was wondering which pulley is this, i have a 91 3.0 and just took off the water pump and the pulley that's attatched (the one the spring attatches to) and did not find no washer behind it. Is it the number 2 idler pulley (water outlet housing? why is the washer so important, does it act as a spacer for proper timing belt alignment? here's the pic of the washer

The one on the left hand side of the picture http://www.off-road.com/toyota/tech/v6tbelt/0708.jpg
Not the center one at top...

 

It is the #1 idler pulley,or the tensioner pulley.The washer is to allow the tensioner to rotate with spring pressure to set the tension.

 

thanks for all your help, my idler pulley is slightly different than the picture I guess the 91's are different than the 92's and up. I looked and looked to see if I dropped that washer but can't seem to find anything, I'll try looking at a parts fiche or dealer, anyone got a 91 and earlier to confirm this?

 

just wanted to give everyone a update on my washer fiasco..TRDparts4u confirmed that there is no washer behind the idler pulley on my year 4runner which is 91, i suspect the 91 and earliers did not come with one. Thanks everyone for all your help..whew!!

 

Good deal...the guys over there are an enormous help when ya need it

 

Glad you found out. I was nervous when I did mine because I followed the same directions that you did, and it specifically said not to lose the washer. Disregard my PM.
