I did not pull the camshaft pullys, only need to if camshaft seals leaking, not likley
to loosen the crank pully, I used an impact gun. (i know, bad for rod bearings, but what ya going to do) the best thing is a cheep chain wrench, and insulate the pully with a old serpentine bely or rubber tube.
you are going to need a harmonic balancer puller. on line for $10, sears $20
Tensioner. inspect the tensioner shaft for oil leak (small wetness is ok) Compress the shaft with a vice, then when its compressed, put a 1/16 or 3/32 drill bit thru the hole to keep it compressed, till its installed back on the engine
get a chiltons manual, worth the $20
you can turn the cams by hand, but its hard. I used a large pair of pliars with rubber handles. put the rubber handles in the "spokes" of the cam sprokets, then use a large screw driver or pry bar to turn the pliars/sprokets, a little primitive, but works. but like I said, with leather gloves, you can turn the cams.
I just inspected seals, I would not replace unless leaking. same with tensioner

almost same moter as lexus, but tundra does not have distibuters, or coils that shows in these pictures. I used a new chiltons manual. VERY HELPFULL!
