Just a couple of observations to note for resetting the pump are that both keys are in line on the pump drive shaft. The pulley key ties in with the timing mark on it which in turn should be lined up with pumphead fuel outlet marked 'A' or Cylinder 1. (each outlet is stamped A to E for the 5 cylinders to tie up with the firing order).

Started cleaning up the K24wc turbine and compressor housings this evening. Very pleased as the turbine housing and turbo seems to be a very welcomed hybrid. There's a larger K26 turbine housing and the compressor housing is marked up AMG. So I now need to get the calipers out and measure all the specs.

The cam rollers can go in a multitude of ways - only 1 layout is right.....
Then you have to get the pulley on the shaft in the right position. That normally takes me 4-5 goes to get right.....
Calipers? What do you need them for - as they are from aldi they'll make a passable adjustable spanner so may come in handy.Last edited by regcheeseman; 16 April 2019, 10:24 PM.

That said, I've a set of Lidl ones in my drawer at work, they are fine for aerospace work despite the big label on the box where they cannot spell caliper.Last edited by regcheeseman; 16 April 2019, 10:27 PM.

I'll try a rebuild tomorrow.
