there is a slot in the pump gear and a hole in the backing plate which
when the timing gears are lined up will pass the pump gear hole over a
hole in the pump body , in which you locate a pin in order to lock pump
and shaft in position .

Quick question, which direction do I turn a Bosch injector pump once the bolts are loosened , to increase timing on a 200 tdi.
I’m trying to diagnose low power up hills and high egt’s .
Hope you can help .
