SUBJECT

Difficulty Installing TDC Alignment Pin 11 0 300

SITUATION

The TDC Alignment Special Tool 11 0 300 is difficult to install into the engine block bore, or interferes with the low pressure fuel line support bracket, as described in the TIS repair instructions when checking or adjusting the engine mechanical timing.

Vehicles equipped with the N52 or N52K engine require a modification to the dowel pin portion, as shown in Fig 1.

Reduce the diameter (A) by 0.10 mm for the entire length (B) of the dowel pin.

Removing the black finish on the dowel pin with an emery cloth or the equivalent will be sufficient.

Do not drill or ream the engine crankcase hole.
