Camshaft and crankshaft
SOURCE: setting crankshaft and camshaft timing
with crank pulley white mark on 0 remove both cam pulley covers and verify yellow painted notches are exactly on the T mark cast in the fwd cam bearing housings..IF u find that it ISNT 'in time' then remove tensioner located near crank pulley and very carefully manipulate the L and R cam sprokets to allow belt to removed from cam sprockets only... DoNOT rotate engine without T belt installed .Do NOT turn engine backwards.. ever.. be advised that should the cam timing be off by more than 3 teeth either way serious engine damage will result ..this series of engines utilizes variable intake camshaft adjustment .. This job is not for the american small block specialist of yesteryear.. even an experienced asian tech is gonna have a difficult time with this lexus .. its not quite the same engine the Tundra uses...Lexus only mods befuddle reg toyota techs
SOURCE: cannot get timing gear off crankshaft to replace- does not have chain.
The gear is press fit onto the camshaft. The proper way to repair it is pull the camshaft and have the gear pressed off and a new one pressed on.
At one time I had made tools to do this job without removing the cam from the engine. I no longer have the tools, they were borrowed and not returned.

It's more to it than aligning the marks since the cam pulleys turn about three times or more to one turn of the camshaft on this engine. You need to find someone that is experienced on this vehicle.

Belt covers need to be on. Timing mark on crankshaft (while on compression stroke) should line up with TDC mark on cover. then Camshaft mark, needs to line up by looking through access hole of cover, and align mark on cam sprocket with pointer on inside of belt cover.
