I got a 1HZ fan pic. Are you trying to swap fans or clutch?

i just finished a 1HZ swap into a HJ60 and the fans will interchange bolt to water pump but the 1HZ fanis 1/2 bigger across the plastic...

Fan .. my fan clutch still working fine ( hope ! :) )

Means share the same bolt pathern to the fan clutch, thought can trimm a little bit the blades if comes necesary ..
 
I'm happy to confirm that the 1HZ/1HD-T fan and the 2H fan share the same bolt pathern, and new my Tencha have a 8 blade 1HZ fan ( little bigger ) and 1HZ fan cluth .. with my heating problem solved ..

Need to perform a little mod in the fan shroud... ( top section ) to allow the new bigger fan spin freely ..

How much clearance between fan and radiator? The 2H fan is quite thin looking from the side

1" are not much really .. but thought it's enought ..
 
On a related note, do the 1HZ and 1HD-T share the same fan clutch? I've seen a bunch of fan clutches on ebay marketed as 1HZ clutches but wasn't sure if it would fit the 1HD-T.

Yes they are the same. The landcruiser fan clutches are also colour coded ith a dab of paint but I cant remember which colour is for a 1HZ HD T
 
Thanks rosco. I was thinking about maybe trying the blue fan clutch mod and if so I wouldn't mind picking up a spare fan clutch off ebay and trying it on that. But all the Oz ebay listings say 1hz clutch and list it as suitable for hzj cruisers not hdjs.
 
Well well .. On sat have got time to made my custom fan shroud .. not the best that I can do, but haven't much time .. here how it come ..

Looks the same, but aren't .. I cut the top part of the factory due to my new fan rub on top DS of the factory shroud .. well actually still doing .. but much less ..

Those 1HD-T blades are huge .. !

Go to your local parts .. ask for a 1HZ fan and compare it with yours .. check for actual clearance with your shroud and let figure ..
