I tried all the guess work but still could not get it right.

A diesel place wanted to rebuild the whole IP for $2600

The plungers have two holes... one is "small" lowerer than the other "larg"
While the body of the pump has got two holes.

I have done lots of search but could not fine how to set the plungers back to their correct hole orientation.

Would any one able to help with setting the plungers back to the correct orientation please?

Highly appreciated


Regards,

Most likely, you do not need a rebuild. Besides, that is a bit pricey. PM me if you do need a new pump, I have them new from Germany, with warranty, for about half that.

You DO need to have it calibrated (not a DIY job) as moving internal parts and not getting them back to the exact same positions will easily cause what you're describing.
