MBE 4000 ENGINE CRANKING TOOL

A special tool is required for this procedure: Engine Cranking Tool (J 46167 or 407 589 00 63 00) . ‪

The engine cranking tool (J 46167 or 407 589 00 63 00) is used for two separate functions: blocking and cranking. ‪

  • With the pin inserted, the tool blocks the flywheel ring gear to prevent rotation during removal and installation of the flywheel.
  • Without the pin, the tool can be used with a wrench to turn the flywheel and crankshaft manually.

    Note: The first time an engine cranking tool is installed on the engine to turn the flywheel, the teeth on the rotating gear may rub on the flywheel housing. This does not cause a problem and should not occur the next time the tool is used.

Engine Cranking Tool Installation

Install the engine cranking tool (J 46167 or 407 589 00 63 00) as follows: ‪

  1. Remove the two bolts holding the inspection cover to the flywheel housing. See Figure 41978 .

  2. Remove the pin from the engine cranking tool (J 46167 or 407 589 00 63 00) .
  3. Install the tool in the flywheel housing and secure with two bolts of sufficient length.

    Note: The inspection cover bolts are not long enough to install the engine cranking tool. Longer ones will be needed.

  4. As needed, insert the pin to lock the tool and block movement of the flywheel ring gear.

Engine Cranking Tool Removal

Remove the engine cranking tool (J 46167 or 407 589 00 63 00) as follows: ‪

  1. Remove the two bolts and the cranking tool from the flywheel housing. It is not necessary to remove the pin.
  2. Install the inspection cover on the flywheel housing with the two bolts. Tighten the bolts 25 Nm (18 lbft).

    NOTICE:

    The engine cranking tool must be removed from the timing case before starting the engine. Failure to do so could damage the flywheel ring gear.
