    The pic of the 1Y crank above shows some kind of tin wheel with cut out similar to the petrol trigger wheel type. Are you 100% that is a 1Y crank?
    I have not come across this and as the IDI has no electronic pump control wonder if that is not maybe a TDI crank?

    Possibly it is a very late IDI one and is used for diagnosis or pump timing.

    The engine codes will be difficult to link to actual cars as there is such a large range with all the seat, skoda,vw, audi and ford:o vehicles that use them.

    The Diesel 1Y Crank has a Timing wheel mounted on it maybe off a PD Engine :thumbup:

    I do not think that can be a 1Y crank, 1Z possibly and if it is a PD engines crank it will have the long nose on it and will not be from either a 1Y or 1Z engine.
    1Y is the non turbo IDI engine (pre TDI) fitted to early mk3 golfs, ventos, passat and the like.
    It will have the same dimensions as most of the diesel cranks with regard to main, crankpin journal sizes and stroke so could be used to do a similar job as the 1Y crank but the wheel makes it harder to lighten them for performance use.

    Interestingly though it appears to be a forged crank so maybe the TDI engines got higher grade cranks than the IDI or non turbo engines.

    Just a quick note to update if anyone is interested. Early (pre 88) KR 1.8 16v cranks are sometimes forged. I have just had my original 1987 KR engine apart and the crank is forged. It is also still within standard bearing size tolerances after 225k miles. Quite pleasing to see. :)

    Can anyone advise how I identify a crank and where the part numbers would be located?

    I have a modified block (EV based) but no idea which crank (hence stroke) is fitted to calculate the CC.

    Pistons appear to be BMW 84mm type so dependant on the crank it could be anything from an 1870 to a 2057 unit.

    GX vs KR

    a little more research on 1.8 GX and 1.8 KR crankshafts

    in the picture below is a KR engine forged crankshaft
    [​IMG]

    now comparing this to a GX cast crankshaft:
    up - KR forged crankshaft
    down - GX cast crankshaft
    [​IMG]

    left - GX crank
    right - KR crank

    Interesting. I wonder if a GX is the same as a DX etc?

    Another study: '96 AGG engine vs '91 2E Engine:
    AGG engine - cast crankshaft, no oil squirters, single valve springs, different pistons than 2E's.
    2E engine - forged crankshaft, oil squirters, dual valve springs.

    I'll take some pictures as soon as I can.

    2.0l 8v ABK, 3A, AAD, AEE, ADW (most Audi engines) > Forged(s) 053105101C (without trigger wheel)
    2.0l 8v AGG, ADY, 2E > Cast (058 block)053105101K, Seat part #'s suggest use ABF unit.

    And just to add part numbers for the diesel cranks we tend to use, or not, as the case may sometimes be,

    028105101L 1z

    028105101J 1y, ahh, afn

    On the 1y crank, the part number seems to just have 028J stamped on it, aswell as other numbers and letters on other parts.
    NA is also stamped on it. Non aspirated maybe?

    i didn't write the kr crankshaft part number, but from all the KR, PL, 2E, PG, PB engines i've seen...they all had a forged crankshaft.
