TechnoToyTuning Water Pump Pulley Issue (16v)

[androssyae86]

So first of all, I am running a rwd setup. However, my crankshaft pulley is from a fwd motor (my original rwd one got damaged) which should be ok to my understanding because the alternator and water pump pulleys line up with it; AC and power steering are another story but I'm not using either so it doesn't matter

My original rwd water pump pulley got damaged so I ordered an aftermarket pulley from T3, the "ae86, 4age" one and not the "aw11, 20v, fwd" off the T3 webpage

I also have a new rwd water pump from the dealership (part #16100) and a new fan clutch I got from Napa. The issue i'm having is that the studs on the water pump are too short. There aren't enough threads for me to tighten the fan clutch against the new T3 (rwd) pulley against my new rwd water pump. Never had an issue with the oem rwd pulley before

Anyone find a way to get around this? Is it possible T3 modified the pulley for an electric fan upgrade which may have affected the distance? any help is appreciated!

If no solution.. someone let me know if they have a rwd water pump pulley for sale. Looking to buy!

Thanks for reading

Just double nut the studs and remove them. Then install longer bolts.
You may have the wrong pulley????

There is not much room to play with when using the viscus fan and
OEM pulley... the studs are only just long enough. I'd guess that the
extra thickness of the T3 pulley is the problem. The studs will be metric
thread, but as suggested, if you can find some longer studs and swap
them in, you could have an answer.
