I would go with Kurt’s measurement. I’m a measure once cut twice guy. Yes the 2F shroud fit correctly
I was not that much implying that one measurement was wrong than questioning if they were supposed to be the same. Original measurement from Kurt was with a FJ60 fan (which is too wide to fit in a 40/55 shroud if I followed correctly) and along the conversation you ended up with a Prado/Tacoma fan that should also have a negative offset.
I guess from your posts that before receiving these fan-clutch combo from Kurt you had a regular 2F setup and it was not fitting between the block and the radiator ?
So the FJ55 also have a smaller shroud for the 2F than for the F?
If I followed everything correctly between the 2 threads that would mean :
- FJ40 : up to 1974 big shroud, 1975+ small shroud for longer pump, 1977+ radiator moved forward to make room for clutch
- FJ55 : up to 1974 medium shroud, 1975+ very small shroud for longer pump, 1977+ no change because impossible to move radiator forward, 1979 thin radiator to accommodate clutch
So on a <=1974 FJ40 your fan+clutch+pump setup would fit but would still need a 2F shroud to have the airflow right ? (but would at least avoid the mess of moving the front cross member and radiator)
Ok I guess I should ask that on the other thread x)
Non related to this thread but interestingly enough the special pump/pulley/non-thermal-clutch for euro-spec 1974-1976 FJ40 (before the thermal-clutch in 1977) was indeed installed on the euro-spec FJ55 up to 1978 :
