Does the injector pump have to be removed to be able to change the drive shaft seal?

Hello,

The injector pump does need to be removed in order to have clear access to the inner seal.

Keep in mind that the pump requires proper timing when installing, without it being timed correctly the engine might not run properly.

Since the Pregio was not sold in the United States, I am unable to provide you with replacement instructions.

Please let me know if you have any questions.
Thank you.
