OK , What is THIS !

[Zeroroll]

I got the mainshaft seal replaced. Machined a "spacer ring" to fit the OD of the 1.6TD pump to the ID of the opening in the IP bracket,out of brass.
 This is an ALH engine and I'm using the stock pump bracket. The OD of the Electronic TDI pump was much larger. Also had to machine away that black plastic timing belt cover, on the engine side, but only behind the IP pulley,in a circle 1/16" larger than OD of IP pulley. The back side of the pulley would rub on it otherwise.

  I cannot install a cold start lever on the pump anyway,due to using the stock ALH IP bracket. No clearance,so it doesn't matter that there is not one on this pump.
 
 Anyone come up with any info for me on this pump? Very curious.
