BJ74 fan blade size

[Eurasiaoverland]

Does anyone have a BJ74 fan blade to hand? I'm looking for a measurement of the blade diameter.

Thanks

I dont, but they are the same as a 80's Hilux in diameter, cant remember which one sorry. For my car I used a 1HDFTE fan and clutch and trimmed it till it fit well.

How do you make sure you're trimming it evenly so as not to throw it out of balance? I'm imagining an engine running with no fan shroud and a plane

I made a template, traced it onto each blade and linished down to the line.

That sounds safer, thanks for sharing.

My original non-fan clutch fan blade, 16361-47010 is about 408 mm across, with 6 blades. I want to have the parts for a fan clutch type setup as an option. I have a Megacruiser fan, 16361-41090 which is a 7 blade fan, approximately 430 mm in diameter. I have ordered an Australian BJ70 fan 16361-41070, also 7 bladed but which fits in the same shroud as my original fan (by comparing non-clutch and clutch type fans on BJ70s) and so I assume will be a perfect fit.

But in case this plan does not work out, I can trim one or other of the 7 blade fans.

Thanks
