No. They are a normal Righ-Hand thread: 'righty tighty/lefty loosy' :-) The Crank pulley IS very tight (hopefully) upwards of 120/ft-lbs is normal torque. Check http://www.ultimatesubaru.org/forum for info on 'how to ' remove. TD
No,it is right hand thread.
Answerif you mean the external pulley on an EJ20...(the crankshaft pulley running the a/c and alternator belts) it is a 22mm socket (same as a 7/8" socket) and is loosened by using a good half inch drive breaker bar and socket. The crank pulley bolt is torqued to 130 ft/lbs. and will be difficult to move, but will eventually break free. It uses conventional right-hand threads. Whatever you do, DO NOT follow some internet advice and jam the breaker against the frame or garage floor and then crank the engine. This is not recommended by Subaru, is extremely dangerous and you could both damage your car and cause a serious injury this way. There is a special tool Subaru sells to hold the pulley so it doesn't spin while you take the bolt off. You can also stop the crank from rotating by putting the car in gear and setting the parking brake. If it's an automatic, you can lock the flywheel by using a large screwdriver or small pry-bar inserted in the flywheel inspection hole. I repeat, do not crank the engine with any tools attached to the pulley.
A ratchet and socket on the bolt that holds the crank pulley on.A ratchet and socket on the bolt that holds the crank pulley on.
That pulley is a press fit type. There are not any threads. You will need to rent/buy some pullers for that power steering pulley.
Only if you want to lose your hand.
No
The bolt on the tensioner pulley are opposite of a standard thread. That is, righty loosey lefty tighty. I know this first hand because I stripped the threads on my pulley trying to remove it on my 94 Sub.
They are standard right hand threads.
Left hand threads clockwise to loosen
Not all crankshaft pulley bolts are left hand thread. In my experience if it is a left hand thread the bolt head normally has an L stamped on it to notify the direction of thread
The crank bolt is right thread on a 96 geo metro. bob.
It is standard right hand thread. Righty tighty, lefty loosey.
