of cylinder 1 to about 10° BTDC.
- Fit dial gauge (1) with tracer pin onto dial gauge holder (2).
- Set tracer pin on the dial gauge (1) to a preload of about 5 mm.
- Slowly crank engine further in direction of rotation at the front of the crankshaft until the pointer of the dial gauge (1) stops (TDC position).
- Set scale of dial gauge (1) to zero.
- Slowly crank engine further in direction of rotation of crankshaft until the dial gauge has moved back by the piston stroke at 20° ATDC.
After the dial gauge has moved back (crankshaft position 20° ATDC), the pin (4) in the crankshaft belt pulley or in the vibration damper must be positioned exactly below the bracket of TDC sensor (arrow).
- Insert fixing pin (03) into the bracket of TDC sensor (17).
- The pin (4) in the crankshaft belt pulley or in the vibration damper must engage in the slot of the fixing pin (03) (arrow).
- If the pin does not engage, correct the position of the bracket of the TDC sensor (17).
- To do this, slacken bolt (23) and move bracket of TDC sensor (17) sufficiently until the pin (4) in the crankshaft belt pulley or in the vibration damper engages in the slot of the fixing pin (03).
- Tighten bolt (23).
