I just did the fan pulley bracket on my 1995 LS400. Not as easy as some say but it is doable if you have enough tools and a whole Saturday to do it.
First,you should have a fan pulley wrench (Harbor Freight belt type) to hold the pulley while removing and installing the four nuts on the hub. Removal of the fan and clutch may be difficult if it is on tight but I used a long piece of steel bar and a hammer to knock the pulley loose by positioning the end of the bar at the back of the pulley and while holding the other end of the bar firmly with one hand and hitting the middle section of the bar with the hammer. the pulley will eventually come loose.
Removal of the upper radiator would also make the job a little easier.
You need to really loosen both the left and right plastic timing belt covers but you don't need to take them completely off.
The two 14mm bolts on the air conditioning compressor unit are a bear to locate and remove but I think I used a short box wrench or ratchet to get to those two bolts. You need to completely remove them.
Once you get the two nuts and three bolts holding the pulley bracket in place, you should then be able to start wiggling the bracket loose and you may need to bend back a metal tab by the a/c compressos to get the bracket free from the front of the engine. You will need to bend back the black circular portion of the passenger side timing belt cover while pulling the bracket free from the engine. Then you need to put the new bracket in place while fighting with and bending the two timing belt covers to get the bracket back into position. Also make sure to get all of the bolts and nuts back into position before tightening everything down. I hole this helps.
