Well, the EW12 crank fits in an Xu10j4 block, the XU9J4 crank fits in an Xu10j4 block , so by inference the EW/DW 10 crank ought to fit in the XU9J4 block. Big end diameter is correct but not sure about the big end diameter ontheDW10 crank. On the EW10 crank they are 45mm but may be 50mm on the diesel one. The EW12 crank  has 50mm big end journals

Conversely, the 86mm XU10J4/R/RS crank doesn't fit an XU9 block.

Ah. Not spotted that one . Is that the thrust journal , as the bore spacing is the same ?

PS. First road / circuitrace on Sunday. Closed circuit , one hour plus three laps . In the ‘over 65’ category, but the pace will still  be frantic  as we old gits  all try to kill each other .

Yes, thrust journal. Enjoy the racing. At least they're usually on nice bikes. Remember to have some slow release carbs prior. And stay off the front! Let some other poor old bastard do the work. Most importantly, don't burn all your matches too early.

what about the thrust journal makes it not fit?

 

ive had an xud9 crank in an xu7, also the 92mm xud11 did sit in there but would not turn a full revolution, I think the counterweight in some area was fouling a big end cap or block casting slightly

Too wide. Drop one in and see how you go.
